This case study applies an ecosystem services framework to understand how human activities affect the flow of benefits, including models that quantify services provided by corals, mangroves, and seagrasses. This information is then used within an extensive engagement process to design a national spatial plan for Belize's coastal zone. This process makes Belize's coastal spatial plan the first of its kind.
Through iterations of modeling and stakeholder engagement, the authors developed a preferred plan, currently under formal consideration by the Belizean government. The results suggest that the preferred plan will lead to greater returns from coastal protection and tourism than outcomes from scenarios oriented toward achieving either conservation or development goals. The plan will also reduce impacts to coastal habitat and increase revenues from lobster fishing relative to current management. By accounting for spatial variation in the impacts of coastal and ocean activities on benefits that ecosystems provide to people, the models allowed stakeholders and policymakers to refine zones of human use. The final version of the preferred plan improved expected coastal protection by more than 25 percent and more than doubled the revenue from fishing, compared with earlier versions based on stakeholder preferences alone. Including outcomes in terms of ecosystem service supply and value allowed for explicit consideration of multiple benefits from oceans and coasts that typically are evaluated separately in management decisions.
