In the heart of the Indian Ocean, L’Ile de la Réunion is hit hard by climate change. Cyclones are increasingly common from April to November. Natural catastrophes plunge the population into extreme situations: floods, landslides and torrential rains follow one another. Rising ocean levels accelerate coastal alteration. The inhabitants of this overseas department are mobilizing in order to move towards an ecological transition. By 2022, hot springs could generate energy through geothermal energy. The sunshine allows the installation of many photovoltaic parks. Together, permaculture and fish farming are developing as well.
