Ramsar Convention , to which India is a signatory is related to conservation and wise use of :

The Ramsar Convention, adopted in 1971 in Ramsar, Iran, is an intergovernmental treaty specifically dedicated to the conservation and 'wise use' of wetlands and their resources [1]. It is the only global environmental treaty that focuses on a particular ecosystem. India became a contracting party to the convention on February 1, 1982 [4]. The 'wise use' concept is defined as maintaining the ecological character of wetlands through ecosystem approaches within the context of sustainable development [4]. Member countries commit to identifying and designating wetlands of international importance to the Ramsar List to ensure their long-term conservation [5]. As of recent updates, India has significantly expanded its network of Ramsar sites, reaching a tally of 85 designated wetlands covering approximately 1.35 million hectares [5]. The convention works in collaboration with international organizations like the IUCN and WWF to protect these critical habitats [1].
