To access the final edited and published work see https://doi.org/10.5209/aguc.72979Uno de los efectos más visibles del Cambio Climático es la subida del nivel del mar por el derretimiento de las masas de hielo terrestre. Para calcular la vulnerabilidad costera de la Manga del Mar Menor por la subida del nivel del mar, se ha aplicado el Índice de Vulnerabilidad Costera utilizando las variables geomorfología, pendiente de la costa, cambios en el nivel del mar, erosión costera, rango mareal, oleaje y una variable ambiental. El resultado refleja que tramos de playas de arena y las estructuras artificiales presentan mayor vulnerabilidad a los riesgos climáticos que aquellos tramos rocosos, por lo que se considera necesario la adecuación de sistemas duna-playa con vegetación natural bien conservada que constituyan una barrera frente a la energía de los temporales.- One of the most visible effects of Climate Change is the rise of sea levels by melting land ice masses. To calculate the coastal vulnerability of the Lower Sea Sleeve by sea level rise, the Coastal Vulnerability Index has been applied using geomorphology, coastal slope, sea level changes, coastal erosion, tidal range, swell and an environmental variable. The result reflects that stretches of sandy beaches and artificial structures are more vulnerable to climate risks than those rocky sections, so it is considered necessary to adapt dune-beach systems with natural vegetation well preserved that constitute a barrier to the energy of the storms.- L'un des effets les plus visibles du changement climatique est l'élévation du niveau de la mer due à la fonte des masses de glace terrestre. Pour calculer la vulnérabilité côtière de Manga del Mar Menor en raison de l'élévation du niveau de la mer, l'indice de vulnérabilité côtière a été appliqué en utilisant les variables de géomorphologie, la pente de la côte, les changements du niveau de la mer, l'érosion côtière, l'amplitude des marées, vagues et une variable environnementale. Le résultat reflète que les étendues de plages de sable et les structures artificielles sont plus vulnérables aux risques climatiques que ces étendues rocheuses, il est donc jugé nécessaire d'adapter les systèmes de dunes-plages avec une végétation naturelle bien préservée qui constitue une barrière contre la l'énergie des tempêtes

The main objectives are, among others, to stop the erosion of the dunes in front of a 500 m long beach and to expand the breeding habitat of aquatic birds. Between the dune and the beach, a barrier was placed to protect the dune from the effects of storms. The dunes were fenced, placed with sand traps and revegetation was carried out with native species in the most degraded areas. Within the salt pans, 1800 m of new sandy dikes were built to separate the salt ponds. The results have been the recovery of the dune ecosystem and the increase in the population of nesting aquatic birds and other species, as well as an increase in the quality and production of salt
