India faces a growing water crisis driven by climate change, urbanisation, and population pressures. Wetlands, vital for water security, flood control, and biodiversity, are rapidly declining due to encroachment and pollution. Cities like Chennai, Hyderabad, and Gurugram illustrate the consequences of their loss. While policy recognition exists, implementation gaps remain. Restoring wetlands requires integrated planning, community participation, science-based monitoring, and innovative financing. Protecting these ecosystems is essential for climate resilience, sustainable development, and securing India’s water future.
