France looks pretty good compared to some other places like the Netherlands, Belgium, Denmark , Germany and England
or further south, Egypt , Iraq and Qatar
or Bangladesh, Pakistan or China
or , perhaps closer to home , the Mississippi valley and the eastern coast of the USA
Perhaps I should have been a bit clearer in my phrasing, France is not self sufficient in food like they were a hundred years ago. They import from all over the world market just like everyone else. If sea levels start rising significantly a lot of the world food supply is going to disappear, in your example Egypt will lose the current delta, where they grow most of their wheat, and will have to wait for the Nile river silt to rebuild a new higher delta before they can grow it again. The same thing is true of India where much of their best crop land is delta deposits of silt on the Indian Ocean. In the USA the silt deposits are used to grow most of the rice crop growing in the USA, which is actually a significant source of calories people here tend to overlook.
Then when you add in refugees from Bangladesh or The Netherlands or Louisiana that currently live at or below sea levels who will be displaced by any significant sea level rise and Paris will be in a world of hurt a very long time before sea levels would actually encroach on the city limits.
