Description Complete
Cette évaluation complète examine la valeur économique des services écosystémiques fournis par les mangroves et récifs coralliens de la baie de Caracol, dans le nord-est d'Haïti. Utilisant la méthode de transfert de valeur écosystémique, l'étude estime que les mangroves contribuent 105,2 millions de dollars US et les récifs coralliens 4,5 millions de dollars US annuellement, totalisant 109,7 millions de dollars US en services écosystémiques. Le rapport souligne qu'Haïti reste la seule nation caribéenne sans aires marines gérées malgré plus de 1 771km de côtes.
L'étude a été menée pour l'Organisation des États américains et le Réseau inter-américain d'information sur la biodiversité dans le cadre du programme ReefFix, une initiative de gestion intégrée des zones côtières. En raison du manque de données socio-économiques et halieutiques fiables, la méthodologie s'est concentrée sur les calculs de transfert de valeur plutôt que sur une analyse économique complète. L'évaluation couvre 5 261 hectares de mangroves et 901 hectares de récifs coralliens dans la zone cible.
Le rapport incorpore les conclusions clés de l'étude 'Récifs en péril' de l'Institut des ressources mondiales, qui a identifié que près des deux tiers des récifs coralliens caribéens font face à des menaces d'activités humaines, incluant le développement côtier, la pollution, la surpêche et le changement climatique. Il souligne que la gestion inefficace des aires protégées existantes aggrave ces menaces, avec seulement 6% des aires marines protégées caribéennes classées comme efficacement gérées.
Le document conclut avec des recommandations pour établir la baie de Caracol comme première aire marine protégée d'Haïti, décrivant les considérations incluant la sélection du site, la détermination de la taille, les mécanismes d'application, la mise en œuvre du zonage, l'implication des parties prenantes et la planification de la durabilité.

In an attempt to estimate the monetary value of the services that ecosystems provide various methods of ecosystem valuation have been designed. Dollar-based valuation systems can include : travel cost, productivity, benefit transfer, and others. The Ecosystem Value Transfer (EVT)/Benefit Transfer Method (BTM) was used for this activity in which values which have already been estimated for similar ecosystems are extrapolated to the study site. The total estimates for ecosystem services for Caracol Bay are US$ 105,228,000 for mangroves and US$ 4,505,000 for coral reefs for a total estimated value for ecosystem services of US$ 109,733,000 (this total does not include ecosystem services provided by sea grass beds). In 2004 an assessment by the World Resources Institute arrived at certain key findings concerning Caribbean reefs. They include: 🕘 Nearly two-thirds of coral reefs in the Caribbean are threatened by human activities 🕘 An estimated one-third of Caribbean coral reefs are threatened by coastal development 🕘 Sediment and pollution from inland sources threaten about one-third of Caribbean coral reefs 🕘 Marine-based threats to coral reefs are widespread across the Caribbean 🕘 Overfishing threatens over 60 percent of Caribbean coral reefs 🕘 Diseases and rising sea temperatures threaten to damage coral reefs across the Caribbean region 🕘 Ineffective management of protected areas further threatens Caribbean coral reefs 🕘 The coastal communities and national economies of the Caribbean region are poised to sustain substantial economic losses if current trends in coral reef degradation continue With over 1,771km of coastline Haiti remains the only Caribbean nation without any type of coastal and marine managed area. Several areas of Haiti have been identified as areas of interest for the development of Coastal and Marine Protected Areas. The Caracol Bay of northeastern Haiti, as well as several other locations, contains very good potential for the development of coastal and marine protected areas. Caracol Bay contains a large expanse of mangroves as well as a fringing coral reef. There are several fishing communities harvesting marine resources in the bay, and the exploitation of mangroves occurs not only by these fishing communities but also by other communities located further inland. The methodology for the development of these areas as reserves/preserves should certainly include periods for public comment from concerned stakeholders and may end in, in the quickest of circumstances, a presidential decree (Arrêté), and otherwise a significantly longer process ending in parliamentary approval. Rapid Assessment of the Economic Value of Ecosystem Services Provided by Mangroves and Coral Reefs and Steps Recommended for the Creation of a Marine Protected Area Caracol, Haiti May, 2009 Page 2 Statement of Work Original: Compile necessary data on GIS, maps, ecosystems in and around the marine park, tourism, and fisheries data. Complete the 2 methodologies developed by the World Resources Institute: http://www.wri.org/map/marine-protected-areas-world, http://www.wri.org/project/reefscaribbean, http://www.wri.org/project/valuation-caribbean-reefs, and http://www.buccooreef.org/economic.html, and a third methodology called Ecosystem Value Transfer (EVT)/Benefit Transfer Method (BMT). Revised: Due to the lack of available information relating to socio-economic conditions, any type of tourism activities or revenue as well as a total lack of reliable information in regard to fisheries activities which would be required to accomplish the socio-economic portion of the original statement of work for Caracol Bay, it was revised to the following: 1. Provide the economic value analysis of coral reefs and mangroves using the values/ha/yr methodology for the proposed Caracol Marine park (EVT/BMT); 2. Design an action plan with the steps necessary to establish the area as a marine park. Introduction/Background ReefFix, supported by the government of Chile, is an Integrated Coastal Zone Management (ICZM) Coral Reef and Mangrove Restoration and Watershed Management Demonstration program that works with Small Island Developing States (SIDS) to restore and effectively manage coastal resources through the use and development of cost-effective techniques and economic validation of ecosystems (OAS/DSD). The World Resource Institute’s (WRI) economic valuation methodology provides a simple and replicable method for estimating the value of coral reefs and mangroves in the Caribbean. The methodology uses the concept of “ecosystem services” – the tangible benefits ecosystems provide which sustain and fulfill human life – as the basis for measurement. The approach looks primarily at the direct economic benefits provided by these resources; it does not attempt to calculate the Total Economic Value (TEV) of coral reefs and mangroves, which would include non-use values (for instance, the ‘existence value’ non-users place on the presence of the reef). The methodology focuses instead on three important ecosystem goods and services associated with coral reefs: fisheries, tourism, and shoreline protection services. These services comprise an integral part of many Caribbean economies. The methodology also offers guidance on estimating the wider (indirect) impact on the economy of these resources, the consumer surplus associated with their use, and the potential losses or gains in value associated with changes in ecosystem condition. (WRI, Economic Valuation of Coral Reefs, Methodology v2.1, October, 2007) Rapid Assessment of the Economic Value of Ecosystem Services Provided by Mangroves and Coral Reefs and Steps Recommended for the Creation of a Marine Protected Area Caracol, Haiti May, 2009 Page 3 Key findings from the Reefs at Risk in the Caribbean Report (Lauretta Burke, Jon Maidens and contributing authors: Mark Spalding, Philip Kramer, Edmund Green, Suzie Greenhalgh, Hillary Nobles, Jonathan Kool, September, 2004) include: • Nearly two-thirds of coral reefs in the Caribbean are threatened by human activities. Integrating threat levels from all sources considered in this analysis (coastal development, watershed-based sediment and pollution, marine based threats, and overfishing), the Reefs at Risk Threat Index identified about one-tenth of Caribbean coral reefs at very high levels of threat, one-third at high threat, one fifth at medium threat, and one-third at low threat. • An estimated one-third of Caribbean coral reefs are threatened by coastal development. This includes sewage discharge, urban runoff, construction, and tourist development. • Sediment and pollution from inland sources threaten about one-third of Caribbean coral reefs. Analysis of more than 3,000 watersheds across the region identified 20 percent of coral reefs at high threat and about 15 percent at medium threat from damage caused by increased sediment and pollution from agricultural lands and other land modification. • Marine-based threats to coral reefs are widespread across the Caribbean. Our indicator of marine-based damage and pollution identified about 15 percent of Caribbean reefs as threatened by discharge of wastewater from cruise ships, tankers and yachts, leaks or spills from oil infrastructure, and damage from ship groundings and anchors. • Overfishing threatens over 60 percent of Caribbean coral reefs. Fishing above sustainable levels affects coral reefs by altering the ecological balance of the reef. The removal of herbivorous fish, which consume algae, facilitates algal overgrowth of corals. Declines in coral cover and increases in algal cover have been observed across the region. This analysis identified about one-third of Caribbean reefs at high threat from overfishing pressure and about 30 percent at medium threat. • Diseases and rising sea temperatures threaten to damage coral reefs across the Caribbean region. Diseases have caused profound changes in Caribbean coral reefs in the past 30 years, with very few areas unscathed by disease, even reefs far removed from human influence. In addition, coral bleaching episodes-the most direct evidence of stress from global climate change on Caribbean marine biodiversity-are on the rise. • Ineffective management of protected areas further threatens Caribbean coral reefs. With the growth of tourism, fisheries, and other development in coral reef areas, marine protected areas (MPAs) are an important tool for safeguarding coral reefs. At present, over 285 MPAs have been declared across the Caribbean, but the level of protection afforded by MPAs varies considerably. The Reefs at Risk Project found only 6 percent of MPAs to be rated as effectively managed and 13 percent as having partially effective management. • The coastal communities and national economies of the Caribbean region are poised to sustain substantial economic losses if current trends in coral reef degradation continue. Coral reefs provide valuable goods and services to support local and national economies, and degradation of coral reefs can lead to significant economic losses, particularly in the coastal areas of developing countries, through loss of fishing livelihoods, malnutrition due to lack of protein, loss of tourism revenues, and increased Rapid Assessment of the Economic Value of Ecosystem Services Provided by Mangroves and Coral Reefs and Steps Recommended for the Creation of a Marine Protected Area Caracol, Haiti May, 2009 Page 4 coastal erosion. Analyses carried out by the Reefs at Risk project indicate that Caribbean coral reefs provide goods and services with an annual net economic value in 2000 estimated at between US$3.1 billion and US$4.6 billion from fisheries, dive tourism, and shoreline protection services.

Economic Valuation of Ecosystem Services Results The Ecosystem Value Transfer (EVT)/Benefit Transfer Method (BTM) was used to calculate the estimated value for ecosystem services. In this methodology values which have already been estimated for similar ecosystems are extrapolated to the study site. For this activity, a value of US$ 20,000 ($/Ha/yr) rate for mangroves, and US$ 5,000 ($/Ha/yr) rate for coral reefs is used based on a conservative low end average from a high of US$ 35,000 ($/Ha/yr) for mangroves and US$ 10,000 ($/Ha/yr) estimated by UNEP.
