Detailed explanation-1: -The Sahel, the vast semi-arid region of Africa separating the Sahara Desert to the north and tropical savannas to the south, is as much a land of opportunities as it is of challenges.

Detailed explanation-2: -The Sahel climate is characterised by extreme temperatures with fluctuating periods of rainfall and intense drought. The area is particularly vulnerable to climate change, according to the United Nations, with temperatures increasing at 1.5 times the rate of the global average.

Detailed explanation-3: -In pure geographic terms the Sahel, or Sahil in Arabic, meaning coast or shore, is a vast region that stretches along the Sahara desert’s southern rim from the Atlantic to the Red Sea. Wedged between the desert to the north and tropical forests and savannah to the south, the belt has a tropical semi-arid climate.

Detailed explanation-4: -The semiarid steppes of the Sahel have natural pasture, with low-growing grass and tall, herbaceous perennials. Other forage for the region’s livestock (camel, pack ox, and grazing cattle and sheep) includes thorny shrubs and acacia and baobab trees.
