Resumo
The littoral fringe is a one of the natural environments more highly transformed by human activities, either direct or indirectly. The 40% of world population lives at the coastal area (40% in Spain), so any alteration of this environment becomes seriously risky. Since the second half of 20th century, sedimentary balance present a progressively higher negative trend mainly due to human activities, with a consequent increasing erosion and coastal retreat, in many cases reported as sea level rise. A wide trend to dramatize has arisen these last decades about what is going to happen with the littoral all over the world, with a wide flooding causing the disappearance of all terrains by the sea. Our littoral is ill, but if we want to know which the real illness is and how should we proceed, first we have to know the real problem in each considered site. We should analyse the sedimentary balance for each location in danger, the causes of the disequilibria, the sea level trend during in a near past, and above all, the adaptation capacity to a sea level rise. We should know before giving a diagnostic.
