Eastern Development Region (Nepal)

Geography and environment

The region stretched across lowland agricultural plains, mid-hill valleys and some of the highest mountains on Earth. It included parts of the Mahabharat range and the high Himalaya where major peaks such as Mount Everest and Kanchenjunga lie. This geographic diversity supports a variety of ecosystems, from subtropical forests and tea gardens to alpine terrain and glacial zones.

Administrative composition

Before Nepal’s federal restructuring, the Eastern Development Region was formed from three zones and numerous districts. Principal divisions included:

• Mechi Zone
• Koshi Zone
• Sagarmatha Zone

Major districts and urban centres within the region included Jhapa, Ilam, Morang (home to Biratnagar), Sunsari, Dhankuta and Solukhumbu (the Everest area).

Economy, society and significance

The economy combined agriculture in the Terai, tea cultivation in hill districts such as Ilam, industrial activity around Biratnagar and tourism focused on trekking and mountaineering in the high mountains. The region is ethnically and linguistically diverse, with many communities and languages contributing to its cultural landscape.

History and legacy

The system of development regions was introduced as a means of decentralising administration in the 1970s and remained in use until the 2015 constitution created a federal structure of provinces. Although the Eastern Development Region no longer exists as an administrative unit, the name and concept are still used in geographic descriptions, planning histories and discussions of regional development.
