Nepal's Geography & Regions

Nepal may be a small country, but its geography is extraordinarily diverse. Within just 200 km from south to north, the elevation rises from 60 meters in the Terai to 8,848.86 meters at the summit of Sagarmatha. This dramatic variation creates distinct regions, climates, and ecosystems.

Physiographic Divisions

Nepal is traditionally divided into five physiographic regions from south to north:

1. Terai (तराई) - 60 to 300 m

The flat, fertile plains in southern Nepal. Often called the "granary of Nepal" because it produces most of the country's rice, wheat, and other grains. Major cities: Biratnagar, Birgunj, Nepalgunj, Dhangadhi. Home to Chitwan and Bardia National Parks with one-horned rhinos, Bengal tigers, and elephants.

2. Siwalik (शिवालिक/चुरे) - 300 to 1,500 m

The lowest hill range, consisting of young, fragile mountains. Prone to landslides and erosion. The inner valleys (called Dun or Bhitri Madhesh) like Dang and Surkhet are fertile areas.

3. Middle Hills (मध्य पहाड) - 1,500 to 2,700 m

Where the majority of Nepal's population traditionally lived. Includes the Kathmandu Valley, Pokhara Valley, and many terraced farming areas. Pleasant climate. Major crops: rice, maize, millet, potatoes.

4. High Mountains (उच्च पहाड) - 2,700 to 4,000 m

Steeper terrain with cold winters. Includes areas like Jumla, Dolpa, and parts of Solukhumbu. Alpine pastures support yak herding. Fewer people live here due to harsh conditions.

5. High Himalaya (हिमाल) - Above 4,000 m

The roof of the world. Includes eight of the world's 14 peaks above 8,000 m, including Sagarmatha (Everest), Kanchenjunga, Lhotse, and Makalu. Permanent snow and glaciers. Very sparse human settlement, mainly in valleys like Khumbu.

Climate Zones

Nepal's climate varies dramatically by altitude:

• Tropical (Terai): Hot summers (up to 45 degrees C), mild winters. Heavy monsoon rain.
• Subtropical (Lower hills): Warm and humid.
• Temperate (Middle hills): Pleasant summers, cold winters. Kathmandu's climate.
• Alpine (High mountains): Cold year-round, heavy snowfall in winter.
• Arctic/Tundra (Himalaya): Below freezing most of the year, glaciers and permanent snow.

The monsoon (June-September) brings about 80% of Nepal's annual rainfall, critical for agriculture.

Natural Resources

• Water: Nepal has enormous hydroelectric potential (estimated 83,000 MW, only about 3% developed)
• Forests: About 44% of Nepal's land is forested, providing timber, herbs, and biodiversity
• Minerals: Deposits of limestone, iron, copper, mica, and precious stones in various locations
• Fertile soil: The Terai's alluvial soil is among the most productive in South Asia

Did You Know? Nepal's elevation range is the greatest of any country relative to its size. You can experience tropical jungle, terraced hillsides, and permanent glaciers all within the same country -- a geographic miracle!

Key Takeaways

• Nepal has five physiographic regions from Terai (lowest) to High Himalaya (highest)
• Climate ranges from tropical to arctic within just 200 km
• The monsoon is critical for Nepal's agriculture and water supply
• Nepal has enormous untapped hydroelectric potential
