Tropical Africa: Food Production And The Inquiry Model :: essays research papers

Tropical Africa Food Production and the Inquiry gravelHunger is the result of disasters such as drought, floods, the changing of thejet pelt recipes and other natural disasters. They ar beyond our control.It has been estimated that one third of the primer in Tropical Africa ispotentially 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 ofhigh-yielding varieties of cropsThere argon a number of environmental factors, related mostly to climate, soilsand health, resisting easy developmental solutions. rainwater reliability isclosely connected to rainfall quantity The rainfall in the equatorial heart isvery plentiful and reliable. However, there is much less(prenominal) rainfall towards theouter edges of the rain belt. Periodic and unpredictable droughts are acharacteristic feature of these border zones.There are thr ee climatical zones in Tropical Africa 1.a region of persistent rainat and approximately the Equator 2.a region on each side of this of summer rain and pass drought, and 3.a region at the northern and southern edges afflicted bydrought. solely the climates listed in the previous paragraph are modified in the easterlyparts of Tropical Africa by the mountains and monsoons.The soils of Tropical Africa pose another problem. They are unlike the soils oftemperate areas. Soils are largely products of their climates, and tropicalsoils are varied from temperate soils because the climate is different.Because of the great heat of the tropics slants to bake the soils, composition on theother hand, the rainfall leaches them. The combined heat and moisture tend toproduce very deep soils because the surface rock is rapidly confused d give bychemical weathering. All this causes the foods rate of growth to thick down ormaybe even stop and as a result food production wont even come close incat ching up to the rate of population increase therefore famishment and hungeris present. In the process of a flood and drought, the roots of trees areshallow and virtually no nutrients are obtained from the soil. The vegetationsurvives on its own humus waste, which is plentiful.
