What are the causes of land …

Causes of land degradation:

• Deforestation: Forests play an important role in maintaining fertility of soil by shedding their leaves which contain many nutrients. Forests are also helpful in binding up of soil particles with the help of roots of vegetation. Therefore, cutting о forests will affect the soil adversely.
• Excessive Use of Fertilizers and Pesticides-Excessive use of fertilizers is causing an imbalance in the quantity of certain nutrients in the soil. This imbalance adversely affects the vegetation.
• Overgrazing-Due to this, grass and other types of vegetation are unable to survive and grow in the area, and lack of vegetation cover leads to soil erosion. 
• Salination--Increase in the concentration of soluble salts in the soil is called salination. India has about six million hectares of saline land.
• Water-logging-Excessive irrigation and improper drainage facility in the fields cause rise in the ground water level. This ground water mixes with surface water used for irrigation and creates a situation called water-logging
• Desertification: Desertification is a widespread process of land degradation in arid, semi- arid, and dry sub-humid areas resulting from various factors, including climatic variations and human activities.
• Soil erosion:Accelerated soil erosion by water and wind is the major land degradation process and this is a consequence of changed relationship between environmental factors which occur as a result of human interventions.
• Wasteland-Wastelands are the lands which are economically unproductive, ecologically unsuitable and subject to environmental deterioration.

Ways to solve the problem of land degradation:

1. Gardening. Planting vegetation and grass can stop heavy rains from damaging our land and it protects the topsoil from being washed away.
2. Afforestation and Reforestation.
3. Conservation Tillage.
4. Constructing Wind Breakers.
5. Using Fertilizers.
