India, June 5 -- As the world observes World Environment Day 2026, with the theme, "Inspired by Nature. For Climate. For Our Future", the global conversation on climate change is increasingly turning towards nature-based solutions. While technology and infrastructure remain essential components of climate action, they alone cannot address the scale of the challenge. Equally important is investing in nature-based solutions that enhance resilience while also delivering multiple ecological and social benefits. Healthy ecosystems- including forests, grasslands, mangroves and wetlands -offer some of the most effective, affordable and sustainable solutions for addressing climate change. Among the various natural ecosystems, wetlands occupy a unique position. They are simultaneously providers of water security, biodiversity conservation, disaster-risk reduction and climate regulation, thus offering critical support in strengthening climate resilience. Wetlands capture and store excess rainwater during intense precipitation events and gradually release it during dry periods. This natural regulation helps reduce flood risks while enhancing resilience to drought conditions. Additionally, wetlands replenish groundwater reserves, improve water quality and play a crucial role in maintaining the balance and stability of local water systems. Wetlands also make a significant contribution to climate change mitigation. Among the most efficient natural carbon reservoirs on the planet, these ecosystems lock away substantial amounts of carbon within their soils and vegetation. Unlike engineered solutions, wetlands provide multiple benefits simultaneously - water storage, flood moderation, biodiversity conservation, carbon sequestration and livelihood support. India, home to a remarkable diversity of wetlands, has much at stake. From the high-altitude wetlands of the Himalayas to the mangroves of the Sundarbans and the floodplains of the Ganga-Brahmaputra basin, these ecosystems underpin ecological and economic security for millions of people. Their conservation is therefore not merely an environmental objective; it is a national climate adaptation strategy. India has emerged as a global leader in wetland conservation, with an expanding network of Ramsar Sites. Few places illustrate the climate value of wetlands more vividly than Keoladeo National Park in Bharatpur. As one of India's most celebrated wetland ecosystems, designated both a Ramsar Site and a UNESCO World Heritage Site, Keoladeo demonstrates how conservation can simultaneously advance biodiversity protection and climate resilience. Through scientific water management, habitat restoration and adaptive conservation practices, the wetland continues to maintain critical ecological functions even during periods of rainfall uncertainty. However, recent studies suggest that over 20% of the world's wetlands have vanished since 1970, placing them among the most rapidly declining ecosystems. Wetlands face pressures from encroachment, pollution, invasive species, altered hydrological regimes and unsustainable land-use practices. Climate change further compounds these threats. The conservation of wetlands requires sustained policy support, investment, scientific management and public support. Our wetlands need interventions such as habitat restoration including scientific water management and invasive species control, biodiversity monitoring and ecosystem-based conservation planning. As India advances toward its climate commitments and sustainable development goals, conservation of natural ecosystems such as wetlands must become a central pillar of climate policy. Every wetland conserved is an investment in climate security. Every wetland restored strengthens our capacity to cope with an uncertain climatic future....
