The correct answer is: All of the above.
Arunachal Pradesh is a state in north-eastern India. It is the largest state in the country by area, but it has a very low population density. The state is located in the Himalayas, and it has a mountainous terrain. The climate of Arunachal Pradesh is tropical, but it varies with altitude. The southern part of the state is hot and humid, while the northern part is cold and dry.
The rainfall in Arunachal Pradesh is abundant, but it is also highly seasonal. The state receives most of its rainfall during the monsoon season, which runs from June to September. During the rest of the year, the rainfall is much lower. This seasonal variation in rainfall makes it difficult to grow crops in the state.
The water resources in Arunachal Pradesh are also unevenly distributed. The southern part of the state receives more rainfall than the northern part. This means that there is a lot of water available for irrigation in the south, but there is not enough water in the north.
The topographical challenges in Arunachal Pradesh also make it difficult to develop irrigation systems. The state is mountainous, and there are many steep slopes. This makes it difficult to build canals and other infrastructure for irrigation.
All of these factors make irrigation development crucial in Arunachal Pradesh. Despite the abundant rainfall, the state needs to develop irrigation systems in order to grow crops and support its population.
Here are some additional details about each of the options:
- Seasonal variations in rainfall: The rainfall in Arunachal Pradesh is abundant, but it is also highly seasonal. The state receives most of its rainfall during the monsoon season, which runs from June to September. During the rest of the year, the rainfall is much lower. This seasonal variation in rainfall makes it difficult to grow crops in the state.
- Uneven distribution of water resources: The water resources in Arunachal Pradesh are also unevenly distributed. The southern part of the state receives more rainfall than the northern part. This means that there is a lot of water available for irrigation in the south, but there is not enough water in the north.
- Topographical challenges: The topographical challenges in Arunachal Pradesh also make it difficult to develop irrigation systems. The state is mountainous, and there are many steep slopes. This makes it difficult to build canals and other infrastructure for irrigation.
