The correct answer is: All of the above.
Traditional agricultural practices in Manipur, like shifting cultivation, can lead to soil nutrient depletion, soil erosion, and loss of biodiversity.
Soil nutrient depletion occurs when nutrients are removed from the soil faster than they can be replenished. This can happen when crops are harvested, when animals graze on the land, or when the soil is eroded. Soil nutrient depletion can lead to a decline in crop yields and a loss of soil fertility.
Soil erosion occurs when the topsoil is removed from the land by wind or water. This can happen when the land is cleared for cultivation, when there is heavy rainfall, or when the land is not properly managed. Soil erosion can lead to a loss of topsoil, which is the most fertile layer of soil. It can also lead to a decline in crop yields and a loss of biodiversity.
Loss of biodiversity occurs when the variety of plants and animals in an area declines. This can happen when the land is cleared for cultivation, when there is hunting or poaching, or when the environment changes. Loss of biodiversity can lead to a decline in the ecosystem’s ability to provide food, water, and other resources.
Traditional agricultural practices in Manipur, like shifting cultivation, can have a number of negative impacts on the environment. These practices can lead to soil nutrient depletion, soil erosion, and loss of biodiversity. It is important to be aware of these impacts and to take steps to mitigate them.
