On 20 December 2018 the General Assembly adopted the resolution on the “Midterm comprehensive review of the implementation of the International Decade for Action, ‘Water for Sustainable Development’ 2018-2028”. (A/RES/73/226).
The resolution calls for a Conference on the Midterm Comprehensive Review of the Implementation of the Objectives of the International Decade for Action to be convened in New York from 22 to 24 March 2023.
The resolution decides that the Conference shall be preceded by regional and global preparatory meetings, as appropriate, and informed by existing water-related meetings at the regional and global level.
The President of the General Assembly was requested to hold a one-day high-level meeting in 2021 to help promote the implementation of the water-related Goals and targets of the 2030 Agenda.
The resolution requests the Secretary-General to coordinate the preparatory process and to invite all relevant organizations of the United Nations system, including the regional commissions and other relevant organizations, within their respective mandates, to provide support to the review process.
The resolution decides that all costs relating to the 2023 Conference and its preparatory process shall be financed through voluntary contributions and to finalise the arrangements for the 2023 Conference during its seventy-fifth session.
As an initial activity for the preparatory process, UN-Water held in November 2019 a side event to provide an opportunity for stakeholders, specially UN Member States, to reflect on how to plan for the Conference and the preparatory process. A summary of the event including general principals and draft proposals for the events can be downloaded here.
