Use a flow chart to trace the main events that followed the development of agriculture on the african savannas.

The basis of the African economy is agriculture. It is, in general, an archaic agriculture that uses different techniques depending on environmental differences. It is conditioned by the lack of water and machinery. In the north, farmers use outdated and rudimentary formulas, while those in the Nile Valley obtain great yields from their traditional techniques, but using a great effort of men and animals.

In the attached file is the flow chart.

Explanation:

In a large part of Africa, agriculture is extremely rudimentary, where fertilizer, plowing and any natural crop selection are unknown. There are also some sedentary crops with sticks or the like. It is a subsistence agriculture that does not produce surpluses.  

Main crops:  

-Sorgo: Native to the tropical and subtropical regions of East Africa. It is an important resource of arid regions due to its resistance to drought and heat. Some wild species were used for food for millennia, both in Africa and in the Indian region.  

-Coffee, cocoa, sugarcane, or cotton  

The old colonial plantations remain with problems such as overproduction and excessive dependence on the evolution of prices. The production is entirely destined for export, through large multinational companies, so plantations tend to be close to communication channels.  

In the savannas of the North and the South, where the rainy months are less than five, and in the eastern highlands, agriculture has little development, so that there is a greater dedication to livestock. The animals are zebu and other bovids. This livestock has poor yields, and there are neither compound feed nor breed selection. Only in South Africa, Zimbabwe and Madagascar, a cattle ranch of good yields develops, it is bovine and rams that provide meat, skin and wool in abundance.
