Comment on negative impacts for local communities

The cumulative impact assessment considers various scenarios for hydropower and irrigation development which include one dam in operation, another under construction, and at least six more proposed projects in Laos' Nam Ngum basin, including Nam Bak 1. The study finds that blocked migration routes, destruction of riverine habitat, and water quality problems caused by these dams would gravely threaten the basin's fisheries, including the productive fishery of the existing Nam Ngum 1 reservoir.
