Large dam projects are subject to widespread criticism due to their social and environmental impacts. The construction of dams and the creation of reservoirs often lead to the resettlement of a high number of people, as well as to major changes in the river ecosystem. This criticism equally applies to multi-purpose dams.
Sustainable development of dams is therefore pivotal to ensure that dams provide true development benefits without worsening the overall situation of the population affected by the dam. Negative social and ecological impacts are to be mitigated or compensated; the participation of all relevant stakeholders, including the affected communities, at an early stage is an important prerequisite. Since the WCD published its report in 2000, its recommendations and guidelines for sustainable development of large dam projects serve as a point of reference for environmental and social NGOs and for the German Development Cooperation. The WCD process has had a significant influence on the development of other international standards for dam projects that have since evolved, such as the safeguard policies of the World Bank or the Hydropower Sustainability Assessment Protocol by the IHA.
For multi-purpose dams, careful consideration and coordination of the interests of the different users are additional prerequisites in order to avoid conflicts. While hydropower typically generates maximum output from maximum storage levels in the reservoir, it is necessary for flood protection to keep the water level low at certain times in the year. Further trade-offs between effectiveness and productivity may arise if irrigation or water supply is combined with hydropower when water levels are low.
