Question 1 Report
Which of the following practices leads to land degradation in the savanna zones of West Africa? l. Constant annual bushfire ll. Overgrazing of grassland lll. Application of cattle manure. IV. Cutting of woody species for fuel wood
Answer Details
The practice that leads to land degradation in the savanna zones of West Africa is overgrazing of grassland, cutting of woody species for fuelwood, and constant annual bushfires. Overgrazing leads to the removal of vegetation cover, exposing the soil to erosion. Cutting of woody species for fuelwood reduces vegetation cover, which leads to soil erosion. Constant annual bushfires destroy vegetation cover and cause soil erosion. The application of cattle manure, on the other hand, helps to improve soil fertility, which is beneficial for agriculture. Therefore, the correct answer is option B: l, ll, and lV only.
