In December 2010, the United Nations General Assembly declared 2013 as the United Nations International Year of Water Cooperation (Resolution A/RES/65/154). In reflection of this declaration, the 2013 World Water Day, which will take place on 22 March 2013, also will be dedicated to water cooperation. Therefore, UN-Water has called upon UNESCO to lead the 2013 United Nations International Year on Water Cooperation, in particular because of the Organization’s unique multidisciplinary approach which blends the natural and social sciences, education, culture and communication. Given the intrinsic nature of water as a transversal and universal element, the United Nations International Year on Water Cooperation naturally would embrace and touch upon all these aspects.
The objective of this International Year is to raise awareness, both on the potential for increased cooperation, and on the challenges facing water management in light of the increase in demand for water access, allocation and services. The Year will highlight the history of successful water cooperation initiatives, as well as identify burning issues on water education, water diplomacy, transboundary water management, financing cooperation, national/international legal frameworks, and the linkages with the Millennium Development Goals. It also will provide an opportunity to capitalize on the momentum created at the United Nations Conference on Sustainable Development (Rio+20), and to support the formulation of new objectives that will contribute towards developing water resources that are truly sustainable.
