Nepal's Agricultural Regions
Nepal's three agro-ecological zones have radically different soils, climates and farming systems - yet together sustain 60% of the population. From the fertile Terai plains to the terraced Hills and the high-altitude Mountains, each zone faces distinct opportunities and challenges.

Where Nepal's food comes from
Despite covering nearly half the country's land, the Hills contribute only a quarter of national food output. The Terai - Nepal's agricultural heartland - delivers 70% of food production from its alluvial plains.

Three farming worlds
From the Terai's rice paddies at 60 m to mountain barley fields at 4,000 m, each zone has its own logic - and its own pressures.

Agricultural land vs. food output by zone
The gap between agricultural area share and food production share reveals the Terai's productivity advantage: it converts land to food at nearly 1.4× the rate of the Hills.

Irrigation coverage across Nepal
Only 37% of Nepal's cultivated land is irrigated. Access is steeply unequal across zones - the Terai benefits from both river-fed canal networks and tube wells, while Hill and Mountain farming is almost entirely rain-dependent.
Terai
Most irrigated
Gravity canal systems (Narayani, Koshi, Gandak) and private tube wells support year-round double and triple cropping across the plains.
Hills
Largely rain-fed
Traditional kulo (earthen channel) irrigation supplements monsoon rains in valley bottoms, but most terraced slopes depend entirely on seasonal rainfall.
Mountains
Glacial meltwater
High-altitude farming relies on snowmelt and glacial streams. Accelerating glacier retreat is already reducing dry-season water availability in many trans-Himalayan valleys.
37% of cultivated land irrigated - 1.14 million hectares out of 3.06 million ha total. Nepal's irrigation master plan targets 70% coverage by 2030, requiring significant investment in hill-irrigation infrastructure beyond the Terai canal belt. Source: MOALD 2022/23.
What threatens each zone
Nepal's agricultural challenges are zone-specific: flooding and groundwater pressure in the Terai, labour exodus and erosion in the Hills, and climate-driven food insecurity in the Mountains.
Terai Threats
- Flood risk: Major flood events every 3–5 years destroy crops and soil fertility across the plains
- Groundwater depletion: Unregulated tube-well extraction is lowering water tables across the eastern Terai
- Land fragmentation: Average farm size has fallen below 0.7 ha, limiting mechanisation and investment
- Soil degradation: Overuse of chemical fertilisers is compressing soil organic matter and long-run productivity
Hills Threats
- Labour shortage: 60%+ of rural out-migrants are male; women bear the agricultural workload with inadequate support
- Erosion: Poorly maintained terraces on steep slopes lose topsoil during intense monsoon rainfall
- Wild animal damage: Wild boar, monkeys and bears destroy standing crops - a rising problem as forests recover
- Erratic monsoon: Climate change is shifting monsoon onset and causing drought spells mid-season
Mountain Threats
- Food insecurity: 40–60% of households lack adequate food for 3+ months per year in mountain districts (WFP)
- Glacial retreat: Shrinking glaciers reduce dry-season irrigation water as snowmelt timing shifts unpredictably
- GLOF risk: Glacial lake outburst floods threaten mountain terraces and downstream settlements
- Climate change: Warming is altering planting calendars; new pest species are reaching previously cold highlands
“40–60% of households in Nepal's mountain districts face food insecurity for 3 or more months each year.”
World Food Programme - Nepal Food Security Brief 2023
Unlike seasonal food insecurity elsewhere, the mountain food gap is structural. Very limited arable land (just 5% of Nepal's agricultural area), a growing season compressed to four months, near-zero market access and rapid glacial retreat form a compound vulnerability that climate change is accelerating. WFP food assistance programmes, high-altitude seed banks and cash transfer programmes attempt to close the gap - but the structural drivers are deepening.
Nepal's farming zones, answered
Which region of Nepal produces the most food?+
The Terai (Southern Plains) produces approximately 70% of Nepal's food despite covering only 17% of the country's land area. Its fertile alluvial soils and access to irrigation support rice–wheat–maize triple-cropping.
How much of Nepal's cultivated land is irrigated?+
About 37% of Nepal's cultivated land (roughly 1.14 million of 3.06 million hectares) has access to irrigation. Irrigation is most prevalent in the Terai, where both canal networks and tube wells are used; the Hills remain largely rain-fed.
What crops are grown in the Nepal Mountains?+
High-altitude mountain farming in Nepal centres on potato, buckwheat, barley, and finger millet - cold-tolerant crops suited to the short growing season (May–September). Medicinal and aromatic plants including yarshagumba (caterpillar fungus) and various herbs are also harvested.
Why do Nepal's mountains face food insecurity?+
Remoteness, very limited arable land (just 5% of the country's agricultural area), a short growing season, high out-migration, and accelerating climate change together mean 40–60% of households in mountain districts face food deficits for three or more months each year, according to WFP data.
What is the main farming challenge in Nepal's Hills?+
Labour shortage is the defining challenge. Mass male out-migration to India and the Gulf has feminised hill agriculture; women now manage most terraced farms, often without adequate inputs or mechanisation. Soil erosion on steep terraces and wild animal crop damage compound the pressure.
