FOREWORD – 3 Foreword The ocean economy is essential to the future welfare and prosperity of humankind. It is a key source of food, energy, minerals, health, leisure and transport upon which hundreds of millions of people depend. However, the maritime industry landscape is poised to undergo a profound transition. Long considered the traditional domain of shipping, fishing and – since the 1960s – offshore oil and gas, new activities are emerging that are reshaping and diversifying maritime industries. The new “ocean economy” is driven by a combination of population growth, rising incomes, dwindling natural resources, responses to climate change and pioneering technologies. While traditional maritime industries continue to innovate at a brisk rate, it is the emerging ocean industries that are attracting most of the attention. These industries include offshore wind, tidal and wave energy; oil and gas exploration and production in ultra-deep water and exceptionally harsh environments; offshore aquaculture; seabed mining; cruise tourism; maritime surveillance and marine biotechnology. The long-term potential for innovation, employment creation and economic growth offered by these sectors is impressive. But economic activity in the ocean is also characterised by a complex variety of risks that need to be addressed. Foremost among them are those related to ocean health from over-exploitation of marine resources, pollution, rising sea temperatures and levels, ocean acidification and loss of biodiversity. Unsustainable use of the ocean and its resources threatens the very basis on which much of the world’s welfare and prosperity depend. Realising the full potential of the ocean economy, therefore, will demand responsible, sustainable approaches to its economic development. Surprisingly perhaps, given its primordial role, the ocean economy has only recently begun to garner attention and move up the international policy agenda. Numerous international organisations are involved in efforts to address the challenges of sustainable use of the ocean. The OECD – while contributing at international policy level to specific aspects of ocean-related issues such as fisheries, shipbuilding, marine biodiversity and biotechnology – has to date not turned its attention to economic activities in the ocean more broadly. This report is the first such endeavour by the OECD to consider the ocean from an economic perspective, with a view to exploring what the Organisation’s future contribution might be in supporting national and international efforts towards a more sustainable development of the ocean economy in the future. The three-year project on which this report is based grew out of a horizon scanning and scoping exercise performed in 2011 by the OECD International Futures Programme (IFP), now part of the OECD’s Directorate for Science, Technology and Innovation (DSTI). The scoping assignment was funded by a voluntary financial contribution from the Korean Maritime Institute. The scoping results were presented and discussed at a special symposium during the EXPO 2012 held in Yeosu, Korea, and fed into the 2012 Yeosu Declaration on the Living Ocean and Coast (see: http://eng.expo2012.kr/is/ps/unity bbs/bbs/selectBbsDetail.html?ispsBbsId=BBS001&ispsNttId=0000060031). THE OCEAN ECONOMY IN 2030 © OECD 2016 4 – FOREWORD The “Future of the Ocean Economy” project aimed to explore the growth prospects for the ocean economy, and its capacity for employment creation and innovation. It was designed as a cross-sectoral, cross-disciplinary foresight exercise. Particular attention has been devoted to the emerging ocean-based industries in light of their particularly high potential in terms of growth, innovation and contribution to addressing global challenges such as energy security, environment, climate change and food security. Hence, the present report examines the risks and uncertainties surrounding the future development of ocean industries, the innovations required in science and technology to support their progress, the environmental impacts of the industries, their potential contribution to green growth as well as their negative externalities, and some of the implications for planning and regulation. Finally, and looking across the future ocean economy as a whole, it explores possible avenues for action that could boost its long-term development prospects while managing the use of the ocean itself in responsible, sustainable ways. The project has been undertaken in extensive collaboration with several other parts of the OECD, notably the Environment Directorate; the Trade and Agriculture Directorate; the Economics Department; the Centre for Entrepreneurship, SMEs and Local Economic Development; the International Transport Forum; the International Energy Agency; as well as with shipbuilding and biotechnology experts within DSTI. In addition, the project team collaborated with more than 200 external experts (see Annex A). The cross-sectoral approach to the ocean economy is based on a series of ten specialised in-depth workshops, mainly hosted and funded by governments and organisations participating in the project. Most workshops were sector-specific. These comprised offshore wind, ocean renewable energy; deep-water oil and gas exploration and production; offshore aquaculture; deep-sea mining; maritime safety and surveillance; maritime tourism; marine biotechnology; marine spatial planning; and scenario building for the ocean economy. Eight of the workshops generated working papers that are being released in conjunction with the current volume (for details see Annex B). The project was supported by voluntary financial and in-kind contributions from a wide range of government departments and agencies, corporations, research institutions, foundations and international NGOs who constituted the Project Steering Group. These are listed in Annex A Their contributions are acknowledged with sincere thanks. Barrie Stevens directed the project, chaired the meetings of the Project Advisory Group and was the principal author of this report. Torgeir Edvardsen was responsible for project management and co-chaired the workshops. Anita Gibson provided technical and logistical support to the project, the meetings of the advisory group and the workshops. Anna-Sophie Liebender led the economic modelling work on the ocean industries as well as the projections of the ocean economy, and contributed several chapters. JongJune Lee and Daniel Mittendorf provided important contributions to the modelling

  • SUSTAINABLE FISHERIES and RESPONSIBLE AQUACULTURE: a Guide for USAID Staff and Partners
    SUSTAINABLE FISHERIES AND RESPONSIBLE AQUACULTURE: A Guide for USAID Staff and Partners June 2013 ABOUT THIS GUIDE GOAL This guide provides basic information on how to design programs to reform capture fisheries (also referred to as “wild” fisheries) and aquaculture sectors to ensure sound and effective development, environmental sustainability, economic profitability, and social responsibility. To achieve these objectives, this document focuses on ways to reduce the threats to biodiversity and ecosystem productivity through improved governance and more integrated planning and management practices. In the face of food insecurity, global climate change, and increasing population pressures, it is imperative that development programs help to maintain ecosystem resilience and the multiple goods and services that ecosystems provide. Conserving biodiversity and ecosystem functions are central to maintaining ecosystem integrity, health, and productivity. The intent of the guide is not to suggest that fisheries and aquaculture are interchangeable: these sectors are unique although linked. The world cannot afford to neglect global fisheries and expect aquaculture to fill that void. Global food security will not be achievable without reversing the decline of fisheries, restoring fisheries productivity, and moving towards more environmentally friendly and responsible aquaculture. There is a need for reform in both fisheries and aquaculture to reduce their environmental and social impacts. USAID’s experience has shown that well-designed programs can reform capture fisheries management, reducing threats to biodiversity while leading to increased productivity, incomes, and livelihoods. Agency programs have focused on an ecosystem-based approach to management in conjunction with improved governance, secure tenure and access to resources, and the application of modern management practices.

  • Ocean Thinki Ng
    Ocean Thinki ng The Work of Ocean Sciences, Scientists, and Technologies in Producing the Sea as Space Susannah Crockford Ⅲ ABSTRACT: How do scientists produce the ocean as space through their work and words? In this article, I examine how the techniques and tools of oceanographers con- stitute ocean science. Bringing theoretical literature from science and technology stud- ies on how scientists “do” science into conversation with fi ne-grained ethnographic and sociological accounts of scientists in the fi eld, I explore how ocean science is made, produced, and negotiated. Within this central concern, the technologies used to obtain data draw particular focus. Juxtaposed with this literature is a corpus by ocean scien- tists about their own work as well as interview data from original research. Examining the diff erences between scientists’ self-descriptions and analyses of them by social sci- entists leads to a productive exploration of how ocean science is constituted and how this work delineates the ocean as a form of striated space. Th is corpus of literature is placed in the context of climate change in the fi nal section. Ⅲ KEYWORDS: anthropology of science, climate change, oceans, oceanography, science and technology studies, sociology of science, space and place Th inking about the Ocean “When I think of climate . it’s very much shaped by, I think, my ocean thinking . ” When I asked a paleoceanographer about changes in the climate around southern Iceland, he answered by referencing ocean circulation patterns and the layering of subtropical and subpolar waters.1 What this answer highlighted was the pivotal role of the ocean in the functioning of Earth systems.

    Palau Declaration on ‘The Ocean: Life and Future’ Charting a course to sustainability Importance of the Ocean to us 1. As Leaders of the Pacific Islands Forum, we have and will continue to play a central role in the stewardship of one of the greatest natural endowments in the world – the Pacific Ocean. It is the lifeblood of our economies and societies and is crucial to global climatic and environmental stability. It is the fabric of unity upon which we have woven individual and collective relationships and agreements on sustainable development, now and into the future. The Ocean is our Life and our Future. The people of the Pacific Ocean are a living testament to that truth. Our way of life, our culture, our direction and our actions should reflect that truth, as it is our very identity: People of the Ocean. 2. The well-being of our Pacific people remains the central point of reference and convergence for our efforts to sustainably develop, manage and conserve our Pacific Ocean and its resources. This is made all the more important as many of our countries are faced with: increased dependency on imported foods; a growing Non-Communicable Disease crisis in Pacific communities; slow to moderate economic growth rates; high transport costs; fossil fuel dependency; growing urbanization; growing population rates and adverse impacts from climate change. The health and productivity of the Pacific Ocean is significant for all of these development challenges, now and into the future. Threats to the Ocean and populations 3. In our lifetime, a dangerous combination of human impacts has come to threaten the foundation of our Pacific livelihoods, which centers largely on the Pacific Ocean, and indeed those of the rest of the world.

  • International Law Enforcement Cooperation in the Fisheries Sector: a Guide for Law Enforcement Practitioners
    International Law Enforcement Cooperation in the Fisheries Sector: A Guide for Law Enforcement Practitioners FOREWORD Fisheries around the world have been suffering increasingly from illegal exploitation, which undermines the sustainability of marine living resources and threatens food security, as well as the economic, social and political stability of coastal states. The illegal exploitation of marine living resources includes not only fisheries crime, but also connected crimes to the fisheries sector, such as corruption, money laundering, fraud, human or drug trafficking. These crimes have been identified by INTERPOL and its partners as transnational in nature and involving organized criminal networks. Given the complexity of these crimes and the fact that they occur across the supply chains of several countries, international police cooperation and coordination between countries and agencies is absolutely essential to effectively tackle such illegal activities. As the world’s largest police organization, INTERPOL’s role is to foster international police cooperation and coordination, as well as to ensure that police around the world have access to the tools and services to effectively tackle these transnational crimes. More specifically, INTERPOL’s Environmental Security Programme (ENS) is dedicated to addressing environmental crime, such as fisheries crimes and associated crimes. Its mission is to assist our member countries in the effective enforcement of national, regional and international environmental law and treaties, creating coherent international law enforcement collaboration and enhancing investigative support of environmental crime cases. It is in this context, that ENS – Global Fisheries Enforcement team identified the need to develop a Guide to assist in the understanding of international law enforcement cooperation in the fisheries sector, especially following several transnational fisheries enforcement cases in which INTERPOL was involved.

Old Town Pond Overview The New York State Department of Environmental Conservation (DEC), Shinnecock Bay/Atlantic Ocean Watershed report, includes a fact sheet for Old Town Pond, an 8.5-acre pond which is assessed as an impaired waterbody. Recreational uses are considered to be impaired by frequent to persistent occurrences of harmful algal blooms. Aquatic life may also be impacted by resulting low dissolved oxygen in the pond. Nonpoint stormwater runoff, agricultural activity and residential onsite septic systems are suspected sources of pollutants. Old Town Pond was sampled in 2015 by SUNY Stony Brook as part of a harmful algae bloom collaborative with the DEC, Division of Water. Nonpoint stormwater runoff, agricultural activity and residential onsite septic systems are suspected sources of nutrients that are thought to be contributing to the algal blooms and could be resulting in low dissolved oxygen in the pond.

    WIDER Working Paper No. 2013/052 Optimum fisheries management under climate variability Evidence from artisanal marine fishing in Ghana Wisdom Akpalu1, Isaac Dasmani2, and Ametefee K. Normanyo3 May 2013 Abstract In most coastal developing countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could impact the environmental carrying capacity of the fish stock. This study investigates the effect of climate variation on biophysical parameters and yields. Our results indicate that the rising temperature is decreasing the carrying capacity. As a result, an optimum tax on harvest must reflect climate variability, as well as the congestion externality.

  • Status of the Aquatic Plant Maintenance Program in Florida Public Waters
    Status of the Aquatic Plant Maintenance Program in Florida Public Waters Annual Report for Fiscal Year 2006 - 2007 Executive Summary This report was prepared in accordance with §369.22 (7), Florida Statutes, to provide an annual assessment of the control achieved and funding necessary to manage nonindigenous aquatic plants in intercounty waters. The authority of the Department of Environmental Protection (DEP) as addressed in §369.20 (5), Florida Statutes, extends to the management of nuisance populations of all aquatic plants, both indigenous and nonindigenous, and in all waters accessible to the general public. The aquatic plant management program in Florida’s public waters involves complex operational and financial interactions between state, federal and local governments as well as private sector compa- nies. A summary of plant acres controlled in sovereignty public waters and associated expenditures contracted or monitored by the DEP during Fiscal Year 2006-2007 is presented in the tables on page 42 of this report. Florida’s aquatic plant management program mission is to reduce negative impacts from invasive nonindigenous plants like water hyacinth, water lettuce and hydrilla to conserve the multiple uses and functions of public lakes and rivers. Invasive plants infest 95 percent of the 437 public waters inventoried in 2007 that comprise 1.25 million acres of fresh water where fishing alone is valued at more than $1.5 billion annually. Once established, eradicating invasive plants is difficult or impossible and very expensive; therefore, continuous maintenance is critical to sustaining navigation, flood control and recreation while conserving native plant habitat on sovereignty state lands at the lowest feasible cost.
