Small island states face some of the greatest vulnerabilities of any nations due to climate change and natural disasters—but the threats can be reduced through adequate investment, technical expertise and hands-on support. Through its Small Island States Resilience Initiative (SISRI), GFDRR is helping step up the rate of progress to safeguard these unique environments from climate impacts such as sea-level rise, storm events and droughts. SISRI is providing technical support, helping maintain a community of practice, and helping island nations harness predictable and long-term funding to ensure their resilience.
