Tropical Africa: Food Production and theInquiry ModelHunger is the result of disasters such as drought, floods, the.changing of the jet stream patterns and other natural disasters.They are beyond our controlIt has been estimated that one third of the land in TropicalAfrica is potentially cultivable, though only about 6% of it is,currently cultivated. However, to change farming from a low-inputlow-yield pattern to a high-input, high-yield pattern necessitatesthe use of more fertilizer and the planting of high-yielding.varieties of cropsThere are a number of environmental factors, related mostly to.climate, soils and health, resisting easy developmental solutions.Rainfall reliability is closely connected to rainfall quantityThe rainfall in the equatorial heart is very plentiful andreliable. However, there is much less rainfall towards the outeredges of the rain belt. Periodic and unpredictable droughts are a.characteristic feature of these border zones:There are three climatic zones in Tropical Africa,1.a region of persistent rain at and near the Equator2.a region on each side of this of summer rain and winterdrought, and3.a region at the northern and southern edges afflicted by.droughtAll the climates listed in the previous paragraph are modifiedin the eastern parts of Tropical Africa by the mountains and.monsoonsThe soils of Tropical Africa pose another problem. They areunlike the soils of temperate areas. Soils are largely products oftheir climates, and tropical soils are different from temperatesoils because the climate is different. Because of the great heat,of the tropics tends to bake the soils, while on the other handthe rainfall leaches them. The combined heat and moisture tend toproduce very deep soils because the surface rock is rapidly brokendown by chemical weathering. All this causes the food's rate ofgrowth to slow down or maybe even stop and as a result foodproduction won't even come close in catching up to the rate of.population increase; therefore starvation and hunger is presentIn the process of a flood and drought, the roots of trees areshallow and virtually no nutrients are obtained from the soil. Thevegetation survives on its own humus waste, which is plentiful. Ifthe vegetation is cleared, then the source of humus is removed andthe natural infertility of the soils becomes obvious. As beinganother factor, this will cause the soil to produce wasteful and.useless products which in turn will decrease the productionTo conclude this essay, the climates in Tropical Africa takea big role as being factors that could endanger or destroy theprocess of plantation. On the other hand, it could also bring good.fortune if climatic regions are fairly good
