Introduction
Ecosystem restoration is the process of assisting the recovery of ecosystems that have been degraded, damaged, or destroyed to regain ecological integrity, functionality, and biodiversity. It directly underpins global conservation roadmaps, including the UN Decade on Ecosystem Restoration (2021–2030) and Target 2 of the Kunming-Montreal Global Biodiversity Framework, which mandates restoring at least 30% of degraded terrestrial, inland water, and marine ecosystems by 2030.
Core Benefits and India's Restoration Initiatives
Ecosystem restoration provides critical ecosystem services ranging from carbon sequestration to disaster risk mitigation, substantiated by key targeted initiatives in India:
- Carbon Sequestration and Soil Health: Restoring degraded land expands terrestrial carbon sinks and restores soil organic carbon, advancing Land Degradation Neutrality (LDN). Under the international Bonn Challenge, India committed to restoring 26 million hectares (Mha) of degraded land by 2030, with more than 21.7 Mha already brought under restorative interventions.
- Coastal Defense and Disaster Resilience: Coastal habitats such as mangroves and mudflats attenuate storm surges, reduce wave energy, and prevent shoreline erosion. India introduced the MISHTI (Mangrove Initiative for Shoreline Habitats & Tangible Incomes) scheme to restore 540 sq km of mangroves across 11 coastal states and Union Territories by converging CAMPA funds with MGNREGS.
- Hydrological Regulation and Water Security: Restoring river basins and wetlands purifies freshwater, mitigates floods, and recharges ground aquifers. The Namami Gange mission, recognized by the UN as one of the World Restoration Flagships, integrates sewage interception with over 30,000 hectares of catchment afforestation. Complementing this, the Amrit Dharohar initiative promotes community-driven conservation and eco-tourism across Ramsar wetland sites.
- Combating Desertification and Habitat Recovery: Halting arid expansion re-establishes ecological corridors and sustains traditional livelihoods. The Aravalli Green Wall Project establishes a 5-km-wide green ecological buffer across four states to arrest eastward Thar desertification, while the ecological revival of Gujarat's Banni Grasslands systematically removes the invasive Prosopis juliflora to recover indigenous pastoral ecosystems.
Way Forward
To maximize sustainability, restoration efforts must transition from target-driven monoculture plantations to genuine ecological restoration. Interventions should prioritize diverse native polycultures, re-establish natural hydrological cycles, and empower Gram Sabhas under the Forest Rights Act (FRA), 2006, ensuring decentralized stewardship and sustained livelihoods.
Conclusion
Ecosystem restoration represents a vital nature-based solution to mitigate the intertwined crises of climate change and biodiversity loss. By aligning scientific ecological restoration principles with local community governance, India can achieve its sustainable development goals while fostering resilient, thriving ecosystems for future generations.
