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
