22 March
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.
World Water Day grew out of the 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro.
The United Nations General Assembly designated 22 March of each year as the World Day for Water. The observance of world day for water started in 1993.
"Water is at the core of sustainable development. Water resources, and the range of services they provide, underpin poverty reduction, economic growth and environmental sustainability. From food and energy security to human and environmental health, water contributes to improvements in social well-being and inclusive growth, affecting the livelihoods of billions."
