摘要

研究目的本研究旨在估算萨瓦纳-卡马圭群岛七个沿海泻湖的生态系统产品和服务的价值:采用一般和经验方法以及不同的研究技术得出结果。所研究的四个泻湖位于 Cayo Coco,其余位于 Cayo Sabinal:这项研究的方法框架具有动态、全面和系统的目的,包括两个步骤:全面描述泻湖及其生态系统的产品和服务,计算每个泻湖、每个地区和整个研究区域的这些产品和服务(实际和潜在)的价值(收入):结果:卡约科科和卡约萨比纳尔的沿海泻湖提供了多种多样的产品和服务(捕鱼、养蜂、 旅游),但由于各种因素,这些产品和服务的价值仍被低估。社会/管理方面的贡献:古巴当前的社会和经济环境以及监管和制度框架要求使用各种方法和技术对生态系统的产品和服务,特别是沿海生态系统的产品和服务进行经济估值,以适应沿海地区旅游业的快速发展。因此,这项研究的结果可以作为一个起点,将生态系统产品和服务的估值扩展到加勒比和古巴的其他沿海泻湖。

Valuation of ecosystem goods and services of seven Caribbean coastal lagoons
Objective: This study was to estimate the value of the ecosystem goods and services of seven coastal lagoons in the Sabana – Camagüey Archipelago. Methodology: Results were obtained using general and empirical methods, as well as different research techniques. Four of the lagoons studied are in Cayo Coco and the rest in Cayo Sabinal. Relevance: The methodological framework for this research had dynamic, comprehensive and systemic purposes with two steps: comprehensive characterization of the lagoons and their ecosystem goods and services and the calculation of the value (revenues) of these goods and services (real and potential) for each lagoon, for each territory and for the entire study area. Results: The coastal lagoons from Cayo Coco and Cayo Sabinal offer a wide variety of goods and services (fishing, beekeeping, tourism) still underestimated due to different factors. The direct and indirect use values of these lagoons represented more than 95 % (15 million Cuban pesos) of the total estimated value. Social / management contributions: the current social and economic context of Cuba and the regulatory and institutional frameworks require the use of methods and techniques for economic valuation of ecosystem goods and services, particularly those of coastal ecosystems, in correspondence with the fast development of tourism in coastal areas. For this reason, the results of this study could be a starting point to expand the valuation of ecosystem goods and service to other Caribbean and Cuban coastal lagoons.
