WORLD WATER DAY is held annually on 22 March to focus attention on the importance of freshwater and for advocating the sustainable management of freshwater resources. The United Nations General Assembly initiated this as a response on 22 March 1993 as the first World Water Day. In 2022, World Water Day is celebrated under the THEME “GROUNDWATER : MAKING THE INVISIBLE VISIBLE” where UNESCO is the lead UN agency. Also, a new World Water Development Report is released each year on or near World Water Day to provide decision-makers with tools to formulate and implement sustainable water policies. This report is coordinated by UNESCO’s World Water Development Programme (WWAP) on behalf of UN-Water.
