Conservation Ecology 7(3): 10. [online] URL: http://www.consecol.org/vol7/iss3/art10 Report Understanding Complex Human Ecosystems: The Case of Ecotourism on Bonaire Thomas Abel ABSTRACT. It is suggested that ecotourism development on the island of Bonaire can be productively understood as a perturbation of a complex human ecosystem. Inputs associated with ecotourism have fueled transformations of the island ecology and sociocultural system. The results of this study indicate that Bonaire's social and economic hierarchy is approaching a new, stable systems state following a 50-yr transition begun by government and industry that stabilized with the appearance of ecotourism development and population growth. Ecotourism can be understood to have "filled in" the middle of the production hierarchy of Bonaire. Interpreted from this perspective, population growth has completed the transformation by expanding into production niches at smaller scales in the production hierarchy. Both a consequence and a cause, ecotourism has transformed the island's social structure and demography. The theory and methods applied in this case study of interdisciplinary research in the field of human ecosystems are also presented. INTRODUCTION receiver value used in conventional economics. Emergy is the "energy memory" (emergy) of all prior In this paper, I explore the impacts of ecotourism work contributed by ecosystems, global processes, and development on the socioeconomic structure of a small human systems. Unlike traditional energy currencies island in the Caribbean. Understanding the effects of of calories or joules, emergy values account for the an unplanned intervention or perturbation of whole chain or web of processes at different temporal and systems is an appropriate subject of study for the spatial scales that contributed to the production of the interdisciplinary science of complex systems as service or product. Emergy therefore belongs within advocated by Holling (1998). This paper presents the the emerging field of complex-systems science that results of an interdisciplinary social and ecological studies multiscaled self-organizing systems. As a study (Abel 2000) of whole-systems transformations single currency, emergy can be used to compare brought about by an exceedingly popular formula for dissimilar natural resources and ecosystem objects, as economic development, namely, ecotourism. Although well as social and cultural capital. ecotourism development on the island of Bonaire, as elsewhere, aims to minimize negative impacts on local The case study that concludes this paper focuses on populations and environments, I expected that the transformations of the socioeconomic structure of many new inputs to the region beyond the narrow Bonaire. The principles of hierarchy and self- tourism sector would bring changes to the economy organization used in studies of complex systems are and ecology of the island. Those transformations can applied to recent and historical data from Bonaire to be understood and evaluated from the perspective of produce some aggregate measurements of change. The complex systems. results indicate that the preconditions for the development of ecotourism on Bonaire were created To understand the impacts of tourism, the study used a by government spending, the presence of nearby form of ecological economics known as "emergy refineries, and the arrival of some small export accounting." A full explanation of emergy accounting industries, a setting from which ecotourism "took off" can be found in Odum (1996). In brief, emergy in the mid 1980s. It is argued here that ecotourism accounting evaluates the energy contributions to a represented a "filling in" of the middle scales in a service or product, of natural or human design, rather production hierarchy. By doing this, ecotourism than the amount it sells for in the marketplace. It is amplified production both at smaller and larger scales, thus a donor value, which contrasts with the type of reaching a new and relatively stable regime in a 50-yr University of Florida Conservation Ecology 7(3): 10. http://www.consecol.org/vol7/iss3/art10 self-organized transition.

Simultaneously, systems diagrams can lead the human symbolic systems of cultural models, which directly to the production of computer simulations possess a structure and dynamics of their own.

This diagram also includes the mean human symbolic behavior alone.
