What is left of the 75 percent of the earth’s surface made up of water is land. And land comprises rock and soil. Soil or what is left of the rocky part of land is what sustains life in the world. The ecosystem of the earth depends on soil and the bulk of the world’s food sourced from plants is produced from soil. Animal-based food sources, cattle, poultry, etc. also depend on soil for their sustenance. Cattle and other livestock depend on grazing for food, and poultry depend mostly on plant-based food too.
Soil erosion, contamination and salinization happen to hamper the continued fertility of arable land or food producing land for the world’s ten billion people. Soil erosion like contamination and salinization is mostly the resultant effects of human abuse of land. Contamination and salinization occur with the introduction of material that may be toxic or destructive of the fertility of land. Activity such as oil drilling and mining is some of the principal culprits in contamination and salinization. But several other factors including poor disposal management of certain material, such as used gas and diesel oil, plastics and industrial water material constitute the bulk of urban soil contamination and salinization.
Contaminants such as plastics may not dissolve easily in the soil and therefore make soil conservation difficult to achieve. However, conservation is the only means that assures the rejuvenation of the ecosystem, re-fertilizes the land and makes land most productive for human existence. What efforts are being made on the grown to prevent soil erosion, contamination and salinization in Africa?
