This case study of the Bonaire Marine Park (BMP) in the Caribbean is a combined ecological and economic analysis. It has become increasingly obvious that, rather than selecting the extremes of strict preservation or unmanaged development, balanced use of marine resources for both economic and ecological functions is central to their sustainable management. This study estimates the benefits and costs associated with dive tourism, as well as the willingness-to-pay for park protection. The BMP study explicitly considers the link between the production of ecological and economic benefits, and identifies the limits to increasing use.
