Vembanad-Kol Wetland in Kerala is the largest wetland ecosystem in the country by owing unique and diverse biodiversity and peculiar geography. It is a complex aquatic system of coastal backwaters, lagoons, marshes, mangroves etc.and is spread over the districts of Alappuzha, Kottayam, Ernakulam and Thrissur, which lies parallel to the Arabian Sea. The total area of the Vembanad wetland system is 1512 sq.km, where these areas lie 1M below MSL. The livelihood of the area fully depends on the wetland; around 9000 families depend on agriculture, 17000 families depend on fishing and so on. The signals of climate change are clearly visible in the ecological and hydrological environment, and have grown considerably over the past decade. The watershed area of the system covers over 45% of the land area of Kerala; hence, the impact directly upsets half of the population of the state. Institute for Climate Change Studies proposed a study titled “Vulnerability of Vembanad-Kol-Ramsar Wetland to Climate Change” in order to identify the pressure that exists, sensitivity, resilience and to propose adaptive strategies.
