International Decade for Action, “Water for Sustainable Development”
2018-2028
• Proclaims the period from March 22th, 2018 to March, 22th, 2028 the International Decade for Action, “Water for Sustainable Development”;
• Decides that the objectives of the Decade should be a greater focus on the sustainable development and integrated management of water resources… in order to help to achieve internationally agreed water-related goals and targets;
• Decides that these objectives should be pursued, inter alia, by improving knowledge generation and dissemination, facilitating access to knowledge and exchange of good practices, generating new information relevant to the water-related Sustainable Development Goals, pursuing advocacy, networking and promoting partnership and action 7
