The influence of climate variability on the availability of water is critical as it directly affects ecosystems and human livelihoods. Understanding these changes is essential for evolving adaptive strategies to mitigate water stress and ensure long-term water security. Despite the increasing identification of variable climate’s impact on water resources, examination of its upcoming implications is restricted, leaving a significant gap in understanding regional vulnerabilities. This paper attempts to analyze the impact of climate change on water availability and quality considering population growth. A bibliometric study of 582 research papers (journals) through the use of the two most prominent databases: Scopus and Google Scholar was conducted till 2024 on key terms: “climate change” and “water availability” using tools, VOSviewer 1.6.20, R Studio, and Biblioshiny. Therefore, the analysis helps get an in-depth summary of research in this domain that research scholars and individuals engaged can use to recognize probable ways for future research on water availability considering climate variability by formulating effective policies to mitigate water stress.
