Forecasts agree in indicating that 75% of the world's population will live less than 60 km from the coast within 20 years, compared to 60% currently, stressed André Ozer, professor-researcher at the University of Liège (Belgium) and one of the great specialists in remote sensing and geomorphology, estimating that urban, tourist and industrial pressures on the coastlines have become a primary cause of beach retreat.The global climate changes currently observed have as a consequence a universal rise in sea level estimated, for stable zones of the globe, at 13 cm per century since 1870, noting that this rate is constantly increasing, insofar as the IPCC (Intergovernmental Panel on Climate Change) estimates it at a speed of 18 cm per century since 1961 and 31 cm per century since 1993. The consequences of this sea level rise on the coastlines lead to various environmental problems, among ot…
