Abstract
Sea level rise due to climate change is an ongoing process that will continue for centuries and millennia. In response to this, France is increasingly considering sea level rise in its coastal risks and land use policies. Here, we show that despite real progress in coastal adaptation policies made so far, major challenges remain. We report progress regarding the consideration of ongoing erosion and flooding during storms, in particular owing to an evolving national regulation increasingly supporting the implementation of a nationally defined integrated coastal zones management strategy. Yet, chronic flooding at high-tides in ports and cities expected to emerge in the 2030s, as well as permanent flooding and shoreline retreat projected to take place within centuries without major protection works remain largely unaddressed to date. Major questions remain in terms of adaptation finance and other measures supporting coastal adaptation such as climate services. Finally, the topic of coastal adaptation lacks connections with the broader context of transformations needed to address climate change, biodiversity losses, and meet the sustainable development goals. The case of France exemplifies how an evolving adaptation planning, which takes decades to implement, can ultimately fall short of effectively addressing major transformational challenges and achieving climate resilient development. We argue that a clear and transparent public debate on climate change and the nature of solutions could help bridge the gap between ongoing adaptation and transformative measures in line with the challenges.
期刊介绍:
Rendiconti is the interdisciplinary scientific journal of the Accademia dei Lincei, the Italian National Academy, situated in Rome, which publishes original articles in the fi elds of geosciences, envi ronmental sciences, and biological and biomedi cal sciences. Particular interest is accorded to papers dealing with modern trends in the natural sciences, with interdisciplinary relationships and with the roots and historical development of these disciplines.
