The Economic Value Of Sea Otters And Recreational Tourism In A California Estuary, Jessica A. Fujii, Charles S. Colgan, Anthony Castelletto, Michelle M. Staedler, Amy G. Wolfrum, Kyle S. Van Houtan

Journal of Ocean and Coastal Economics

The recovery of marine megafauna can lead to improved ecosystem function and services, but not all stakeholders may benefit equally. Quantifying the local economic value of a species’ presence may appeal to broader range of stakeholders when developing conservation strategies. This study aims to examine the economic effect recreational activities can have on a local region, and to determine what role the presence of southern sea otters (Enhydra lutris nereis) had on the value visitors placed on the visit and the area’s preservation. We surveyed visitors to Elkhorn Slough, a small estuary in California known for diverse wildlife, …

Exploring South Korea’S Ocean Economy : The Korea National Ocean Economy Survey 2017-2019, Seokwoo Jake Choi Dr, Ju-Hyeoun Kim, Gi-Su Kim, Kwang Seo Park Dr

Journal of Ocean and Coastal Economics

As the economic contribution of the ocean and fisheries industry increases, it is essential to identify industrial characteristics and propose specialized strategies based on data. However, there has been a lack of research on the establishment of an industrial classification system that reflects the characteristics of the ocean and fisheries industry in South Korea. Therefore, this study aims to introduce the specialized classification system of the ocean and fisheries industry and, further intends to analyze industry trends using the survey data based on the classification system. For the past three years (2017-2019) 9,000 businesses were surveyed annually to estimate industry …


Investing In The New Blue Economy: The Changing Role Of International Development Organizations In Catalyzing Private Sector Investment In Support Of Regional Strategic Action Programmes For The Sustainable Development Of Coasts And Oceans, Ryan Whisnant, Veerle Vandeweerd Oct 2019

Investing In The New Blue Economy: The Changing Role Of International Development Organizations In Catalyzing Private Sector Investment In Support Of Regional Strategic Action Programmes For The Sustainable Development Of Coasts And Oceans, Ryan Whisnant, Veerle Vandeweerd

Journal of Ocean and Coastal Economics

Over the last 20 years, governments sharing common coastal and ocean ecosystems have developed and agreed on concrete regional action programs to stop and, in some cases, reverse a trend of deteriorating coastal and ocean resources. Implementation of these action programs requires significant investments by the public and private sectors alike, with the potential for substantial economic growth and enhanced social well-being. For this to happen, new institutional arrangements, technologies, and financial vehicles and asset classes are needed to mainstream innovative “blue economy” projects that have the potential to transition economies and communities to more sustainable development paths.

Blue Biotechnology, Renewable Energy, Unconventional Resources And Products As Emerging Frontiers At Sea, Sheikh Aftab Uddin, Mohammad Mahmudul Islam Oct 2019

Blue Biotechnology, Renewable Energy, Unconventional Resources And Products As Emerging Frontiers At Sea, Sheikh Aftab Uddin, Mohammad Mahmudul Islam

Journal of Ocean and Coastal Economics

Blue biotechnology, renewable energy and unconventional marine living resources are considered as emerging frontiers for enhancing ocean-based blue economy in Bangladesh. Blue biotechnology can help both fisheries and aquaculture industry by producing fish varieties that can become quicker, more beneficial, and greater with tastier flesh, by developing gene transfer technology to be used to develop the growth of fish or by using of monoclonal antibodies and DNA probes to new diagnostic strategies for pathogens. Transformation of marine bioresources (main, co-product and by-products) into food, medicine, animal feed and related bio-based items i.e. cosmetics, nutritional supplements, enzymes, agrichemicals etc could help …


Blue Economy And Climate Change: Bangladesh Perspective, Subrata Sarker, Firdaus Ara Hussain, Mohammad Assaduzzaman, Pierre Failler Oct 2019

Blue Economy And Climate Change: Bangladesh Perspective, Subrata Sarker, Firdaus Ara Hussain, Mohammad Assaduzzaman, Pierre Failler

Journal of Ocean and Coastal Economics

Blue Economy is related to economic growth through the sustainable utilization of ocean resources with technological inputs to improve livelihoods. Economically important coastal and marine resources are the main components of the Blue Economy for Bangladesh. These resources are categorized into living, non-living, renewable resources and trade and commerce. As Bangladesh is vulnerable to climate change, related extreme events are making the coastal and marine resources vulnerable which may hamper the smooth Blue Economy development in Bangladesh. Climate change extreme events include warming trend, cyclone, sea level rise, droughts, erosion, tidal surge, saline water intrusion, flood, change in precipitation trend …


Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood Jun 2019

Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood

Journal of Ocean and Coastal Economics

Disease and overfishing have led to a dramatic decline in wild populations and subsequent harvests of the eastern oyster Crassostrea virginica over the past few decades in Delaware and other states along the Atlantic Coast. However, in addition to their value as food to consumers, oysters, whether wild populations or cultured stocks, can provide ecosystem services such as nutrient removal, which may result in localized water quality improvements. Consequently, recent policies in Delaware have sought to establish and grow an oyster aquaculture industry. However, a key challenge to achieving efficient levels of industry growth and water quality improvements is that …


Any Port In A Storm: Vessel Activity And The Risk Of Iuu-Caught Fish Passing Through The World’S Most Important Fishing Ports, Gilles Hosch, Bradley Soule, Max Schofield, Trevor Thomas, Charles Kilgour, Tim Huntington Jun 2019

Any Port In A Storm: Vessel Activity And The Risk Of Iuu-Caught Fish Passing Through The World’S Most Important Fishing Ports, Gilles Hosch, Bradley Soule, Max Schofield, Trevor Thomas, Charles Kilgour, Tim Huntington

Journal of Ocean and Coastal Economics

This study assesses the risk of fish from illegal, unregulated and unreported (IUU) sources passing through the world’s most important fishing ports and explores the drivers of this risk.

Like previous studies it has attempted to rank ports and States based on landings and vessel visits reported by governments by using Automatic Identification System (AIS) positional data transmitted by fishing and fish carrier vessels to identify the locations of ports and rank them based on the frequency of visits by foreign-flagged and domestic-flagged vessels. It advances our thinking in that (i) the analysis includes an estimation of the hold capacity …


Missing The Boat? Measuring And Evaluating Local Groundfish Purchases By New England Institutions, Jeffrey K. O'Hara, Loren Mcclenachan May 2018

Missing The Boat? Measuring And Evaluating Local Groundfish Purchases By New England Institutions, Jeffrey K. O'Hara, Loren Mcclenachan

Journal of Ocean and Coastal Economics

The development of local food markets has provided a critical economic opportunity for small farms in New England. The collapse of Gulf of Maine groundfish stocks has motivated an interest in developing similar marketing opportunities for wild-caught, locally abundant seafood. Institutions, particularly schools and colleges, have been identified as a strategic entry point in the supply chain for such products. However, there has been a dearth of research on this topic. We undertake a case study that evaluates purchases of local groundfish by schools and colleges in New England. First, we analyze recently developed secondary data to assess the propensity …


Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets Jun 2017

Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets

Journal of Ocean and Coastal Economics

Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …


The Market Transfer Effect In The Hawaiian Longline Fishery: Why Correlation Does Not Imply Causation, Jason D. Scorse, Shaun Richards, Philip King Jun 2017

The Market Transfer Effect In The Hawaiian Longline Fishery: Why Correlation Does Not Imply Causation, Jason D. Scorse, Shaun Richards, Philip King

Journal of Ocean and Coastal Economics

A lot of discussion and controversy has surrounded whether the “market transfer” effect in the Hawaii longline swordfish fishery occurred during the swordfish closure of 2001-2004, because of its potential impacts on sea turtle mortality. The primary academic work in support of the market transfer effect during the closure is a paper by Rausser et al. (2009): “Unintended Consequences: The Spillover Effects of Common Property Regulations.” In this paper, the authors claim to find evidence in support of the market transfer hypothesis.To our knowledge, no analysis has yet been undertaken to assess whether this analysis is sound, and yet it …


Considerations Of Socio-Economic Input, Related Challenges And Recommendations For Ecosystem-Based Maritime Spatial Planning: A Review, Mavra Stithou Jun 2017

Considerations Of Socio-Economic Input, Related Challenges And Recommendations For Ecosystem-Based Maritime Spatial Planning: A Review, Mavra Stithou

Journal of Ocean and Coastal Economics

Socio-economics in an ecosystem-based Marine Spatial Planning (MSP) process cover a wide range from specifying socio-economic objectives, respective indicators, organising stakeholder engagement, to data, methods and tools (e.g., environmental valuation and cost-benefit analysis) for example to identify issues, assess ecosystem services, provide an insight on human behaviour and compare alternative marine plans with potentially competing goals. In addition, social principles such as that of social equity have an important role to play in achieving sustainability in marine management. However, the use of socio-economics in making the ecosystem-based MSP framework operational, poses certain challenges to researchers, regulators and policy-makers. The purpose …


Climate Change Adaptation Case Study: Benefit-Cost Analysis Of Coastal Flooding Hazard Mitigation, Will Cooper, Federico Garcia, Diana Pape, David Ryder, Ben Witherell Nov 2016

Climate Change Adaptation Case Study: Benefit-Cost Analysis Of Coastal Flooding Hazard Mitigation, Will Cooper, Federico Garcia, Diana Pape, David Ryder, Ben Witherell

Journal of Ocean and Coastal Economics

The damage Hurricane Sandy caused had far-reaching repercussions up and down the East Coast of the United States. Vast coastal flooding accompanied the storm, inundating homes, businesses, and utility and emergency facilities. Since the storm, projects to mitigate similar future floods have been scrutinized. Such projects not only need to keep out floodwaters but also be designed to withstand the effect that climate change might have on rising sea levels and increased flood risk.

In this study, we develop an economic model to assess the costs and benefits of a berm (sea wall) to mitigate the effects of flooding from …


Measurement Of The Ocean Economy From National Income Accounts To The Sustainable Blue Economy, Charles S. Colgan Aug 2016

Measurement Of The Ocean Economy From National Income Accounts To The Sustainable Blue Economy, Charles S. Colgan

Journal of Ocean and Coastal Economics

The widespread efforts to incorporate the economic values of oceans into national income accounts have reached a stage where coordination of national efforts is desirable. A symposium held in 2015 began this process by bringing together representatives from ten countries. The symposium concluded that a definition of core ocean industries was possible but beyond that core the definition of ocean industries is in flux. Better coordination of ocean income accounts will require addressing issues of aggregation, geography, partial ocean industries, confidential, and imputation is also needed. Beyond the standard national income accounts, a need to incorporate environmental resource and ecosystem …


From The Orderly World Of Frameworks To The Messy World Of Data: Canada’S Experience Measuring The Economic Contribution Of Maritime Industries, Alejandro De Maio, Christine Irwin Feb 2016

From The Orderly World Of Frameworks To The Messy World Of Data: Canada’S Experience Measuring The Economic Contribution Of Maritime Industries, Alejandro De Maio, Christine Irwin

Journal of Ocean and Coastal Economics

This paper extends the frameworks developed by Park and Kildow (2014) to explore the use of supply chains to classify and organize ocean industries. Canada’s experience with measuring the economic contribution of ocean related sectors is discussed; with particular emphasis on illustrating the supply chain approach and of highlighting the multiple practical challenges that arise in defining and measuring the ocean economy. The overall conclusion is that Canada has succeeded in developing a methodological framework that allows it to report, on an annual basis high level estimates of gross domestic product, employment and labour income generated directly and indirectly by …


The New Blue Economy: The Future Of Sustainability, Mark J. Spalding Feb 2016

The New Blue Economy: The Future Of Sustainability, Mark J. Spalding

Journal of Ocean and Coastal Economics

The world’s ocean is the world’s life support. Many human activities have defined a negative relationship with the ocean. Simply put: we dump too much bad stuff in, and we take too much good stuff out. The traditional ocean economy—those ocean-based and ocean-related activities from which humans derive economic benefit— did not acknowledge or honor the ocean’s natural services, nor its finite capacity to take human abuse without undermining those services on which we depend. The “new blue economy” is the term of art for identifying those activities that improve the human relationship with the ocean and for aligning our …


Economic Assessment Of Oceans For Sustainable Blue Economy Development, Maria Corazon M. Ebarvia Feb 2016

Economic Assessment Of Oceans For Sustainable Blue Economy Development, Maria Corazon M. Ebarvia

Journal of Ocean and Coastal Economics

This paper presents the common approach on blue economy assessment adopted by selected countries in the East Asian Seas region, and results of initial assessment studies. There are many discourses on the definition and scope of blue economy as the ocean space is evolving, driven by innovations, shifting demands, and pressures from changing environment and climate. The ocean economy contributes to the GDP of the EAS countries in varying degrees: 3 % in RO Korea, 4.5 % in the Philippines, 9 % in China, and 13 % in Indonesia. In addition to the ocean economic activities, the ocean also generates …


Ocean Economy Valuation Studies In The Asia-Pacific Region: Lessons For The Future International Use Of National Accounts In The Blue Economy, Alistair Mcilgorm Feb 2016

Ocean Economy Valuation Studies In The Asia-Pacific Region: Lessons For The Future International Use Of National Accounts In The Blue Economy, Alistair Mcilgorm

Journal of Ocean and Coastal Economics

There have been several projects that have addressed the challenges of measuring the ocean economy in the Asia-Pacific region. The paper examines some lessons from these projects and the implications for the future use of national accounts.

Following the Asia Pacific Economic Cooperation (APEC) Bali declaration, the APEC Marine Resource Conservation Working group’s “Measuring the Marine economy” project promoted consistent measurement of the marine economy across the 21 APEC economies against a list of agreed marine industry categories which was developed by an APEC workshop on Easter Island in 2004.

In 2008-09 a Partnership for the Environmental Management of the …


Accounting For The Ocean Economy Using The System Of National Accounts, Raymundo J. Talento Feb 2016

Accounting For The Ocean Economy Using The System Of National Accounts, Raymundo J. Talento

Journal of Ocean and Coastal Economics

The increasing importance to measure the ocean economy cannot be discounted. A number of countries attempted to measure the ocean economy based on their needs and perceptions. At this point, however, there is no agreed scope and coverage of the ocean economy nor is there an agreed operational definition of the variables needed for its measurement. Moreover, there is no internationally endorsed framework that will guide and lead to comparable estimates across countries or regions.

Utilizing the 2008 System of National Accounts (SNA) as a framework, this paper endeavors to estimate the contribution of the ocean economy in the Philippines …


A Statistical Assessment Of Maritime Socioeconomic Indicators For The European Atlantic Area, Javier Fernandez-Macho Feb 2016

A Statistical Assessment Of Maritime Socioeconomic Indicators For The European Atlantic Area, Javier Fernandez-Macho

Journal of Ocean and Coastal Economics

Ever since the introduction into marine and maritime policy strategies worldwide of the relatively new concept of Blue Growth there has been an increasing interest in developing integrated systems of indicators for the maritime economy.

The Marnet project has been a recent attempt to develop a comparative maritime socioeconomic framework for the European Atlantic area and its database contains a large number of socioeconomic indicators for many maritime activities at different territorial levels that provide the information needed to help analyze and compare the maritime economy of the European Atlantic regions.

However, there are still many gaps with respect to …


The Role Of Economics In Ecosystem Based Management: The Case Of The Eu Marine Strategy Framework Directive; First Lessons Learnt And Way Forward., Soile Oinonen, Tobias Börger, Stephen Hynes, Ann Katrin Buchs, Anna-Stiina Heiskanen, Kari Hyytiäinen, Tiziana Luisetti, Rob Van Der Veeren Feb 2016

The Role Of Economics In Ecosystem Based Management: The Case Of The Eu Marine Strategy Framework Directive; First Lessons Learnt And Way Forward., Soile Oinonen, Tobias Börger, Stephen Hynes, Ann Katrin Buchs, Anna-Stiina Heiskanen, Kari Hyytiäinen, Tiziana Luisetti, Rob Van Der Veeren

Journal of Ocean and Coastal Economics

The EU Marine Strategy Framework Directive (MSFD) sets out a plan of action relating to marine environmental policy and in particular to achieving ‘good environmental status’ (GES) in European marine waters by 2020. Article 8.1 (c) of the Directive calls for ‘an economic and social analysis of the use of those waters and of the cost of degradation of the marine environment’. The MSFD is ‘informed’ by the Ecosystem Approach to management, with GES interpreted in terms of ecosystem functioning and services provision. Implementation of the Ecosystem Approach is expected to be by adaptive management policy and practice. The initial …


Maritime Accounts In The European Union: Coping With Limited Information, Regis Kalaydjian Feb 2016

Maritime Accounts In The European Union: Coping With Limited Information, Regis Kalaydjian

Journal of Ocean and Coastal Economics

The European Commission's effort to define the scope and components of the maritime economy was initially motivated by the "Integrated Maritime Policy" (2007). This policy package, principally based on coastal environment protection, maritime safety and security, and the European marine observation and data network, also included the development of an EU-wide economic and social database on maritime activities. The IMP database (2009) used experience from EU member states in terms of maritime database development, and conversely was an opportunity to update national contributions.

Later, two other packages contributed to broadening EC's approach. 1) The "Marine Strategy Framework Directive" (2008) was …

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill Oct 2015

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill

Journal of Ocean and Coastal Economics

In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …


Artificial Reef Attributes And The Relationship With Natural Reefs: Evidence From The Florida Keys, William L. Huth, O. Ashton Morgan, Paul Hindsley Oct 2015

Artificial Reef Attributes And The Relationship With Natural Reefs: Evidence From The Florida Keys, William L. Huth, O. Ashton Morgan, Paul Hindsley

Journal of Ocean and Coastal Economics

Natural or coral reefs represent extremely valuable ecosystems supporting an estimated 25 percent of all marine life, yet recent reports suggest that 75 percent of the world’s natural reefs are under threat from both natural and human stressors. In areas such as the Florida Keys that boasts an expansive mix of natural and artificial reefs, recreational diving on the system provides an important economic contribution to the local community but also potentially contributes to the stress of the existing natural reef system. We develop a revealed and stated preference modeling framework of diver behavior and find that deployment of an …


Economic Valuation Of Marine And Coastal Ecosystems: Is It Currently Fit For Purpose?, Nick Hanley, Stephen Hynes, David Patterson, Niels Jobstvogt Oct 2015

Economic Valuation Of Marine And Coastal Ecosystems: Is It Currently Fit For Purpose?, Nick Hanley, Stephen Hynes, David Patterson, Niels Jobstvogt

Journal of Ocean and Coastal Economics

In this paper, we consider whether the current “state of the art” of environmental valuation is suitable for producing policy-relevant estimates of the benefits or costs of changes in marine and coastal ecosystems. We review recent changes in European legislation which has meant an increasing demand for economic valuation from the policy and regulatory community. The next section considers, at a more conceptual level, whether the economic “toolbox” and scientific evidence is up to the task of meeting the demand for more evidence-based policy. Finally, three case studies are used to explore the nature of the valuation task and review …
