Water and climate change are intrinsically linked. Global climate change will increase variability in water cycle, induce extreme weather events like floods and droughts, altering streamflow seasonality, affect groundwater recharge, decrease water quality, create water pollution, altering stream flows, reducing the predictability of water availability and demand, lead to water available for sanitation and hygiene, and subsequent increased disease burdens. These impacts disproportionately affect poor and vulnerable communities. Climate change generates risks to lives, livelihoods, economy, ecology and water-related infrastructure, thus leading to the need for adaptation measures. Water security is crucial to the heart of adaptation to climate change.
