Unsustainable farming methods, however, are negatively affecting both the environment and the livelihoods of the farmers who use them. Among these agricultural practices that are not sustainable are: Deforestation: Ghana's trees are being cut down for agriculture, leaving the ground naked and causing erosion and a decline in biodiversity. [32]
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination
Significant diamond deposits are found in river gravels in the central and eastern part of Ghana, although the country does not have kimberlite pipes where diamonds formed in the geologic past. Awaso, in southwest Ghana hosts a bauxite mine run by the Ghana Bauxite Company. The bauxite formed from the weathering of Paleoproterozoic phyllite.
Saprolite is a particular example of a residual soil formed from the transformation of granite, metamorphic and other types of bedrock into clay minerals. Often called weathered granite, saprolite is the result of weathering processes that include: hydrolysis, chelation from organic compounds, hydration and physical processes that include ...
The soil surrounding the lake is less fertile than the soil under it, and heavy agricultural use has required the use of fertilizers, which in turn has led to eutrophication, which caused, among others, the explosive growth of an invasive weed that renders water navigation and transportation difficult, and form a habitat for the vectors of ...
Geoconservation is the practice of recognising, protecting and managing sites and landscapes which have value for their geology or geomorphology. [1] [2] The conservation of these geological sites is through government agencies and local geological societies in areas such as Europe and Africa.
The Soil Conservation Service worked with state governments and universities with established agriculture programs, such as the University of Nebraska, to promote the method to farmers. By 1938, the introduction of new agricultural techniques, such as contour plowing, had reduced soil loss by 65% despite the continuation of the drought.
