The traditional cultivation of oyster mushrooms in Nepal, which has required burning large quantities of wood, has been replaced by the environmentally friendly use of solar power, thanks to a project supported by the UN Development Programme (UNDP).
Mushrooms are nutritious, do not require soil in which to grow, and represent a high value crop in the mountainous Asian country. However, the soil-free growing method does require a steaming process in a drum, using firewood.
The practice has led to deforestation and an increase in harmful climate change-inducing carbon dioxide. But now solar water heaters are being used as part of the process.
