Question

select the correct answer.
which of the following choices is an effective way to fight desertification?
a. irrigation
b. urbanization
c. soil erosion
d. tree plantings

Explanation:

Desertification is land degradation in arid, semi - arid, and dry sub - humid areas. Tree plantings (afforestation/reforestation) can help prevent soil erosion, improve soil quality, and increase vegetation cover, which are key to fighting desertification. Irrigation alone may not be effective if not managed properly and can even cause salinization. Urbanization often contributes to land degradation and is not a solution for desertification. Soil erosion is a result of desertification, not a solution.

Answer:

D. tree plantings
