Detailed explanation-1: -Farming is difficult in the Sahel because there is very little water. Rainfall is scarce and there are no major rivers. For this reason, the Sahel is sparsely populated. There are also fewer plants and animals than in the regions of Africa farther south.
Detailed explanation-2: -Scant and unreliable rainfall and poor soils make the land difficult to farm, so for centuries, many people have raised livestock instead, moving their herds periodically to find fresh pastures and allow the land to recover.
Detailed explanation-3: -Under the combined effect of drought and floods, land is deteriorating and losing its fertility. Insufficient rain-fed irrigation means that crops fail or are destroyed, while livestock struggle to find water for drinking and sufficient pasture.
Detailed explanation-4: -The Sahel region of Africa is facing unprecedented humanitarian needs as a result of armed conflict, poverty, climate change, food insecurity and political instability.
Detailed explanation-5: -It stretches across the African continent from the Atlantic Ocean eastward to the Red Sea. Rainfall-or more specifically, the absence of significant rainfall-is a significant challenge for farmers in the Sahel. Droughts periodically cause severely reduced crop yields.
