Hydropower Projects in the vicinity of the Study Area
Summary: Nepal is suffering from an acute shortage of energy (up to 16 hours of power-cut per day). Hydropower is considered to be relatively a clean source of energy; many hydropower projects (HPP) are coming up in Nepal. Access to river water is contested for drinking, livelihood, environment and hydropower. Due to lack of data and awareness, conflict between local residents and HPP proponents frequently arise during project execution.
The local government agencies (DDCs and VDCs) do not have capacity to develop and implement complicated methods of water sharing (holistic e-flow assessment, time dependent evapotranspiration and crop type/growth related water needs, and water supply and industrial water needs).
In consultation with DDCs/VDCs and their expected capacity, a simple spreadsheet based method was developed to allocate basin-wise monthly water available for HPP development.
Factors considered: monthly variations in (a) river flow, (b) e-flow, (c) crop cycle/type, (d) population increase, (e) water supply, (f) industrial and “other” water needs, and (g) rainfall.
With development of technical capacity, the method can accommodate more water demanding parameters, changes in agricultural practices/irrigation methods, and climate change impacts on river water flow.
Once the method becomes a basis for approval of a planned HPP, it is expected that the HPP development in Nepal will be comparatively conflict-less, regarding river water diversion for HPP.
