Water storage and distributed reservoirs are likely to displace people – a rehabilitation process that has attracted concern of sociologists and political groups. Further, the inter-link would create a path for aquatic ecosystems to be affected by movement of species from one river to another, which in turn may affect the livelihoods of people who rely on specific aquatic species for their income. Lakra et al., in their 2011 study, claim large dams, interbasin transfers and water withdrawal from rivers is likely to have negative as well as positive impacts on freshwater aquatic ecosystem. As regards to the impact on fish and aquatic biodiversity, there could be positive as well as negative impacts.
