The Indian River Linking Project faces several significant challenges:
- Environmental Concerns: Potential ecological damage includes deforestation, soil erosion, and habitat destruction, particularly affecting areas like the Panna National Park12. The project may also lead to waterlogging and increased salinity in agricultural lands14.
- Social and Economic Issues: Displacement of communities due to land acquisition poses social unrest, while the project's high cost (estimated at $87 billion) raises questions about economic feasibility and prioritization of resources234.
- Political and Legal Challenges: Water being a state subject complicates inter-state negotiations over water sharing, leading to conflicts among states like Kerala and Tamil Nadu13. Additionally, legal ambiguities regarding water rights can hinder implementation34.
- Impact of Climate Change: Unpredictable rainfall patterns may affect the project's success, making it difficult to achieve intended benefits16.
