UNESCO Flags Aghanashini-Vedavathi River Link

UNESCO has responded to a representation opposing the proposed Aghanashini-Vedavathi river-linking project in Karnataka and advised that any such development must comply with World Heritage Conservation norms. The issue centres on the Western Ghats, a UNESCO World Heritage site known for high ecological sensitivity, biodiversity and water security significance. Environmental activists and local groups have raised concerns that the project could disrupt fragile river systems and affect thousands of families.

Project and Opposition

The proposed plan aims to divert around 35 tmc ft of water from the Aghanashini basin and pump it to the Vedavathi river system. Critics argue that the project is scientifically unsound and could weaken the natural hydrology of the Western Ghats. A memorandum opposing the project was submitted to the UNESCO World Heritage Centre on 17 February 2026.

Ecological Concerns

The representation brought into light the following concerns:

• The Western Ghats are a globally recognised ecological hotspot.
• River diversion may affect forest cover, rainfall-fed catchments and groundwater recharge.
• Large-scale water transfer could alter local livelihoods dependent on the river basin.
• The project may threaten the ecological balance of a sensitive landscape.

UNESCO’s Position

UNESCO has emphasised that development in World Heritage areas must follow conservation rules and sustainable practices. Under the 1972 World Heritage Convention, member countries are responsible for protecting natural heritage sites within their territory. The organisation also acknowledged the concerns raised by activists and the need to safeguard natural heritage.

Significance for Policy

The controversy reflects the wider debate on river-linking projects, water redistribution and environmental safeguards. It also underlines the tension between infrastructure planning and conservation obligations in ecologically fragile regions. The case is relevant for questions on environmental governance, World Heritage protection and sustainable water management.
