Sagarmatha Zone — geography, districts, history and significance

Geography and environment

Sagarmatha spanned terrain from the high Himalayas in the north — part of the larger Himalayas — down through temperate hills to the subtropical Terai in the south. The northernmost district contains Sagarmatha National Park, a UNESCO World Heritage site that includes Mount Everest (Everest) and protected alpine ecosystems. The zone bordered China to the north and India to the south, with the Koshi region to the east and the Janakpur Zone to the west.

Districts

Administratively, Sagarmatha was divided into six districts which ranged from lowland agricultural plains to high-mountain communities. The six districts were:

• Saptari
• Siraha
• Udayapur
• Khotang
• Okhaldhunga
• Solukhumbu

The principal town and administrative centre was Rajbiraj in the Terai, which served as the zone headquarters and as a local market and service hub for the surrounding agricultural districts. The hill and mountain districts contain smaller towns and villages often centered on trade routes, grazing areas and trekking trails.

History and administrative change

Sagarmatha functioned as a formal zone within Nepal's older administrative framework and is often described in sources covering the fourteen-zone system of the country. Under the constitution promulgated in 2015 Nepal reorganized into provinces and abolished the zone structure; the districts of the former Sagarmatha Zone were reassigned chiefly to the newly formed provinces of eastern and southern Nepal, reflecting a shift from zones to federal provinces and local governance.

Economy, culture and significance

The zone combined contrasting economic activities: intensive agriculture, rice and other crops in the Terai; hill farming and trade in central districts; and tourism and mountaineering in the Solukhumbu area. It hosts diverse ethnolinguistic groups and languages, including Nepali and several Terai languages. Sagarmatha's international profile rests largely on Mount Everest and the routes that bring trekkers and climbers, while its lowlands support markets, roads and cross-border links with India and the broader eastern Nepali region (eastern Nepal).
