What are the causes of soil erosion and what methods can be used for soil conservation?
Understand the Problem
The text discusses soil erosion and soil conservation methods, particularly in the context of the Himalayan region. It addresses the causes of soil erosion and various techniques used to prevent it, such as contour ploughing and the establishment of shelter belts.
Answer
Causes: wind, water, deforestation. Conservation: contour ploughing, terracing.
The main causes of soil erosion are natural forces such as wind and water, along with human activities like deforestation and overgrazing. Soil conservation methods include contour ploughing, terracing, and planting shelter belts to prevent erosion.
Answer for screen readers
The main causes of soil erosion are natural forces such as wind and water, along with human activities like deforestation and overgrazing. Soil conservation methods include contour ploughing, terracing, and planting shelter belts to prevent erosion.
More Information
Contour ploughing involves ploughing along the contour lines of the land, reducing water runoff. Shelters belts, or planting lines of trees, help break the force of the wind.
Tips
A common mistake is neglecting the impact of incorrect ploughing techniques on erosion and underestimating the benefits of natural windbreaks.
