Pillar 5 focuses on the intense and frequent seismic and hydrometeorological hazards faced by populations in overseas territories and intertropical regions: earthquakes, volcanic eruptions, tsunamis, gravitational instabilities, floods/marine flooding, and coastal erosion.

Overseas and intertropical areas present a set of geographical and societal specificities that require a deep understanding of local capacities for prevention, risk management, and resilience (insularity, diversity of cultural and historical practices, and social and political tensions). Innovative management strategies must therefore be developed and tested in terms of feasibility, acceptability, and inclusiveness, while accounting for the political and social status of these territories.

Challenges

  • Challenge 1. Identify new observables to study natural hazards and associated anthropogenic impacts at large spatial and temporal scales (e.g., long seismic and volcanic cycles, and cyclone cyclicity).
  • Challenge 2. Develop holistic and integrated models of complex processes that account for uncertainties in climate change projections.
  • Challenge 3. Develop integrated risk management strategies tailored to overseas and intertropical areas, able to address the consequences of extreme events and cascading events generating multiple risks (eruptions, instabilities, tsunamis, floods, etc.).
