2. Strip cropping
3. Jhumming
4. Mixed farming.
A) 1 and 2
B) 1 and 3
C) 2 and 4
D) 2 and 3

Answer 1

Hint: Soil erosion removal of topsoil; it is a method of soil degradation. This process is the result of the intense activity of floodwaters, namely, water, ice, ice, wind, plants, animals, and humans.

Complete answer:
Soil erosion loss of the top layer of fertile soil can be wind or water.Land collection is a method used to prevent soil erosion.Contour lines form breaks to assist in the construction of pits during the flow of water It is a method of cultivation where planting is followed by hand-made soil height. It helps with soil conservation and is a low and easy way.Crop sowing: Planting where different crops are planted in other rows to prevent soil erosion. Sowing in mountain rows prevents soil erosion.Threading is a type of planting strategy designed to reduce wind speed Belt cultivation is nothing more than the growth of plants in standard targeted tracts for wind flowing in the region.The lines create slow water flow during the rainy season to prevent soil erosion and allow water time to enter the soil. Line cutting is a method of plowing used when the slope is too high or too long, or otherwise when one has no other means of preventing soil erosion.Overgrazing is caused by intensive cattle raising. As plants don’t have the recovery period they need, they end up being crushed and compacted by cattle. Soil erosion reduces cropland productivity and contributes to the pollution of adjacent watercourses, wetlands and lakes.

Additional Information:Soil erosion can be a slow process that continues unabated or can occur at an alarming rate, resulting in significant loss of topsoil. Soil compaction, low matter, loss of soil structure, poor internal flow, overflow and salinity and soil acid problems are some of the most severe soil degradation conditions that can accelerate the erosion process.

So,The correct answer is option (A), both 1 and 2.

Note: The most effective way to reduce soil erosion is to ensure surface coverage of the earth's surface, such as trees, pastures, or pastures. However, compared with the original forest soil, the soil in pastures and planting areas has a lower grip strength and can be easily eroded.
