New paper on Economic motivation for raising coastal flood defenses in Europe

Extreme sea levels (ESLs) in Europe could rise by as much as one metre or more by the end of this century due to climate change. This poses significant challenges to safeguard coastal communities. Here we present a comprehensive analysis of economically efficient protection scenarios along Europe’s coastlines during the present century. We employ a probabilistic framework that integrates dynamic simulations of all ESL components and flood inundation, impact modelling and a cost-benefit analysis of raising dykes. We find that at least 83% of flood damages in Europe could be avoided by elevating dykes in an economically efficient way along 23.7%-32.1% of Europe’s coastline, specifically where high value conurbations exist. The European mean benefit to cost ratio of the investments varies from 8.3 to 14.9 while at country level this ranges between 1.6 and 34.3, with higher efficiencies for a scenario with high-end greenhouse gas emissions and strong socio-economic growth.

GCF-MESSAGE IN A CYBER-BOTTLE, #1/2020

In the flood of information and news, now another text from GCF?  Yes – because our cellphones and computers keep flashing up with news about the coronavirus pandemic, the global economic and social disruptions it is triggering, and about the climate crisis lurking in the background. The result: information overload, calling for a calm effort to develop the understanding needed for reorientation in a world that has suddenly changed.
