Nepal's Three Geographic Regions: Mountains, Hills & Plains

Nepal's dramatic elevation gradient—from 60 m to 8,848 m in <200 km—creates three distinct **physiographic regions** running east-west:

1. Himalayas (High Mountains) — 23.38% of Land

• Elevation: 3,000–8,848 m (Everest / Sagarmatha).
• Climate: Alpine, nival; permanent snow >5,000 m.
• Population: Sparse (Sherpa, Tibetan groups); transhumant pastoralism, tourism.
• Key: 8 of world's 14 8,000m peaks; glaciers feed major rivers.

2. Hill Region (Pahad, Foothills & Valleys) — 67.57%

• Elevation: 600–3,000 m.
• Climate: Subtropical to temperate; distinct seasons.
• Population: **Most dense** — Kathmandu Valley (capital), Pokhara, Gorkha, traditional farming (terraced rice, maize, millet).
• Culture: Newar, Brahmin/Chhetri, Magar, Gurung, Tamang heartlands.

3. Terai (Plains) — 8.64%

• Elevation: 60–600 m; northern extension of Indo-Gangetic Plain.
• Climate: Subtropical/tropical; hot summers, mild winters.
• Population: Fast-growing (migration from hills); **agricultural breadbasket** (rice, wheat, sugarcane, jute).
• Wildlife: Chitwan, Bardia, Shuklaphanta NPs — tiger, rhino, elephant.
• Industry: Border trade (Birgunj, Bhairahawa, Nepalgunj), manufacturing.

Why It Matters

These regions dictate **climate, agriculture, ethnicity, language, infrastructure, disaster risk (quakes, floods, landslides), and development policy**. Nepal's federal provinces (7) cut across them—creating governance challenges.
