Farming in urban areas can boost food security

By Henry Neondo

The Food and Agriculture Organisation, FAO, has said that farming in urban areas could play an important role in feeding city populations.

In a press release on the eve of the World Environment Day, June 5, FAO, said that with the world's cities growing rapidly, farming in and around urban areas needs to play a bigger role in increasing urbanisation.

Urban and peri-urban farms already supply food to about 700 million city dwellers -- one-quarter of the world's urban population -- and nearly all of the world's population growth between now and 2030 will be concentrated in urban areas in developing countries, so that by then almost 60 per cent of people in developing countries will live in cities.

Urban agriculture involves using small plots such as vacant lots, gardens or roof tops in the city for growing crops and even for raising small livestock or milk cows.

It can take many forms, from small "micro-gardens" to larger operations.

A related practice is "peri-urban agriculture," consisting of farm units near cities that grow vegetables, raise chickens or livestock, and produce milk and eggs.

Urbanization poses challenges

Poverty rates in many cities are rising, and ever-larger numbers of city residents face difficulties accessing the food they need. In some developing countries, the urban poor spend 60 per cent or more of their income on food.

Problems are compounded by poor infrastructure for transporting food to urban centres. Long distances, bad roads, and urban crowding cause spoilage of 10 to 30 percent of produce in transit.

And as new, urban lifestyles lead greater numbers of people to consume more fats and less fibre, more fast food and fewer home-cooked meals, developing countries face a double challenge - widespread hunger on the one hand and rapid increases in obesity, diabetes, cardiovascular diseases and other diet-related diseases on the other.

One part of the solution: growing food in or near cities

Also, by increasing the diversity and quality of food consumed, it can significantly improve the quality of urban diets.

Sales of surplus produce, meanwhile, can generate income that can be used to buy more food. Even small "micro-gardens" can bring in up to $3 a day for poor families, according to FAO.

An estimated 1.2 billion people live on less than one dollar per day. Almost three billion make do on less than two dollars a day.

Success stories, obstacles

In the city of Dar es Salaam, Tanzania, 650 hectares are used for vegetable production, providing income to over 4 000 farmers.

One-metre-square rooftop tomato gardens introduced by an FAO project in Dakar, Senegal are yielding 18 to 30 kilos of tomatoes per year.

Yet despite their growing importance, urban and peri-urban agriculture are still subject to numerous constraints, such as lack of suitable land, uncertainty about land tenure, insufficient access to irrigation water of appropriate quality, inadequate know-how, and low investment.
