What are the reason of less agricultural production in mountain and hilly region of Nepal?

Agricultural production in the mountain and hilly regions of Nepal is limited due to several factors. The rugged terrain and steep slopes make land cultivation challenging, leading to soil erosion and reduced arable land. Additionally, the harsh climate, characterized by short growing seasons and heavy rainfall, further restricts crop diversity and yields. Limited access to markets, technology, and irrigation facilities also hampers agricultural productivity in these remote areas.
