Correct Answer: Tree plantation/afforestation
Solution : The correct answer is Tree plantation and afforestation .
In the desert region, soil erosion can be checked by afforestation, as plants and trees prevent the upper layer of soil from running off by the action of wind. It holds the particles of soil together and reduces the wind speed, thereby reducing soil erosion. Other ways are mulching, shelter belt creation through fibre logs, etc.
