Abstract
The Caribbean is one of the application case studies within the Horizon Europe PARATUS project. This region faces multiple hazards: tropical cyclones, seismic hazards, volcanism, tsunamis, and space weather events. These hazards can have complex interactions, also with man-made hazardous events, in space and time, which can have both compounding and cascading impacts. The disaster risk management organizations often lack the information and tools to account for the cross-sectoral impacts and dynamic nature of the risks involved. KNMI has developed a prototype of a multi-hazard dashboard for the Dutch Caribbean islands (Bonaire, Sint Eustatius and Saba, or BES). The dashboard can import KNMI geospatial datasets, but also external datasets in real-time and simultaneously shows information about weather models and satellite data as well as earthquakes and tsunami warnings. Impact chains have been co-created during the first stakeholder session of this application case study, held on St. Maarten in March 2023. The impact chain developed for the telecommunication sector serves as an example, because telecommunication is essential for disaster mitigation and relief. Climate change is affecting the Caribbean region already. KNMI examines possible future scenarios for societally-relevant variables like sea level rise, temperature and precipitation changes and tropical cyclones. The climate scenarios for selected islands will be developed further during PARATUS. They will feed into the PARATUS Platform, together with the impact chains.
