Beyond fisheries management: The Phronetic dimension

This paper has two main sources of inspiration. Firstly, building on Flyvbjerg's “Making Social Science Matter”[Flyvbjerg B. Making social science matter: why social inquiry fails and how it can succeed again. Cambridge: Cambridge University Press; 2003], I argue that the contribution of the social sciences to fisheries resource management must essentially be “phronetic” (after Aristotle's phronesis, i.e. practical wisdom), in contrast to the “scientific” (Aristotle: episteme) contribution of the natural sciences. Secondly, inspired by the recent publication “Fish for Life: Interactive Governance for Fisheries” [Kooiman J, Jentoft S, Pullin R, Bavinck M, editors. Fish for life: interactive governance for fisheries. Amsterdam: Amsterdam University Press; 2005], I hold that phronesis is basically what the notion of governance adds to management. Governance is the broader concept, inviting a more reflexive, deliberative and value-rational methodology than the instrumental, means-end oriented management concept. I claim that for interdisciplinarity to work in fisheries it is essential to recognize the fundamental methodological differences that exist between the social and natural sciences.     

Landscape-scale analysis of ecosystem risk and returns: A new tool for ICZM

Management of the coastal zone often focuses on “islands” of high value ecosystems, in terms of economic value or conservation. However, integrated management requires landscape-level analysis of all ecosystem values. The biodiversity portfolio analysis (BPA) method is derived from the logic used in share (equity) portfolio management in terms of balancing within a portfolio the returns with the risks. Optimising the returns from a share portfolio, or a suite of ecosystems in a landscape, is dependent on the relationship between the units in terms of risk and return. Three case studies are then presented to test the applicability of the BPA method at the international (North West Europe), regional (Durham Heritage Coast, UK) and local (part of South Uist, Outer Hebrides, UK) spatial scale. The Biodiversity Portfolio Analysis for NW Europe showed that risk and return were highly correlated in the studied Member States. The ranking of risk and return, with the highest first, was Ireland > UK > France=Netherlands > Belgium. For these Member States the risks to ecosystem service provision were positively correlated with GNI (r=0.97, P<0.01); suggesting that the higher the economic importance of coastal and marine resources in a Member State the more at risk the resources are. The regional and local case studies were more focussed on providing information on which to base Integrated Coastal Zone Management (ICZM) decision making; both case studies used stakeholder participation to determine risks and returns. The conclusions from these two case studies show how the BPA method can be useful in terms of setting ICZM priorities and in addressing local coastal issues. The BPA involves making a number of assumptions, however, it does provide coastal managers with a potential tool to strategically plan due to increased awareness of the interaction between the ecosystems in the portfolio.There is a need for such techniques, which involve stakeholder participation and which create objective outcomes, to support the implementation of ICZM.     

Marine ecosystem approaches to management: challenges and lessons in the United States

This study examined how the United States’ largest marine resource management agency, the National Oceanic and Atmospheric Administration (NOAA), has begun to change its management strategy away from traditional marine resource management approaches towards an Ecosystem Approach to Management (EAM). Surveys were conducted with 57 NOAA scientists and resource managers in nine NOAA programs in 8 different geographic regions across the United States in 2005. A qualitative analysis examined the attitudes and experiences of participants with respect to implementing EAM and identified four major challenges to enhancing cooperation and understanding of EAM. We conclude with recommendations for concrete initiatives that future efforts in EAM that any management agency can undertake to facilitate further ecosystem management opportunities.     

Coastal and marine resource use conflicts and sustainable development in Tanzania

A survey of coastal and marine resource use conflicts in Tanzania was carried out to highlight them, investigate their origin and finally, suggest ways of minimizing them. Although Tanzania is putting emphasis on environmental issues, including coastal zone management, integrated coastal area management has not yet been integrated into the government management structure/approach. Many conflicts are the result of sectoral approach to coastal and marine resources management, and improper or poor implementation of government policies. Additionally, the local coastal community, who are the foremost stakeholder, were most often not involved in the planning, decision and implementation of many projects and policies even those that affect them directly. Ignorance about the linkages of coastal and marine ecosystems and resources is also an important factor. I suggest that integrated coastal area management which is the foundation for sustainable development, as far as coastal and marine resources are concerned, should be integrated into the government administrative structure. A lead agency with full authority on all activities on the coastal area, including issuance of permits for environmental sensitive businesses/activities, should be nominated or established. This will reduce conflicts by bringing about national coordination of coastal area management.     

The targets of management rules for marine mammal populations require justification: A reply to

The management of anthropogenic impacts on marine mammal populations involves the setting of targets that are built on assumptions and choices. Scientific methods can be used to investigate the implications of management actions, but the choice of overall objectives and priorities lies outside science. A recent paper (Potential biological removal and other currently used management rules for marine mammal populations: A comparison in Marine Policy), summarised the characteristics of the main approaches currently used to set conservation management targets for marine mammal populations in order to provide a basis for discussion of the targets they contain. Cooke et al. (Management rules for marine mammal populations: A response to Lonergan in Marine Policy) responded, giving some important additional information about these management rules. However most of that paper's criticisms were incorrect or misplaced. Specifically, it erroneously treated an example of how PBR could be reworked, to make its abundance explicit, as a proposal to ignore uncertainty in managing populations. This paper addresses Cooke's main criticisms, and suggests that explicit justifications should be an important part of the process of setting targets for the management of marine mammal populations.     

Marine bioregional plans and implementation issues: Australia's oceans policy process

Australia's Oceans Policy, released in 1998, established a new, national approach for ecosystem-based ocean management that proposed the integration of sectoral and jurisdictional interests. Implementation was to be achieved through innovative institutions delivering ecosystem based management through Regional Marine Plans, now referred to as marine bioregional plans that are legislatively grounded via the Environment Protection and Biodiversity Conservation Act 1999 (Cth). This paper argues that the original focus of the implementation process has changed, reflecting a lack of jurisdictional integration and an environmental focus that prioritises marine protected area management. It examines where the oceans policy stands today and the policy gap in terms of the lofty aspirations of Australia's Oceans Policy and implementation efforts.     

The sustainable use and conservation of biodiversity in ABNJ: What can be achieved using existing international agreements?

While the international community debates the desirability and possible content of a new global instrument for the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction, alternative approaches to improving the application and implementation of existing agreements for the protection of biodiversity appear to have fallen off the agenda. Recent practice under existing global and regional agreements suggests that, given political will, significantly greater protections could be achieved through the more effective implementation of individual sectoral agreements. However, while single-sector measures have the potential to make a valuable contribution, ultimately only multi-sectoral, integrated, cooperative management can ensure the conservation and long-term sustainable use of marine biodiversity in ABNJ. This requires establishing mechanisms for cooperation both intra and inter-sectorally, as well as between the sectoral and global and regional conservation agreements. This paper examines recent initiatives within various sectoral and conservation treaty regimes aimed at improving their application within ABNJ as well as some of the challenges to, and options for, further and better cooperation and coordination among and between existing regimes, and it identifies a range of possible mechanisms for achieving more effective implementation and coordination among them. Greater use of existing mechanisms represents a sensible approach to making the most of existing arrangements without in any way foreclosing the possibility of the adoption of a more comprehensive, integrated global agreement for the protection of marine biodiversity in ABNJ.     

Sea ice–ocean coupling using a rescaled vertical coordinate z

Realistic representation of sea ice in ocean models involves the use of a non-linear free-surface, a real freshwater flux and observance of requisite conservation laws. We show here that these properties can be achieved in practice through use of a rescaled vertical coordinate “z^*” in z-coordinate models that allows one to follow undulations in the free-surface under sea ice loading. In particular, the adoption of “z^*” avoids the difficult issue of vanishing levels under thick ice.Details of the implementation within MITgcm are provided. A high resolution global ocean sea ice simulation illustrates the robustness of the z^* formulation and reveals a source of oceanic variability associated with sea ice dynamics and ice-loading effects. The use of the z^* coordinate allows one to achieve perfect conservation of fresh water, heat and salt, as shown in extended integration of coupled ocean sea ice atmospheric model.     

A new direction in coastal management

This paper argues for a stronger integration of marine sciences and coastal management studies that generates better formulated marine policies and viable policy implementation strategies. Integration of natural and social sciences in environmental management has surfaced as a key issue recently in the fields of sustainability science, ecosystem-based management, and social–ecological resilience. This paper promotes such trend in marine studies, and examines the rationale, progress, and examples of the integration.     

Non-sectarian scenario experiments in socio-ecological knowledge building for multi-use marine environments: Insights from New Zealand's Marine Futures project

The challenges of managing marine ecosystems for multiple users, while well recognised, has not led to clear strategies, principles or practice. The paper uses novel workshop based thought-experiments to address these concerns. These took the form of trans-disciplinary Non-Sectarian Scenario Experiments (NSSE), involving participants who agreed to put aside their disciplinary interests and commercial and institutional obligations. The NSSE form of co-production of knowledge is a distinctive addition to the participatory and scenario literatures in marine resource management (MRM). Set in the context of resource use conflicts in New Zealand, the workshops assembled diverse participants in the marine economy to co-develop and co-explore the making of socio-ecological knowledge and identify capability required for a new generation of multi-use oriented resource management. The thought-experiments assumed that non-sectarian navigation of scenarios will resource a step-change in marine management by facilitating new connections, relationships, and understandings of potential marine futures. Two questions guided workshop interactions: what science needs spring from pursuing imaginable possibilities and directions in a field of scenarios, and what kinds of institutions would aid the generation of science knowledge, and it application to policy and management solutions. The effectiveness of the thought- experiments helped identify ways of dealing with core problems in multi-use marine management, such as the urgent need to cope with ecological and socio-economic surprise, and define and address cumulative impacts. Discussion focuses on how the workshops offered fresh perspectives and insights into a number of challenges. These challenges include building relations of trust and collective organisation, showing the importance of values-means-ends pathways, developing facilitative legislation to enable initiatives, and the utility of the NSSEs in informing new governance and management directions in multi-use marine environments.     

Lessons learned from Eastern Africa: the development of policy on ICZM at national and regional levels

Coastal zones of Eastern Africa are endowed with a diversity of life forms and resources which support large populations of coastal communities. The economies of the countries in the region are dependent on these resources in the form of fisheries and coastal forest products, tourism, shipways and coastal facilities such as ports, industries and urban centers.Population growth, especially in coastal urban centers is increasing the demand for coastal and marine resources. In addition, poverty, lack of awareness and inadequate management have resulted in over exploitation of coastal and marine resources, habitat destruction including shoreline erosion as well as marine pollution. The rate of resource depletion and environmental degradation is on the increase. There is an urgent need for instituting management measure that will reverse the current trend.The governments in the region have accepted and are committed to the implementation of Integrated coastal management (ICZM) as an effective mechanism for addressing and resolving the multiplicity of issues experienced in coastal areas through sectoral coordination and collaborative approaches. However, the process has just begun and there are a number of ICZM initiatives in progress at local, national and regional levels. This paper presents the issues of the coastal zone and reviews some of the progress made to date in the implementation of ICZM.

Ecological and biological strategies of Etropus crossotus and Citharichthys spilopterus (Pleuronectiformes:Paralichthyidae) related to the estuarine plume, Southern Gulf of Mexico

Differences in the biological and ecological strategies of two tropical flatfishes, Etropus crossotus (fringed flounder) and Citharichthys spilopterus (bay whiff) are discussed. The comparative analysis was based on the seasonal distribution of relative abundance of the two species and flatfish movements utilizing estuarine plume influenced areas as part of their life cycles. Growth parameters of the von Bertalanffy equation and recruitment were estimated (FISAT software) to compare life cycle patterns. The recruitment patterns illustrate the key difference between “estuarine-dependent” and “estuarine-related” nekton strategies. Both species have a short life cycle with a continuous recruitment activity. E. crossotus is an estuarine-related species, with two recruitment pulses (winter frontal season), in the estuarine plume on the shelf. C. spilopterus is an estuarine-dependent species, with a main recruitment pulse during the rainy season in the estuarine plume, and a residual secondary pulse inside the adjacent estuarine system (Terminos Lagoon). The results show that the ecological success of these tropical coastal marine flatfish, with similar biological patterns, is based upon the sequential use (in time and space) of estuarine plume influenced habitats, suggesting that fish migration to shallow waters is related to food availability changes as a strategy towards optimum recruitment.     

The missing layer: Geo-technologies, communities, and implications for marine spatial planning

The assessment and management of marine resources is an increasingly spatial affair dependent upon emerging geo-technologies, such as geographic information systems, and the subsequent production of diverse layers of spatial information. These rapid developments are, however, focused on biophysical processes and data collection initiatives; the social landscape of the marine environment is undocumented and remains a “missing layer” in decision-making. As a result, the resource areas upon which stakeholders and communities are dependent are neither mapped nor integrated into planning processes. We report on a participatory method to map the presence of fishing communities at-sea. The lessons learned concerning the spatial representation of communities informs not only fisheries, but other sectors struggling to incorporate similarly the human dimensions of the marine environment in assessment and planning.     

A study of natural and artificially generated light hydrocarbons (C4–C13) in source rocks and petroleum fluids from offshore Mid-Norway and the southernmost Norwegian and Danish sectors

The “free” or “natural” light hydrocarbon composition obtained by thermal extraction-GC of source rock samples is compared with the light fraction generated by pyrolysis products of the kerogens. Even though there are large differences between the composition of the “free” C₄–C₁₃ hydrocarbon fraction and the same fraction generated by pyrolysis, some characteristics have been detected which can be used interchangeably for both data types. Visual inspection of gas chromatograms from thermal extracts and pyrolysates indicates that in particular the relative content of m+p xylene corresponds well between these two analytical methods. The source rock samples used are Upper Jurassic marine shales and Middle and Lower Jurassic coals and coaly shales from offshore Mid-Norway and Denmark. More detailed analysis of the data shows that the most effective parameter which can distinguish between different source rock types in both thermal extracts and pyrolysates is the m+p xylene/nC₈ ratio. This parameter has been used to derive classification diagrams for interpreting the source of light hydrocarbons of both natural petroleum fluids analysed by gas chromatography and the same fraction generated by pyrolysis of asphaltenes from the fluids.The model was first tested on 17 natural petroleum fluids from Mid-Norway since a comprehensive study of light hydrocarbon distributions already has been published. Further, the parameter was applied to correlate with asphaltene pyrolysates of the fluids from Mid-Norway and a total of 22 natural oils and condensates from the southernmost Norwegian and Danish sectors.     

Knowing in context: An exploration of the interface of marine harvesters' local ecological knowledge with ecosystem approaches to management

Marine resource crises have initiated a search for alternative approaches to resource assessment and management that has culminated in a global focus on ecosystem approaches to management (EAM). Here, the ecosystem extends to humans as drivers and recipients of ecosystem change. More specifically, attention is being paid to identifying specific qualities of local resource users' experiences and knowledge that might productively inform resource management, while also providing local users with substantial “voice” in shaping new management policies and practices. Here an evaluation is provided of the extent to which local ecological knowledge (LEK) can provide advice for an ecosystem approach to inshore coastal management, specifically, the identification of ecologically and biologically significant areas, based on the results of two comprehensive studies of coastal Nova Scotian commercial harvesters' local ecological knowledge. While spatially explicit, local ecological knowledge displays strengths and limitations that must be explicated for it to prove useful for strengthening “voice” and providing EAM inputs.

The implementation of an ecosystem approach to management within a federal government agency

This study examined how the United States’ National Oceanic and Atmospheric Administration (NOAA) has begun to implement and change its management strategy towards one of an ecosystem approach to management (EAM). In 2005, surveys were conducted with NOAA scientists and resource managers in nine NOAA programs in eight geographic regions across the United States. We quantitatively examined temporal and spatial trends in NOAA's EAM project implementation. Through a qualitative analysis of the data, we identified important lessons learned, best practices, and challenges of NOAA EAM projects. A content analysis identified three of the most frequently provided “success strategies” and include: (1) encouraging collaborations, (2) utilizing multidisciplinary approaches, and (3) identifying common priorities among constituents. We conclude with recommendations for initiatives that NOAA, and others interested in EAM, can undertake to facilitate further ecosystem management opportunities.     

Marine spatial planning: Lessons learned from the Portuguese debate

This paper presents and discusses legal, methodological and political frameworks for the development of the proposed Portuguese Marine Spatial Plan initiated in 2008. It considers lessons learned and is informed by discussions that have taken place since publication of the ‘Roadmap for Maritime Spatial Planning: Achieving Common Principles in the EU’. New goals are based on horizontal planning tools that cut across sea-related sectoral policies and support joined up policy making. It is in this context that Marine Spatial Planning (MSP) emerged as an essential process for sustainable decision making. The OSPAR Commission undertook an overview of national planning systems within its administrative boundaries, which confirmed spatial plans reduced conflicts. However, problems exist accessing good quality data and dealing with entrenched sectoral views. Furthermore, the transboundary nature of marine resources requires cooperation between neighbouring states. In 2006, Portugal developed a ‘National Sea Strategy’ that recognized the importance of developing its maritime space while valuing marine habitats and biodiversity. MSP development of the Portuguese sea commenced in 2008 and findings are now evaluated. They showed adaptation of existing tools to be possible and desirable, provided undertaken cautiously and found conceptual ambiguities were barriers to conflict resolution. Furthermore they showed management strategies should be designed and analysed on a case by case basis, recognising temporal and spatial variations.
