This research project was undertaken to study the
climate change-induced vulnerabilities in the Helambu
sub-watershed area, mainly in water and irrigation
sectors, and deduce subsequent adaptation measures
applicable and influential to relevant policies in Nepal.
The Helambu sub-watershed is representative of many
vulnerable ecological zones of Nepal with significant
importance in terms of water supply not only to the
indigenous peoples but to the inhabitants of the
Kathmandu Valley. The research shows vulnerability
in the availability of water due to unreliability in case
of spring sources, as well as the supply system. A
demand–supply analysis of water sources showed
that all but two mapped sources were already facing
deficiencies. The research suggests coping strategies
such as maintenance of spring resources, groundwater
recharge and water storage systems. The results of this
research can provide important information to support
planning for future water availability in the Helambu
region.
