Marine Protected Areas

Marine Protected Areas (MPAs) are designated zones in coastal and marine environments where human activities are regulated to conserve biodiversity and ecosystem services. In the Caribbean, MPAs help safeguard coral reefs, mangroves, and seagrass beds—natural barriers that reduce storm surge impacts, coastal erosion, and flooding. These ecosystems also store carbon, making MPAs relevant for both climate adaptation and mitigation. Healthy marine habitats are more resilient to stressors like rising sea temperatures and ocean acidification, which are major threats to Small Island Developing States (SIDS). For islands such as Curaçao, Aruba, and St. Martin, MPAs are critical because tourism and fisheries depend on marine health. Studies show that continued reef degradation could cut tourism revenues and fisheries income by up to 50%, severely impacting local economies.

Possible measures increase the efficiency of MPA's include:

  • Create no-fishing zones to allow fish populations to recover. 
  • Expand and link Marine Protected Areas across national waters and the wider Caribbean to form connected networks. 
  • Strengthen enforcement so MPAs are effective and not just “paper parks.” 
  • Update park fees to reflect the true value of reefs and marine ecosystems. 
  • Run awareness campaigns for both tourists and local communities to highlight the importance of MPAs. 
  • Collaborate with stakeholders—including fishers, tourism operators, and local communities—to ensure fair and inclusive governance. 
  • Carry out regular monitoring and biodiversity surveys to track ecosystem health. 
  • Integrate climate adaptation and mitigation goals into all conservation plans. 
  • Invest in research and monitoring to understand how climate change affects MPAs and improve management strategies.

Feasibility & Local Applicability

Expanding MPAs or improving enforcement is feasible but requires strong governance, funding, and stakeholder cooperation. Challenges include balancing conservation with economic activities like tourism and coastal development. Enforcement capacity and monitoring technology remain limited, and sustainable financing mechanisms are still underdeveloped. Regional collaboration and integration into national climate strategies can improve success. 

Co-benefits

MPAs provide multiple benefits beyond climate resilience. They support fish stock recovery, which benefits local fishers and food security. They enhance tourism appeal by maintaining healthy reefs and clear waters, generating income and jobs. MPAs also protect biodiversity and cultural heritage, contributing to sustainable development goals in many ways. Well-managed MPAs have been linked to higher household incomes and improved well-being in nearby communities due to spillover effects from fish recovery and tourism growth.

Equity & Vulnerability Considerations

Inclusive governance is essential. Fishing communities and small businesses should participate in zoning decisions and benefit-sharing arrangements. Temporary restrictions, such as no-take zones, may require compensation or alternative livelihood programs. Community engagement in monitoring and restoration can build trust and ownership. Equity measures ensure that conservation does not disproportionately burden vulnerable groups while allowing them to share in economic and ecological gains. 

Costs

Medium – High | Costs vary by size and management intensity. Establishment costs include legal designation, infrastructure, and stakeholder consultations. Recurrent costs involve enforcement, monitoring, and community outreach. Estimates for Caribbean MPAs suggest annual management costs range from $200 to $1,000 per km², depending on enforcement and technology needs. Opportunity costs—such as foregone fishing or development—must also be considered, but these are often offset by long-term economic benefits from tourism and fisheries recovery.
