Protests Erupt Over Mahadayi River Study Findings

Why in the News ?

A recent scientific study by CSIR-NIO and INCOIS concluded that Karnataka’s Mahadayi river diversion will have limited impact on Goa. This has sparked protests from environmental groups and political parties, citing potential threats to Goa’s ecology and water security.

Background of the Dispute:

• Mahadayi River dispute involves Karnataka and Goa, ongoing for over two decades.
• Mahadayi Water Disputes Tribunal (MWDT) gave a verdict five years ago, but tensions persist.

• The issue remains emotionally and politically sensitive in both States.

Findings of the Scientific Study

• Study titled ‘The water budget of the Mahadayi river…’ was published in the Journal of Earth System Sciences.
• Conducted by CSIR-National Institute of Oceanography (Goa) and INCOIS (Hyderabad).
• Used rainfall mapping and run-off modelling to simulate discharge points.
• Concluded that Karnataka’s diversion plan would have limited effect on Goa.
• Warned that diversion from Kalasa tributary could impact northern Mhadei Wildlife Sanctuary, but only locally.

Reactions and Protests

• The findings triggered strong backlash in Goa.
• Mhadei Movement activists staged a protest at NIO campus, Dona Paula.
• Revolutionary Goans Party (RGP) also expressed serious concerns.
• Protesters believe the study undermines ecological risks and could weaken Goa’s legal position.

• Fears remain about loss of biodiversity, water scarcity, and impact on protected areas in Goa.
