Abstract

Martinique has 55 km 2 of coral reefs, seagrass beds and 50 to 20 of mangroves. These three ecosystems produce goods and services whose value is estimated at some 250 million euros a year. Nearly 60% of this value is derived from direct uses associated with recreational activities (diving, excursion, seaside recreation) induced mainly by tourism and those related to fishing (professional and plaisancière). Ecosystem services (similar to indirect uses) such as coastal protection, absorption / carbon sequestration, biomass production of fish and water treatment are significant because their annual value amounts to 94 million € 38% of the total value. The value of respect to the non-use of the reefs, seagrass beds and mangroves (linked to the desire to pass an ecological heritage for the most part or to the satisfaction of knowing that the reefs are in good condition) results in a value creation of around 10 million € / year. Seagrass beds and mangroves contribute the most (per km 2) to value creation (respectively 2.16 million € / km 2, 1.87 million € / km 2 against 1.78 million € / km 2 for coral). They should therefore benefit from protection measures and especially valuation as well as coral reefs that are already the subject of special attention.
