Geography

The Sahel is primarily savannah and runs from the Atlantic Ocean to the Horn of Africa, changing from semi-arid grasslands to thorn savanna.

Environment

About 12,500 years ago, the Sahel was a part of the Saharan desert, and was covered in sand dunes which have shaped the landscape that we see today. The Sahel receives 150–500 mm (6–20 in) of rainfall a year, primarily in the monsoon season. The rainfall is characterized by great variation from year to year and from decade to decade. The most important limitations to land productivity in the Sahel are water and soil fertility. Soils in the Sahel are mostly acidic (which results in aluminum toxicity to plants), and are very low in nitrogen and phosphate.

Transhumance

Traditionally, most of the people in the Sahel have been semi-nomads, farming and raising cattle in a system of transhumance, which is probably the most sustainable way of utilizing the Sahel. The difference between the dry north with higher levels of soil-nutrients and the wetter south is utilized so that the herds graze on high quality feed in the North during the wet season, and trek several hundred kilometers down to the south, to graze on more abundant, but less nutritious feed during the dry period. Increased permanent settlement and pastoralism in fertile areas has been the source of conflicts with traditional nomadic herders. Kazakh nomads in the steppes of the Russian Empire, ca. ... Transhumance is the seasonal movement of livestock between mountainous and lowland pastures. ...


Droughts

Further information: Sahel drought

There was a major drought in the Sahel in 1914, caused by annual rains far below average, that caused a large-scale famine. The 1960's saw a large increase in rainfall in the region, making the Northern drier region more accessible. There was a push, supported by governments, for people to move northwards, and as the long drought-period from 1968 through 1974 kicked in, the grazing quickly became unsustainable, and large-scale denuding of the terrain followed. Like the drought in 1914, this led to a large-scale famine, but this time it was somewhat tempered by international visibility and an outpouring of aid. This catastrophe led to the founding of the International Fund for Agricultural Development. The Sahel drought in 1970s and 1980s created a famine that killed a million people and afflicted more than 50 million. ...
