WaterAid is an international non-governmental organisation, focused on water, sanitation and hygiene. It was set up in 1981 as a response to the UN International Drinking Water decade. As of 2018, it was operating in 34 countries. Sustainable and safe water, sanitation and hygiene are important to live a full and healthy life. As simple as it sounds, it is not the case for many Pakistanis who are deprived of safe WASH despite it being a basic necessity of life. WaterAid’s mission continues till the day everyone, everywhere has access to safe WASH. Changing weather patterns and climate change have a profound impact on WASH and public health. Evidence indicates that climate change will exacerbate the WASH related health issues in the future. If so, this can undermine Pakistan’s ability to meet the SDG-6 targets and cope with the situation because of its increasing urban population, evolving demography, economic conditions, health indicators, and its vulnerability to climatic conditions.
