Q13.Not many years ago, river linking was a concept but it is becoming a reality in the country. Discuss the advantages of river linking and its possible impact on the environment.

River linking, once a concept, is now a reality in India, with projects like Ken-Betwa Link. It aims to transfer water from surplus to deficit basins to address regional water imbalances.

Advantages of River Linking

• Addresses water scarcity and mitigates floods in surplus basins.
• Enhances irrigation potential, boosting agricultural productivity and food security.
• Generates hydropower and improves inland navigation.
• Balances regional water availability, ensuring comprehensive water security.

Possible Environmental Impacts

• Causes habitat destruction and biodiversity loss, impacting ecosystems.
• Leads to displacement of human populations, requiring rehabilitation.
• Alters river hydrology, affecting water quality, sediment flow, and deltaic regions.
• Poses risks of deforestation and potential seismic activity.

While offering benefits for water and food security, river linking demands careful environmental impact assessments and sustainable implementation to mitigate ecological and socio-economic consequences.
