Explanation:
Desertification is defined as a process of land degradation in arid, semi-arid and sub-humid areas due to various factors including climatic variations and human activities. Or, to put it in another way, desertification results in persistent degradation of dry land and fragile ecosystems due to man-made activities and variations in climate.
Desertification, in short, is when land that was of another type of biome turns into a desert biome because of changes of all sorts. A huge issue that many countries have is the fact that there are large pockets of land that are going through a process that is known as desertification.
Overgrazing is the major cause of desertification worldwide. Other factors that cause desertification include urbanization, climate change, overuse of groundwater, deforestation, natural disasters, and tillage practices in agriculture that make soils more vulnerable to wind.
Desertification affects topsoil, groundwater reserves, surface runoff, human, animal, and plant populations. Water scarcity in drylands limits the production of wood, crops, forage, and other services that ecosystems provide to our community.
Control of Desertification:
1. Afforestation and planting of soil binding grasses can check soil erosion, floods and water logging.
2. Crop rotation and mixed cropping improve the fertility of the soil. ...
3. Desertification can be checked by artificial bunds or covering the area with proper type of vegetation.
