As Pakistan is heavily reliant on water for agriculture, energy production, and economic stability, climate change is now one of the most critical threats to water security. With aggravating global warming, Pakistan's uncertain and already fragile waters are under a threat from the variability of rainfall and an increase in temperatures, and glaciers receding. This paper analyzes the synergy of climate change and water security in Pakistan, the policy gaps, and strategic responses to minimize the ramifications of the reduced availability of water. The study points out the essentials for overhauling water governance, including reviewing existing practices of water management and the relevant policies. This paper advocates for strong frameworks to improve water security and boost the country's resilience to climate uncertainties.
