Ladakh Adopts Greenhouse Farming for Food Security
Ladakh’s harsh climate once made farming a seasonal and uncertain venture. Now, thanks to greenhouse innovations tailored to local conditions, farming thrives even through sub-zero winters. From trench houses to low tunnels and organic practices, protected cultivation is reshaping agriculture in this high-altitude desert—boosting food security, productivity, and livelihoods in one of India’s most climate-challenged regions.
Greenhouses in Ladakh have evolved significantly since the 1960s. From mud-brick shelters to triple-layered polycarbonate structures, these models now support year-round cultivation of spinach, kale, tomatoes, and fruit nurseries. Built partially underground and oriented to maximise sunlight, they raise internal temperatures by 7–8°C. This simple innovation has dramatically extended the growing season and stabilised food supplies in a region with limited arable land.
Research has shown that larger greenhouses produce significantly higher yields. Cucumbers grown in large greenhouses yielded up to 2.1 kg per plant—nearly 20 times more than in open fields. Brinjal and capsicum showed similar increases. Larger structures offer better thermal control, humidity stability, and vertical space. These findings debunk the notion that greenhouse size has limited influence on productivity in extreme climates.
Cost-effective trench greenhouses and low tunnels are expanding access to protected cultivation. These structures, promoted by DIHAR and SKUAST, are built using local materials and polythene covers. In winter, trench units stay up to 20°C warmer than outside. Low tunnels, meanwhile, have tripled cabbage yields and accelerated seedling growth. Together, they offer scalable solutions for smallholder farmers with minimal land and income.
Greenhouse systems in Ladakh are increasingly being integrated with organic practices. The region’s minimal chemical use and traditional composting give it an edge in certified organic agriculture. Compost, biofertilisers, and pest-resistant crop varieties are improving sustainability. Additionally, solar greenhouses now support both crop cultivation and produce drying, offering income through value addition. These strategies enhance resilience and appeal to eco-conscious consumers and markets.
Ladakh’s adoption of protected cultivation and organic practices marks a transformative step for cold-climate farming. With over 30 vegetable varieties now cultivated year-round, the region is building a food-secure, climate-resilient agricultural system. As these innovations spread, Ladakh is emerging as a global example of how traditional wisdom and scientific research can converge to make barren landscapes fertile, sustainable, and economically empowering.
