description |
This paper summarizes the results of the
Ganges Strategic Basin Assessment (SBA), a 3-year,
multi-disciplinary effort undertaken by a World Bank team in
cooperation with several leading regional research
institutions in South Asia. It begins to fill a crucial
knowledge gap, providing an initial integrated systems
perspective on the major water resources planning issues
facing the Ganges basin today, including some of the most
important infrastructure options that have been proposed for
future development. The SBA developed a set of hydrological
and economic models for the Ganges system, using modern data
sources and modeling techniques to assess the impact of
existing and potential new hydraulic structures on flooding,
hydropower, low flows, water quality and irrigation supplies
at the basin scale. It also involved repeated exchanges with
policymakers and opinion makers in the basin, during which
perceptions of the basin could be discussed and examined.
The study’s findings highlight the scale and complexity of
the Ganges basin. In particular, they refute the broadly
held view that upstream water storage, such as reservoirs in
Nepal, can fully control basin wide flooding. In addition,
the findings suggest that such dams could potentially double
low flows in the dry months. The value of doing so, however,
is surprisingly unclear and similar storage volumes could
likely be attained through better groundwater management.
Hydropower development and trade are confirmed to hold real
promise (subject to rigorous project level assessment with
particular attention to sediment and seismic risks) and, in
the near to medium term, create few significant tradeoffs
among competing water uses. Significant uncertainties,
including climate change, persist, and better data would
allow the models and their results to be further refined. |
