Fishing provides an important source of income and livelihood on the Caribbean Island of Bonaire, also many people fish for recreational purposes. A large part of the catch is composed of reef-dependent species, which rely on the health and productivity of local coral reefs. To assist decision-makers in understanding and managing these fragile ecosystems contributing to Bonairean well being the economic value of reef-dependent fisheries is determined. Furthermore, the spatial distribution of the economic value of the reef fisheries is revealed to help decision makers understand which areas of reef are most economically important from a fisheries perspectives.

By estimating the economic value of the reef fisheries, which consists of both recreational and commercial fishing, the total socio-economic value of reef fishing on Bonaire is estimated. Commercial fishing is valued using the ‘net factor income approach’. The recreational value of the reef fisheries is calculated using both the ‘choice modelling’ and the ‘market valuation’ method. The commercial and recreational values are combined to arrive at a total, annual reef-fisheries value for the Island of Bonaire. This aggregate value is then combined with spatial fisheries production data using ArcGIS to create a fisheries value map of Bonaire.

The reef-related total commercial fisheries are valued at almost $400,000 annually. The recreational fishery value is estimated at an economic value of almost $700,000 per annum. These calculations have been used to create an allocation function, which estimates the spatial distribution of the fisheries value along the coral reefs of Bonaire. This in turn can be used to support long-term decision-making for example regarding specific locations for coastal zone development and its impact on commercial and recreational fisheries. 

The global environment is in a relatively bad state and there is growing awareness of its importance to human wellbeing. This study aims to shed light on a corner of this importance. Although a corner its affects to human wellbeing is great. What if the entities one culturally identifies with should begin to deteriorate or very plausibly disappear? In the spirit of learning and providing innovation to current environmental policy practices, it is the objective of this study to determine the recreational and cultural value that the marine and terrestrial environment of Bonaire provides to its residents. The later in order to improve decision making on conservation efforts on the island by internalizing externalities in policies that affect the environment and its ecosystems. This was done through use of the environmental economics technique of choice modelling, which consists of a choice experiment as well as a supporting structured survey. Choice modelling determines the WTP (willingness to pay) to conserve nature. The results of this study suggest a yearly WTP by all households on Bonaire to improve the overall natural environments state from poor to moderate to be approximately $2,9 million USD and from poor to high as much as $3,9 million USD. However from the supporting background questions it was also concluded that a widely employed PES system (Payment for Ecosystem Services) would not succeed with- out learning taking place. There should be dialogue on the one hand and on account- ability (locals or tourists?) and on the other hand on the need for environmental management itself. In addition to this the most important perceived threats were found to be waste (solid and liquid) and coastal development. To sum up the study shed light on the tension that exists between tourism which residents economically depend on and the effect expanding tourism has on the nature of Bonaire. An impor- tant conclusion is that restriction of coastal and inland development is supported by locals as well as better waste management and goat management. Policy makers should take this document into account since it expresses the concerns and desires of the local population as regards to policies affecting the environment. 

To inform decision makers about the most effective strategies to protect the ecosystems of Bonaire, a full-scale valuation of all ecosystem services on the island of Bonaire has been undertaken by WIKCS and the VU University Amsterdam. The study addresses a wide range of ecosystems, ecosystem services and applies a multitude of economic valuation and evaluation tools. For budgetary reasons, a distinction has been made in terms of the ecosystem services covered by the studies between ecosystem services that are valued through primary research and ecosystems services that are addressed through secondary data analysis. This report summarises the ecosystem services that are valued on the basis of desk research or through key informant interviews. The quality of each sub-study varies, depending on the data availability to the subsequent researchers. This also implies that not each sub-study was able to actually generate a monetary value to be included in the Total Economic Value (TEV) estimate. Despite this caveat, the individual studies increase the understanding of the complex links between nature and society on Bonaire and are therefore worth presenting.

Art value

Artists are inspired by their surroundings. Such is also the case on Bonaire, where the natural scenery of the island stimulates artists to use components of nature in their work. Clearly, nature plays a crucial role in the production process of art on Bonaire. The demand of art consists of the thousands and thousands of tourists visiting the island, who are keen to bring home a piece of art to memorise the beauty of the island upon their return. Moreover, the beautiful photographs and books produced on Bonaire are distributed to clients across the world. Given the explicit demand and supply of art on Bonaire and its strong dependence on nature, the art sector on Bonaire plays an important role in the overall economy and provides an additional reason to manage nature well on the island. The value of the ecosystem service of artistic inspiration is valued at $460,000 annually.

Research value

Nature in Bonaire provides important services for research and education. The marine and terrestrial environment of Bonaire is subject for a large group of academics who conduct and publish innovative research based on these unique and easily accessible ecosystems. Without the presence of healthy ecosystems, Bonaire would not attract large numbers of researchers nor would Bonaire’s nature be a source of inspiration for many educational activities on the island and beyond. This sub-study made an inventory of all ecosystem related research expenditures funded by governmental and non-governmental organisations for Bonaire. In total a total research value was estimated between 1,240,000 USD and 1,485,000 USD in 2011.

Medical and pharmaceutical value

Medicinal plants play important roles in many traditional societies. The healing properties of herbal medicines have been recognized in many ancient cultures thousands of years ago. Besides these local benefits, biodiversity is important for the development of pharmaceutical treatments and drugs. The purpose of this sub-study is to economically value the benefits of species and ecosystem functions that are relevant for medicinal and pharmaceutical purposes. The study found that a large part of the population in Bonaire regularly collects and uses local herbs and other medicinal plants for medical treatment. Two-third of the inhabitants who were surveyed made use of local plants as an alternative to modern medicine or prescription drugs. Ultimately, a total annual medicinal and pharmaceutical value results of $688,788 of which more than half is comprised of the local value of medicinal plants.

Carbon sequestration

The ecosystem service of climate regulation deals mainly with greenhouse gas emissions and how ecosystems can mitigate such effects. Bonaire has six ecosystems that provide carbon-sequestering properties: salinas, dry forest, coral reefs, sea grass, mangroves and open ocean. The objectives of this sub-study is to (1) identify the ecosystems that are relevant to climate regulation in Bonaire with their functions and threats; (2) describe the different economic valuation methods suitable for climate regulation calculations; and (3) value the overall climate regulation potential of Bonaire. This desk study has made a rough attempt to estimate the carbon sequestration value of the main ecosystems of Bonaire. Based on carbon market prices at the time of research, this value was estimated at $290,000 per year.

Pollination by bats

The island of Bonaire is a fauna and flora rich and beautiful attraction in the Caribbean. By supporting fruit growth and aesthetic values, bats plays an important role in preserving high levels of biodiversity on Bonaire. This study made an attempt to give more insight in the importance pollination by bats for the island. Due to limited availability of data and time, the study will not generate an actual economic value of pollination. Yet, by describing the possible links between pollination and the economy of Bonaire, this study adds value and provides a solid foundation for an actual economic valuation study in the future. Despite of the lack of a concrete economic value, the evidence provide support the notion of conservation of the bats of Bonaire their natural habitat (i.e. caves). Both economic and cultural reasons have been identified to support this conclusion.

Coastal water quality

This paper attempts to examine the values of ecosystems in provisioning good water quality in Bonaire, Dutch Antilles. Bateman’s (2011) steps in ecosystem assessment and economic analysis are used as a framework to run this examination. Three ecosystems are identified that contributes to deliver services in question: mangroves, saliñas/salt marshes, and sea grasses. Based on their functions related to providing good water quality (filtering, water purification, and nutrient cycling) this report proposes three valuation methods: 1) replacement cost method for mangroves and saliñas; 2) Production function method for sea grasses. Benefit transfer also mentioned in the discourse to tackle the challenge of finding relevant data.

Amenity value

The fact that many people prefer natural over built environments is often manifested in house prices. Therefore various environmental conditions may have a significant impact on house prices. In Bonaire these include the view or proximity to water bodies, coral reefs and other healthy ecosystems. This study aims to estimate this so-called amenity value of nature on Bonaire. Through a hedonic pricing analysis, the hypothesis was tested whether property values are not only determined by conventional house and neighbourhood characteristics, but also affected by the presence and quality of Bonaire’s ecosystems. From this statistical analysis no strong significant impact of environmental variables onto the house prices has been detected and thus the hypothesis is rejected. This lack of evidence limits the possibility to calculate the amenity value. The cause of the poorly performing analysis is the limited data available on house sales on Bonaire.

Cultural value

The island of Bonaire has a precious though threatened nature and its culture is indistinguishable from nature. Yet, times are changing and so is the relationship between nature and society in Bonaire. Since the development of industrial times, less Bonairean practise agriculture, and less people are working in the nature. The objective of this study is to estimate the value of the cultural ecosystem services of the island of Bonaire. The scope of this sub-study is limited to four cultural values of ecosystems on Bonaire: (1) Recreational activities; (2) Subsistence and recreational fishing; (3) Kunukus; and (4) Cultural landscape. 

Bonairean ecosystems support touristic activities that depend on the quality of the natural environment, such as diving, snorkelling, kayaking, boating, enjoying beaches, and participating in land activities. The tourism sector is an industry with substantial size and financial contribution to the economy of Bonaire. However, the economic value of the contribution of nature to Bonaire’s tourism has never been quantified, nor have the most important aspects of Bonairean nature for tourism been identified. It is essential that the economic value of the ecosystem service to tourism and the dependence of tourism on Bonairean ecosystems while impacting these same ecosystems be determined in order to further assist policy-makers in understanding this crucial relationship and support them in wise long-term decision-making.

To determine the value of Bonairean ecosystems for the tourism industry a survey among tourists visiting Bonaire is conducted. This study estimates the average expenditures of these visitors, as well as their Willingness-To-Pay (WTP) for protection of Bonairean nature. The result of this survey also elucidates tourists’ perceived value of different aspects of Bonairean nature. The socio-economic value of the ecosystem services for tourism is combined with spatial data to determine which ecosystems are the most economically valuable with regards to tourism.

The expenditure by tourists on Bonaire is found to be around $125 million annually. An estimated welfare of around $50 million dollars is contributed by Bonaire’s nature to tourism. Stay-over tourists are found to contribute more to the tourism industry than cruise tourists, and marine ecosystems are found to be more economically significant than terrestrial ecosystems on the island. The high WTP of tourists for additional nature protection in Bonaire provides opportunities for the local government to increase the current user fees of visitors to Bonaire. 

IVM Institute for Environmental Studies 

The Institute for Environmental Studies (IVM) and Wolfs Company have composed this report in collaboration with the Joint Nature Conservation Committee (JNCC) to review the current status of sustainable finance in the Caribbean, including analyses of trends, obstacles, interventions and opportunities. Sustainable finance is the ability to secure a stable, sufficient and diverse mix of financial resources, and to allocate them in a timely manner and appropriate form, to cover the full costs of sustainable management of natural assets and biodiversity conservation. This ensures protected areas and other conservation programmes are managed effectively and efficiently, and guarantees the provision of goods and benefits to local stakeholders.

Sustainable finance is a critical component of nature conservation in the Caribbean, and this report defines the different mechanisms available to provide finance, alongside relevant examples and case studies in the Caribbean. The review of sustainable finance mechanisms and their applications is used to form recommendations and suggestions for improving financial sustainability in Caribbean Overseas Territories and other Caribbean islands. Though there is no ‘one size fits all’ or standard blueprint for optimal implementation of sustainable finance mechanisms, research suggests that community-centric approaches increase support and improve chances of stakeholder buy-in. Additionally, on a regional level there are many benefits to Caribbean islands working collaboratively and utilising an island network to pool resources and capacity. Finally, working on standards to monitor, measure and communicate impacts is an opportunity to improve investment in nature management. 

Healthy ecosystems such as coral reefs and mangroves are critical to Bonairean society. In the last decades, various local and global developments have resulted in serious threats to these fragile ecosystems of Bonaire, thereby jeopardizing the foundations of the island’s economy. Therefore, it is crucial to understand how nature contributes to Bonaire’s economy and its wellbeing in order to make well-founded decisions when managing the economy and nature of this beautiful tropical island. This research aims to determine the economic value of the main ecosystem services that are provided by the natural resources of Bonaire and their overall importance to society. The challenge of this project is to deliver sound scientific insights that will guide decision-making regarding the protection of Bonaire’s ecosystems and the management of the island’s economy.

By assigning economic values to the main ecosystem services of Bonaire, this research draws attention to the economic benefits of biodiversity and highlights the growing costs of biodiversity loss and ecosystem degradation. The study addresses the most relevant ecosystems and ecosystem services for Bonaire and applies a range of economic valuation and evaluation tools. By surveying over 1,500 persons, including tourists, fishermen, local residents, and citizens of the Netherlands, this study estimated the willingness of individuals to pay for the protection of Bonairean nature, as well as mechanisms (e.g. user fees) through which such payments would be transferred. Furthermore, a scenario analysis is conducted to inform decision makers about the most effective strategies to protect the ecosystems of Bonaire. This study intensively involved stakeholders from the start to finish, which facilitated data collection while simultaneously building capacity in applying the concept of ecosystem services among the target audience.

In total, more than 10 different ecosystem services have been valued in monetary terms. The totaleconomic value (TEV) of the ecosystem services provided by the marine and terrestrial ecosystems of Bonaire is $105 million per year. This TEV and its underlying components can be used to build a strategy for effective conservation measures on Bonaire. After extensively analyzing different scenarios for future ecosystem services values one result becomes very clear: an ounce of prevention is worth a pound of cure. In other words, it is more efficient to prevent extensive environmental damage than trying to revitalize the environment while there are still threats at hand. With the current threats unmanaged, the TEV of Bonairean nature will decrease from $105 million today to around $60 million in ten years time and to less than $40 million in 30 years. The project is well documented and provides several extensive online reports, five easily accessible policy briefs and a beautiful film documentary that translates the scientific results into real life situations on Bonaire.
