The sea level has always been changing. While we are facing the sea level rise and wondering how much it will cost us, it seems interesting to know which impacts it had on human activities in the past. I found some articles which bring some very interesting and surprising arguments.
I learnt that sea level rise played an important role in the important period of migration. Indeed, Turney and Brown (2007) reports that the abrupt sea level rise of 1.4 meter around 8350 BP 8230 BP and explains the salt intrusions in the black sea and thereby the migrations of the Neolithic people to Europe, spreading the neolithic across Europe.
Moreover, the colonization of the small pacific island by humans had often seemed mysterious. Why have people migrated from island to island sometimes separated from very long distances? Nunn (2007) States that the sea level changes had some very important impacts on these societies. Sea level rise was threatening the crops by erosion whereas sea level fall was dragging the water table down and undermining the yields. Thus the periods of rapid sea level changes have been followed by perilous migrations in the Pacific Islands.
At the time of globalization, innovations do not need massive migrations to be spread. At the opposite, innovations are spread to not let the massive migrations happen: the advanced countries sell and export their resilience to sea level rise ( Chu, 2013).
