CLIMATE CHANGE IMPACT ON WATER SUPPLY SYSTEM SUSTAINABILITY

Climate change has already started water crisis in different parts of the world likely intense floods, long droughts and many more. The most severe impacts of climate crisis will already have realized and its water. If coping action will not start soon, impacts will be worst in coming days. As per the Intercontinental panel for climate change (IPCC) forecast currently two billion people across the world are living with water-stressed situation, if the situation will continue more, the half the world¿s population will be in water stressed by 2050. Based on the projection people across the globe will face 40% shortfalls with safe water in 10 years. Climate change negatively affects drinking water availability and quality, and the performance of sanitation, wastewater and hygiene services. Likely more-frequent combined sewer overflows can flood and pollute low-lying and/or densely populated areas and receiving waters, while drought can increase the use of poorly treated wastewater for the urban and peri-urban agriculture. Therefore, it is essential that Water, Sanitation and Hygiene (WASH) infrastructure and services are adapted to make them sustainable, safe and resilient.
