What is the type of subsistence farming found along sahel and east Africa due to what?

Reasons:

- Climate: The Sahel and East Africa are characterized by a semi-arid climate, with erratic rainfall and frequent droughts. This makes it difficult to rely on rain-fed agriculture, as crops are often damaged or destroyed by the harsh conditions.

- Land: The land in these regions is often poor quality, with thin soils and low fertility. This makes it difficult to grow crops, and even when crops can be grown, yields are often low.

- Population density: The population density in these regions is low, meaning that there is a large amount of land available for grazing. This allows pastoral nomads to move their herds to new areas when grazing becomes scarce.

Pastoral nomadism is a type of subsistence farming that involves the herding of livestock, such as cattle, sheep, and goats. Pastoral nomads move from place to place in search of water and pasture for their animals. They often live in tents or other temporary shelters, and they may travel hundreds of miles each year.

Pastoral nomadism is a way of life that has been practiced in the Sahel and East Africa for centuries. It is a sustainable form of agriculture that is well-adapted to the harsh climate and environment of these regions.
