Caribbean

To assist the process of extending the Bahamas National Protected Area System, The Nature Conservancy funded a study to map coral-reef fisheries at a national scale.  The key aims of this work were to model and map fishing impact, model and map the current fish standing stock, and assess the potential benefit of conservation and management measures, such as the potential standing stock on a reef following the cessation of fishing. The maps generated by this project represent the first spatially explicit, continuous maps of fishing impact and current and potential standing stock for The Bahamas. This project provides important data layers for use in Marxan to identify key locations for new marine reserves. Read the final report here. View interactive maps from this project here.

As part of the Caribbean Biological Corridor project that aimed to further understand regional connections throughout the Caribbean Basin, the team developed a tool that allows multi-sector stakeholders to examine ecological and socioeconomic factors for prioritizing restoration efforts, providing a regional platform to consider important coral reef larvae connectivity indicators (such as the amount of estimated larvae contributed and the ability to self-recruit) as well as integrating high priority nodes that are important for maintaining connectivity health (read the article here). In addition, users can explore two ecosystem service models that reefs provide:

1. Coastal vulnerability- highlights the protective services offered by coastal habitats to coastal populations. This information can be used to identify regions of greater risk to coastal hazards (such as erosion and flooding), which can in turn better inform development strategies and permitting.
2. Recreation and tourism – predicts tourist visitation and recreation rates, based photo-user-days from geotagged photos in the flicker database, highlighting patterns of tourism and recreational use around coral reefs.

Ocean resources in the Caribbean have the potential to make a much greater contribution to poverty reduction and shared prosperity for the region’s growing population of 40 million than they do currently, and to increase the resilience of people to climate change. The Caribbean region has been at the forefront of a movement towards the development of the blue economy and is home to a growing number of developing states that share the Caribbean Sea and have embraced the concept as the centerpiece of future growth strategies.

Given the value of the region’s marine space and its resources, with support from the Global Environment Facility (GEF), the Organisation of Eastern Caribbean States (OECS) Commission, in partnership with the World Bank, completed the Caribbean Regional Oceanscape Project (CROP) in 2021. The purpose of the CROP was to improve systems and put relevant structures in place in an effort to foster a Blue Economy and to promote greater consideration of the ecosystem functions and services, which the ocean provides for member states.

Under this project, The Nature Conservancy used the Mapping Ocean Wealth approach to develop ecosystem service models at the scale of the Eastern Caribbean in support of the Caribbean Regional Oceanscape Project.  We refined and adapted existing coral reef tourism and fisheries models, and developed novel methodologies to characterize recreational fishing and wildlife tourism in participating Eastern Caribbean countries (Dominica, Grenada, St. Kitts and Nevis, Saint. Lucia, and St. Vincent and the Grenadines). These data will support these countries in ongoing and future marine spatial planning through the direct provision of spatially explicit information on their ecosystem service values, particularly relating to fisheries and nature-based tourism.

Since 2008, TNC has been working with the Cayman Islands Department of Environment (DOE) on MPA design and assessment.  Partnering with local government and stakeholders, TNC helped to design a new MPA Network which expands the current MPA system from 16.7% to 50%, or 7,717 acres to 26,542 acres. The new design incorporated the latest scientific concepts on MPA design, based on the TNC Reef Resilience Guidance, connectivity of maximizing fish spillover for fisheries benefits.  TNC also took part in a scientific assessment of reef resilience within and outside MPAs in the Cayman Islands using the Healthy Reefs initiatives. TNC trained DOE employees on how to use Marxan to inform MPA network design based on extensive engagement with local government and stakeholders, and providing scientific and technical expertise during the assessment reef resilience in the MPA network. To support monitoring efforts, a smart-phone app was developed for enforcement and for public interaction on rules, regulations and sustainable seafood options related to MPAs. To assist with prioritizing areas for coral reef restoration, TNC created a coral reef restoration explorer that permits users to analyze and overlay a variety of ecosystem service benefits provided by coral reefs, such as coastal protection, reduction of exposure, and recreation and tourism.

As Cuba seeks to develop in a sustainable manner, TNC is working with the Cuban government to assess and train employees in modeling the storm and flood protection benefits that coral reefs and mangroves provide. Ecosystem service information is being integrated into future MPA expansion and management plans within the national protected areas network. Using InVEST, qualitative estimates of coastal exposure and the role of habitats during storm events are being analyzed. By combining these results with population information, the model identifies where coastal communities are most vulnerable to wave energy and storm surge, and where coral reefs and mangroves provide a significant role in reducing impacts to these communities. Based on model output, recommendations are being made to include these key habitats within the national system of protected areas, permitting decision makers to more effectively concentrate restoration and protection efforts in areas where people are most likely to benefit from nature’s services.

A study by The Nature Conservancy and JetBlue shows the powerful value of coral reef ecosystems to both the tourism industry and to the to the economic success and stability of the region. This study reveals and quantifies the extraordinary value that coral reefs contribute to the Caribbean economy through reef-adjacent activities alone, and the direct connection that reefs have on tourism across the region. The study found that reef-associated tourism is estimated at more than $7.9 billion annually from over 11 million visitors. This accounts for 23 percent of all tourism spending and is equivalent to more than 10 percent of the region’s gross domestic product. This new study, also supported by Microsoft and the World Travel & Tourism Council, reveals and quantifies the significant value that coral reefs contribute to Caribbean economy through reef-adjacent activities such as sailing, diving and snorkeling beach-based activities and the direct connection that reefs have on tourism. A project summary can be found here, while the full report can be found here.

Resilient Islands is a four-year initiative to protect islands against the impacts of climate change by promoting the use of coastal habitats to reduce risks, and by helping governments, partners and communities implement sustainable development plans that prioritize nature.

The Nature Conservancy and the International Federation of the Red Cross and Red Crescent Societies (IFRC) are developing an adaptation toolkit to promote better decision-making and resilience through disaster management that integrates nature-based solutions. The project will also implement innovative nature-based interventions within coastal communities in the Dominican Republic, Grenada and Jamaica. Learn more here. 

We used the InVEST Coastal Vulnerability and Coastal Protection models to map and quantify exposure reduction and protection provided by coastal ecosystems in USVI. TNC is working with the USVI Department of Planning and Natural Resources and Coastal Zone Management to model conservation and development scenarios that enable decision makers to assess tradeoffs with alternative management choices and identify where investment in natural capital enhance human development and conservation. The Coastal Vulnerability and Coastal Protection models identify where coastal habitats are most likely to 1) reduce exposure to erosion and flooding from storms and future sea levels and 2) protect vulnerable people and property.  Model outputs are being used to evaluate the ability of nearshore habitats to reduce nearshore wave energy/erosion and mitigate vulnerability – allowing users to explore the potential impacts of management actions (such as the removal or restoration of nearshore habitat) on vulnerability.
