12、3 THE OCEAN ECONOMY TO 2050 OECD 2025 Foreword The ocean economy is a vital component of our global economy and policymakers require data-driven and evidence-based insights to guide their decision-making.The Ocean Economy to 2050 builds on a new quantitative and foresight analysis of potential pathw
13、ays for the ocean economys development,highlighting that a healthy ocean is crucial for climate and biodiversity processes,as well as for the economy.If the ocean economy were a country,it would be the fifth largest economy in the world.But the sustained growth and resilience of the ocean economy of
14、 the past 25 years is not set to continue.Growing pressures need to be tackled to keep the ocean economy on a path that contributes to sustainable economic development with employment that millions rely on.To move forward,science-based decisions and improved ocean management are neededonly a quarter
15、 of the ocean floor is mapped,very few countries have developed full scale marine spatial planning,and much remains to be discovered and protected in the deep sea.Harmful subsidies must end,in fishing for instance.Transitions to cleaner energy and greater use of digital technologies should be encour
16、aged,both are critical to mitigating climate change and boosting the productivity of ocean industries.Developing unbiased evidence to guide decisions on ocean management and governance will be key.This report builds on more than a decade of OECD ocean economy work,with statistical measurement and oc
17、ean science and innovation at its core,supported steadily by several countries.The OECD Ocean Economy Monitor programme supports informed decision-making on a global scale.It provides insights into the economy-,science-and innovation-related aspects of the ocean economy as well as its policy environ
18、ment.Leveraging harmonised country-level statistics from OECDs unique Inter-Country Input-Output(ICIO)tables and other quantitative and qualitative data sources,the Monitor currently tracks 33 ocean economic activities across 142 coastal countries,spanning more than 25 years.It forms an unprecedente
19、d source of new analysis to support evidence-based policies.The consistent measurement methods applied across countries are unlocking unparalleled opportunities to empower OECD member countries and partner economies with new evidence to support their strategic objectives and involvement in different
20、 multilateral processes.Through collaboration with OECD member countries and partner economies,the benefits of this work should be widely shared,enabling more countries to harness the potential of the ocean economy while safeguarding its long-term sustainability.4 THE OCEAN ECONOMY TO 2050 OECD 2025

67、 and who is it for?The Ocean Economy to 2050 report is a new OECD resource to enhance understanding of the evolving ocean economy landscape.It presents unprecedented data on the ocean economy covering almost three decades(1995-2020)for more than a hundred countries and thirty-three ocean economic ac
68、tivities.In addition,it provides a comprehensive analysis of possible projected growth trajectories,challenges,and opportunities within the global ocean economy over the next 25 years.Building on ten years of dedicated OECD ocean economy work(with the landmark 2016 report on The Ocean Economy in 203
69、0),and highlighting important OECD wide ocean work,this report aims to offer insights into how ocean economic activities can contribute to prosperity,employment,and innovation,while ensuring the conservation,restoration and sustainable use of marine ecosystems.By examining emerging trends,technologi
70、cal advances,and policy developments,the report seeks to inform stakeholders about possible future paths of the ocean economy All at a time when ocean health deterioration,climate change acceleration and biodiversity loss are increasingly affecting countries around the world.This report is intended
71、for a diverse audience including policymakers,industry leaders,researchers,and civil society organisations engaged in ocean-related activities.The report is structured in six chapters:Chapter 1 provides an overview of the main findings from the publication and key recommendations for policymakers.Ch
72、apter 2 provides the general context-setting for the rest of the publication,with a brief review of major evolving ocean policy landscape and governance issues that are impacting the ocean economy.Chapter 3 delivers new OECD statistics and analysis on ocean economic activities and their evolution ov
73、er recent decades.Chapter 4 identifies key factors of performance for the ocean economy.Based on these,it projects potential ocean economy growth to 2050 under the assumption that historical trends persist and establishes a theoretical baseline scenario used in the next chapters.Chapter 5 analyses h
74、ow major shaping forces could affect potential ocean economy trajectories o as describes how the historical record is not necessarily a good indicator of future ocean economic growth.11 THE OCEAN ECONOMY TO 2050 OECD 2025 Chapter 6 explores further how combinations of several of these global shaping
75、 forces may affect specific areas of the ocean economy in the decades to come.It then outlines two future scenarios for the ocean economy differentiated by alternative approaches to the global energy transition.Basic concepts used in measurements of the international ocean economy in the OECD Ocean
76、Economy Monitor and featured in this report Ever since the 2016 release of The Ocean Economy in 2030(OECD,20162),the OECD has described the ocean economy as an interrelated system of two pillars:economic activity and the marine ecosystem assets and services that they rely on.Interlinkages between oc
77、ean economic activity and the marine environment are therefore a founding concept in analysis of the ocean economy:discussion of one pillar is incomplete without considering the effects that changes in it may have on the other.Although work is ongoing in various international fora to develop the sta
78、ndards and guidelines required to account for the marine environment,coherent cross-country statistics are not yet available.The quantitative elements of this report are therefore focused on statistics on ocean economic activities.The marine economic-environmental linkages described in this report u
79、se either ad-hoc data from external sources or are dealt with qualitatively.As and when internationally comparable statistics on marine environmental-economic linkages become available,the OECD Ocean Economy Monitor will expand to include them.This novel OECD programme provides a unique platform for
80、 measuring the global ocean economy over time using harmonised country-level statistics and other data sources.The OECD Blueprint for Improved Measurement of the International Ocean Economy(Jolliffe,Jolly and Stevens,20216)provides a definition of ocean economic activities for the purposes of scopin
81、g statistical measurement.The OECD Eight Lessons Learned from Comparing Ocean Economy Measurement Strategies Across Countries(Jolliffe and Jolly,20247)working paper uses principles from the system of national accounts to highlight commonalities and differences in approaches and provides recommendati
82、ons for integrating ocean economy measurements with national statistics.The OECD Ocean Economy Monitor applies definitions from the OECD Blueprint and many of the principles of national accounting from the OECD comparison of national approaches to the measurement of international statistics on ocean
83、 economic activities.Current scope and coverage of measurements of the international ocean economy in the OECD Ocean Economy Monitory and featured in this report Ocean economic activities are defined in the OECD Ocean Economy Monitor and this report according to the OECD Blueprint(Jolliffe,Jolly and
84、 Stevens,20216)as groups of establishments from any institutional sector engaging in the same or similar kinds of economic activity that:take place on or in the ocean produce goods and services primarily for use on or in the ocean extract non-living resources from the marine environment harvest livi
85、ng resources from the marine environment use living resources harvested from the marine environment as intermediate inputs would likely not take place were they not located in proximity to the ocean,or,gain a particular advantage by being located in proximity to the ocean The economic statistics pro
86、duced for the OECD Ocean Economy Monitor and presented in this report are currently harmonised across 33 individual ocean economic activities for 142 coastal countries between 1995 and 2020.Each ocean economic activity is measured as distinct from all others so that ocean 12 THE OCEAN ECONOMY TO 205
87、0 OECD 2025 economic activities can be aggregated into wider groupings called ocean economic activity groups.There are seven ocean economic activity groups and the economic statistics in this report are generally focussed on this level of aggregation.Estimates of the total ocean economy refer to the
88、 aggregation of all 33 currently measured ocean economic activities within a country.The links between the three levels of the hierarchy in the OECD Ocean Economy Monitor are presented in Table 1.Estimates of the global ocean economy in this report refer to the aggregation of all 33 currently measur

126、my in 2019.From 1995 to 2020,it contributed 3%to 4%of global gross value added(GVA)and employed up to 133 million full-time equivalents(FTEs).The global ocean economy doubled in real terms in 25 years from USD 1.3 trillion of GVA in 1995 to USD 2.6 trillion in 2020,growing at an annual average rate
127、of 2.8%.Employment levels remained relatively constant,reaching a peak of 151 million Full Time Equivalents(FTEs)in 2006,falling to 101 million in 2020 due to COVID-19,with recovery since then.Over 75%of global ocean economic growth between 1995 and 2020 originated in countries in Asia and the Pacif
128、ic.Eastern Asia alone accounted for 56%of global ocean economy expansion,while Europe and North America experienced slower growth.The Peoples Republic of China,the United States,Japan,Norway,and the United Kingdom had the largest ocean economies in absolute terms on average over the period.However,c
129、ountries like Norway had the highest ocean-to-overall economy share,demonstrating regional disparities in reliance on the ocean economy.Tourism and offshore oil and gas extraction generated about two-thirds of total gross value added.However,workforce distribution varied widely.Marine and coastal to
130、urism was the largest employer,while offshore oil and gas extraction created high economic output but relatively low employment.Output from shipbuilding and offshore wind energy also expanded rapidly albeit from a smaller base.Major disruptions will reshape the ocean economy in the coming decades If
131、 historical trends were to continue,the global ocean economy could be nearly four times larger by 2050 than in 1995.However,various forces could slow or even reverse growth by 2050 if no policy actions are taken.Global shaping forces will impact ocean health and the ocean economy.Factors such as pop
132、ulation growth,climate change and other environmental pressures,trade and globalisation,the energy transition,technological advances,and geopolitical dynamics along with their interactions will shape ocean health and the future growth trajectory of the ocean economy.Qualitative and quantitative proj
133、ections highlight climate change,energy transitions,and advances in science,technology,and innovation as key drivers.Faltering productivity trends and digitalisation gaps will also shape the ocean economys future potential.While some ocean economic activities outpaced average industry growth between
134、 1995 and 2020,multifactor productivity declined in more than half the ocean economic activity groups analysed.The contribution of capital services to ocean economic growth was heavily tilted towards non-information and 17 THE OCEAN ECONOMY TO 2050 OECD 2025 communication technology assets providing
135、 some evidence that ocean economic activities are not making the most of powerful drivers of productivity to prepare for an increasingly automated future.Different pathways for a global energy transition will affect ocean economic growth in different ways.In an accelerated transition to low-carbon e
136、nergy,the ocean economy would continue to grow through 2050 to around 2.5 times the size it was in 1995.The composition of the ocean economy would change,with marine and coastal tourism remaining dominant and offshore oil and gas declining as a proportion of total ocean economy GVA.A stalled transit
137、ion scenario could lead to a decline in overall ocean economic activity from the level reached in 2020,mainly due to a combination of a lack of investment in productivity and increasing negative effects of climate change on many parts of the ocean economy.Four strategic priorities can help achieve a

225、istorical record would lead to overly optimistic growth trajectories.Pressures on the ocean economy will likely grow in the coming decades Most ocean economic activities should continue benefitting from underlying economic and social trends in the next two decades.However,even with innovations on th
226、e horizon to face some of these challenges,pressures are mounting on many fronts for the ocean and several ocean economic activities.In all scenarios,ocean economy growth will be affected and may eventually decline if no actions on improving ocean governance are taken.The policy frameworks and gover
227、nance mechanisms for the ocean and the ocean economy have been strengthening over the past decade at both national and international levels.However,as strategic and economic interests in the ocean continue to expand,so do the challenges of co-operation and effective management of this global commons
228、(Chapter 2).The increasing territorial claims over ocean watersnow encompassing approximately 39%of the global ocean under some national sovereign rightsalong with the expansion of illicit activities at sea,are transforming the ocean into an increasingly competitive environment.A range of critical i
229、ssuesfrom safeguarding freedom of navigation,regulating greenhouse gas emissions from ships,and combating illicit activities such as illegal,unreported,and unregulated(IUU)fishing,drug trafficking,and industrial pollution from both land and maritime sourceswould require increased attention from poli
230、cymakers at different levels and in coordination.Without actions,these challenges could become ever more complex and intertwined,threatening not only further ocean health but also economic activities.The rapid expansion and concentration of ocean industries,coupled with overfishing,expanded biologic

233、tourism(Chapter 2).Growing climate change effects(sea level rise,acidification,changing fish stocks patterns)will affect not only ocean health and its biodiversity,but also industries faced with growing risks of extreme weather and sea level rise impacts(growing threats to infrastructure at sea:oil
234、and gas rigs,offshore wind,aquaculture and ports,as well as capture fisheries)(OECD,20221;OECD,20162).Increased terrestrial pollution(plastics,chemicals,waste management)will be impacting several ocean-based industries,particularly those relying on living resources(capture fisheries)and pristine env
235、ironment(coastal and marine tourism).The amount of plastic entering the environment annually by 2040 is for instance expected to nearly double compared to 2022 if there are no policy reorientations(OECD,20243).Furthermore,the ocean economy risks missing out on potential productivity gains from major
236、 economic transformations expected in the decades to come.Investment in the ocean economy has been tilted away from information and communication technologies(ICTs)and towards capital 29 THE OCEAN ECONOMY TO 2050 OECD 2025 such as machinery and equipment.But ICTs can drive efficiency gains and the f
237、ailure to integrate advances in the underlying technologies may over time lead to serious loss of competitiveness.Recent scientific and economic literature have been used to recognise differences in the magnitude of the potential effects of various shaping forces on the future global ocean economy.F
238、igure 1.9 displays the results of this modelling work.Each shaping force is considered in isolation,all else remaining equal,and compared to the baseline projection which assumes that historical trends persist.The shaping force with the largest upside potential on the global ocean economy is an incr

247、l ocean economic activity would decline to end the period around 20%lower than it was in 2020.The alternative scenarios also drive important differences in the composition of the ocean economy.In the accelerated transition scenario,a pronounced shift away from offshore oil and gas extraction reduces
248、 the activitys share of total global ocean economy GVA from a third in 2020 to one-fifth in 2050.In a stalled transition,the effect goes in the other direction and offshore oil and gas extraction increases its share of the total ocean economy to become the dominant activity around 2030.In the accele
249、rated transition scenario,marine and coastal tourism remains the dominant ocean economy activity group through to 2050.But a stalled transition would reduce its share substantially as offshore oil and gas extraction expands.Offshore wind and marine renewables expand at a much faster rate in the acce

256、of biodiversity including marine ecosystems,alongside support for the energy transition,are policy priorities that extend well beyond the ocean economy itself(OECD,20244).However,as seen in the different scenarios,climate change and energy transition pathways could impact deeply the growth of the oc
257、ean economy under different assumptions,as compared to historical trends with even the possibility of an eventual decline in global ocean economic activity.Successfully developing a resilient and more productive ocean economy will depend largely on the worlds ability to control climate change and mi
258、tigate its worst effects,by enhancing biodiversity conservation,sustainable use and restoration as well,and harnessing the expected transformation of the global energy system.The ocean plays a crucial role in climate regulation,absorbing approximately 25%of global carbon emissions,with stored carbon
259、 locked away in seafloor deposits for potentially hundreds of years(IPCC,20215).This process is supported by a diverse range of marine species,from plankton to mesopelagic fish,which help sustain carbon sequestration(IPBES,20196).However,while this absorption is part of the climates natural cycle,th
260、e current levels of emissions are increasingly disrupting the ecological functions of marine organisms,threatening biodiversity and the ecosystem services it provides,but also different ocean processes including ocean circulation(Mercator,20257).Continued commitment to curb overall carbon emissions
261、will be necessary,as the impacts of climate change increasingly compromise ocean health and the ocean economic activities that depend on it,as shown in this report.Eutrophication and acidification are placing increasing pressure on marine ecosystems;while rising temperatures,sea levels and extreme w
262、eather patterns further exacerbate these challenges,posing various degrees of risk to key activities such as shipping,fisheries,coastal tourism,and port infrastructure.Every incremental increase in temperature compounds these risks,underscoring the need for decisive action.The consequences will be p
263、articularly severe for coastal communities and low-income countries in particular lacking finance for adaptation.Preventing the rapid loss of biodiversity,including species and marine ecosystems such as mangroves,salt marshes,coral reefs,and seagrassdriven by human activities particularly in populat
264、ed coastal areas will be vital.Accelerated loss threatens not only critical roles of these ecosystems in regulating water quality,acting as carbon sinks,and providing coastal defences but also disrupts key ocean-based economic activities,including fishing and coastal tourism that provide food securi
265、ty and livelihoods.Widespread pollution,from plastics but not only,also contributes to these losses(OECD,20258).Deep sea ecosystems and their role in supporting marine food webs and climate processes are also only starting to be understood,thanks to improved ocean and seabed exploration and mapping(
266、Levin,20219).Conservation,sustainable use as well as restoration policies with enforcement mechanisms,are needed to support these valuable ecosystems.Steering the global energy and transportation system on a path to transition to low-carbon emissions would improve ocean health,despite a reliance on
267、fossil fuels for the foreseeable future(IEA,202410).An acceleration would mitigate long-term climate change impacts,while adaptation strategies could be implemented in parallel to prepare for accelerated changes in ocean conditions.Science and technology,and particularly digitalisation have a role t
268、o play in this transition,enabling more efficient and sustainable ocean management.Addressing these challenges requires sustained and targeted public and private investments,which not only support economic resilience but also generate long-term benefits for societies and businesses alike 32 THE OCEA
269、N ECONOMY TO 2050 OECD 2025 (OECD,202111;OECD,202512).Overall,encouraging the use of advanced technologies to reduce emissions and enhance energy efficiency would strengthen the long-term performance of ocean economic activities,while meeting wider climate and biodiversity goals.What actions can pol
270、icymakers take to set the ocean economy on a more sustainable pathway?The report highlights both strengths and vulnerabilities of the ocean economy.While ocean economic activities have outpaced overall economic growth for the past two decades,several structural weaknesses remain and will only grow i
271、n view of mounting pressures.Productivity growth has been sluggish in many ocean economic activities,and serious challenges lie ahead in terms of ocean health,governance,and digitalisation.A combination of stronger governance mechanisms,responsible business practices,and scientific innovation can co
272、ntribute to have economic activities coexist better with the oceans health,ensuring that the ocean remains a global common for future generations while supporting sustainable economic growth.Four main strategic orientations for targeted policy interventions are needed:1.Strengthening governance fram
273、eworks and collaboration 2.Promoting technological innovation and digital transformation 3.Enhancing sustained ocean observations and scientific research to develop knowledge on ocean processes and improve management 4.And expanding the integration of developing countries in the ocean economy 1.Stre
274、ngthening governance frameworks and collaboration To harness the economic potential of the ocean and ensure conservation,sustainable use and restoration of marine ecosystems,critical ocean governance and regulatory frameworks need to be put in place(OECD,20162).Few countries have comprehensive ocean
275、 strategies,and priorities for the ocean economy vary widely depending on cultural and socio-economic contexts.The oceans cultural significance,strategic role,and economic importance differ for example between different small developing island states in the Caribbean and Pacific on the one hand,and
276、countries with vast but underutilised coastlines on the other.In most cases and as a first step,encouraging improved policy coherence by refining and harmonising existing sectoral policies can effectively address complex ocean governance challenges,leveraging synergies and managing trade-offs(OECD,2
277、02513).Given the numerous challenges in ocean management highlighted in this reportfrom balancing competing commercial uses and enhancing a countrys position in the global ocean economy to combating illicit activities at seakey pragmatic actions to strengthen national ocean governance would include:
278、Establishing science-based ocean management frameworks:Over 70 countries have already developed some level of marine spatial planning(MSP)to address growing conflicts of usage along their coasts and beyond(e.g.balancing artisanal fishing ground,marine aquaculture,shipping corridors and marine protec
279、ted areas)and controlling better their waters.As a growing number of sea basins suffer from combinations of challenges,from agricultural runoffs and land-based pollution to excessive industrial ocean activities,the most effective ocean management systems are the ones based on the best available scie
280、nce,setting up control and enforcement mechanisms(Troya,Ansong and OHagan,202314).This is particularly important for marine protected areas,which provide the most socio-economic benefits when they are fully protected and monitored properly(Pike et al.,202415).More countries are moving beyond MSP to
281、implement“sustainable 33 THE OCEAN ECONOMY TO 2050 OECD 2025 ocean plans”,so that improved ocean management benefit their economic and sustainable development(Ocean Panel Secretariat,202116).Strengthening engagement in multilateral co-operation to enhance national strategic positioning:Consensus can
282、 be hard to reach internationally on many issues,however groups of like-minded countries can effectively advance a global ocean health agenda by ensuring that several key multilateral agreements come into force.International agreementssuch as the high seas governance agreement(BBNJ),the World Trade
283、Organizations(WTO)Agreement on Fisheries Subsidies,decarbonisation frameworks under the International Maritime Organization,and treaty efforts to curb plastic pollution should provide eventually transparent,enforceable rules and strengthen national strategic positioning.Several agreements are open f
284、or signature and ratification(Table 1.1).Their rapid or delayed implementation will affect the future of the ocean economy,including further national and commercial investments in selected ocean economic activities.Addressing and reducing regulatory gaps:Countries can use a range of regulatory instr
285、uments to support efficient natural resource management,with the OECD providing illustrations and tracking of these instruments for the benefit of users(OECD,202517).Reforming subsidies that risk encouraging unsustainable or illegal,unreported,and unregulated(IUU)fishing in the absence of effective
286、management,as well as investing in improving the monitoring,control and surveillance of fishing fleets are both fundamental to sustainable fisheries.Combating IUU fishing should continue with ongoing discussions at WTO and OECD contributing to this effort(OECD,202518).There are as yet no global guid
287、elines for countries engaging in seabed mining in national waters(usually in shallow waters),from sand to critical minerals,but the OECD has developed“Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas”,which provides advice as they apply to a
288、ll mineral supply chains(OECD,201619).For deep sea mining in the high seas,precautionary approaches should be applied by all to avoid irreversible damage to the ocean environment,as discussions continue within the International Seabed Authority membership.Foster proactive public-private dialogue:Gov
289、ernments should set clear policy signals and align economic incentives with sustainability objectives to encourage responsible business practices,while maintaining oversight to ensure that private-sector innovation advances social and environmental priorities.Some companies already align around comm
290、on sustainability principles(UN Global Compact,201920).As seen in Chapter 2,industry concentration plays a significant role in many ocean economic activities,with a few major players accounting for the majority of revenue generation.This is evident across sectors such as shipping,offshore oil and ga
291、s,and cruise tourism,where large corporations dominate the market.This can be an opportunity for encouraging responsible business practices amongst their peers.Table 1.1.Status of selected multilateral agreements relevant to ocean governance as of January 2025 Agreement Number of Signatures Number o

294、ure,while using advances to improve in parallel the knowledge base on ocean processes and how they are impacted by ocean economic activities and other pressures.This is a message from the analysis of the performance of ocean economic activities in recent decades(Chapter 4).Policymakers should drive
295、investments in advanced technologies while also encouraging private actors to continuously upgrade workforce skills and capabilities.Invest in advanced technologies:Policymakers should drive investments in advanced technologies,notably as part of support programmes to help different industries trans
296、ition to low carbon emissions.Much R&D is still needed in many industries including marine aquaculture,energy production and shipbuilding(OECD,202521).Further investment in ICT-intensive capital,automation,robotics,and digital solutions should be explored,as they can boost productivity as well.Stren
297、gthen workforce development in the ocean economy:Policymakers should encourage with private actors the development of long-term pipelines of talent,skills and knowledge in ocean domains of expertise,while implementing comprehensive up-skilling and re-skilling programmes(OECD,201922).Several countrie
298、s have also set up fast-track apprenticeship schemes,contributing to retain and make better use of the experience of older workers,while enhancing on-the-job training(Norwegian Ministry of Climate and Environment,202323).Regular updates of education curricula to equip workers with the tools needed f
299、or a more automated,digital world are also increasingly necessary in almost all ocean economic activities,from shipbuilding to ports operations and marine aquaculture.In addition,safety aspects will remain crucial in many ocean economic activities,from artisanal fishermen to ocean manufacturing.For
300、example,the move from conventional engine design to alternative fuel systems in shipping(especially ammonia)requires not only new engineering and maintenance expertise but also safety protocols for fuel handling.Leverage maritime clusters and innovation hubs:Policymakers should encourage the develop
301、ment and optimisation of maritime clusters and technology hubs to promote cross-industry synergies,reduce shared costs,and improve competitiveness.OECD work on ocean innovation networks has shown the advantages of cross-industry platforms for joint pre-competitive innovation(OECD,201922).Optimising
302、current practices in OECD countries would involve revisiting existing industry clusters to unlock further their potential and consider establishing new networks where gaps exist,while facilitating further exchanges among researchers from different disciplines and industry leaders.In the context of g
303、eopolitical tensions,governments must strengthen international frameworks to secure and manage technology and financial flows,ensuring access to advanced solutions.3.Enhancing sustained ocean observations and scientific research Effective decision-making in the ocean economy depends on robust,real-t
304、ime data.Strengthening ocean observation systems is crucial to addressing data gaps that limit the capacity to monitor ocean health and inform policy.Expand ocean observation networks and ocean data accessibility to inform science-based policies and sustainable management practices:ocean observation
305、s provide critical data that enhance public safety,economic efficiency,and environmental stewardship(OECD,201922).By delivering public information on coastal waters and beyond,the US National Oceanic and Atmospheric Administration(NOAA),in close coordination with private actors,informs for example d
306、ecision-making for activities such as marine navigation,fisheries management,and defence,by offering insights into ocean conditions that affect operational planning and safety measures 35 THE OCEAN ECONOMY TO 2050 OECD 2025 (Stevens,Jolly and Jolliffe,202124).Publicly-funded ocean observing networks
307、 contribute as well essential data that are then reused in many commercial products and services,multiplying the economic benefits from ocean observing(Rayner,Gouldman and Willis,201925;Jolliffe and Aben Athar,202426).Ocean data will increasingly feed new“ocean digital twins”to inform better decisio
308、n-makers,connecting oceanographic data to biodiversity hotspots and real-time traffic(Mercator,20257).Governments should invest in sustained ocean observation systems to ensure comprehensive coveragefrom seabed initial mapping to the monitoring of marine ecosystems.Joint programmes for under-observe
309、d regions such as the Southern Ocean should be as well receive more support to advance knowledge on major ocean processes(Clem et al.,202427).Promote transformative research and technologies for the ocean:In view of the many challenges,policymakers should encourage science,technology,and innovation
310、policies that prioritize ocean health and sustainable ocean uses(IOC-UNESCO,202428).This was reaffirmed at key international ministerial conferences,including the OECD Science and Technology Policy Ministerial Conference in April 2024,to better address major societal challenges such as climate chang
311、e and biodiversity loss.The OECD Agenda for Transformative Science,Technology and Innovation Policies provides a framework that would be conducive to raise the visibility of the benefits of ocean science and innovation(OECD,202429;OECD,202430).4.Expanding the integration of developing countries in t
312、he ocean economy With shifting demographics and evolving natural resource availability,many developing countries will stand to gain from greater participation in the ocean economy,and their experiences would benefit the broader community.Policy measures should support these countries in leveraging o
313、cean-based activities for sustainable growth,while protecting the marine environment on which they depend.Adopt integrated ocean strategies:Developing countries,as most of the advanced economies before them,stand to benefit from developing long-term national ocean economy strategies that balance eco
314、nomic growth with ecosystem integrity(OECD,20162).Several emerging economies have already developed or are working on long-term ocean strategies.However,few low-or lower-income countries are following suit.Also,many developing countries still need to integrate monitoring frameworks to deliver on the
315、ir objectives(OECD,202531).Lower barriers to growth:Developing countries should ideally implement as well cross-sectoral policiesincluding marine spatial planning,improved fisheries management,and sustainable tourism incentivesto improve policy coherence and set conducive environments for sustainabl
316、e growth(OECD,202513).The aims are to reduce access barriers related to finance and technology,and to improve access to policy evidence using such tools as ocean thematic accounting frameworks(Jolliffe,Jolly and Stevens,202132).On financing,development assistance should be steered to support these f
317、rameworks as recommended in the forthcoming OECD Guidance for Development Partners(OECD,202531).In parallel,there are opportunities to build or strengthen maritime clusters and ocean innovation networks in developing regions through joint publicprivate initiatives and capacity-building programmes(OE
318、CD,201922).Foster partnerships between developing and advanced economies:Continue to foster partnerships through multilateral forums and expert exchanges,thereby facilitating the transfer of knowledge,technology,and best practices.Financing issues will remain key and the OECD Guidance for Developmen
319、t Partners to enable a sustainable ocean economy transition in developing countries provides advice and recommendations to ensure that the ocean-related support is well-targeted,effective,and coherent(OECD,202531).The report The Ocean Economy to 2050 identifies both the decades-long resilience of th
320、e ocean economy and the pressing need to address its structural vulnerabilities.By strengthening governance,promoting 36 THE OCEAN ECONOMY TO 2050 OECD 2025 science and technological innovation,enhancing data collection,and ensuring the inclusion of developing countries,policymakers can lay the foun
321、dations for an ocean economy that is both economically vibrant and environmentally sustainable.This coordinated approach will be critical to creating jobs,generating revenue,and ensuring long-term ocean health in an increasingly digital and interconnected world.References Clem,K.et al.(2024),“Antarc
