Understanding the Origin of World Water Day

The question asks about the location where the international initiative for World Water Day was taken on 22 March 1992 during the United Nations Conference of Environment and Development.

World Water Day is an annual United Nations observance day held on 22 March that highlights the importance of freshwater. The idea for this international day came about at a major global conference.

The United Nations Conference on Environment and Development (UNCED)

• The United Nations Conference on Environment and Development, also known as the Earth Summit, was a major international conference.
• It was held in 1992.
• A key outcome of this conference was the proposal for an international day focusing on water resources.

Location of the 1992 Conference

The United Nations Conference on Environment and Development (UNCED) in 1992 took place in the city of Rio de Janeiro, Brazil. It was at this significant environmental summit that the idea for a World Water Day was formalized.

Initiative for World Water Day

Chapter 18 of Agenda 21, the action plan adopted at the Rio de Janeiro Earth Summit, recommended the establishment of an international day for freshwater. Following this recommendation, the United Nations General Assembly adopted resolution A/RES/47/193 on 22 December 1992, which declared 22 March of each year as World Water Day.

Therefore, the international initiative for World Water Day was taken during the United Nations Conference of Environment and Development held in Rio-de-Janeiro, Brazil.
