Why is the Tarai important for agriculture in Nepal?

The Tarai is vital to Nepal’s agriculture primarily because it contains the country's most significant potential for increased production. Unlike the mid-mountain region, where nearly all arable land is already under cultivation, the Tarai offers a more favorable landscape for agricultural expansion.1

This region is characterized by low, flat, and fertile land that forms the northern extension of the Gangetic Plain. A 10-mile-wide belt of particularly rich agricultural soil stretches along its southern portion. Because of its productivity, the Tarai serves as a key source of food grains, producing a surplus that is often exported to India. Furthermore, the region supports various agro-based industries, hosting numerous rice and oil mills as well as sugar factories.213

While the Tarai is essential for the national economy, it is important to note that agricultural output across Nepal remains vulnerable to weather fluctuations due to limited irrigation. Additionally, the region faces environmental challenges, including the depletion of valuable forests and periodic flooding.145
