desertification in the Sahel

Extracts from this document...


Desertification in the Sahel The Sahel is located in Central Africa. It is a narrow strip of land in the Southern region of the Sahara Desert. There are several countries which lie in the Sahel. Some countries which lie there suffer from severe desertification, like Niger, Chad, Sudan, Ethiopia, and Somalia. Desertification is turning land in arid and dry sub-humid areas, from human activities and climate change. This happens mainly in happens in poor countries with little rainfall. Desertification happens because of both physical and human factors. One of the main causes of desertification is climate change. Climate change causes less rain which means that vegetation dies so there is bare soil, thus desertification. There is a lack of rain in the Sahel because of the dry winds. ...read more.


It reduces the usefulness of the land. People let the animals graze in one place and then go on to another place where it is fresh to graze. This scars the landscape and leaves bare soil. Overgrazing happens in poorer countries where population is high and that there is an increase demand for food. Also high population leads to deforestation since people need the wood for shelter and cooking. There is a constant demand for wood so that means people travel from place to place in search of large areas of trees. Trees reduce soil erosion since trees block wind and take in water, which prevents it from loosening the soil. ...read more.


People have been forced to move to areas to grow vegetation. There are now little villages as they cannot live in the traditional ways of hunting animals and growing crops, but move to the big cities and work. Also there are less daily showers and sometimes no rain falls at all during the year. Desertification can be stopped and possibly reversed if good management of land is taken. Planting more trees and hedges to stop wind blowing away the soil helps as this stops soil erosion. Also the trees can be used to replace the ones chopped down. Also less intensive use of land means that that land can let to recover over a few years before using it again will also stop desertification. Fertilisers can be used so that the soil is more fertile so that desertification will not spread. ...read more.
