Tropical Africa: Food Production and the Inquiry Model
Hunger is the result of disasters such as drought, floods, the
changing of the jet stream patterns and other natural disasters.
They are beyond our control.
It has been estimated that one third of the land in Tropical Africa is
potentially cultivable, though only about 6% of it is currently
cultivated. However, to change farming from a low-input, low-yield
pattern to a high-input, high-yield pattern necessitates the use of more
fertilizer and the planting of high-yielding varieties of crops.
There are a number of environmental factors, related mostly to
climate, soils and health, resisting easy developmental solutions.
Rainfall reliability is closely connected to rainfall quantity. The
rainfall in the equatorial heart is very plentiful and reliable. However,
there is much less rainfall towards the outer edges 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 Equator, 2. a region on each side of
this of summer rain and winter
drought, and 3. a region at the northern and southern edges
afflicted by
drought.
All the climates listed in the previous paragraph are modified
in the eastern parts of Tropical Africa by the mountains and monsoons.
The soils of Tropical Africa pose another problem. They are unlike
the soils of temperate areas. Soils are largely products of their
climates, and tropical soils are different from temperate soils
because the climate is different. Because of the great heat of the
tropics tends to bake the soils, while on the other hand, the rainfall
leaches them. The combined heat and moisture tend to produce very deep
soils because the surface rock is rapidly broken down by chemical
weathering. All this causes the food's rate of growth to slow down or
maybe even stop and as a result food production won't even come close in
catching up to the rate of population increase; therefore starvation and
hunger is present.
In the process of a flood and drought, the roots of trees are
shallow and virtually no nutrients are obtained from the soil. The
vegetation survives on its own humus waste, which is plentiful. If the
vegetation is cleared, then the source of humus is removed and the
natural infertility of the soils becomes obvious. As being another factor,
this will cause the soil to produce wasteful and useless products which
in turn will decrease the production.
To conclude this essay, the climates in Tropical Africa take a big
role as being factors that could endanger or destroy the process of
plantation. On the other hand, it could also bring good fortune if
climatic regions are fairly good.
