Most villages in the Dolpo are between 3,500 and 4,000 metres. The growing season is very short. Field crops here are basic, barley, buckwheat and potatoes. Vegetables that can be grown in greenhouses – greens, carrots, cucumber, cauliflower, cabbage and squash, even tomatoes – dramatically improve nutrition and food security.
When I first traveled to Dolpo in 2015, I saw very few greenhouses, maybe five or six. When I returned in 2017, there were at least 15 – 20 in the same region. The popularity of greenhouses attached to homes is increasing exponentially. There were many requests for greenhouses in 2020. A generous sponsor provided dedicated funds for 10 greenhouses. Our goal was to provide materials for another 10 – 20 greenhouses. At last report we heard 26 greenhouses were under construction and would be completed before winter of 2020.
The cost of greenhouse materials and their transportation is ~ $500 US per greenhouse. Materials such as plastic, wire, hardware, seed and irrigation equipment are purchased in Kathmandu. Any wood products needed for doors and vents are purchased in the Lower Dolpo. Structural walls are made from local materials such as stone and / or rammed earth.
Greenhouses are becoming critical for food security as the Dolpo is increasingly impacted by climate change. Seasonal precipitation patterns have become erratic, some years there is not enough snow to provide melt water for the villagers water needs, other years there is too much snow and people and their livestock are killed by avalanches. In recent summers, unusually heavy rains have caused washouts of trails, small bridges and the terraces that are used to grow their staple crops.

Greenhouses are a multifunctional amenity here. Schools use them as a warm well lit classroom in the winter.
Villagers often build their greenhouse attached to the south side of their home. It helps heat the home in the winter months, and it provides them with a warm bright room for weaving, and for household and community affairs.
We sponsored the building of this greenhouse for Saldang School.
The greenhouse at Saldang is a tremendous asset to both the school and the village. It provides better food security by extending the growing season and improving the quality of fresh vegetables for the student lunches and staff meals. In winter, a monk from the monastery holds classes for students to learn about their Tibetan history and culture. The greenhouse is providing them with a warm and bright classroom on sunny winter days!
