Possible solution to the problem of soil erosion in the highlands of West Africa include all the following except
Answer Details
Soil erosion is a major problem in the highlands of West Africa due to factors such as deforestation, overgrazing, and unsuitable agricultural practices. The options listed in the question provide possible solutions to the problem of soil erosion except for one.
Option A, "indiscriminate felling of trees," involves cutting down trees without considering their impact on soil conservation. This practice increases the rate of soil erosion and is, therefore, not a solution to the problem.
Option B, "rotational grazing," involves dividing a large pasture into smaller areas and rotating the grazing of livestock between these areas. This helps to prevent overgrazing, reduces soil compaction, and allows grass to grow back.
Option C, "strip cultivation," involves planting crops in strips or rows and leaving spaces between them. This method reduces soil erosion by allowing rainfall to infiltrate the soil instead of running off.
Option D, "planting of shelter belts," involves planting trees or shrubs around farmlands to provide protection against wind and water erosion. This helps to stabilize the soil, reduce runoff, and provide habitat for wildlife.
Therefore, the answer is option A, "indiscriminate felling of trees," as it exacerbates soil erosion rather than solving it.
