Why in news
A group of 22 scientists and ecologists urged Tamil Nadu CM M.K. Stalin to withdraw the Mamallan Reservoir project to protect the Kovalam-Nemmeli backwater system.
Background
The proposed project involves constructing a reservoir in the Kovalam-Nemmeli backwater system. Scientists argue the project would restrict tidal flow, damaging seagrass patches, mudflats, and brackish habitats.
Facts for Prelims
- PlaceKovalam-Nemmeli backwater system: A wetland ecosystem in Tamil Nadu.
- EnvironmentSeagrass patches and mudflats: Identified as essential habitats for fish and shrimp in the backwater system.
- Fact22 scientists (ecologists, hydrologists, ornithologists, and marine biologists) submitted the protest.
For Mains
Q. Discuss the ecological implications of large-scale reservoir construction in coastal backwater systems and the importance of lagoonal wetland conservation.
Dimensions to cover in your answer
- Hydrological risk: Increased flooding and cyclone vulnerability due to restricted tidal flow
- Biodiversity loss: Degradation of brackish habitats and seagrass patches essential for marine fauna
- Conservation trade-off: Balancing infrastructure development with the preservation of lagoonal wetland ecosystems
Keywords: Biodiversity conservation · Hydrological risk · Wetland ecology · Coastal vulnerability · Ecological impact assessment
