Evaluation of coastal squeeze and beach reduction and its consequences for the Caribbean island Martinique

Abstract

Based on a spatial model, the Martinique beaches and coastal wetlands are examined to identify the risks of coastal squeeze. In many cases coastal development prevents coasts from adapting by shifting landward. Also tourism infrastructure augments the vulnerability of beach reduction and mangrove squeeze. More than 70% of all Martinique beaches and 29% of mangrove forests are highly endangered by coastal squeeze if sea level rises. The majority of coastal constructions and especially tourist hotels are built at heights between 1 and 10 m above the present sea level and therefore also within the zone at risk to flooding and erosion. Spatial analysis based on a conducted GIS model is carried out that evaluates the tourist destinations most vulnerable to the impacts of sea level rise. If sea level rises and beach reduction becomes an increasing problem the attractiveness of Martinique beaches as tourist destination is likely to decline.Caribbean, Lesser Antilles, Regional Planning, GIS, Climate Change, Coastal Change, Erosion, Inundation
