The correct answer is: d) All of the above.
Deforestation, overgrazing, and improper agricultural practices are all major causes of soil erosion. Deforestation removes trees, which help to hold soil in place. Overgrazing can compact the soil and make it more susceptible to erosion. Improper agricultural practices, such as tilling the soil too deeply or planting crops on steep slopes, can also lead to soil erosion.
Soil erosion is a serious problem in Kerala. It can lead to a loss of topsoil, which is the most fertile layer of soil. It can also damage infrastructure, such as roads and bridges. Soil erosion can also contribute to flooding and landslides.
There are a number of things that can be done to prevent soil erosion in Kerala. These include:
- Reforestation: Planting trees helps to hold soil in place.
- Grazing management: Grazing animals should be rotated to different areas to prevent overgrazing.
- Soil conservation practices: These practices include terracing, contour farming, and mulching.
- Sustainable agriculture: This type of agriculture minimizes the impact on the environment.
By taking these steps, we can help to prevent soil erosion in Kerala and protect our environment.
