The GEF Biennial International Waters Conference (IWC) is the signature learning event for the GEF International Waters portfolio of projects and partners. IWCs bring together around 300 project managers, technical experts, participating country representatives, NGOs, private sector and GEF Agency staff from more than 700 ongoing projects in 70 countries. The IWC's principle objective is to facilitate cross-sectoral and portfolio-wide learning and experience-sharing.
