Wetlands and their associated ecosystem services are severely threatened by the impact of climate change and global warming which can be detrimental for biodiversity and ethnic communities. The Tsomoriri Lake is a High-Altitude Wetland located at an altitude of more than 4500 m in the Changthang Plateau, the western extension of the Tibetan Plateau. It has been declared as a Wetland of International Importance and is protected under the Ramsar Convention due to it’s unique and endemic faunal diversity. Changpas, the ethnic nomadic tribes have been inhabiting the Changthang Plateau since time unknown to human history. These communities practice pastoralism as their primary source of occupation and have been utilizing the lake pastures as fodder for their livestock. The risk of glacial melting and long-term fluctuations in temperature and rainfall is perceptible and experienced by these communities through changes in their migratory patterns, shortage of water, declining availability of fodder, herd-size composition etc. Recent developments such as expansion of tourism and accompanied infrastructural developments exaggerates these risks due to increased anthropogenic pressure. This paper is an attempt to explore this entwined complicated relationship and its long-term impacts on traditional practices which are a part of our intangible heritage.
