World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.
An international day to celebrate freshwater was recommended at the 1992 United Nations Conference on Environment and Development (UNCED). The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day.
Each year, World Water Day highlights a specific aspect of freshwater. Under the theme ‘Water and Sustainable Development’, the year 2015 provides an important opportunity to consolidate and build upon the previous World Water Days to highlight water's role in the sustainable development agenda.
