Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
The Sahel zone lies between the Sahara desert and the fertile land of northern Nigeria and southern Sudan. Unfortunately, over the last century the Sahara desert has steadily crept southwards eating into once productive Sehel lands. United Nations surveys show that over 70 percent of the dry land in agricultural use in Africa has deteriorated over the last 30 years. Droughts have become more prolonged and more severe, the most recent lasting over twenty years in parts of the Sahel region. The same process of desertification is taking place across southern Africa as the Kalahari desert advances into Botswana.
One of the major causes of this desert advance is poor agricultural land use, driven by the pressures of increasing population. Overgrazing-keeping too many farm animals on the land - means that grasses and other plants cannot recover, and scarce water supplies are exhausted. Overcultivation — trying to grow too many crops on poor land — results in the soil becoming even less fertile and drier, and beginning to break up. Soil erosion follows, and the land turns into desert. Another reason of desertification is loss of tree cover. Trees are cut down for use as fuel and to clear land for agricultural use. Tree roots help to bind the soil together, to conserve moisture, and to provide a habitat for other plants and animals. When trees are cut down, the soil begins to dry and loosen, wind and rain erosion increase, other plant specifies die, and eventually the fertile topsoil may be almost entirely lost, leaving only bare rock and dust.
The effects of loss of topsoil and increased drought are irreversible. They are, however, preventable. Careful conservation of tree cover and sustainable agricultural land use have been shown to halt deterioration of soils and jen the effects of shortage of rainfall. One project in Kita in sout ali funded by the UNDP has involved local communities in sustainable management of forest, while at the same time providing a viable agricultural economy based on the production of soaps, bee-keeping, and marketing nuts. This may be a model for similar project in other West African countries.
