World Water Day
"World Water Day is an international observance and an opportunity to
learn more about water related issues, be inspired to tell others and
take action to make a difference. World Water Day 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. Each year,
UN-Water — the entity that coordinates the UN’s work on water and
sanitation — sets a theme for World Water Day corresponding to a current
or future challenge. The engagement campaign is coordinated by one or
several of the UN-Water Members with a related mandate."
