Tonga is one of the most disaster-prone countries in the world, ranking 2nd of 181 countries on the World Disaster Risk Index. To better understand and prepare for disaster risks and the impacts of climate change, the Government of Tonga and the Asian Development Bank commissioned a Multi Hazard Climate and Disaster Risk Assessment in 2020 that analyzed thousands of buildings, roads, power and water assets in the island of Tongatapu. A risk index was developed from the assessment, which showed areas in Tongatapu that are at high risk to the impacts of climate change and will be subject to frequent or permanent flooding. The report also showed relatively safe areas that can be developed into resilient communities.
