The hilly terrain in Manipur poses challenges for all of the following:

• Mechanization: The hilly terrain makes it difficult to use heavy machinery, such as tractors and bulldozers. This can make it difficult to clear land for agriculture, build roads and other infrastructure, and extract natural resources.
• Transportation of produce: The hilly terrain makes it difficult to transport goods and people. This can make it difficult to get food and other essential supplies to remote areas, and can also make it difficult to get people to and from work and school.
• Soil conservation: The hilly terrain is prone to soil erosion. This can be caused by heavy rains, deforestation, and overgrazing. Soil erosion can lead to a loss of fertile land, and can also make it difficult to grow crops.

The hilly terrain in Manipur is a major challenge for the development of the state. The government is working to address these challenges, but it is a difficult task.
