Dam Solutions - Alternatives & mitigation
What are the alternatives to large dams?
Restoring environmental flows, such as is happening in the Kafue Flats in Zambia, can be beneficial to freshwater ecosystems and the people who depend on them for their livelihoods.

Where this is not possible, compensatory measures for ecosystem restoration can be considered. For example, by managing suitable, nearby land for nature conservation.
