text: Mirabell and Millamant, equally strong-willed, discuss in detail the conditions under which they would accept each other in marriage (otherwise known as the "proviso scene"), showing the depth of their feeling for each other. Mirabell finally proposes to Millamant and, with Mrs. Fainall's encouragement (almost consent, as Millamant knows of their previous relations), Millamant accepts. Mirabell leaves as Lady Wishfort arrives, and she lets it be known that she wants Millamant to marry her nephew, Sir Wilfull Witwoud, who has just arrived from the countryside. Lady Wishfort later gets a letter telling her about the Sir Rowland plot. Sir Rowland takes the letter and accuses Mirabell of trying to sabotage their wedding. Lady Wishfort agrees to let Sir Rowland bring a marriage contract that night.


title: The Way of the World

text: By Act 5, Lady Wishfort has found out the plot, and Fainall has had Waitwell arrested. Mrs. Fainall tells Foible that her previous affair with Mirabell is now public knowledge. Lady Wishfort appears with Mrs. Marwood, whom she thanks for unveiling the plot. Fainall then appears and uses the information of Mrs. Fainall's previous affair with Mirabell and Millamant's contract to marry him to blackmail Lady Wishfort, telling her that she should never marry and that she is to transfer her fortune to him. Lady Wishfort offers Mirabell her consent to the marriage if he can save her fortune and honour. Mirabell calls on Waitwell who brings a contract from the time before the marriage of the Fainalls in which Mrs. Fainall gives all her property, in trust, to Mirabell. This neutralises the blackmail attempts, after which Mirabell restores Mrs. Fainall's property to her possession and then is free to marry Millamant with the full £12000 inheritance.

text: The epigraph found on the title page of the 1700 edition of "The Way of the World" contains two Latin quotations from Horace's "Satires". In their wider contexts they read in English:


title: The Way of the World

text: In 1700, the world of London theatre-going had changed significantly from the days of, for example, "The Country Wife." Charles II was no longer on the throne, and the jubilant court that revelled in its licentiousness and opulence had been replaced by the far more dour and utilitarian Dutch-inspired court of William of Orange. His wife, Mary II, was, long before her death, a retiring person who did not appear much in public. William himself was a military king who was reported to be hostile to drama. The political instabilities that had been beneath the surface of many Restoration comedies were still present, but with a different side seeming victorious.


title: The Way of the World

text: One of the features of a Restoration comedy is the opposition of the witty and courtly (and Cavalier) rake and the dull-witted man of business or the country bumpkin, who is understood to be not only unsophisticated but often (as, for instance, in the very popular plays of Aphra Behn in the 1670s) either Puritan or another form of dissenter. In 1685, the courtly and Cavalier side was in power, and Restoration comedies belittled the bland and foolish losers of the Restoration. However, by 1700, the other side was ascendant. Therefore, "The Way of the World's" recreation of the older Restoration comedy's patterns is only one of the things that made the play unusual.


title: The Way of the World

text: The 1688 revolution concerning the overthrow of James II created a new set of social codes primarily amongst the bourgeoisie. The new capitalist system meant an increasing emphasis on property and property law. Thus, the play is packed with legal jargon and financial and marital contracts. These new legal aspects allow characters like Mrs. Fainall to secure her freedom through an equitable trust and for Mirabell and Millamant's marriage to be equal through a prenuptial agreement.


title: The Way of the World

text: This shift in social perspectives is perhaps best shown in the characters of Fainall and Mirabell, who represent respectively the old form and new form of marital relations: sexual power at first and then developing into material power.


title: Light fighter

text: A light fighter or lightweight fighter is a fighter aircraft towards the low end of the practical range of weight, cost, and complexity over which fighters are fielded. The light or lightweight fighter retains carefully selected competitive features, in order to provide cost-effective design and performance.


title: Light fighter

text: A well-designed lightweight fighter is able to match or better a heavier type plane-for-plane in many missions, and for lower cost. The lightweight class can therefore be strategically valuable.


title: Light fighter

text: In attempts to scale this efficiency to still lower cost, some manufacturers have in recent years adopted the term “light fighter” to also refer to light primarily air-to-ground attack aircraft, some of which are modified trainer designs. These lower cost lightweight attack aircraft have become known as light combat aircraft (LCA's), and are sometimes considered to include some multirole light fighters.


title: Light fighter

text: From 1926 the light fighter concept has been a regular thread in the development of fighter aircraft, with some notable designs entering large-scale use.


title: Light fighter

text: A key design goal of light/lightweight fighter design is to satisfy standard air-to-air fighter effectiveness requirements at minimum cost. These criteria, in order of importance, are the ability to benefit from the element of surprise, to have numerical superiority in the air, to have superior maneuverability, and to possess adequate weapon systems effectiveness. Light fighters typically achieve a surprise advantage over larger aircraft due to smaller visual and radar signatures, which is important since in the majority of air-to-air kills, the element of surprise is dominant. Their comparative lower cost and higher reliability also allows for greater numbers per budget. Finally, while a single engine light fighter would typically only carry about half the weapons load of a heavy twin engine fighter, its surprise and maneuverability advantages often allow it to gain positional advantage to make better use of those weapons.


title: Light fighter

text: A requirement for low cost and therefore small fighters first arose in the period between World War I and World War II. Examples include several RAF interceptor designs from the interwar era and French "Jockey" aircraft of the immediate pre-World War II. None of these very light fighters enjoyed success into World War II, as they were too hampered in performance. Similar to the meaning of lightweight fighter today, during World War II the term “small fighter” was used to describe a single engine aircraft of competitive performance, range, and armament load, but with no unnecessary weight and cost.


title: Light fighter

text: The modern view of light/lightweight fighters is as a capable weapon intended to satisfy the main criteria of air-to-air combat effectiveness, which in order of importance, are:


title: Light fighter

text: 1. Superiority in the element of surprise, to be aware of the enemy before they are aware of you. In past combats, surprise advantage has been mostly based upon small visual and radar signatures, and having good visibility out of the cockpit. Surprise is a significant advantage, since historically in about 80% of air-to-air kills, the victim was unaware of the attacker until too late.


title: Light fighter

text: Small fighters like the F-5 with a planform area of about or the F-16 at about , compared to about for the F-15, have a much lower visual profile. The small fighter is typically invisible to opposing pilots beyond about , whereas a larger fighter such as the F-15 is visible to about . This is a non-linear advantage to the light fighter opposing a heavy fighter. Additionally, smaller targets take longer to visually acquire even if they are visible. These two factors together give the light fighter pilot much better statistical odds of seeing the heavy fighter first and setting up a decisive first shot. Once the small fighter sees and turns towards the opponent its very small frontal area reduces maximum visual detection range to about .


title: Light fighter

text: Given similar technology, smaller fighters typically have about two thirds the radar range against the same target as heavy fighters. However, this cannot be counted upon to give the large fighter a winning advantage, as larger fighters with typical radar cross sectional area of about are detectable by a given radar at about 50% farther range than the cross section of the light fighter. This approximately balances these trade-offs, and can sometimes favor the lightweight fighter. For example, from the front the F-15 actually presents about radar cross sectional area, and has been typically defeated by opposing F-16 forces not only in close dogfighting combat, but also in extensive Beyond Visual Range (BVR) trials. Also, airborne fighter radars are limited: their coverage is only to the front, and are far from perfect in detecting enemy aircraft. Although radar was extensively used by the United States in the Vietnam War, only 18% of North Vietnamese fighters were first detected by radar, and only 3% by radar on fighter aircraft. The other 82% were visually acquired.


title: Light fighter

text: The modern trend to stealth aircraft is an attempt to maximize surprise in an era when Beyond Visual Range (BVR) missiles are becoming more effective than the quite low effectiveness BVR has had in the past.


title: Light fighter

text: 2. Numerical superiority in the air, which implies the need for lower procurement cost, lower maintenance cost, and higher reliability. Not even taking into account the sometimes superior combat capability of lighter aircraft based on surprise and maneuverability, the pure numbers issue of lower cost and higher reliability (higher sortie rates) also tends to favor light fighters. It is a basic outcome of Lanchester's laws, or the salvo combat model, that a larger number of less-sophisticated units will tend to be successful over a smaller number of more advanced ones; the damage dealt is based on the square of the number of units firing, while the quality of those units has only a linear effect on the outcome. This non-linear relationship favors the light and lightweight fighter.


title: Light fighter

text: Additionally, as pilot capability is actually the top consideration in maximizing total effectiveness of the pilot-aircraft system, the lower purchase and operational cost of light fighters permits more training, thus delivering more effective pilots. For example, as of 2013, total heavy F-15C operating cost is reported at US$41,900 per hour, and light F-16C cost at US$22,500 per hour.


title: Light fighter

text: 3. Superior maneuverability, which in maneuvering combat allows getting into superior position to fire and score the kill. This is a function of achieving lower wing loading, higher thrust to weight ratio, and superior aerodynamics. This is sometimes described colloquially as “wrapping the smallest possible airframe around the most powerful available engine.” Professional analysis through 4th generation fighters shows that among heavier fighters only the F-15 has been generally competitive with lighter fighters, and its maneuvering performance is exceeded by several lighter fighters such as the F-16. Light fighters have no inherent aerodynamic advantage for speed and range, but when designed to be as simple as possible they do tend to have lower wing loading and higher thrust to weight ratio. Additionally, smaller fighters are lower in inertia, allowing a faster transient response in maneuvering combat.


title: Light fighter

text: 4. Weapon systems effectiveness. This area is one where the light fighter can be at a disadvantage, since the combat load of a single engine light fighter is typically about half of a twin engine heavy fighter. However, modern single engine light fighters such as the General Dynamics F-16 Fighting Falcon and the Saab JAS 39 Gripen generally carry similar cannon and air-to-air missile fighter weapons as heavier fighters. Actual aerial combat in the modern era is of short duration, typically about two minutes, and as only a small fraction of this is spent actually firing, modest weapons load outs are generally effective. The ideal weapons load for a modern fighter is considered to be an internal gun and two to four guided missiles, a load that modern light fighters are fully capable of while maintaining high agility. For example, the JAS 39 Gripen, despite being the lightest major fighter in current production, carries a combat load of a 27mm cannon and up to six air-to-air missiles of the same types as carried by heavy fighters. Additionally, combat experience shows that weapons systems "effectiveness" has not been dominated by the amount of weaponry or "load out", but by the ability to achieve split second kills when in position to do so.


title: Light fighter

text: Superior technology has often been quoted as a strong factor favoring the heavy fighter. The specific argument usually presented is that heavy fighters have superior radar range and longer range BVR missiles that take advantage of that range. This radar range advantage is one of the major reasons for the existence of the modern heavy fighter, but it has not turned out to be a significant advantage in air combat history to date for several reasons. A major reason has been because long range BVR missile shots have often been unusable, and often unreliable when they could be taken. The weight of the larger missiles also reduces performance and range needed to get in position to fire. Due to these factors, between 1958 and 1982 in five wars there were 2,014 missile firings by fighter pilots engaged in air-to-air combat, but there were only four beyond-visual-range kills.


title: Light fighter

text: The more general and often misunderstood argument for more technology that has been historically assumed to favor heavy fighters is not just better radar but better systems support for the fighter pilot in other ways as well. Examples include all weather capability, precise electronic navigation, electronic counter-measures, data-linking for improved information awareness, and automation to lighten pilot workload and keep the pilot focused on tasks essential to combat. This was a compelling argument, as the greatest factor in the effectiveness of a fighter plane has always been the pilot. Quoting a prominent reference, "Throughout the history of air combat, a few outstanding fighter pilots, typically less than five percent of the whole, have run up large scores at the expense of their less gifted brethren. The numerical imbalance was such that a large number of high scorers was needed. The quest was on to turn each fighter pilot into an ace, and technology seemed the easiest, and the only way to achieve it. This was the idea underlying the first two American superfighters; the F-14 Tomcat and the F-15 Eagle.”


title: Light fighter

text: While the technology advantage for heavy fighters that better supported the pilot may well have been a valid point in the 1970s (when the F-14 and F-15 first entered service), this advantage has not been maintained over time. Engine performance improvements have improved load carry capability, and with more compact electronics, the lightweight fighter has, from the 1980s onwards, had similar pilot enhancing technical features. The lightweight fighter carries equally effective weapons including BVR missiles, and has similar combat range and persistence. The modern lightweight fighter achieves these competitive features while still maintaining the classic advantages of better surprise, numbers, and maneuverability. Thus, the lightweight fighter natural advantages have remained in force despite the addition of more technology to air combat.


title: Light fighter

text: Due to their lower costs, modern light fighters equip the air forces of many smaller nations. However, as budgets have limits for all nations, the optimum selection of fighter aircraft weight, complexity, and cost is an important strategic issue even for wealthy nations. The budgetary and strategic significance of light fighters is illustrated by the defense investment at stake. As an example where well referenced data is available, though numerous trial and combat references consider the lightweight F-16 to be as good or better on a per plane as the excellent but expensive F-15, fielding and maintaining a light fighter force based on the F-16 is approximately half the cost of the same number of F-15's. The US Air Force reports the total loaded cost per hour (as of 2013) of operating the F-16C to be ~US$22,500 per hour, while that of the heavy F-15C is $41,900 per hour. Numerous authoritative sources report that it takes about 200 to 400 flight hours per year to maintain fighter pilot proficiency.


title: Light fighter

text: Lanchester's laws on military superiority suggest that any technical superiority of the heavy fighter on a unit basis will not always translate to winning wars. For example, late in WWII the greatly superior German Messerschmitt Me 262 jet fighter, flown by the finest pilots Germany had left, many of them very high scoring aces with kill counts far in excess of Allied pilots, in its relatively small numbers suffered heavy losses and was unable to fundamentally alter the air war over Germany. Such issues are relevant to future military planning and deployments.


title: Light fighter

text: The light fighter class originally stemmed from concern at the growing size and cost of the frontline fighters in the 1920s. During the late 1920s and 1930s the light fighter would receive significant attention, especially in France.


title: Light fighter

text: One early light fighter project was the French Air Force's 'Jockey' interceptor program of 1926. Several aircraft, including the Nieuport-Delage NiD 48 and Amiot 110, were trialed without much success as they offered little over aircraft already in production In the late 1920s the British similarly issued specification F.20/27 for a short-range fast-climbing daylight interceptor. The de Havilland DH.77 and Vickers Jockey monoplanes were among seven designs tendered to meet the specification but neither went into production, the heavier but faster biplane Hawker Fury being preferred.


title: Light fighter

text: Despite the failure of their Jockey program, the French returned to lightweight fighters during the 1930s as a means to expand France's fleet of aircraft and counter the buildup of the German air force. This focused on light wooden fighters that could be built quickly without affecting production of other aircraft. A mid-thirties specification requiring fixed undercarriage produced two prototypes and in 1936 a revised requirement for retractable gear resulted in three prototypes. The most numerous of the two designs which went into production was the Caudron C.714. Delivery began in early 1940, but less than 100 had been built before the fall of France. Although underpowered, it was of necessity used by Polish air force pilots serving in France.


title: Light fighter

text: There was debate before and during World War II about the optimum size, weight and number of engines for fighter aircraft. During the war, fighters in the light to middle-weight range proved to be the most effective. Properly designed with competitive power to weight and thrust to drag ratios, these aircraft out-performed heavy fighters in combat due to greater surprise and maneuverability. They were also more cost effective, allowing greater numbers to be deployed as a combat advantage. Some single-engined fighters (including the P-51 Mustang and A6M Zero) could also match or beat the range of their heavy twin-engined counterparts.


title: Light fighter

text: The German Messerschmitt Bf 109 entered service in 1937 as a high speed interceptor and became the most-produced fighter in history, with nearly 34,000 built. The design philosophy of the Bf 109 was to wrap a small airframe around a powerful engine using Messerschmitt's "lightweight construction" principle, which aimed to minimize the weight and number of separate parts in the aircraft. By concentrating wing, engine and landing gear weight in the firewall, the structure of the Bf 109 could be made relatively light and simple. The Bf 109 was the second-smallest major fighter aircraft of World War II and the lightest in the European theater. The "E" version used in the Battle of Britain had an empty weight of 2,010 kg (4,431 lb). The more heavily armed and powerful G version used later in the war had an empty weight of 2,700 kg (5,900 lb). In comparison, its main fighter opponents weighed 2,100 kg (4,640 lb) to 5,800 kg (12,800 lb).


title: Light fighter

text: The lightest major fighter of World War II was the Japanese Mitsubishi A6M Zero naval fighter. Entering service in 1940 and remaining in use throughout the war, it had an empty weight of 1,680 kg (3,704 lb) for the A6M2 version, which was extremely light even by the standards of its time. The design team leader, Jiro Horikoshi, intended it to be as light and agile as possible, embodying the qualities of a samurai sword. With Japanese engine technology lagging behind that of the west, but required to out-perform western fighters, the designers minimised weight to maximize range and maneuverability. This was achieved by methods including the use of light weaponry and the absence of armour and self-sealing fuel tanks. Early in World War II the Zero was considered the most capable carrier-based fighter in the world, and the extremely long range meant that the Zero could appear in and strike locations where Japanese air power was otherwise not expected to reach. In early combat operations, the Zero gained a reputation as an excellent dogfighter, achieving a kill ratio of 12 to 1. However, Japan was unable to keep improving the aircraft through the war, primarily limited by lagging engine technology, and by mid-1942 a combination of new tactics and the introduction of better aircraft enabled the Allied pilots to engage the Zero on equal or superior terms. For instance, the larger and heavier Grumman F6F Hellcat had superior performance to the Zero in all aspects other than manoeuvrability. Combined with the US Navy's superior training standards, units equipped with the type achieved a large victory-to-loss ratio against the Zero and other Japanese aircraft.


title: Light fighter

text: The Royal Air Force entered World War II with two modern single-engined fighters forming the majority of the fighter force of the RAF – the Supermarine Spitfire and the Hawker Hurricane. Initially introduced as bomber interceptors, both started with eight machine gun armament but changed to cannons in the course of the war.


title: Light fighter

text: The Spitfire, designed by R. J. Mitchell, entered service in 1938 and remained in production throughout the war. The empty weight of the Battle of Britain-era Spitfire IIA was 2,142 kg (4,723 lb), increasing to 2,984 kg (6,578 lb) in a later variant. It was highly maneuverable and was generally a match for its German opponents. Most Spitfires had a Rolls Royce Merlin engine, but later variants used one of the most powerful engines of the war – the Rolls Royce Griffon. The Spitfire was produced and improved throughout the war but was complex to build and had limited range. In other respects it was considered an outstanding fighter.


title: Light fighter

text: The Hawker Hurricane played an important role in the Battle of Britain, but its performance was inferior to the Spitfire and during the war was removed from frontline duty as a fighter and used for ground attack. Production ceased in mid-1944. The Hurricane IIC weighed 2,605 kg (5,745 lb) empty.


title: Light fighter

text: On the eve of the war, the United States Army Air Corps contracted for several "very light" fighter designs based on the Ranger V-770 engine, an air-cooled inverted V12 engine, that delivered up to 700 hp. Two prototypes were the Bell XP-77 (empty weight ) and the Douglas XP-48 (empty weight ). Problems with the engine and performance and a perceived lack of need saw both programs canceled. However, they were specifically defined as "light" or "very light" fighter aircraft.


title: Light fighter

text: Instead, the US developed a number of standard pursuit fighters, the most efficient being the relatively lightweight North American P-51 Mustang. The P-51 was more economical, costing less per air-to-air kill than any other American aircraft.


title: Light fighter

text: The United States Navy, also made aware of lightweight advantages by combat results, ordered a lighter version of the Grumman F6F Hellcat, which at empty weight had limited maneuverability and rate of climb. The planned Grumman F8F Bearcat replacement used the same engine, but with empty weight reduced to had excellent performance. It entered production too late to see combat in World War II. Postwar, it equipped 24 fighter squadrons in the Navy and a smaller number in the Marines. Navy author James Perry Stevenson called the Bearcat "the quintessential lightweight fighter".


title: Light fighter

text: The Soviet Yakovlev Yak-3, which entered service in 1944, was an attempt to develop the smallest and lightest fighter around the V-12 Klimov M-107 engine. As this engine was not available in time, the Klimov M-105 was substituted, with a resulting empty weight of 2,100 kg (4,640 lb). Despite the reduced power, the Yak-3 had a top speed of 655 km/h (407 mph). The Yak-3 could out-turn the German Bf 109 and Fw 190. German pilots were ordered to avoid dogfights with the Yak-3 at low level.


title: Light fighter

text: The Soviet Yakovlev Yak-9 was also a lightweight fighter, initially using the M-105 engine. With an empty weight 2,350 kg (5,170 lb), it was among the lighter major fighters of World War II. A development of the Yakovlev Yak-7, it entered combat in late 1942 and was the Soviet Union's most-produced fighter with 16,769 built. At low altitudes, the Yak-9 was faster and more maneuverable than the Bf 109. However, its armament of one cannon and one machine gun was relatively light.


title: Light fighter

text: The Luftwaffe's Heinkel He 162 "Volksjäger" of 1945 was a very deliberate attempt at producing a low cost jet fighter without materials that were in short supply at the end of the war. It was a low cost emergency fighter, one of several designs for the Emergency Fighter Program using rockets or jets, which could be built by unskilled labour and would be flown by inexperienced pilots to defend the Third Reich. With an empty weight of 1660 kg (3,660 lbs), it was very light even for the time. The He 162A was powered by a BMW 003 engine. With a top speed of 790 km/h (491 mph) at normal thrust at sea level, and 840 km/h (522 mph) at 6000 m (19,680 ft), it was about 130 km/h (80 mph) faster than Allied fighters but had no more than 30 minutes fuel. Test pilots reported it to be a fine handling and conceptually well designed aircraft, and considered its problems to be rushed delivery more than any fundamental design flaws. It never formally entered operational service, and did not receive the benefit of being flown by well trained pilots using a well considered operational plan. Only 120 were delivered to units, and it scored only a few kills in experimental use before the war ended.


title: Light fighter

text: After World War II fighter design moved into the jet era, and many jet fighters followed the successful World War II formula of highly efficient mostly single-engine designs. Prominent early examples include the British mid-50s Folland Gnat, the American North American F-86 Sabre, Northrop F-5 and the Soviet Mikoyan MiG-15.


title: Light fighter

text: The Mikoyan-Gurevich MiG-15 was a Soviet jet fighter developed shortly after World War II. It weighed 3,630 kg (8,003 lb) empty and was one of the first successful jet fighters to use swept wings for high transonic speeds. It first saw service in the Chinese Civil War. In combat during the Korean War, it outclassed straight-winged jet day fighters. Some 18,000 were produced.


title: Light fighter

text: The North American F-86 Sabre, a transonic jet fighter manufactured from 1949, was the United States's first swept wing fighter. With an empty weight of 5000 kg (11,000 lb) it was nearly 40 per cent heavier than the MiG-15, but light compared with today's fighters. The F-86 had a bubble canopy, small size, moderate cost, high maneuverability, and an armament of six calibre machine guns. It could turn faster than any modern fighter. It saw combat against the Mig 15 in high-speed dogfights during the Korean War. Considered (with the MiG 15) as one of the best fighters in the Korean War, it was the most-produced Western jet fighter, with total production of 9,860 units. It continued as a front-line fighter in numerous air forces until 1994.


title: Light fighter

text: The Folland Gnat was a British private venture design for a light fighter and was the product of "Teddy" Petter's theories about fighter aircraft design. Although only adopted by the UK as a trainer, the Gnat served successfully as a fighter for the Indian Air Force and was in service from 1959 to 1979. India produced an improved derivative of it, the HAL Ajeet. With an empty weight of 2,177 kg (4,800 lbs) it was the lightest successful post-World War II jet fighter, though at the cost of shorter range compared to other fighters. The Gnat is credited as having shot down seven Pakistani F-86s in the 1965 war, for the loss of two Gnats downed by PAF fighters. During the Indo-Pakistani War of 1971, Indian Gnats shot down several Pakistani F-86s without loss. The Gnat was successful against the capable F-86 flown by well-trained Pakistani pilots because its smaller size allowed a superior level of surprise and greater agility in dogfighting.


title: Light fighter

text: In the early 1950s, the NATO NBMR-1 competition for a cheap "light weight tactical strike fighter" able to carry conventional or tactical nuclear weapons and operate from dispersed airfields with minimum ground support led to designs including the French SNCASE Baroudeur, Breguet Taon and Dassault Étendard VI, the Italian Aeritalia G.91 and Aerfer Ariete. Other competitors included the Northrop F-5A. The British chose to continue production of the Hawker Hunter, while the French decided to work independently of the competition. Italy produced the Fiat G.91 while the competition was underway and, in 1957, this was selected as NATO's standard strike fighter. With an empty weight of 3,100 kg (6,830 lbs) it was very light for a jet fighter. The G.91 entered service with the Italian Air Force in 1961, with the West German "Luftwaffe", in 1962, and later with the Portuguese Air Force. It was in production for 19 years, with production ceasing in 1977 with 756 aircraft built.


title: Light fighter

text: In the mid-1950s, it was realized that fighter costs were escalating to possibly unacceptable levels, and some companies sought to reverse the trend to heavier and more expensive fighters. A prominent result was the Mach 1.3 to Mach 1.6, 4335 kg (9,558 lb) Northrop F-5. Smaller, cheaper and simpler than the contemporary F-4 Phantom, the F-5 had excellent performance and was popular on the export market. It was perhaps the most effective US-produced fighter in the 1960s and early 1970s, with a high sortie rate, low accident rate, high maneuverability, and an effective armament of 20mm cannon and heat-seeking missiles. Though the United States never procured the F-5 for main line service, it did adopt it as an opposing forces (OPFOR) "aggressor" for dissimilar training role because of its small size and similarity in performance to the Soviet MiG-21. It also participated in large scale trials of aircraft and missile effectiveness. In the extensive 9 month long AIMVAL/ACEVAL trial at Nellis AFB in 1977, the F-5 "Red Force" was quite effective against the considerably larger F-14 Tomcat naval fighter and F-15 Eagle single seat fighters making up the "Blue Force". These modern aircraft are approximately five to ten times more expensive than the various versions of the F-5. The final result was the F-5 fighting the more modern fighters to an effective plane for plane draw. In direct combat against the similar MiG-21 (which performed well against American fighters in Vietnam), the F-5 is known to have scored 13 victories against 4 losses. Just under 1000 of the F-5A Freedom Fighter were sold worldwide, and another 1,400 of the updated F-5E Tiger II version. As of 2016 the F-5 remains in service with many nations, some of which have undertaken extensive upgrade programs to modernize its abilities with digital avionics and radar guided missiles.

text: The light middleweight Saab 35 Draken was a second to third generation Mach 2 fighter produced from 1955 to 1974 and in service for 45 years, with empty weights from 6,577 kg (14,500) to 7,440 kg (16,400 lbs). It was a double-delta wing single-engine fighter. Its steeply swept inner delta wing allowed for a high cruise speed. The double-delta, with a shallower rake at the outer wing, improved maneuverability. It was designed to be cheap enough for small countries and simple enough to be maintained by conscripted mechanics. Its high acceleration, light wing loading, and extreme maneuverability enabled it to be an excellent dogfighter. However, it had an overly complex fire control system. It remained in service until 2005.


title: Light fighter

text: The French Dassault Mirage III is another late 2nd/early 3rd generation delta wing Mach 2 fighter. Stemming from a French requirement for a lightweight all-weather interceptor, it has been in service since 1961. With an empty weight of 7,076 kg (15,600 lbs) in the "E" version with added ground attack capability, the Mirage III is a light fighter by modern standards (though twice as heavy as initial Mirage I). Its maneuverability, modest cost, reliability and armament of 30mm cannons and heat seeking missiles proved effective. It served the French Air Force and was exported to many countries. It performed very well for Israel in the Six-Day War of 1967 and Yom Kippur War of 1973. However, Argentina's Mirage IIIs were out-performed by British Sea Harriers during the Falklands War of 1982.

text: Similar in size to the F-5, the Russian Mikoyan-Gurevich MiG-21 entered service in 1959, was produced until 1985, and is still in widespread use today. The late Generation 2 to Generation 3, Mach 2 MiG-21 has an empty weight of 4535 kg (10,000 lbs), and has served nearly 60 nations. It shot down 37 to 104 US Phantoms, in the Vietnam War, with the Phantoms shooting down 54 to 66 MiG-21s in return. In December 1966 the MiG-21 pilots of the 921st FR downed 14 F-105s without any losses. Its weaknesses include poor visibility and relatively short range, but has otherwise proven to be a capable fighter.

text: The US's Vought F-8 Crusader used in Vietnam weighed 8000 kg (17,500 lb), as compared with 13,750 kg (30,300 lbs) for an F-4 Phantom. It was a simple, supersonic, single engine, gun- and heat-seeker armed fighter in front-line service from 1957 to 1976. It had no radar except a simple ranging gunsite radar. The US claims the Crusader (up to 1968) shot down six enemy aircraft for every loss, compared with 2.4 for every Phantom lost. The three F-8s shot down in air-to-air were all lost to MiG-17 cannon fire.

text: The first few decades of the jet fighter era showed a combat history similar in general trend to that of the propeller fighters of World War II. So long as lighter fighters are of sufficient power-to-weight ratio and airframe sophistication, and flown by similarly skilled pilots, they tend to dominate over heavier fighters using surprise, numbers, and maneuverability. However, one significant difference did emerge in design strategy in the early jet fighter era. In World War II fighter design was strongly influenced by the seeking of higher speeds that were valuable in combat in order to close with the enemy or to escape. This trend was instinctively continued in some jet fighters through the 3rd generation (F-4 at Mach 2.23) and into the 4th generation (F-14 at Mach 2.35 and F-15 at Mach 2.5+). The aerodynamic requirements to operate at such speeds add considerable complexity, weight, and cost to the airframe. But, these Mach 2 and above class speeds have zero utility in combat. Combat speeds never exceed Mach 1.7 and seldom 1.2, for two reasons. First, it requires extensive use of the afterburner, which typically increases fuel consumption by about a factor of three or even four, and rapidly reduces operational radius. Second, speeds even above about Mach 0.7 to Mach 1 (depending on circumstances) so widen the turn radius in maneuvering combat that the fighter is thrown too wide to get a tracking solution on an opponent. Speed had reached the limit of its practical combat value, such that optimum fighter design required understanding the penalties the endless search for higher speed was imposing, and sometimes deliberately choosing not to accept those penalties.


title: Light fighter

text: As supersonic performance, with afterburning engines and modern missile armament, became the norm the Soviet Mikoyan MiG-21, the French Mirage III, and the Swedish Saab Draken entered service. The next generation of lightweight fighters included the American F-16 Fighting Falcon, Swedish JAS 39 Gripen, Indian HAL Tejas, Korean FA-50, Japanese Mitsubishi F-2, Chinese Chengdu J-10 and Pakistani CAC/PAC JF-17 Thunder. The high practical and budgetary effectiveness of modern light fighters for many missions is why the US Air Force adopted both the F-15 Eagle and F-16 in a "hi/lo" strategy of both an outstanding but expensive heavy fighter and a lower cost but also outstanding lightweight fighter. The investment to maintain a competitive modern lightweight fighter air force is approximately $90M to $130M (2013 dollars) per plane over a 20-year service life, which is approximately half the cost of heavy fighters so understanding fighter aircraft design trade-offs and combat effectiveness is of national level strategic importance.


title: Light fighter

text: In the 1960s and 1970s, a US-based "Fighter Mafia", led by colonels John Boyd , Everest "Rich" Riccione and analyst Pierre Sprey advocated for production of a 4th generation light fighter. Despite heavy fighter losses in the Vietnam War, most senior US Air Force leaders still opposed the light fighter concept. After much debate, General Dynamics designed the successful F-16. Its competitor, the Northrop YF-17, led to the successful McDonnell Douglas F/A-18 Hornet Navy fighter as a cheaper alternative to the F-14. The F-16 offered excellent air-to-air combat performance due partly to its fly-by-wire control system, which improved agility. When not burdened by heavy air-to-ground weapons, the F-16 had the longest range of any US fighter at the time. The F-16 and F/A-18 later added significant weight to become multirole fighters with strong air-to-ground capabilities, pushing them towards the "middleweight" range of modern fighters.


title: Light fighter

text: The Soviet counterpart to the F-16 and F/A-18, the Mikoyan MiG-29, was originally part of the "Perspektivnyy Lyogkiy Frontovoy Istrebitel" (LPFI, or "Advanced Lightweight Tactical Fighter") program.


title: Light fighter

text: In the 1980s the privately developed F-5G, later renamed the Northrop F-20 Tigershark, aimed to correct weaknesses in the aging F-5 while maintaining small size and low cost. Its empty weight was 6,000 kg (13,150 lbs). Its General Electric F404 engine produced 60 per cent more power than the F-5, and it had a higher climb rate and acceleration, better cockpit visibility, and more modern radar. Chuck Yeager, test pilot and the first man to break the sound barrier, referred to the F-20 as "the finest fighter" of the mid 1980s. Despite its high performance and cost effectiveness, the F-20 lost out for foreign sales against the similarly capable, more expensive F-16, which was being procured in large numbers by the US Air Force and was viewed as having greater support. The Tigershark was cancelled having made no sales.


title: Light fighter

text: The HAL Tejas has an empty weight of 6,500 kg (14,300 lbs), and is the lightest fighter among current production light fighters. Introduced into limited service in 2014, with 16 IOC specification aircraft delivered to January 2020, it was the lowest-cost fighter aircraft with competitive air-to-air capability in production at that time, at an equivalent cost of US$27 million. A further 16 fighter aircraft, in a FOC specification, and 8 dual seat trainer aircraft have been ordered, are expected to be delivered by the middle of 2021. The design is similar to the Mirage III and JAS 39 Gripen, being a light tailless delta-wing single-engine fighter with ground attack capability.


title: Light fighter

text: The French Dassault Mirage 2000 was designed for the French Air Force ("Armée de l'Air") in the late 1970s, as a lightweight single-engine fighter. Based on the Mirage III, it entered service in 1982, and has since evolved into a multirole aircraft. In heavier multirole form, it has empty weight of 7,400 kg (16,300 lb). More than 600 were built and it has served in the air forces of nine nations.


title: Light fighter

text: South Korea's KAI T-50 Golden Eagle, designed by Lockheed Martin with Korea Aerospace Industries, is based on the F-16 multirole-fighter. Its latest variant, the FA-50 Fighting Eagle, is designated as a light fighter and trainer. It uses the same air frame as the T-50 advanced trainer introduced in August 2002. It is now deployed with South Korean Air Force and the Philippine Air Force.


title: Light fighter

text: The CAC/PAC JF-17 Thunder light fighter was developed jointly by China's Chengdu Aircraft Corporation and Pakistan's Pakistan Aeronautical Complex in the early 2000s. it was inducted into the Pakistan Air Force in February 2010. At least 66 aircraft have been delivered to Pakistan. More aircraft are scheduled to be introduced in 2018. A twin-seater variant was undergoing flight testing as of late 2015.


title: Light fighter

text: The JAS 39 Gripen is a single-engine light fighter manufactured by the Swedish aerospace company Saab. With an empty weight of 6,800 kg (14,900 lbs) it is the second lightest fighter in production as of 2016. Though primarily an air superiority fighter, the design has effective air-to- ground capability as well. Its delta wing offers high cruise and super-cruise (above Mach 1 without using after-burner), low wing-loading and high maneuverability. It can operate from short airstrips and 800m (800 yard) sections of road, can be serviced by moderately trained mechanics, and has high sortie rates. Among Western 4th generation fighters the Gripen has the lowest operating cost at about $4,700 per flight hour (as of 2012). The lowest operating cost in current range of fighters discussed above is of HAL Tejas of about $4,000. Among western fighters, next best operating cost fighter is the F-16 at about $7,000 per flight hour. The Gripen has relaxed stability fly-by-wire flight controls for maximum agility, a top speed of Mach 2, a 27mm cannon, heat-seeking missiles, and radar-guided missiles.


title: Light fighter

text: The issue of where a fighter is best positioned on the weight, cost, and complexity curve is still a contentious issue. Stealth technology (airframe and engine design that strongly reduce radar and heat signatures) seeks to emphasize the most important feature of fighter effectiveness, the element of surprise. So far it has been featured only on heavier and more expensive fighters, specifically the F-22 Raptor and F-35 Lightning II. These fighters are not only stealthy, but also have information or combat awareness advantages due to active electronically scanned array (AESA) radars, and data linking for external cuing of enemy position and friendly force status. Their combination of near invisibility, superior combat awareness, networking, and reliable Beyond Visual Range (BVR) missiles, enables them to get deep inside the enemy's OODA loop and destroy enemy fighters before their pilots are even aware of the threat.


title: Light fighter

text: Fighter drones (see Unmanned combat aerial vehicle) are under development, driven by the same tactical and cost effectiveness principles of light fighters. Their perceived advantages include not only cost and numbers, but the fact that their software based "pilot" does not require years of training, is always at the same peak effectiveness for each aircraft (unlike the human pilot case where the top 5% of pilots have historically scored about 50% of all kills), is not physiologically limited, and does not have a life to lose if the aircraft is lost in combat. Though there is cultural resistance to replacement of human fighter pilots and also concerns about entrusting life and death decisions to robot software, such fighter drones are expected to eventually be implemented.


title: Chief warrant officer

text: Chief warrant officer is a military rank used by the United States Armed Forces, the Canadian Armed Forces, the Pakistan Air Force, the Israel Defense Forces, the South African National Defence Force, the Lebanese Armed Forces and, since 2012, the Singapore Armed Forces. In the United States Armed Forces, chief warrant officers are commissioned officers, not non-commissioned officers (NCOs) like in other NATO forces.


title: Chief warrant officer

text: In the Canadian Armed Forces, a chief warrant officer or CWO is the most senior non-commissioned member (NCM) rank for army and air force personnel. Its equivalent rank for navy personnel is chief petty officer 1st class (CPO1). The French language form of chief warrant officer is .


title: Chief warrant officer

text: A CWO is senior to the rank of master warrant officer (MWO) and its navy equivalent of chief petty officer 2nd class (CPO2).


title: Chief warrant officer

text: Cadets Canada uses the ranks of chief petty officer 1st class (Royal Canadian Sea Cadets), chief warrant officer (Royal Canadian Army Cadets), and warrant officer 1st class (Royal Canadian Air Cadets). This organization's uniforms use a similar coat of arms insignia as the Canadian Armed Forces.


title: Chief warrant officer

text: The rank insignia of the CWO is a simplified version of the 1957 coat of arms of Canada, worn on both forearms of the service dress tunic; in gold metal and green enamel miniature pins on the collar of the service dress shirt and outerwear coats (army only); on CADPAT ranks worn in the middle of the chest, embroidered in tan (army) or blue (air force) thread; and in pearl-grey thread on blue slip-ons on both shoulders of other uniforms (air force only).


title: Chief warrant officer

text: The insignia lacks the annulus, from 1985 changes, behind the shield bearing the motto of the Order of Canada. It also differs from both the 1957 and 1985 versions through a lack of compartment and mantling.


title: Chief warrant officer

text: CWOs are generally initially addressed as "Chief Warrant Officer", and thereafter as "Sir" or "Ma'am" by subordinates; and as Mr. or Ms. by commissioned officers. If they hold the appointment of regimental sergeant-major, they may also be addressed as "RSM" by the commanding officer, other officers, or when referred to in conversation. CWOs are never addressed as "Chief", this being a form of address reserved for chief petty officers. Civilians can address them as Chief Warrant Officer or CWO or Mr/Mrs/Miss/Ms (followed by surname).


title: Chief warrant officer

text: CWO/CPO1 may fulfill roles in a number of key positions (KP). These positions require the incumbent to act in an advisory or liaison role to a non-command position i.e. Assistant Judge Advocate General Liaison Chief Petty Officer, RCEME Corps Sergeant-Major, Defence Ethics Program Chief Warrant Officer.


title: Chief warrant officer

text: Due to the unified nature of the Canadian Armed Forces, it is not unheard-of for air force CWOs or even navy CPO1s especially those of the so-called "purple trades", such as logistics or military police to find themselves filling the appointment of RSM in what are otherwise considered Canadian Army units (such as service battalions or communication regiments). Conversely, it is not impossible for an army CWO or navy CPO1 to be the squadron CWO of a Royal Canadian Air Force squadron.


title: Chief warrant officer

text: Senior appointments for chief warrant officers and chief petty officers 1st class entitle the incumbents to wear a modified rank badge or an addition to the rank badge. They are as follows:


title: Chief warrant officer

text: The coat of arms over the central insignia of the badge of the Canadian Armed Forces (crossed swords, an anchor and an eagle in flight). This appointment is given to CWO assigned to commanders at the base, brigade, wing, and division levels. Specific examples include base chief warrant officer, brigade sergeants-major, wing chief warrant officers, the division chief warrant officer (DCWO) of 1 Canadian Air Division and the division sergeant-major (Div SM) of 3rd Canadian Division (3 Cdn Div). A formation chief warrant officer would typically be seen with a colonel or brigadier-general, but may occasionally be seen with a lieutenant-colonel or major-general.


title: Chief warrant officer

text: The coat of arms with a wreath of laurel wrapped around the base. This appointment is given to CWO/CPO1 assigned to commanders of commands including to the commander Canadian Special Operations Forces Command, commander Canadian Forces Intelligence Command and commander Canadian Joint Operations Command. The command chief warrant officer appointed to the commander Canadian Army is called the Canadian Army sergeant-major, while the command chief warrant officer appointed to commander RCAF is known as Chief Warrant Officer of the Air Force. The command chief warrant officer of the RCN is known as the RCN Command Chief Petty Officer. A command chief warrant officer/chief petty officer would be seen with a major-general/rear-admiral or lieutenant-general/vice-admiral.


title: Chief warrant officer

text: CWOs generally mess and billet with other warrant officers and with sergeants, and their navy equivalents, chief petty officers and petty officers. Their mess on military bases or installations are generally named the "Warrant Officers and Sergeants Mess".


title: Chief warrant officer

text: Although NCMs, CWOs generally wear the uniform accoutrements of commissioned officers; for example, officer cap badge, waistcoat instead of cummerbund with mess dress, etc.


title: Chief warrant officer

text: The רב-נגד Rav nagad, a "Chief Warrant Officer" is the most senior non-commissioned officers rank in the Israel Defense Forces (IDF). Because the IDF is an integrated force, they have a unique rank structure. IDF ranks are the same in all services (army, navy, air force, etc.). The ranks are derived from those of the paramilitary Haganah developed in the British Mandate of Palestine period to protect the Yishuv. This origin is reflected in the slightly-compacted IDF rank structure.


title: Chief warrant officer

text: In 2008 the Warrant Officer ranks of the South African National Defence Force were expanded and the rank of Chief Warrant Officer was created.


title: Chief warrant officer

text: In the South African Navy a Chief Warrant Officer is the senior NCO in Fleet Command. In the South African Army the equivalent is the senior NCO in an Army Formation, such as Armour, Infantry etc.


title: Chief warrant officer

text: Chief warrant officer in the United States Armed Forces refers to any warrant officer in pay grades CW2 and above. All warrant officers (WO1 to CWO5) are officers and rate a salute by all enlisted NATO other ranks personnel. The U.S. Army and the U.S. Marine Corps use WO1/WO through CW5/CWO5 as designators and the U.S. Navy uses WO1 for one specialty (cyber warfare); all other branches of the U.S. Armed Forces use CWO2 through CWO5. The U.S. Air Force, although authorized to appoint warrant officers, does not utilize those grades in any capacity. All warrant officers dine in the officers' mess but rate just below O-1 (NATO rank code OF-1).


title: Chief warrant officer

text: On 4 June 2018, the Chief of Naval Operations announced the reestablishment of the rank of warrant officer one (pay grade W-1), for cyber warrant officers, and solicited applications for the rank/grade. These warrant officers will receive their appointment via warrant and not via commission. They will incur a six-year service obligation once promoted to W-1. A minimum of three-years in grade with a total service time of 12 years must be achieved before appointment and commission to chief warrant officer (W-2). However, the President also may grant appointments of warrant officers in the grade of W-1 via commission at any time as well as the Secretary of the Navy may also appoint warrant officers in that grade via commission, through additional regulations. In mid-December 2018, the Navy announced that six selectees had been named. They will wear a distinctive cap badge with two crossed anchors.


title: Chief warrant officer

text: Warrant officer rank insignia is the only officers' insignia that is not the same for all branches of the U.S. military, with one exception. The rank insignia for a CW5 became the only universal insignia within the warrant officer ranks when the U.S. Navy promoted its first CWO5 in 2002 and the Army adopted the emblem in 2004.


title: Chief warrant officer

text: Warrant officers in the United States are classified as officers and are in the "W" category (NATO "WO"); they are technical leaders and specialists. Chief warrant officers are commissioned by the president of the United States and take the same oath as regular commissioned officers do. They may be technical experts with a long service as enlisted personnel or direct entrants, most notably as U.S. Army helicopter pilots.


title: Evergreen forest

text: An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, Live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones.


title: Evergreen forest

text: Coniferous temperate evergreen forests are most frequently dominated by species in the families. The trees include: Pinaceae and Cupressaceae. Broadleaf temperate evergreen forests include those in which Fagaceae, such as oaks and ferns are common, those in which Nothofagaceae predominate, and the eucalyptus forests of the Southern Hemisphere. There also are assorted temperate evergreen forests dominated by other families of trees, such as Lauraceae in laurel forest.


title: Evergreen forest

text: Temperate evergreen forests, coniferous, broadleaf, and mixed, are found largely in the temperate mid-latitudes of , Siberia, Canada, Australia, Africa, Scandinavia, Indonesia, Malaysia, Amazon and Orinoco basins of South America, Himalayas and western ghats of India and Andaman and the Nicobar Islands. Broadleaf evergreen forests occur in particular in southern China, southeastern Brazil, and parts of southeastern North America. and in countries around the Mediterranean Basin, such as Lebanon and Morocco. Other evergreen forests (or "tropical rainforests") are usually found in areas receiving more than 234 cm of rainfall and having a monthly mean temperature of 20 °C or higher in the coldest months. They occupy about seven percent of the Earth's surface and harbour more than half of the planet's terrestrial plants and animals. Tropical evergreen forests are dense, multi-layered, and harbour many types of plants and animals. These forests are found in the areas receiving heavy rainfall (more than 200  cm annual rainfall). They are very dense. Even the sunlight does not reach the ground. Numerous species of trees are found in these forests. In some regions, some types of trees shed their leaves at different times of the year. Therefore, these forests always appear green and are known as evergreen forest.


title: Agriculture in the United Kingdom

text: Agriculture in the United Kingdom uses 71% of the country's land area, employs 1% of its workforce (467,000 people) and contributes 0.5% of its gross value added (£11.2 billion). The UK currently produces about 60% of its domestic food consumption.


title: Agriculture in the United Kingdom

text: Agricultural activity occurs in most rural locations. It is concentrated in the drier east (for crops) and the wetter west (for livestock). There are 216,000 farm holdings, which vary widely in size.


title: Agriculture in the United Kingdom

text: Despite skilled farmers, advanced technology, fertile soil and subsidies, farm earnings are relatively low, mainly due to low prices at the farm gate. Low earnings, high land prices and a shortage of let farmland discourage young people from joining the industry. The average (median) age of the British farm holder is about 60 (as of 2016).


title: Agriculture in the United Kingdom

text: Recently there have been moves towards organic farming in an attempt to sustain profits, and many farmers supplement their income by diversifying activities away from pure agriculture. Biofuels present new opportunities for farmers against a background of rising fears about fossil fuel prices, energy security, and climate change. There is increasing awareness that farmers have an important role to play as custodians of the British countryside and wildlife.


title: Agriculture in the United Kingdom

text: The total area of agricultural holdings is about 23.07 million acres (9.34 million hectares), of which about a third are arable and most of the rest is grassland. During the growing season about half the arable area is cereal crops, and of the cereal crop area, more than 65% is wheat. There are about 31 million sheep, 10 million cattle, 9.6 million poultry and 4.5 million pigs. These are arranged on about 212,000 holdings, whose average cultivable area is around . About 70% of farms are owner-occupied or mostly so (perhaps with individual barns or fields let out), and the remainder are rented to tenant farmers. Farmers represent an ageing population, partly due to low earnings and barriers to entry, and it is increasingly hard to recruit young people into farming. The average farm holder is about 60 years old.


title: Agriculture in the United Kingdom

text: British farming is on the whole intensive and highly mechanised. This approach is well-suited to the current distribution infrastructure, but can be less productive by area than smaller scale, diversified farming. The UK produces only 59% of the food it consumes. The vast majority of imports and exports are with other Western European countries.


title: Agriculture in the United Kingdom

text: Farming is subsidised, with subsidies to farmers totalling more than £3 billion (after deduction of levies).


title: Agriculture in the United Kingdom

text: While there is little difference between farming practices in England, Scotland, Wales and Northern Ireland in places where the terrain is similar, the geography and the quality of the farmland does have an impact. In Wales, 80% of the farmland is designated as a "Less Favoured Area", and in Scotland the figure is 84%. "Less Favoured Area" means land that produces a lower agricultural yield, typically upland moors and hill farms, which explains the tendency to focus on sheep and sometimes dairy farming. In England, the eastern and southern areas where the fields are flatter, larger and more open tend to concentrate on cereal crops, while the hillier northern and western areas with smaller, more enclosed fields tend to concentrate on livestock farming.


title: Agriculture in the United Kingdom

text: Farming was introduced in the British Isles between about 5000 BC and 4500 BC after a large influx of Mesolithic people and following the end of the Pleistocene epoch. It took 2,000 years for the practice to extend across all of the isles. Wheat and barley were grown in small plots near the family home. Sheep, goats and cattle came in from mainland Europe, and pigs were domesticated from wild boar already living in forests. There is evidence of agricultural and hunter-gatherer groups meeting and trading with one another in the early part of the Neolithic.


title: Agriculture in the United Kingdom

text: The Saxons and the Vikings had open-field farming systems. Under the Normans and Plantagenets fens were drained, woods cleared and farmland expanded to feed a rising population, until the Black Death reached Britain in 1349. This and subsequent epidemics caused the population to fall; one-third of the population in England died between 1349 and 1350. In consequence, areas of farmland were abandoned. The feudal system began to break down as labourers, who were in short supply following the plague, demanded wages (instead of subsistence) and better conditions. Also, there were a series of poor harvests after about 1315, coinciding with some evidence (from tree rings) of poor weather across the whole of northern Europe, which continued on and off until about 1375. The population did not recover to 1300 levels for 200 to 300 years.


title: Agriculture in the United Kingdom

text: When King Henry VIII named himself Supreme Head of the Church of England in 1531, he set about the dissolution of the monasteries, which was largely complete by 1540. The monasteries had been among the principal landowners in the Kingdom and the Crown took over their land, amounting to about . This land was largely sold off to fund Henry's military ambitions in France and Scotland, and the main buyers were the aristocracy and landed gentry. Agriculture boomed as grain prices increased sixfold by 1650. Improvements in transport, particularly along rivers and coasts, brought beef and dairy products from the north of England to London.


title: Agriculture in the United Kingdom

text: Jethro Tull, a Berkshire farmer, invented his famous rotating-cylinder seed drill. His 1731 book, "The New Horse Hoeing Husbandry", explained the systems and devices he espoused to improve agriculture. The book had such an impact that its influence can still be seen in some aspects of modern farming. Charles Townsend, a viscount known as "Turnip Townsend", in the 1730s introduced turnip farming on a large scale. This created four-crop rotation (wheat, turnips, barley and clover) which allowed fertility to be maintained with much less fallow land. Clover increases mineral nitrogen in the soil and clover and turnips are good fodder crops for livestock, which in turn improve the soil by their manure.


title: Agriculture in the United Kingdom

text: Between 1750 and 1850, the English population nearly tripled, with an estimated increase from 5.7 million to 16.6 million, and all these people had to be fed from the domestic food supply. This was achieved through intensified agriculture and land reclamation from the Fens, woodlands, and upland pastures. The crop mix changed too, with wheat and rye replacing barley. Nitrogen fixing plants such as legumes led to sustainable increased yields. These increased yields, combined with improved farming machinery and then-new capitalist ways of organising labour, meant that increased crop production did not need much more manpower, which freed labour for non-agricultural work. Indeed, by 1850 Britain had the smallest proportion of its population engaged in farming of any country in the world, at 22%.


title: Agriculture in the United Kingdom

text: Farmers were one of the groups of society that contributed significantly to the numeracy revolution achieved in Europe during the early modern era. During the 18th century, a large share of farmers had the ability to basic numerical skills as well as the ability to read and write (literacy), both of which are skills that were far from widespread in the early modern period. This is unsurprising for countries such as England, where farmers developed particularly high human capital skills because of rapid occupational changes – they became a minority that produced the food for the majority of the population. One possible explanation for this phenomenon is the strong link between nutrition and cognitive abilities. A constant amount of nutrition was almost always available to farmer families, they could feed themselves even during times of famine by increasing the share of their products that they consumed themselves instead of selling them on markets.


title: Agriculture in the United Kingdom

text: Open fields divided among several tenants originally had the advantage of reducing risks by giving all farmers diverse soils and crops so no one faced famine when others prospered. But the system was inefficient. Poor farmers got as much land as good farmers. By the 18th century enclosures came in poorer regions where several landholders were more willing to sell land. After 1760, though, parliamentary legislation permitted the enclosure of wealthier lands that had more complex structures of ownership. The result was an added £4 million to England's national income.


title: Agriculture in the United Kingdom

text: During the 18th and 19th centuries, enclosures were by means of special acts of Parliament. They consolidated strips in the open fields into more cohesive units, and enclosed much of the remaining pasture commons or "wastes". Enclosure consisted of exchange in land, and an extinguishing of common rights. This allowed farmers to consolidate and fence off their own large plots of land, in contrast to multiple small strips spread out and separated. Voluntary enclosure was also frequent at that time.


title: Agriculture in the United Kingdom

text: At the time of the parliamentary enclosures, most manors had seen consolidation of tenant farms into multiple large landholdings. Multiple larger landholders already held the bulk of the land. They 'held' but did not legally own in today's sense. They also had to respect the open field system rights, when demanded, even when in practice the rights were not widely in use. Similarly each large landholding would consist of scattered patches, not consolidated farms. In many cases enclosures were largely an exchange and consolidation of land, and exchange not otherwise possible under the legal system. It did also involve the extinguishing of common rights. Without extinguishment, one man in an entire village could unilaterally impose the common field system, even if everyone else did not desire to continue the practice. "De jure" rights were not in accord with "de facto" practice. With land one held, one could not formally exchange the land, consolidate fields, or entirely exclude others. Parliamentary enclosure was seen as the most cost-effective method of creating a legally binding settlement. This is because of the costs (time, money, complexity) of using the common law and equity legal systems. Parliament required consent of the owners of 4/5-ths of the land (copy and freeholders).


title: Agriculture in the United Kingdom

text: The primary benefits to large land holders came from increased value of their own land, not from expropriation. Smaller holders could sell their land to larger ones for a higher price post enclosure. There was not much evidence that the common rights were particularly valuable. Protests against Parliamentary Enclosure continued, sometimes in Parliament itself, frequently in the villages affected, and sometimes as organised mass revolts. Voluntary enclosure was frequent at that time. Enclosed land was twice as valuable, a price which could be sustained only by its higher productivity.


title: Agriculture in the United Kingdom

text: This peaceful period included a twenty-year depression in agriculture 1815 to 1836. It was so severe that landlords as well as tenants suffered financial ruin, and large areas of farmland were entirely abandoned. The ancient landlord and tenant system was unsuited to new-style, capital-intensive farms, which caused concern in Parliament. Parliament began to improve the legislation, for example by distinguishing between farm improvements that the tenant should fund, and those the landlord should fund.

text: From 1836 until Parliament repealed the Corn Laws in 1846, agriculture flourished. The repeal of the Corn Laws steadied prices, though agriculture remained prosperous. At that time, Parliament was concerned with the issue of tenant right, i.e. the sum payable to an outgoing tenant for farm improvements that the tenant had funded and, if crops were in the ground when the tenant left, compensation for their value. This was down to local custom which might vary from place to place. In 1848 a parliamentary committee examined the possibility of a standardised system, but a Bill on the matter was not passed until 1875.

text: The American Civil War ended in 1865, and by 1875, with new steam-powered railways and ships, the United States was exporting a substantial excess of cereals. At the same time, Britain suffered a series of poor harvests. By 1891 reliable refrigeration technology brought cheap frozen meat from Australia, New Zealand and South America to the British market, and Parliament felt it had to intervene to support British farming. The Agricultural Holdings (England) Act 1875 revamped the law on tenant right such that tenants received consistent levels of compensation for the value of their improvements to the holding and any crops in the ground. It also gave tenants the right to remove fixtures they had provided, increased the period of a Notice to Quit from six months to twelve, and brought in an agricultural dispute resolution procedure.


title: Agriculture in the United Kingdom

text: Some Landlords reacted to the 1875 Act by refusing to let land on a tenancy, instead contracting out the labour to contract farmers. Parliament responded with the Agricultural Holdings (England) Act 1883, which prevented contracting out on terms less favourable than a normal tenancy. Subsequent Agricultural Holdings Acts in 1900 and 1906 further refined the dispute resolution procedure; required landlords to compensate tenants for their damaged crops if the damage was caused by game that the landlord did not allow tenants to kill; allowed tenants to choose for themselves what crops to grow, except in the last year of the tenancy; and prevented penal rents being charged except in special circumstances. The mass of legislation was consolidated in another Act of 1908. Further Agricultural Holdings Acts came into force in 1914, two in 1920, and a further consolidating Act in 1923.

text: Invented in around 1885, the digging plough is a plough with a wider share, which cuts a wider shallower furrow, after which the slice of soil is inverted by a short concave mould-board with a sharp turn. This has the effect of breaking up and pulverising the soil, leaving no visible furrow and facilitating the use of a seed drill for planting. Earlier ploughs were simply large hoes for stirring the soil, drawn by animals, that left furrows suitable for distribution of seed by hand.


title: Agriculture in the United Kingdom

text: The Board of Agriculture was established by Act of Parliament in 1889. Although rationing during the First World War was limited to the end of 1917 and 1918, a change of mood arose about food security, and the Ministry of Food was created in 1916. There was a national feeling that a man who had fought for his country should be entitled to retire to a smallholding on British land that would provide him with a livelihood. This led to various initiatives, collectively called Homes for Heroes. By 1926 agricultural law had become openly redistributive in favour of ex-servicemen. County Councils had compulsory purchase powers to requisition land they could let as smallholdings. Ex-servicemen were the preferred tenants. The tenant could then buy the land and could ask the Council to lend them money to fund the purchase as a mortgage. The Council could not refuse without the Minister of Agriculture's permission.


title: Agriculture in the United Kingdom

text: In 1919 the Board of Agriculture and the Ministry of Food were merged to form the Ministry of Agriculture and Fisheries, which later became the Ministry of Agriculture, Fisheries and Food (MAFF). MAFF was in turn the predecessor of DEFRA.


title: Agriculture in the United Kingdom

text: Before the Second World War started, Britain imported 55 million tons of food a year. By the end of 1939, this had dropped to 12 million, and food rationing was introduced at the start of 1940. It did not completely end until July 1954. The government tried to encourage people to grow their own food in victory gardens, and householders were encouraged to keep rabbits and chickens for the table. There were 1.5 million allotments by 1943. Potatoes became "the food of the war". Because so many men had been conscripted into the army, women were drafted in to work the land; they were called the Women's Land Army, or less formally, "land girls".


title: Agriculture in the United Kingdom

text: Famously, the Government responded to a temporary wartime oversupply of carrots by suggesting that the RAF's exceptional night-flying was due to eating carotene. The ruse worked: consumption of carrots increased sharply because people thought carrots might help them see in the blackout, thus taking the pressure off other food supplies. But with so much of the agricultural labour force fighting, pressure on food supplies worldwide increased throughout the war. The government estimated that in 1945 world meat consumption would exceed supply by 1.8 million tons and that only wheat would be "available in abundance". The Prime Minister suggested that if necessary, food supplies could take priority over supplies for the military, and considered the possibility of famine in the occupied territories after the war.


title: Agriculture in the United Kingdom

text: The Agriculture Act 1947 broadly revamped agricultural law. It was a reaction to the privations of the Second World War, and was aimed at food security, so as to reduce the risk of a hostile foreign power being able to starve the UK into submission. The Act guaranteed prices, markets and tenure, so that a farmer could be assured that his land would not be taken away and whatever he grew would be sold at a known price. Yet another consolidating Agricultural Holdings Act followed it in 1948. These Acts made it harder to evict tenant farmers. With the new security tenants enjoyed, a system of rent reviews was necessary to take account of land price inflation. There were many other changes in the law, and each of these Acts needed negotiations between the Ministry of Agriculture and the National Farmers Union (NFU) to fix the support price to be paid for each agricultural product. They were enacted in a series of Agriculture (Miscellaneous Provisions) Acts in 1949, 1954, 1963, 1968 and 1972.


title: Agriculture in the United Kingdom

text: The Agriculture (Miscellaneous Provisions) Act 1976 was another far-reaching revamp of the law. At the time it was passed, the Lib-Lab Pact of 1976 needed Plaid Cymru's support in Parliament, and the provisions of this Act were part of Plaid Cymru's price for their vote. This Act allowed for succession of agricultural tenancies, so on a farmer's death, a relative with relevant skills or experience and no holding of his own could inherit the tenancy. This was limited to two generations of tenant.


title: Agriculture in the United Kingdom

text: On government instructions, the Northfield Committee began to review the country's agricultural system in 1977. It did not report until July 1979, by which time Margaret Thatcher's administration held power. The report influenced ongoing discussions between the NFU and the Country Landowners Association (CLA), who were trying to reach an agreement on new Agricultural Holdings legislation that could be presented to Parliament as having industry-wide support. This was agreed in 1984, but the two sides had not been able to agree a fundamental change to the security of tenure legislation. It did change the succession rules for existing tenancies such that a farmer might pass on his tenancy on retirement as well as on death—but no new tenancies from 1984 were to include succession rights.


title: Agriculture in the United Kingdom

text: By this time the then-European Economic Community (now the European Community)'s Common Agricultural Policy and the value of the green pound was having a direct impact on farming. The Agriculture Act 1986 was concerned with the value of the milk quota attached to land, and particularly how it ought to be shared between landlord and tenant. Nowadays, milk quotas no longer exist, but other subsidies (largely rolled up into Single Payments) still must be divided between the parties.


title: Agriculture in the United Kingdom

text: The National Farmers Union (NFU) was begun by a group of nine Lincolnshire farmers and, as the "Lincolnshire Farmers Union", held its first meeting in 1904. By 1908 they were called the National Farmers Union and were meeting in London. During the Second World War, the NFU worked hand in glove with the Ministry of Agriculture to ensure food security. Rationing continued after the war and it is a measure of the NFU's influence at that time that the Agriculture Act 1947 committed the government to undertake a national review of the industry every year in consultation with the NFU.


title: Agriculture in the United Kingdom

text: The close relationship between the NFU and the MAFF continued until New Labour reformed the MAFF into Defra in 2001, and indeed the MAFF was sometimes (if unfairly) called the "NFU's political wing". Defra is seen as more independent, although the NFU does remain a powerful and effective lobbying body that wields considerable influence in proportion to the industry's economic value.


title: Agriculture in the United Kingdom

text: The Royal Agricultural University, which was the first agricultural college in the English-speaking world, opened as the Royal Agricultural College in 1845. It was granted its royal charter shortly after its founding. By the latter half of the nineteenth century, as farming grew more complex and methodical and as productivity increased, there was a dawning recognition that farmers needed agricultural education. Thanks to government financial support for agricultural education in the 1890s, the Royal Agricultural College was followed by Writtle College in 1893 and Harper Adams University College in 1901. Meanwhile, the West of Scotland Agricultural College formed in 1899, the East of Scotland Agricultural College in 1901, and the North of Scotland Agricultural College in 1904; these colleges amalgamated to form the Scottish Agricultural College in 1990. Professor John Wrightson opened his private Downton Agricultural College in 1880; it closed in 1906 as it was unable to compete with the publicly funded state colleges.


title: Agriculture in the United Kingdom

text: Total income from farming in the United Kingdom was £5.38 billion in 2014, representing about 0.7% of the British national value added in that year. This is a fall of 4.4% in real terms since 2014. Earnings were £30,900 per full-time person in 2011, which represented an increase of 24% from 2010 values in real terms. This was the best performance in UK agriculture since the 1990s. Agriculture employs 476,000 people, representing 1.5% of the workforce, down more than 32% since 1996. In terms of gross value added in 2009, 83% of the UK's agricultural income originated from England, 9% from Scotland, 4% from Northern Ireland and 3% from Wales.

text: Most farmers of beef cattle or sheep made another net loss in the year to April 2010. Production, veterinary, bedding, property, power and machinery costs all underwent double-digit rises in percentage terms, meaning that the losses in the year to April 2010 increased over last year's losses by over £30/animal. However, wheat exports were much stronger than the previous year.

text: The UK's egg-laying flock is in decline. It fell by 5.5% in one year from June 1999 to May 2000. In 1971, there were 125,258 farms with egg-laying hens and by 1999 this was down to 26,500.


title: Agriculture in the United Kingdom

text: When in the EU, UK farmers received more than £3 billion a year via the Single Farm Payment. This is roughly £28,300 per farm, although this includes around £3,000 of environmental subsidies, such as for planting woodland. Following Brexit a new subsidy scheme is being introduced with a proposed reduction in direct payments with an increase in payments tied to specific environmental or developmental criteria.


title: Agriculture in the United Kingdom

text: The agricultural area used is 23.07 million acres (9.34 million hectares), about 70% of the land area of England. 36% of the agricultural land is croppable (arable), or 25% of the total land area. Most of the rest is grassland, rough grazing, or woodland.


title: Agriculture in the United Kingdom

text: Soil is a complex mix of mineral and organic components, produced when rock is weathered and acted on by living organisms. Most British soils are 2% to 5% organic and 95% to 98% mineral, but soils such as peat may contain up to 50% organic matter. In the British Isles as far south as the Thames Valley, the soil has been heavily glaciated, which not only ground down the rock but redistributed the resulting matter. As a result, most British soils date from the last ice age and are comparatively young, but in level areas and particularly south of the Thames Valley, there are much older soils.


title: Agriculture in the United Kingdom

text: Many British soils are quite acidic, and a large proportion of British farm land needs repeated applications of alkalines (traditionally lime) to remain fertile. Nitrites are soluble, so rain rapidly carries them away. Acid rain increases soil acidity, but even normal rain tends to be slightly acid, increasing the natural acidity of British soil. Rainfall in Britain exceeds the rate of evaporation. This means that in freely drained areas, soil base material is washed away, which leads to a higher concentration of organic acids in the ground. This relatively high soil acidity is one of the factors that lead to liming. Lime tends to counteract soil acidity, and with fine particulate soils such as clays, also encourages the formation of a better soil crumb structure that will aerate and help with drainage. Its benefits have been known, if not scientifically understood, since Roman times.


title: Agriculture in the United Kingdom

text: Owing to high rainfall in the UK, less freely drained areas tend to become waterlogged. Wet land may be unable to bear a tractor's weight, and drainage makes soil lighter and more easily worked, improves crops' ability to absorb food because there is more root surface area, stimulates helpful micro-organisms and allows accumulated poisons to be carried away. In Britain field drains are traditionally open ditches, but increasingly, covered pipes have been used in more modern times. Earthworms are important for creating small drainage channels in the soil and helping to move soil particles.


title: Agriculture in the United Kingdom

text: No appreciable plant growth takes place at temperatures below 4 °C. The growth rate increases as temperature rises, up to a maximum limit which is of no relevance to the British Isles. Dark soils tend to absorb more heat, and are therefore preferred.


title: Agriculture in the United Kingdom

text: As crops grow, they absorb nutrients from the soil, so land fertility degrades over time. However, if organic matter poor in nitrogen but rich in carbohydrate is added to the soil, nitrogen is assimilated and fixed. Fertility increases while land is under grass, which helps to accumulate organic matter in the soil. These factors mean that soil is traditionally improved by means of liming, draining, and allowing to lie fallow. It is traditionally fertilised with manure, nitrogen, phosphates, and potash.


title: Agriculture in the United Kingdom

text: 170 million tonnes of animal excreta ("slurry") is produced annually in the UK. This slurry can pollute watercourses, draining them of oxygen, can contain pathogenic microorganisms such as salmonella, and creates an odour that causes complaints if stored near people. Pigs and poultry in particular, which tend to be produced intensively on large holdings with a relatively small land area per animal, create manure that tends to be processed. This is done either by removing the liquid component and transporting it away, or by composting it, or more recently, by anaerobic digestion to produce methane which is later converted to electricity.


title: Agriculture in the United Kingdom

text: Farmyard manure is among the best all-round soil fertilisers. Urine contains about half the nitrogen and most of the potash that an animal voids, but tends to drain away, making it both the richest and the most easily lost element of manure. Dung contains the other half of the nitrogen and most of the phosphoric acid and lime. With dung, much of the nitrogen is lost in storage or locked up in slowly released forms, so greater quantities are necessary compared to artificial fertilisers. Manure is most effective when ploughed into the fields while it is still fresh, but this is not practical while crops are growing and in practice, most manure is stored and then applied in winter, or else added in ridges for root crops.


title: Agriculture in the United Kingdom

text: Leguminous plants such as peas, beans or lucerne live in a symbiotic relationship with certain bacteria that produce nodules on their roots. The bacteria extract nitrogen from the air and convert it to nitrogenating compounds that benefit the legume. When the legume dies or is harvested, its rotting roots nitrogenate the soil. Nitrogen stimulates plant growth, but overapplication softens the plant tissues, makes them more vulnerable to pests and disease, and reduces resistance to frost. It may be added by nitrogen-fixing crops, but many farmers prefer artificial fertilisers, which are quicker. The negative side-effects of adding nitrogen are mitigated by phosphates.


title: Agriculture in the United Kingdom

text: Nitrogen from soil gets into the water, and can be hazardous to human health. EC Directive 80/778/EEC and 91/676/EEC both mention a ceiling acceptable level of nitrates of 50 mg/litre, which is also the level recommended by the World Health Organization. In several places in Britain, particularly in the midlands and the south-east, nitrate concentrations occasionally exceed this level and the government has brought in regulations to control nitrate levels in the water. The regulations governing designated Nitrate Vulnerable Zones (NVZ) aim to protect ground and surface water from contamination with nitrates and manure. Around 68% of English farmland, 14% of Scottish farmland and all of Welsh farmland is within a NVZ. The NVZ rules control at what time of year farmers may apply nitrogen or manure to the land and oblige them to keep strict records of nitrogen-containing substances used. They also regulate slurry and manure storage.


title: Agriculture in the United Kingdom

text: The Welsh Government introduced an all Wales NVZ in 2021. Previously, 2.4% of Wales' land was designated as a NVZ. Environmental and fishing groups welcomed the new rules. It will be rolled out, pending a review by the Senedd, over the next three years. The review came after major political backlash from opposition parties and farmers.


title: Agriculture in the United Kingdom

text: Phosphates are substances that contain phosphorus, which stimulates root development in young plants and is therefore particularly valuable for root crops. It also increases yields and speeds up plant growth generally. Phosphates are not easily lost from soil, but they mostly occur in very stable forms that are not liberated quickly enough by natural processes, so fertilisation is necessary. Traditionally, phosphate-bearing materials added to soil include bonemeal, powdered slag, and seaweed.


title: Agriculture in the United Kingdom

text: Potashes are substances that contain potassium which promotes disease resistance and helps to build starches and sugars. Plants tend to absorb potash during early stages of growth, and potash tends to reduce the problems caused by applying nitrogen. It also increases the weight of an individual cereal grain. Traditional potash sources included applying ash to the land and ploughing in crop residues after the harvest. Artificial potash fertilisers were not used until deposits of potash salts were discovered in Germany in 1861.


title: Agriculture in the United Kingdom

text: Arable farming is the production of crops. Crop growth is affected by light, soil, nutrients, water, air, and climate. Crops commonly grown in the United Kingdom include cereals, chiefly wheat, oats and barley; root vegetables, chiefly potatoes and sugar beet; pulse crops such as beans or peas; forage crops such as cabbages, vetches, rape and kale; fruit, particularly apples and pears; and hay for animal feed. From 1992 until 2004, or 2006 for organic farms, there were subsidies for not growing any crops at all. This was called set-aside and resulted from EEC farming policies. From 2007 onwards, set aside subsidies in the UK were withdrawn.


title: Agriculture in the United Kingdom

text: Seeds may be sown in spring, summer or autumn. Spring-sown crops are vulnerable to drought in May or June. Autumn sowing is usually restricted to frost-hardy types of bean, vetch, or cereal such as winter wheat. Traditional sowing techniques include broadcasting, dibbling, drilling, and ploughing in. Drilling is normally the most economical technique where conditions are dry enough.


title: Agriculture in the United Kingdom

text: Climate change will have positive impacts on crop production in Ireland. The combined effects of higher concentration, warmer spring/summer temperatures and lengthened growing season will all be beneficial to certain types of crop production, specifically grains and barley and detrimental to other crops, such as potatoes.


title: Agriculture in the United Kingdom

text: In 2009, of cereal crops were sown in the UK. There were of oil seed rape, of peas and beans, of potatoes, and of sugar beet. Winter crops tend to be planted around mid-September, and spring crops as soon as the soil is ready. Each year the country produces about 6.5 million tonnes of barley, of which 1.5 million are exported, 2 million used in brewing and distilling activities and the remainder fed to livestock. The country also produces 14 to 15 million tons of wheat each year, of which farmers kept 3.9 million tonnes as stock in February 2012. In 2008, 750,000 tonnes of oats were produced, in 2011–2012 613,000.


title: Agriculture in the United Kingdom

text: During 1999–2003 production of barley ranged from 6,128,000 to 7,456,000, wheat from 11,580,000 to 16,704,000 and oats from 491,000 to 753,000.


title: Agriculture in the United Kingdom

text: Consumption of oats by the human population compared with livestock is proportionally higher in the UK than in European countries, 455,000 tonnes as forecast by farm officials during 2012; with 163,000 tonnes fed to livestock during 2011–2012.


title: Agriculture in the United Kingdom

text: From 2002 to 2003, of the cereals grown, 31% of barley, 36% of oats and 34% of wheat were used for human consumption.


title: Agriculture in the United Kingdom

text: Ploughing is not always regarded as essential nowadays, but the plough can improve soil by inverting it to improve soil aeration and drainage, release nutrients through weathering, and expose harmful pests to predators. It is also an effective method of weed control. Ploughing depth in Britain varies between 5–6 inches in some limestone regions to up to 18 inches in deep stoneless silt land. Most British ploughs are designed to turn a furrow of up to about a foot deep, which is relatively shallow compared to some other countries, where furrows of up to 16 inches are common. Other machines used to prepare land include "cultivators" (to break up land too heavy for a normal plough), "harrows" (to level the surface of ploughed land), "rolls" or "rollers" (used for firming the soil), "sprayers" and "dusters" (used to spread herbicides, fungicides, insecticides and fertilisers).


title: Agriculture in the United Kingdom

text: Reaping is the process of harvesting a crop. Traditionally reaping was done with the scythe and reaping hook, but in Britain these have been entirely superseded by machinery. Combine harvesters, so called because they both harvest and thresh the crop, are common. Other machines used include mowers, reapers, binders, harvesters, pea cutters and flax pullers. Once reaped, some crops are brought directly to market. Others need to be threshed to separate the cash crop from the straw and chaff. Wheat, oats, barley, beans and some kinds of small seed (e.g. clover) typically need to be threshed.


title: Agriculture in the United Kingdom

text: Since the Second World War, scientific and technical progress and the removal of tenancy-based restrictions on choice of crop have given British arable farmers a great deal more freedom to plan cropping sequences. Strict crop rotation is no longer technically necessary or even financially desirable. Factors that influence crop sequences include the soil type, weather, the price and availability of labour and power, market outlets, and technical considerations about maintaining soil fertility and crop health. For example, some vigorous crops such as kale or arable silage will, when liberally fertilised, tend to outgrow and smother weeds. Many pests and diseases are crop-specific and the more often a particular crop is taken, the greater the buildup of pests and diseases that attack it. The farmer will therefore try to design a sequence to sustain high yields, permit adequate weed control, service market needs, and keep the soil free from diseases and pests.


title: Agriculture in the United Kingdom

text: As a direct result of climate change, harvesting is coming earlier in the year. The increased temperatures and levels allow this to happen. This means crops can be harvested well in advance of the heavy rain season.


title: Agriculture in the United Kingdom

text: Most diseases of crop plants result from fungus spores that may live in the soil and enter through roots, be airborne and enter the plant through damaged areas or landing on leaf surfaces, or are spread by pests. These spores tend to affect photosynthesis and reduce chlorophyll. They often make plants look yellow and affect growth and marketability of the crop. They are most commonly treated with fungicides, and may be called mildews, rusts, blotches, scabs, wilts, rots or blights. European Union regulations on pesticides are changing, and several important pesticides currently in use will no longer be available. This has potentially quite serious implications for British agriculture.


title: Agriculture in the United Kingdom

text: Climate change is bringing with it the earlier onset of winter rain. These very wet soils during spring time will also lead to unwanted pest and disease problems during the plating season.


title: Agriculture in the United Kingdom

text: Two of the most serious diseases currently affecting crop plants are colony collapse disorder (CCD), a somewhat mysterious effect that is wiping out honeybee colonies worldwide, and "varroa destructor", a parasitic mite that also affects honeybees and may be a contributor to CCD. Honeybees pollinate 80% of plants worldwide. In 2007, up to 80% of the bee colonies in some areas were wiped out. Honeybees pollinate crops worth about £200 million a year, and their total contribution to the economy may be as high as £1 billion.


title: Agriculture in the United Kingdom

text: Historically weed control was by hand-pulling of weeds, often during "fallowing" (which means leaving the land to carry no crop for a season, during which time the weeds can be found and removed). In 1896 it was found that a copper sulphate solution would kill broad-leaved weeds without seriously damaging young cereal plants. Other chemical weedkillers were soon discovered and now common chemical weedkiller ingredients include sodium chlorate, copper chloride, sulphuric acid, dinitroorthocresol and dinitrobutylphenol. Hormone-based weedkillers are used to kill weeds more selectively. Although most weeds are vulnerable to at least one of these substances, eradicating all the weeds from a particular area will usually need several different weedkillers. The use of pesticides has declined, and British farmers now use about a third less pesticides than they did in 1983. The crop needing most pesticides is wheat.


title: Agriculture in the United Kingdom

text: A pest is an animal that eats or spoils food meant for humans. Pests damage crops by removing leaf area, severing roots, or simply gross damage. In the UK, they comprise invertebrates (chiefly nematodes, slugs and insects or insect larvae), mammals (particularly rabbits) and birds (mainly members of the pigeon family). The damage caused by crop pests is considerable. For example, potato cyst nematodes cause over £50 million damage a year in the UK.


title: Agriculture in the United Kingdom

text: Pastoral farming is the breeding of livestock for meat, wool, eggs and milk, and historically (in the UK) for labour. Livestock products are the main element of the UK's agricultural output. The most common meat animals in the United Kingdom are cattle, pigs, sheep and poultry. Overwhelmingly, British wool comes from sheep, with only a few goats or alpacas bred for exotic wools such as cashmere or angora. The vast majority of milk comes from cattle, and eggs from chickens.
