At the meeting, the World Water Day 2018 theme, the campaign objectives and determination on the organization and participation methods were brought up for discussion. Accordingly, the World Water Day 2018 campaign will be organized together by the Convention on Biological Diversity; United Nations Educational Scientific and Cultural Organization (UNESCO); UN Environment Programme, under the support of UN members and partners.
The choice of "Nature for Water" as the World Water Day 2018 theme showed potentials of nature-based solutions for water and how to implement policies and practices of water resources management.
At the United Nations Conference on Environment and Development held in Rio de Janeiro from June 3 - 14, 1992, the resolution that 22 March of each year was declared World Day for Water and annually commemorated since 1993 was issued by the UN. This international event is to attract the attention from people around the world into the vital importance of water, especially of clean water resources, as well as to contribute to the sustainable management of this precious resource.
