The present study evaluates the quality of the soil resource base of Africa and also the risks to sustainable agriculture and soil productivity on a continent-wide basis. Fifty five percent of the land in Africa is unsuitable for any kind of agriculture except nomadic grazing. These are largely the deserts, which includes salt flats, dune and rock lands, and the steep to very steep lands.

There are compelling reasons for African nations to return to fundamentals in terms of research and developmental initiatives. Those countries with subsistence agriculture have had minimal inputs in acquiring and managing information about their resource conditions.

The green revolution succeeded in Asia in those countries where there was a serious effort to match technology with resource conditions and where advances in development and use of high yielding cultivars was accompanied by appropriate soil, water, and nutrient management.

Sluggish or zero growth is likely because of the cumulative effect of many factors but with strong bearings on soil productivity. Agriculture production is not merely the managing of the biophysical resources; it is also strongly controlled by the socioeconomic milieu.

The opening of national markets to world trade has induced new stresses in the on-farm socioeconomic situation. The resource poor farmers of Africa have few options today to enhance their agricultural productivity.

Larson and Pierce view soil quality as the capacity of a soil to function within its ecosystem boundaries and interact positively with the environment external to that ecosystem. They link soil quality to the four sustainability objectives of Lourance -- agronomic, ecological, micro- and macro-economic sustainability.

A more formal definition, of Larson and Pierce and many others is, " the capacity of the soil, as an integral part of the ecosystem to perform the functions of: USDA Natural Resources Conservation Service NRCS is utilizing an "Ecosystems Based Approach" for its technology development and transfer program with soil quality being one of the basic criteria for the many decisions that have to be made with respect to sustainable land management.

From the point of land use and land management decision making, soil quality provides a quantitative basis for evaluating different land use options and impacts of technology; furnishes parameters for quantifying ecosystem interactions; evaluates status and impacts of soil conditions over given periods of time; provides a basis for targeting conservation programs; enables environmental assessment, or specific assessments related to biodiversity, chemical loads, bio-contaminants, etc.Essay about red soil in africa.
