The Mediterranean is the most densely populated closed sea in the world
The total population of the Mediterranean countries grew from 276 million in 1970 to 512 million in 2018. It is predicted to grow by an additional 182 million inhabitants by 2050. In 2019, the percentage of built-up areas has reached an astounding rate.
The coastal zone is becoming increasingly populated and built up and concentrates most of the major cities, many transport routes (roads, ports, airports), as well as industrial and energy infrastructure. This concentration is intensifying year after year and generates more pollution and disturbance leading to environmental degradation and increased risks for coastal populations and infrastructure. Besides these pressures in coastal areas, natural hazards such as storms and flooding add to the overall challenge. As their frequency, occurrence and intensity increase, they pose a real threat and weaken the resilience of ecosystems, human populations and coastal infrastructure. In this context of increasing environmental changes, including climate change threats, a strong landscape and ecosystem protection policies are needed.
PAP/RAC has proposed some new indicators aiming to reveal the sustainability of the spatial development along the Mediterranean coast. Some of these indicators have been proposed to Mediterranean countries for monitoring of the good environmental status of the Mediterranean Sea, while some are proposed to regional and national government in the framework of the Coastal Plans. These indicators also measure the level of fragmentation of the coastal ecosystems and therefore, coastal ecosystems health. Several indicators have been proposed for monitoring to the Mediterranean countries on coastal ecosystems and landscapes that reveal the sustainability of the spatial development along the Mediterranean coast
