The correct answer is: d) All of the above
Sustainable land management practices are those that protect the land and its resources for future generations. They include practices such as:
- Preventing soil erosion: This can be done by planting trees and other vegetation, terracing the land, and using cover crops.
- Enhancing soil fertility: This can be done by adding organic matter to the soil, rotating crops, and using cover crops.
- Improving crop yields: This can be done by using improved seeds, planting at the right time, and applying fertilizer.
The government of Nagaland promotes sustainable land management practices because they are essential for the long-term health of the state’s economy and environment. Sustainable land management practices can help to prevent soil erosion, enhance soil fertility, and improve crop yields. This can lead to increased agricultural production, which can help to improve the livelihoods of farmers and reduce poverty. Sustainable land management practices can also help to protect the environment by reducing pollution and conserving water resources.
Here are some additional details about each of the options:
- Prevent soil erosion: Soil erosion is the process of soil being carried away by wind or water. It can be caused by natural processes such as rainfall and wind, or by human activities such as deforestation and agriculture. Soil erosion can lead to a loss of topsoil, which is the most fertile layer of soil. It can also lead to sedimentation in rivers and streams, which can damage aquatic ecosystems.
- Enhance soil fertility: Soil fertility is the ability of soil to support plant growth. It is determined by the amount of organic matter, nutrients, and water in the soil. Soil fertility can be improved by adding organic matter to the soil, rotating crops, and using cover crops.
- Improve crop yields: Crop yields are the amount of crops that are produced per unit area of land. They can be improved by using improved seeds, planting at the right time, and applying fertilizer.
