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 through a number of processes, including crop harvesting, erosion, and leaching. When nutrients are depleted, the soil becomes less fertile and less able to support plant growth.
Soil erosion is the process of soil being carried away by wind or water. This can happen when the soil is exposed to the elements, such as when trees are cleared for cultivation. Erosion can also be caused by heavy rains or flooding. When soil is eroded, it can no longer be used for agriculture or other purposes.
Loss of biodiversity occurs when the variety of plants and animals in an area decreases. This can happen for a number of reasons, including habitat destruction, hunting, and pollution. When biodiversity is lost, it can have a number of negative consequences, such as the disruption of ecosystems and the loss of food sources.
Traditional agricultural practices in Manipur, like shifting cultivation, can have a number of negative environmental impacts. 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.
