SIWI provided water and climate advisory services throughout 2023. As part of the Sanitation and Water for All partnership, SIWI gave input during the development of the new water guidelines for the Green Climate Fund as well as to a submission for the GGA ahead of COP28, both of which now have high relevance for water and sanitation projects.

The UNDP-SIWI Water Governance Facility provided support to the Nigerian National Council on Climate Change and the Federal Ministry of Water Resources through UNDP’s Climate Promise II. Ultimately, several water-related deliverables were included in the programme, including the preparation of climate adaptation action plans in partnership with two basin authorities that address climate and water challenges in parallel, as well as the enrolment of Nigeria in the globally significant Water Tracker. 

Following consistent engagement between the Global Environment Facility (GEF) and SIWI, GEF is supporting regional investments that apply the integrated source-to-sea approach in the creation of multi-state cooperation frameworks in transboundary deltas through its GEF-8 programme. At the 22^nd GEF Large Marine Ecosystem (LME) Consultative Meeting, the International Waters learning platform, IW:LEARN, for the first time, invited river basin organizations to participate with their related LME’s in a world café dialogue. This has resulted in improved source-to-sea collaboration.
