Desertification  Desertification is caused by a combination of factors that change over time and vary by location. These include indirect factors such as population pressure, socioeconomic and policy factors, and international trade as well as direct factors such as land use patterns and practices and climate-related processes. .Desertification is caused by a combination of factors that change over time and vary by location.

Desertification Present-day Drylands. Desertification refers to the persistent degradation of dryland ecosystems by climatic variations and human activities. It occurs on all continents (except Antarctica) and affects the livelihoods of millions of people, including a large proportion of the poor in drylands.

- Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.esertification has played a significant role in human history, contributing to the collapse of several large empires, such as Carthage, Greece, and the Roman Empire, as well as causing displacement of local populations.

Ghost Mine Episode 3 How Deserts are Formed. Deserts are formed when rain clouds run into wind or mountains and drop rain in one area, leaving the land further away dry. Deserts that form near bodies of water are usually caused by winds. For example, the Sahara desert, near the Mediterranean. Deserts near mountains are formed when rain clouds drop their rain on one side, and the land on the other side of the mountains stays dry.

Desertification: land degradation under a changing climate With these processes combined, around 12 million hectares of productive land become barren every year due to desertification and drought alone (UNCCD, 2014). Which regions are affected? Desertification is a major problem across the world, most notably in dryland areas (including large areas in Africa, such as the Sahel. About 40% of Earth’s land is covered by drylands, and these areas are home to over 2 billion people.

Causes and Effects of Desertification We Should Be Concerned About Due to the absence of vegetation on the land, there is no moisture in the soil to evaporate and form clouds that cause rainfall. Furthermore, less or no rainfall adds to the drought conditions, and the climate turns hotter and drier, causing more and more desertification.

Why is the Namib Desert so dry? The reason why deserts get so dry is because it is a dry place and when it rains it skips the desert. The desert is dry because, the precipitation (rain,snow,hail etc.) falls … in higher mountains/areas therefore when the air descends again it is dry. 3 people found this useful.

- Many things can cause desertification including human factors like overgrazing or other land use that leads to soil erosion or natural factors like a shift in rainfall. Desertification can be identified in satellite images by comparing rainfall to vegetation growth. If plants grow after rain falls, then the land is still productive and desertification has not happened. If plants fail to grow after rain, then the land might have become non-productive.

Acid Rain Causes of Acid Rain.

- night. As a result, deserts have large variations in daily high and low temperatures. How deserts form You may wonder why there is so little rain in the desert. The answer depends on which desert you are talking about. The Sahara and Australian deserts are caused by regions of high atmospheric pressure found near 30° latitude lines (Figure 16.6).

- Dehydration and/or starvation    Another Answer:   The most common cause of death in deserts is by drowning. More  people drown in the desert every year than by an…y other cause.  Flash floods can quickly develop after sudden thunderstorms and can  rapidly fill arroyos and streams to overflowing. People have little  to no warning and can be quickly swept away and drowned by these  sudden floods.

The Sahel: a report on desertification Desertification in the Sahel is progressing at an alarmingly rapid rate, with 2,500 hectares, an area the size of Luxemburg, being desertified each year. Desertification is the process by which land is turned from semi-arid scrubland to desert. This is caused by a myriad of reasons, both human and environmental.

Desertification: an ecological reality or a dangerous myth? It is quite a shock, then, to be presented with an abundance of evidence that desertification doesn’t happen, at least not in the way it has been explained. Scientifically, it is a meaningless and indefinable concept. The so-called desertification of the Sahel that created the scare happened for quite other reasons, and wasn’t irreversible. What’s more, the standard policies to reverse desertification generally do more harm than good, both to the environment and to people. This is the thesis of a new book by 20 experts in the field.
