Impact of sea-level rise in the azores islands. prospective analysis based on current projections

Abstract

Scientific projections point to an increase n the average sea-level rise from 0.25 to 2 m up to the end of this century. This increase will result in the disappearance of many beaches, low coastal areas and back retreat. Estimates indicate that more than 50 million people will be affected in the Pacific and Indian areas. The reduction of the available area and the greater pressure on natural resources, increased by the remoteness of other terrestrial areas can manifest the vulnerability in the Azores, which may affect islands or localities where the conditions of survival can become very complex. The most affected island will be São Miguel with 57.6% of the population at risk, but the analysis of the projections and impacts that may occur becomes important to define local action strategies. This analysis should be multidisciplinary, including the natural sciences and engineering, but also the social sciences, to help evaluate and dismiss incorrect perceptions of common sense.
