Question

Hint:

Sustainable agricultural practices and afforestation can help prevent land degradation.

Answer 1

Step 1: Understanding the question. 
Land degradation refers to the process by which the land becomes less productive due to various factors. The question asks for two causes of land degradation.

Step 2: Two causes of land degradation. 
1. वृक्षों की अन्धाधुंध कटाई (Deforestation): The cutting down of trees leads to soil erosion, as there is no root system to hold the soil together. 
2. अत्यधिक कृषि (Excessive Agriculture): Over-cultivation leads to the depletion of soil nutrients, making the land unproductive. 
Step 3: Conclusion. 
Land degradation is caused by human activities such as deforestation and excessive agricultural practices, leading to the loss of soil fertility.
