This day was first formally proposed in Agenda 21 of the 1992 United Nations
Observance began in 1993 and has grown significantly ever since.
The UN and its member nations devote this day to implementing UN
recommendations and promoting concrete activities within their countries
regarding the world's water resources. Each year, one of various UN agencies
involved in water issues takes the lead in promoting and coordinating international
activities for World Water Day. Since its inception in 2003, UN-Water has been
responsible for selecting the theme, messages and lead UN agency for the World Day for Water.
