Desertification :: essays research papers

Es set up What is desertification, where is it found, and what are the causes?Desertification is the process by which land dries up eventually over time and the land turning to desert. This is common in Africa where closely of the terrain is a desert. It is believed that the Sahara desert was once fertile ground but now it is dried up. Sand as far as the eye can mark and very little rainfall occurs in this region.About 2500 B.C., the climate of the Sahara changed. Africa was once a fertile barren but where the Sahara lies was once a fertile plain capable of harvesting foods nearly anytime of year out-of-pocket to the warm weather. But it slowly dried up. As the land became parched, the desert spread. The process of desertification devours thousands of acres of cropland and eatage each year. As the region dried the people retreated. With no water and little food the land became inhabitable. Most people migrated south towards the marshlands and the savannah. It is believed on of t he causes of the Sahara is due to over harvesting of crops. It is believed that the Paleolithic people had learned how to cultivate in the Nile valley then spread out and established permanent villages. Archeologist say quite a few of the villages existed on the Sahara. Due to the farming over many years the land dried up due to the inadequacy of minerals and lack of water.The Bantu is what is believed to be the remnants of those who use to farm in the Sahara region. And archeologists have been able to track their migration by studying their language patterns. The Bantu were originally nomadic herders who travelled throughout Africa caring for their flock.
