Abstract
La création d’une réserve marine au nord de la Martinique, dans la commune du Prêcheur, a donné lieu à une évaluation de la valeur économique des écosystèmes marins et côtiers (EMC) de la zone d'étude. La valeur économique totale (VET) obtenue est de l’ordre de 58 millions d’euros, soit près de 12 millions d’euros par km2. Cette valeur correspond à la somme des valeurs liées aux différents usages directs (pêche, excursion et plongée encadrée, pour l'essentiel), soit près de 3 millions d'euros, aux usages indirects provenant des services écologiques (protection côtière, séquestration carbone, production de biomasse et épuration des eaux, pour l'essentiel), soit environ 200 000 euros, et, à la valeur de non-usage associée à l'existence des écosystèmes et à la transmission de ce patrimoine naturel aux générations futures en dehors d'un quelconque usage présent et futur, soit près de 55 millions d'euros. La création de la réserve devrait engendrer une augmentation de cette valeur en améliorant les services écologiques et les usages ludiques.

The creation of a marine reserve in the noth-western part of Martinique, located in the area of Prêcheur, has led to an economic valuation of marine and coastal ecosystems. The total economic value (TEV) has been estimated to about 58 million Euros annually, almost 12 million Euros by km². This value stands for the sum of values associated to: i) direct uses (fishing, diving, beach leisure, etc.) for almost 3 million Euros; ii) indirect uses originating from ecological services (water treatment and nutrient cycling, biomass productivity, carbon sequestration) for 200,000 Euros; and iii) non-uses associated to the existence and bequest to next generation of the natural capital without any consideration of use for about 55 million Euros. The creation of the marine reserve should lead to an increase of this value through an enhancement of ecological services of ecosystems and the non-extractive uses such as tourism and marine leisure.
