Shifting cultivation, also known as ‘jhum’, is a traditional agricultural practice in which farmers clear a piece of land by cutting and burning the vegetation, then cultivate crops on that land for a few years before moving on to another plot. This practice is often used in hilly regions, where the land is not suitable for permanent cultivation.
The Imphal Valley is a lowland region in the center of Manipur, India. It is the most densely populated part of the state, and is home to the capital city of Imphal. The valley is not suitable for shifting cultivation, as the land is too fertile and the population density is too high.
Coastal areas are also not suitable for shifting cultivation, as the land is often saline and the climate is not conducive to growing crops.
Urban centers are also not suitable for shifting cultivation, as the land is too valuable for agriculture and the population density is too high.
Therefore, the correct answer is: Hilly regions of Manipur.
