Solarising Nepal’s irrigation canals

Solarizing Nepal’s extensive irrigation canals offers huge advantages including improved irrigation reliability, higher crop production, greater farm income and improved food and nutritional security, according to IWMI researchers.

Nepal has abundant solar energy potential, with an annual capacity of 50,000 terawatt-hours and an average of 300 sunny days per year. The largely untapped solar power in the country has the potential to transform its agriculture system as energy use in agriculture is very low compared to the South Asian average. However, its agricultural expansion is challenged by the country’s low per-capita land availability and fragmented nature of land distribution, which significantly impacts its costs and feasibility.
