Question

There is little irrigation in the Himalayan region in spite of large number of big rivers. Why?

[Hint: There is little agricultural land due to rugged topography and the rivers are swift flowing]

Answer 1

The Himalayan region has very little irrigation, even though there are many big rivers, because the land is mostly mountainous and uneven, so there is very little flat land for farming. The rivers here flow very fast down steep slopes and through deep valleys, which makes it hard and costly to build canals or use the water for irrigation. So, even though there is plenty of water, the land and river conditions make irrigation difficult.
