Impact Of Rural Land Degradation in Semi-Arid Areas Flashcards
Environment
Crops have failed and livestock have become weak or died
Over cropping has exhausted nutrient levels in poor quality soils leading to soils that cannot support further crop harvests
Soils are left exposed to wind erosion
Heavy infrequent rain storms can wash away soil which turns semi-arid areas to desert eg Large areas of the Sahel
