| The mean temperature on the planet is increasing. The rate of this increase appears to be accelerating and is at present approximately 2 degrees per century. 1998 was the warmest year since temperature recordings started some 150 years ago. Similarly the 1990s was the warmest decade. In addition, 1997 and 1998 saw the strongest El Niño ever recorded. As a consequence of this, very high water temperatures were observed in many parts of the oceans, particularly in the tropical areas. Due to the high water temperatures, the corals over much of the world bleached and subsequently died. In 1997–98, massive mortality occurred particularly among corals of the Indian Ocean. The reefs of Sri Lanka, Maldives, India, Kenya, Tanzania, and Seychelles were particularly... |

| Coral reefs are a vital resource to many areas of the Indian Ocean. Coastal populations are continuously increasing (Table 1) and relying on this resource as the basis of the economy. Across the region, the two common socio-economic reef based activities are fisheries and tourism. For local subsistence fishermen, reef fisheries often represent their only livelihood. Degradation of coral reefs will first impact the reef fishery and subsequently, the local fishing community. Tourism also is often heavily dependent on coral reefs as the main attraction. |

| Coral reef ecosystems provide many functions, services and goods to coastal populations, especially in the developing world. A variety of anthropogenic practices threatens reef health and therefore jeopardises the benefits flowing from these services and goods. These threats range from local pollution, sedimentation, destructive fishing practices and coral mining to global issues like coral bleaching. Economic valuation can help to shed light to the importance of the services and goods by ‘getting some of the numbers on the table’. Valuation techniques are discussed and a summary of economic studies on coral reefs is presented. The concepts of Total Economic Value and Cost Benefit Analysis are used to illustrate the valuation of marine protected areas... |
