A major challenge to irrigation development in Manipur is:

Hilly terrain
Limited water resources
Lack of infrastructure
All of the above

The correct answer is: All of the above.

Manipur is a hilly state with a high population density. The state has limited water resources and a lack of infrastructure. These factors make it difficult to develop irrigation systems in Manipur.

Hilly terrain makes it difficult to build canals and other irrigation infrastructure. The state’s limited water resources mean that there is not enough water to irrigate all of the land that could be irrigated. The lack of infrastructure makes it difficult to transport water to the fields that need it.

As a result of these challenges, only a small percentage of the land in Manipur is irrigated. This limits the state’s agricultural production and makes it difficult to feed its population.

In order to improve irrigation development in Manipur, the state government needs to invest in infrastructure, such as canals and dams. The government also needs to find ways to conserve water and to make more efficient use of the water that is available.
