A new study, part of the “National Roadmap for Adaptation 2100”, presents alarming forecasts for the future of Portugal's coastline. If no action is taken, it predicts the coastline could retreat by up to 200 metres at Costa Nova and 100 metres at Praia de Faro by the end of the century.
In extreme scenarios, this retreat could reach 400 metres at Costa Nova, or even breach the island of Faro, according to Expresso. The phenomenon is being worsened by a shortage of sediment—largely due to river dams—as well as the increasing frequency and intensity of storms and the rising average sea level caused by climate change.
Physicist Pedro Matos Soares, who leads the research, stresses the urgent need to integrate climate forecasts into Portugal’s coastal planning, invest in active protection measures, and consider strategies such as the fair relocation of affected communities.
He also criticises construction in high-risk areas based on so-called “acquired rights”, warning that planning should be proactive rather than reactive.
