Economic analysis of Indonesian coral reefs (Inglês)

Coral reefs are a precious resource, with a variety of functions, such as subsistence fishery, coastal protection, tourism, and biodiversity. The Indonesian reefs are being rapidly destroyed by a number of different threats. The private benefits to individuals involved in these destructive practices are often considerable. However, the costs to society are much larger, up to a factor of 50 higher in the case of blast fishing in tourist areas. The divergence between private benefits and social costs imply a highly inefficient outcome that calls for decisive government action to stop these threats. This study integrates a social-welfare based economic analysis and a stakeholder analysis with a discussion on options for rational coral reef management. The paper first discusses, in Chapter 2, the most important functions of coral reef. It also estimates the value of some of these functions. In Chapter 3, the five major threats (poison fishing, blasting fishing, sedimentation/pollution, coral mining, and overfishing) are analyzed and an economic and stakeholder analysis is presented for each of the threats. Finally, Chapter 4 discusses the management options for each of the threats. Appendix also gives a short annotated bibliography of literature on man-made coral reef destruction.
