It is evident that more individuals are putting climate change adaptation plans into practice to guarantee water security. The global water cycle has seen major changes due to climate change, as highlighted in the IPCC’s Sixth Assessment Report. In 2019, India ranked as the 7th most affected country by climate change-induced extreme weather events, leading to substantial fatalities and economic losses, with 17 out of 20 people vulnerable to severe hydrological and meteorological disasters. Ramanathapuram is the most vulnerable district in Tamil Nadu, according to the Climate Change Impacts and Vulnerability Assessment, underscoring the critical need to tackle the issues exclusively in the water resource management. A primary strategy for building resilience in such vulnerable areas connected to the water resources are to reduce water demand through improved efficiency. While existing literature underscores the importance of adaptive strategies in mitigating these impacts but the localized studies focusing specifically on Ramanathapuram district remains sparse.
