The Reef Is in Serious Decline
Severe degradation is already visible at a number of locations and is compounded by disease, thermal stress, wastewater and other local pressures.
Curaçao, when a Diving Industry Outgrows the Reef That Sustains It
Operation Caribe · Curaçao Field Review
A mature recreational diving destination under growing environmental, economic and management pressure
IADP’s two-month field review found a widening disconnect between reef condition, the structure of the recreational diving market, Curaçao’s economic dependence on its marine environment and the systems responsible for protecting that resource. The problem is no longer simply identifying what is going wrong. Curaçao now needs a practical structure capable of turning decades of knowledge into coordinated action.
As part of Operation Caribe, the International Association of Diving Professionals conducted an extended field review of Curaçao’s recreational diving sector and marine environment during two months of direct professional involvement on the island. The objective was to assess reef condition, examine the structure of the recreational diving training and exploration sector, and understand how business activity, regulation, economic dependence and environmental responsibility interact within one of the Caribbean’s best-known diving destinations.
Curaçao in Numbers
Before looking at the individual findings, the scale of the relationship between Curaçao, its reefs and its tourism economy is worth establishing. Curaçao covers approximately 444 square kilometres, yet supports a remarkably dense recreational diving market around a comparatively limited reef resource.

About the provider estimate: Curaçao does not currently provide an easily accessible consolidated public register covering every recreational diving centre, school, independent provider, micro-operation and other commercial entity offering diving services. The 150–200 figure is therefore an IADP field estimate based on identifiable businesses, agency directories, websites, social media, local market review and direct observation. It should not be interpreted as an official registry count.
The scale of the contradiction is immediately visible: a small island, a finite reef resource, a highly fragmented recreational diving market and an economy deriving substantial value from tourism linked directly and indirectly to the marine environment.
What We Found Underwater
The most serious finding concerned the condition of the reefs. Across repeated dives, IADP observed widespread deterioration of coral structure, extensive areas of dead or degraded substrate, significant algal presence, disease and recent coral mortality.
At several locations the level of visible degradation was extreme, with the most severely affected sites appearing to show approximately 80–90 percent loss of healthy coral structure relative to what would normally be expected from a healthy Caribbean reef.
Field assessment: the 80–90 percent figure relates to specific sites observed during the review. It is not presented as an island-wide scientific coral-cover measurement.
The broader scientific record nevertheless confirms serious decline. CARMABI identifies pollution, coastal development, overfishing, climate change, tourism pressure and coral disease among the pressures affecting Curaçao’s reefs. The institution has also reported that approximately 28 percent of Curaçao’s coral reefs died within a single year during the recent combination of severe thermal stress and coral disease, including Stony Coral Tissue Loss Disease.
The important distinction is that the field observations in this review and the scientific measurements are not the same thing. IADP is reporting what was repeatedly observed during professional diving activity. Scientific organisations such as CARMABI provide the long-term monitoring and quantitative research required to place those observations in a broader ecological context.
The Pressure Starts on Land
Recreational diving is not the sole or necessarily the principal cause of Curaçao’s reef decline. Climate stress, disease, coastal development, fishing pressure and land-based pollution all interact with what happens underwater. Wastewater management is one of the clearest examples.
CARMABI has reported that Curaçao’s existing wastewater-treatment capacity is insufficient and that many homes and businesses remain dependent on septic systems. Wastewater and nutrients can reach coastal waters through groundwater transport, leakage, overflow and direct discharge.
In 2025, CARMABI reported that approximately 300,000 litres of untreated sewage and other waste per day were being discharged at Shut, in addition to other documented coastal discharge points. Excessive nutrient input encourages algal growth, reduces water quality and places additional pressure on corals already affected by elevated temperatures, disease and other stresses.
Curaçao internationally markets its marine environment as a tourism asset. Protecting that asset therefore requires more than coral restoration alone. Reef management, wastewater infrastructure, coastal development, fisheries, tourism and commercial marine activity ultimately have to be treated as parts of the same environmental system.
From Active Stewardship to Declining Infrastructure
Curaçao’s present condition is particularly striking because the island once maintained a much more visible system of practical reef stewardship. During the mid-1980s, mooring systems were installed at a number of dive sites to reduce anchor damage and provide controlled access to the reef, with the Curaçao Sea Aquarium playing an important role in supervising and maintaining elements of that system.
The historical comparison is especially relevant because the IADP reviewer began his professional diving career in Curaçao during that period and was directly involved in installing and working on several of those original mooring systems. Some of the original blocks still visible on the seabed today were installed during work in which the reviewer personally participated.
During the 2026 review, the original mooring blocks themselves remained in place. What had largely disappeared were the anchor chains, operational moorings and the continuous maintenance system required to keep them functioning.
Curaçao did develop practical reef-management infrastructure. The concern is not that the island never possessed such systems, but that infrastructure already installed decades ago was no longer supported by an equivalent permanent island-wide maintenance structure.
The same pattern can be seen in environmental interpretation. In the 1980s, parts of the island included educational snorkelling routes with underwater markers identifying coral species and explaining the reef environment.
Elements of that infrastructure are still present. Some markers and installations have become overgrown, degraded or are no longer actively maintained. The issue is therefore not simply that the infrastructure disappeared; it is that systems which once demonstrated organised, practical stewardship have in many places ceased to function as maintained programmes.
This reflects a broader shift from practical, visible reef stewardship toward a more fragmented model in which scientists, conservation organisations, individual operators, volunteers and government bodies each contribute elements of the solution without one permanent operational system responsible for marine infrastructure as a whole.
↑ Back to report navigationA Diving Industry That Has Outgrown Its Management Structure
The environmental problem exists alongside a second structural issue: the increasing fragmentation of Curaçao’s recreational diving market. The island supports established dive centres, small schools, boutique operators, one-person businesses, micro-operators and other entities competing within a finite visitor market.
Digital marketing and direct online communication have reduced the barriers to entering that market. A small provider can now promote courses, guided dives and other services directly to visitors without the infrastructure traditionally associated with a larger dive centre.
Small providers are not inherently a problem. Many offer excellent, highly personalised services and represent legitimate entrepreneurship. The structural problem begins when the total supply of commercial services expands faster than the customer base capable of supporting them.
A Fragmented Provider Base
The wider market extends well beyond the formally Quality Assured dive schools and includes one-person businesses, micro-operators, small schools, established centres and other providers operating across the island.
Finite Demand
Visitor demand does not automatically increase because additional businesses begin offering diving services. Increasing supply can therefore divide the available market among a growing number of providers.
The Market Appears Oversaturated
IADP has not conducted a formal econometric study determining the optimum number of recreational diving businesses Curaçao should support. It would therefore be inappropriate to present a precise market-capacity limit.
The field review did, however, identify indicators consistent with significant market saturation: a very large provider base relative to the formally visible sector, persistent price competition, pressure on margins and repeated concerns about the long-term viability of established operations.
The problem is not simply that Curaçao has many diving businesses. The question is whether the economic structure allows compliant operators to remain viable while maintaining appropriate professional, safety, employment, insurance and environmental standards.
Certification Is Not Regulation
Training organisations such as PADI, SSI, NAUI, CMAS, NOB and others establish educational standards and certification systems within recreational diving. Their role is fundamental, but certification is not destination or market regulation.
A training organisation may certify an instructor. It does not determine whether a commercial business is properly registered in Curaçao, whether appropriate insurance is maintained, whether local operating requirements are met or what environmental obligations apply to commercial access to a finite marine resource.
The distinction is simple: certification establishes competence within a training system. Regulation establishes the legal and operational framework within which commercial recreational diving businesses operate.
A Gap Between the Formal Sector and the Actual Market
The Curaçao Tourist Board’s Quality Assurance programme provides an important formal structure. In March 2026, 22 dive schools completed the Quality Assurance certification process following audits addressing quality, safety and operational consistency. CTB also identifies environmental responsibility as part of the programme’s objectives.
The wider commercial market is considerably more difficult to quantify. There is no easily accessible consolidated public register showing every recreational diving provider, one-person business, micro-operation and other entity actively offering diving services across the island.
Curaçao’s wider recreational diving market can often be identified more easily through agency directories, websites, social media and local knowledge than through one transparent destination-level commercial framework.
An Industry Losing Its Stewards
During the field review, IADP encountered a recurring pattern among long-established owners and operators. Many are approaching retirement, reducing their involvement or considering how their businesses can continue after they leave. Some have successors. Others do not.
These operators have witnessed the full cycle of Curaçao’s modern recreational diving industry: expansion, the development of mooring systems and educational initiatives, increasing competition, changing margins and deterioration of the reefs themselves.
The recurring impression was not simply indifference. It was fatigue.
For decades, parts of Curaçao’s reef stewardship depended on individual operators contributing time, boats, fuel, equipment, labour and expertise beyond what their commercial businesses formally required. As the market expanded, those responsibilities did not always expand into an equivalent island-wide management structure.
A strategically important environmental asset should not depend on whether individual commercial operators happen to have enough spare time, money and goodwill to maintain it.
The Reef Is Also an Economic Asset
Curaçao’s reefs are not simply environmental assets. They form part of the island’s productive tourism infrastructure.
A Curaçao diving-industry assessment reported in 2017 that dive visitors generated expenditure through diving, accommodation, food and beverage, car rental, equipment and other related spending. The study estimated approximately US$41.3 million in annual contribution to the local economy.
That assessment predates COVID-19 and should not be presented as a current valuation of Curaçao’s diving sector. Its importance is historical: recreational diving was already generating economic activity measured in tens of millions of dollars almost a decade ago.
The broader tourism economy has since grown dramatically. Curaçao’s official 2024 tourism report calculated approximately US$2.7 billion in total direct and indirect economic impact, including cruise tourism. That figure cannot be attributed to diving, but it demonstrates the scale of the island’s dependence on a tourism product in which beaches, coastal waters and the marine environment remain central assets.
Publicly available information does not provide an equivalent simple figure showing how much of the economic value generated through reef-based tourism is systematically reinvested in reef infrastructure, moorings, rehabilitation, monitoring, wastewater improvements and permanent marine operational capacity.
A reef supporting substantial economic activity should not be treated as an asset capable of maintaining itself.
The Economic and Environmental Problems Are Connected
Market pressure, reef decline and economic dependence on reef-based tourism should not be treated as unrelated issues.
A saturated market can place pressure on pricing and profitability. Lower margins can make voluntary investment in moorings, conservation, environmental education, monitoring and maintenance more difficult. At the same time, declining reef quality progressively weakens the tourism product on which those same businesses depend.
This does not establish that market saturation caused Curaçao’s reef decline. It demonstrates something different: a conservation model dependent heavily on voluntary commercial stewardship becomes increasingly fragile when the businesses expected to provide that stewardship are themselves under pressure.
1. Fragmentation
An increasingly diverse provider base operates within the same finite destination and marine resource.
2. Economic Pressure
Price competition and weaker margins can reduce the capacity for voluntary long-term investment outside direct revenue-producing activity.
3. Reef Decline
Environmental deterioration progressively weakens the natural product on which recreational diving and a wider part of the tourism economy depend.
Five Key Findings
02
The Market Appears Oversaturated
A large and fragmented recreational diving provider base competes within a finite tourism market, with indicators of sustained economic pressure.
03
The Reef Is Economic Infrastructure
Dive tourism has historically generated tens of millions of dollars in annual local economic activity while the wider tourism economy now operates on a multi-billion-dollar scale.
04
Voluntary Stewardship Is Not Enough
Moorings, monitoring, conservation and environmental maintenance cannot depend indefinitely on the spare resources of individual businesses, volunteers and conservation organisations.
05
Curaçao Is Losing Institutional Memory
Experienced operators are ageing, retiring or disengaging, taking decades of practical knowledge and voluntary stewardship experience with them.
The central finding: Curaçao’s reef decline, fragmented diving economy and dependence on marine-based tourism intersect within a management structure that has not evolved sufficiently with the scale of the modern industry.
Curaçao Still Has Something Worth Saving
The findings of this review should not be interpreted as declaring Curaçao a lost diving destination. It is not.
The island still possesses exceptional shore-diving access, experienced operators, substantial accumulated industry knowledge, surviving high-quality reef areas and internationally respected marine research capacity.
Organisations such as CARMABI provide scientific expertise that many destinations do not possess. CTB already operates a Quality Assurance framework for dive centres. Conservation organisations, individual businesses and volunteers continue working on marine protection and restoration.
Curaçao is not starting from zero. The island already possesses scientific knowledge, professional experience, tourism institutions, conservation capacity and substantial accumulated knowledge of its marine environment. The opportunity is to organise those strengths around a permanent implementation structure.
What is missing is not another warning that the reef is declining. What is missing is an implementation architecture capable of coordinating, financing and sustaining the response.
From Diagnosis to Action
Curaçao does not lack scientific knowledge about the pressures affecting its marine environment. Nor does it lack professional expertise, conservation organisations, tourism institutions or businesses with an interest in protecting the reef.
The harder challenge is converting that knowledge and goodwill into coordinated, permanent execution.
IADP therefore proposes that the first step should be the creation of a Curaçao Marine Resource Task Force or equivalent working group with a defined mandate and a defined timetable.
1. Establish a Curaçao Marine Resource Task Force
The task force should bring together the institutions and professional groups already involved with Curaçao’s marine environment rather than attempt to replace them.
Participants should include relevant government authorities, marine scientists, the Curaçao Tourist Board, tourism-industry representation, established conservation organisations, representatives of the recreational diving industry and other relevant marine stakeholders.
IADP, including its Go Blue environmental programme, is prepared to participate in such a process and contribute professional diving, industry-development and operational expertise.
The task force should not become another permanent discussion body. Its primary purpose should be to produce an agreed, costed and measurable short-, medium- and long-term marine-resource management plan and establish responsibility for implementing it.
2. Develop One Marine Resource Management Plan
The management plan should connect reef protection with the economic activities and land-based pressures affecting the same resource.
Short Term · 0–24 Months
Inventory reef and dive-site infrastructure; inspect existing moorings; identify priority damaged sites; establish baseline monitoring; map the commercial recreational diving sector; identify immediate wastewater and coastal threats; define responsibilities and establish an implementation budget.
Medium Term · 2–5 Years
Establish permanent marine operational capacity; rebuild and maintain mooring infrastructure; implement priority restoration programmes; formalise transparent commercial oversight; create structural financing; and publish measurable environmental and operational results.
Long Term · 5–15 Years
Integrate reef management with wastewater, fisheries, coastal development and tourism planning; maintain continuous scientific monitoring; establish resilience and recovery targets; and secure permanent financing for marine-resource management.
3. Know Who Is Operating
An effective destination-level management system also requires a clearer picture of who commercially provides recreational diving services.
Curaçao should examine the creation of a transparent commercial diving register or equivalent mechanism identifying operating entities and the applicable registration, insurance, permitting and professional requirements.
This does not mean eliminating legitimate small providers. It means ensuring that businesses competing within the same commercial market operate within a transparent and consistently applied framework.
Existing structures provide a starting point. The CTB Quality Assurance programme already demonstrates that destination-level quality, safety and environmental criteria can be organised around a common framework. A wider commercial-management system could build on existing competence rather than duplicate it.
4. Make Environmental Responsibility Structural
Reef stewardship should no longer depend primarily on voluntary participation. Commercial operators, tourism beneficiaries, public authorities and visitors all benefit from a functioning marine environment.
Those who derive economic value from access to Curaçao’s marine environment should participate in protecting the natural asset that generates that value.
Making It Work: A Permanent Marine Operations Capacity
Planning without operational capacity will not be enough. Curaçao should examine the establishment of a permanent professional marine field unit whose daily responsibility is practical reef and marine infrastructure management.
Such a unit could combine marine biology, professional diving, vessel operations, mooring installation, underwater technical work, monitoring and restoration support. A team of approximately seven to eight professionals could include an operations manager, marine biologist or restoration lead, vessel captain or senior marine technician, professional diver-technicians and logistical support.
The unit would require a properly equipped work vessel, diving and compressor capability, mooring hardware, workshop and maintenance capacity, monitoring equipment and access to the materials required for reef-rehabilitation projects.
Inspect & Monitor
Systematically inspect moorings, priority dive sites, damaged areas and marine infrastructure rather than relying on occasional reports.
Repair & Install
Maintain moorings, replace failed infrastructure and provide practical underwater response capacity around the island.
Restore & Revisit
Support scientifically directed reef rehabilitation and return repeatedly to priority sites to measure progress over years rather than weeks.
A reef-dependent tourism economy should not depend primarily on volunteers to maintain the infrastructure protecting the resource on which that economy depends.
What Would This Cost?
IADP has not prepared a formal Curaçao government budget for such a programme, and the final cost would depend on salaries, vessel specification, procurement, restoration scope, insurance and administrative structure.
An indicative planning scenario nevertheless shows that the scale is manageable. A professional seven- to eight-person operation with vessel costs, fuel, maintenance, equipment, mooring materials, restoration work and monitoring could plausibly require approximately US$700,000–1.1 million per year in recurring operating expenditure.
Initial capital investment for a suitable work vessel, compressor systems, workshop equipment, transport, diving equipment and initial infrastructure inventory could add approximately US$500,000–750,000, depending on specification.
These figures are an indicative IADP planning scenario, not a tender, quotation or government budget. Their purpose is to establish order of magnitude and enable comparison with the documented economic value of the resource being protected.
Even a recurring programme costing approximately US$1 million annually would equal only about 2.4 percent of the diving industry’s historical US$41.3 million annual economic contribution estimated in 2017.
The comparison is not intended to suggest that 2.4 percent is the correct levy or funding level. It illustrates that a permanent professional management system need not be economically disproportionate to the value historically generated by the sector itself.
A Dedicated Marine Contribution
The programme also does not necessarily have to depend entirely on Curaçao’s general government budget.
Bonaire provides a long-established regional example of visitors contributing directly to the management of a marine resource. Its system historically used annual nature tags familiar to generations of visiting divers and has since evolved into a unified Nature Fee. STINAPA currently requires most visitors using the Bonaire National Marine Park to pay an annual US$40 Nature Fee.
Curaçao could examine whether an equivalent marine-user contribution, nature fee or other dedicated mechanism could finance part or all of its permanent marine-management programme.
The precise mechanism would need to be determined locally. What matters is that revenue raised for the marine environment should be visibly connected to marine outcomes.
Ring-Fence the Money
A new fee would be more transparent if visitors, businesses and the public can see where the money goes.
An IADP financing model would therefore pair any dedicated marine contribution with clear financial safeguards.
Dedicated Fund
Marine-user revenue could be ring-fenced for defined marine-resource management purposes rather than entering unrestricted general revenue.
Transparent Accounts
Annual income, expenditure and major procurement could be published in a format that businesses, residents and visitors can understand.
Measured Results
Reporting could show what the programme actually delivered: moorings installed or repaired, sites monitored, restoration undertaken, water-quality indicators and other agreed outputs.
An oversight model could include representatives from government, marine science, tourism, conservation and the professional diving sector, supported by appropriate independent financial controls.
The objective would not simply be to create another environmental fee. It would be to create a permanent financing mechanism tied directly to visible, measurable marine-management outcomes.
What Should Happen First?
The scale of Curaçao’s environmental problems means that no single task force, boat or restoration project will repair the reef system by itself. The purpose of the proposed model is to create continuity.
First 12 Months
Establish the task force; agree its mandate; map stakeholders and operating responsibilities; inventory existing moorings and priority dive sites; establish the commercial-provider baseline; identify immediate intervention areas; review available scientific monitoring; define funding options; and produce the first integrated management plan.
Years 1–3
Establish permanent operational capacity; procure or assign a work vessel; implement a systematic mooring programme; begin priority restoration and monitoring; introduce the financing mechanism; strengthen commercial transparency; and publish annual operational and environmental results.
Longer-term management should then integrate reef protection with wastewater, coastal development, fisheries, tourism growth and other pressures affecting the same marine system.
↑ Back to report navigationOperation Caribe: The Wider Caribbean Lesson
Curaçao is not an isolated case. Across the Caribbean, reef systems face increasing environmental pressure while tourism, coastal development and recreational diving activity continue to evolve.
Training organisations continue creating new generations of qualified divers and professionals, while many destinations possess limited mechanisms for understanding the real size and structure of their commercial provider markets. Environmental stewardship frequently remains divided between scientific institutions, conservation organisations, volunteers, public authorities and a relatively small number of committed operators.
Curaçao makes these contradictions particularly visible because the island combines a mature recreational diving industry, exceptionally easy reef access, a fragmented provider market, substantial tourism value and serious environmental pressure within a limited geographical area.
The future of Caribbean diving therefore cannot be measured solely by certification numbers, tourism arrivals or dives sold.
It must also be measured by whether businesses remain viable, operating standards are coherent, marine infrastructure is maintained, environmental responsibility is shared fairly, economic value is translated into protection of the underlying resource and healthy reefs remain for future generations.
Curaçao does not need another warning that reefs are under pressure. It needs a path from knowledge to implementation. The institutions, expertise and economic justification already exist. The next step is to organise them around a common plan and provide the permanent operational capacity to carry that plan out.
