Undertaken to help societies make better-informed choices, the economic research shows a single hectare of coral reef, for example, provides annual services to humans valued at US $130,000 on average, rising to as much as $1.2 million.
The work provides insights into the worth of ecosystems in human economic terms, says economist Pavan Sukhdev of UNEP, head of a Cambridge, England-based project called The Economics of Ecosystems and Biodiversity (TEEB). Based on analysis of more than 80 coral reef valuation studies, the worth of services per hectare of coral reef breaks down as follows:
- Food, raw materials, ornamental resources: average $1,100 (up to $6,000);
- Climate regulation, moderation of extreme events, waste treatment / water purification, biological control: average $26,000 (up to $35,000);
- Cultural services (eg. recreation / tourism): average $88,700 (up to $1.1 million)
- Maintenance of genetic diversity: average $13,500 (up to $57,000)
