Question

which of the following practices could help reduce erosion of water banks?
a. buffer strips
b. natural fertilizers and pesticides
c. decrease in fossil fuel emissions
d. all of the above

Explanation:

Buffer strips are areas of vegetation (like grass or trees) near water banks. They act as a physical barrier. The roots of the plants in buffer strips hold the soil together. This prevents the soil from being washed away (eroded) by water. Natural fertilizers and pesticides mainly deal with soil fertility and pest control in agricultural settings, not directly with water - bank erosion. A decrease in fossil - fuel emissions is related to reducing air pollution and combating climate change (such as reducing acid rain which can have long - term impacts on water bodies, but not a direct measure for reducing water - bank erosion).

Answer:

A. buffer strips
