This joint World Bank/GFDRR/OECD report is the first attempt at quantifying the flow and patterns of concessional finance in support of climate and disaster resilience in SIDS. The report, coordinated in GFDRR by the SISRI team, aims to inform policy and decision makers, in both SIDS recipient governments as well as among funding providers, and promote a more effective provision and use of financing for resilience funds.
