Learn about the benefits and challenges of reservoir projects.

Environmental and Social Impacts of Reservoirs

While reservoirs provide significant benefits, their construction can have adverse effects on local ecosystems and communities. For instance, converting natural wetlands or backwaters into reservoirs can disrupt fish breeding habitats, affect local biodiversity, and alter natural flood-buffering functions. Additionally, such projects may impact the livelihoods of fishing communities, as seen in the case of the Mamallan reservoir in Tamil Nadu.
