3. Soil Erosion

Soil erosion is a universal phenomena. It may be observed to some extent in all parts of the country, its intensity, however, is more in the arid, semi-arid, and mountainous areas. The presence of forests reduces the danger of soil erosion significantly. In recent years, the agricultural area has been expanded by indiscriminate felling of trees. The increase in the rate of soil erosion is not only damaging the agricultural lands, it is also affecting adversely tire areas where the eroded soil is deposited.

In order to minimise the danger of soil erosion, afforestation is imperative. Moreover, the farmers should apply more manures and develop wind breakers in the desert areas. Development of terraces in the hills, leveling of gullies, and contour ploughing in the hilly areas can also go a long way in reducing soil erosion.
