HISTORICAL SCIENCCE
On June 3rd -14th 1992, Rio de Janeiro, Brazil, held the United Nations Conference for Environment and Development. One of the most important issues was the need of using integrated criteria for the exploitation, distribution and use of freshwater resources in the planet in order to protect their quality and secure their supply. This issue is known as Chapter 18 of Agenda 21. Participants to the meeting agreed to propose the United Nations to consider the possibility of establishing a World Water Day so that all countries worldwide carried out activities to promote water user education as regards water use, saving and conservation. That very year, the United Nations General Assembly designated March 22nd as WORLD WATER DAY. This day is celebrated in Cuba since 1993.
