World Water Day (WWD) is celebrated worldwide on March 22 of every year to remind the world of the importance of fresh water to mankind and to advocate sustainable management of fresh water resources. Its celebration dates back to the 1992 United Nations Conference on Environment and Development where an international observance for water was recommended. The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day. It has been held annually since then.
