    A problem structuring method for ecosystem-based management : the DPSIR modelling process

    Get PDF
    The purpose of this paper is to learn from Complex Adaptive Systems (CAS) theory to inform the development of Problem Structuring Methods (PSMs) both in general and in the specific context of marine management. The focus on marine management is important because it is concerned with a CAS (formed through the interconnection between natural systems, designed systems and social systems) which exemplifies their particularly ‘wicked' nature. Recognition of this compels us to take seriously the need to develop tools for knowledge elicitation and structuring which meet the demands of CAS. In marine management, chief among those tools is the DPSIR (Drivers - Pressures - State Changes - Impacts - Responses) model and, although widely applied, the extent to which it is appropriate for dealing with the demands of a CAS is questionable. Such questioning is particularly pertinent in the context of the marine environment where there is a need to not only recognise a broad range of stakeholders (a question of boundary critique) but also to manage competing knowledge (economic, local and scientific) and value claims. Hence this paper emphasises how a CAS perspective might add impetus to the development of a critical perspective on DPSIR and PSM theory and practice to promote a more systemic view of decision-making and policy development

    Management of the marine environment: Integrating ecosystem services and societal benefits with the DPSIR framework in a systems approach

    Get PDF
    Ever increasing and diverse use of the marine environment is leading to human-induced changes in marine life, habitats and landscapes, making necessary the development of marine policy that considers all members of the user community and addresses current, multiple, interacting uses. Taking a systems approach incorporating an understanding of The Ecosystem Approach, we integrate the DPSIR framework with ecosystem services and societal benefits, and the focus this gives allows us to create a specific framework for supporting decision making in the marine environment. Based on a linking of these three concepts, we present a set of basic postulates for the management of the marine environment and emphasise that these postulates should hold for marine management to be achieved. We illustrate these concepts using two case studies: the management of marine aggregates extraction in UK waters and the management of marine biodiversity at Flamborough Head, UK.

    Valuing conservation benefits of an offshore marine protected area

    Get PDF
    Increasing anthropogenic pressure in the offshore marine environment highlights the need for improved management and conservation of offshore ecosystems. This study scrutinises the applicability of a discrete choice experiment to value the expected benefits arising from the conservation of an offshore sandbank in UK waters. The valuation scenario refers to the UK part of the Dogger Bank, in the southern North Sea, and is based on real-world management options for fisheries, wind farms and marine protection currently under discussion for the site. It is assessed to what extent the general public perceive and value conservation benefits arising from an offshore marine protected area. The survey reveals support for marine conservation measures despite the general public's limited prior knowledge of current marine planning. Results further show significant values for an increase in species diversity, the protection of certain charismatic species and a restriction in the spread of invasive species across the site. Implications for policy and management with respect to commercial fishing, wind farm construction and nature conservation are discussed

    What is good land use? From rights to relationship

    Get PDF
    Industrial agriculture is the dominant method for feeding an increasingly urbanised world. However, a growing body of literature suggests that industrial practices are unsustainable and risk global food security. This article examines the legal–philosophical dimension of this literature and the vision of good land use promoted in both industrial and agrarian farming practices. It argues that industrial agriculture is premised on a concept of private property that promotes individual preference satisfaction, separates people from place and fragments landscape. In response, this article examines agrarian farming practices as a means of re-conceiving private property so that it is seen to embrace not only human good, but also ethics and the land itself. By re-conceiving private property as embracing these factors, private property may offer but one solution to the agricultural crisisPeter Burdonhttp://mulr.law.unimelb.edu.au/go/issues/previous-issues/-2010-volume-34/-2010-volume-34-

    Wild democracy: A biodiversity of resistance and renewal

    Get PDF
    Might the theory and practice of liberal representative democracy need to be rethought in and for the 'Anthropocene'? What resources are available when trying to orientate oneself in radical political space today? In this paper, the authors draw on varieties of anarchism and Marxism to develop a new, ecocentric political sensibility and practice, which they call 'wild democracy'. Calling for a 'biodiversity of resistance and renewal', this signifies an eco-egalitarian politics that privileges grassroots participation over parliamentary representation, with the aim of transcending capitalism and initiating a degrowth process of planned economic contraction. Focusing attention beyond the ballet box, this analysis attempts to rethink the meaning of political participation in an age of ecological crisis and deepen the understanding of what it means to be an ecological citizen today.Samuel Alexander and Peter Burdo

    Silencing of activism in Australian law

    Get PDF
    Environmental destruction and climate change are driving new waves of environmental activism. In response, govern- ments in several Australian states have enacted legislation designed to penalise and silence political protest. This article analyses Tasmania’s anti-protest laws and considers how the United Nations and scholars have reacted to them. We argue that protest suppression laws such as these reflect a neoliberal rationality which conceptualises society in market terms. This mode of thinking perceives protest as market interference rather than civic participation. Accordingly, anti- protest laws seek to secure the rights and interests of corporations to unimpeded market access.Mary Heath, Peter Burdo

    What are the costs and benefits of biodiversity recovery in a highly polluted estuary?

    Get PDF
    Biodiversity recovery measures have often been ignored when dealing with the restoration of degraded aquatic systems. Furthermore, biological valuation methods have been applied only spatially in previous studies, and not jointly on a temporal and spatial scale. The intense monitoring efforts carried out in a highly polluted estuary, in northern Spain (Nervión estuary), allowed for the economic valuation of the costs and the biological valuation of the benefits associated with a 21 years sewage scheme application. The analysis show that the total amount of money invested into the sewage scheme has contributed to the estuary's improvement of both environmental and biological features, as well as to an increase in the uses and services provided by the estuary. However, the inner and outer parts of the estuary showed different responses. An understanding of the costs and trajectories of the environmental recovery of degraded aquatic systems is increasingly necessary to allow policy makers and regulators to formulate robust, cost-efficient and feasible management decisions

    Assessing costs and benefits of measures to achieve good environmental status in European regional seas: challenges, opportunities, and lessons learnt

    Get PDF
    The EU Marine Strategy Framework Directive (MSFD) requires Member States to assess the costs and benefits of Programmes of Measures (PoMs) put in place to ensure that European marine waters achieve Good Environmental Status by 2020. An interdisciplinary approach is needed to carry out such an assessment whereby economic analysis is used to evaluate the outputs from ecological analysis that determines the expected effects of such management measures. This paper applies and tests an existing six-step approach to assess costs and benefits of management measures with potential to support the overall goal of the MSFD and discusses a range of ecological and economic analytical tools applicable to this task. Environmental cost-benefit analyses are considered for selected PoMs in three European case studies: Baltic Sea (Finland), East Coast Marine Plan area (UK), and the Bay of Biscay (Spain). These contrasting case studies are used to investigate the application of environmental cost-benefit analysis (CBA) including the challenges, opportunities and lessons learnt from using this approach. This paper demonstrates that there are opportunities in applying the six-step environmental CBA framework presented to assess the impact of PoMs. However, given demonstrated limitations of knowledge and data availability, application of other economic techniques should also be considered (although not applied here) to complement the more formal environmental CBA approach

    Differential effectiveness of residential versus outpatient aftercare for parolees from prison-based therapeutic community treatment programs

    <p>Abstract</p> <p>Background</p> <p>Research has indicated that more intense treatment is associated with better outcomes among clients who are appropriately matched to treatment intensity level based on the severity of their drug/alcohol problem. This study examined the differential effectiveness of community-based residential and outpatient treatment attended by male and female drug-involved parolees from prison-based therapeutic community substance abuse treatment programs based on the severity of their drug/alcohol problem.</p> <p>Methods</p> <p>Subjects were 4,165 male and female parolees who received prison-based therapeutic community substance abuse treatment and who subsequently participated in <it>only </it>outpatient or <it>only </it>residential treatment following release from prison. The dependent variable of interest was return to prison within 12 months. The primary independent variables of interest were alcohol/drug problem severity (low, high) and type of aftercare (residential, outpatient). Chi-square analyses were conducted to examine the differences in 12-month RTP rates between and within the two groups of parolees (residential and outpatient parolees) based on alcohol/drug problem severity (low severity, high severity). Logistic regression analyses were performed to determine if aftercare modality (outpatient only vs. residential only) was a significant predictor of 12-month RTP rates for subjects who were classified as low severity versus those who were classified as high severity.</p> <p>Results</p> <p>Subjects benefited equally from outpatient and residential aftercare, regardless of the severity of their drug/alcohol problem.</p> <p>Conclusion</p> <p>As states and the federal prison system further expand prison-based treatment services, the demand and supply of aftercare treatment services will also increase. As this occurs, systems and policies governing the transitioning of individuals from prison- to community-based treatment should include a systematic and validated assessment of post-prison treatment needs and a valid and reliable means to assess the quality of community-based treatment services. They should also ensure that parolees experience a truly uninterrupted continuum of care through appropriate recognition of progress made in prison-based treatment.</p
