Beyond the social construction of nature: rethinking political economies of the environment

This paper seeks to make three contributions to the study of organic food in contemporary society. The first section examines the changing socio-political position of organics in the UK, taking a brief look at supply-chain and consumption relations. The second section of the paper addresses the realities of the organic sector as a mechanism for delivering rural development outcomes. This is conducted through the presentation of case study evidence from the dairy sector in Wales, looking at on-farm and supply-chain related economic impacts. The final section of the paper uses the agroecology model as a prism to examine the evolution of the organic movement in the UK and to highlight the variant and distinctive nature of UK organics. This is seen as placing limits on the capacity of the organic sector to act as a generator of rural development impacts. Copyright © 2001 John Wiley &; Sons, Ltd.     

Aberfan and the management of trauma

This paper is a case study of the management of post-disaster trauma in 1960s Britain. It explores the traumatic aftermath of the 1966 Aberfan disaster (where 116 children and 28 adults were killed when a colliery spoil heap collapsed on top of a school in a small Welsh mining community) which had a devastating impact on the village. The professional and voluntary services made available to help the bereaved, survivors and wider community are documented and assessed. The paper demonstrates how limited finance and the popular and professional contemporary understanding of trauma and disasters hindered those services, and how the actions of government and media had a negative impact on the community's recovery. This case study of disaster management in the 1960s illustrates many of the pitfalls that continue to haunt the response to man-made tragedies in the UK.     

Access rights for outdoor recreation in New Zealand: some lessons for open country in England and Wales

Access opportunities for outdoor recreation in New Zealand and England and Wales are classified according to their conformity with collective, citizenship or exclusion rights and their degrees of permanence. Alternative criteria for the apportionment of access rights are considered in the context of this classification. Different criteria for rights apportionment are found to be appropriate according to different circumstances in the context of pluralist provision. Policy developments in New Zealand are compared with those in England. After 150 years of a dominance of collective rights in New Zealand current policy is shifting provision towards exclusionary rights. In England, there is a policy shift in the other direction, towards collective rights. Lessons for the development of collective rights in England are drawn from the New Zealand experience in relation to styles of governance, public preferences, public cost, insurance liability and the potential of markets.     

COMPARISON OF ANNUAL AND PARTIAL DURATION SERIES FLOODS ON THE MURRUMBIDGEE RIVER1

ABSTRACT: In current hydrologic practice flood frequency estimates are usually based upon either the annual or the partial duration series of floods. Recurrence intervals generated by each series are not equivalent, however, and conversion of recurrence intervals from one series to the other is usually achieved by reference to a mathematical function developed by Langbein in 1949. Data collected on the Murrumbidgee River in New South Wales suggest, however, that the Langbein conversion function does not always provide a reliable means of comparing recurrence intervals. For discharges more frequent than the three year annual flood the Langbein function understates the discrepancy between the two sets of recurrence interval by approximately 35 percent. Langbein's own North American data appear to be consistent with those collected on the Murrumbidgee River.     

Forestry and environmental democracy: the problematic case of the South Wales Valleys

Academic arguments present a critique of representative democracy and suggest that enhanced participation of communities in the management, governance and regulation of their local environments is required. Similarly, theorists of environmental democracy suggest the possibility and desirability of community involvement. In this paper, we argue that theories of environmental democracy lack the explanatory power to address real-life relations between people and their environment. Drawing on empirical material from recent research in the forested communities of the former coalfields of the South Wales Valleys, we identify significant rigidities, inertia and barriers that stand in the way of community participation in environmental democracy. We do this by constructing a framework for critical analysis that postulates a connection between recent shifts towards post-productivism in British forestry policy and theories of environmental democracy. Our findings point to a dissonance between, on the one hand, post-productivist forestry policy and theoretical discourses of governance, participation and environmental democracy, and, on the other hand, the actual situation of people living in the communities of the Valleys forest in South Wales.

‘Contractual’ and ‘cooperative’ civic engagement: The emergence and roles of ‘flood action groups’ in England and Wales

Devolution of responsibilities is transforming how flood risk is managed in many countries. Research assessing the emergence and role of a new element in the governance of flood risk management in England explored the numerous ‘flood action groups’ that have developed over the last decade. We identified two broad categories of relationship between the public and authorities. The first displays ‘contractual’ characteristics: a level of protection provided by the authority in exchange for taxes or similar support. The second embodies a ‘collaborative’ relationship: public knowledge, social and financial resources are equal and complementary to those of authority, and seeking ‘collective security’. In general, the former were more successful than the latter, but common lessons were that success in FRM should not be defined purely as the ability to prevent flooding, but as the ability to access a variety of resources across different levels of society at different stages of flood risk management.     

Distributing power? Community energy projects' experiences of planning,policy and incumbents in the devolved nations of Scotland and Wales

Community-owned energy projects are viewed as compelling contributors towards renewable energy targets. They contribute to curtailing the use of carbon intensive energy sources, consequently aiding mitigation of climate change, and can contribute towards a sustainable, localised economy. The success and expansion of the sector varies. However, there is a lack of knowledge regarding the development of the sector between sub-state nations. This qualitative, comparative study looks at the sector in the sub-state, devolved nations of Wales and Scotland within the UK. Through a series of in-depth interviews with community energy practitioners in four case study sites in Scotland and Wales, this study shows how policy and governance practices can influence the sector and those working at grassroots level. The study shows a disparity in confidence and outlook for the sector, based on the perceived (in)effective governance in each devolved nation.     

Estimation of Regional, Local and Site-specific Profitability of Soil Conservation for the Wheat-Sheep Zone of New South Wales, Australia

Information about the net benefits of land degradation treatment is required at the relevant management level, such as regional, local or site-specific, to assist decision makers in the allocation of funds to soil conservation. In this paper, estimates of regional opportunity costs of erosion and costs of treatment are used to derive benefit-cost ratios to assess the profitability of gully erosion treatment for localities in the wheat-sheep zone of New South Wales. These results are then used to develop site-specific models which predict benefit-cost ratios of treatment from land attributes including gully length, slope, soil type and land use. These predictive models form the basis of a rapid appraisal method to aid soil conservation decisions.     

Detecting atmospheric pollution in surface soils using magnetic measurements: A reappraisal using an England and Wales database

Industrial activity such as burning of fossil fuels produces magnetically enhanced particulates. These particulates consist of coarse-grained multidomain and stable single domain magnetic minerals. Two threshold values of low field magnetic susceptibility (χ_LF) and frequency dependent susceptibility percentage (χ_FD%) discriminate ferrimagnetic minerals of these sizes and can act as a tracer of magnetic pollution. Application of the thresholds to a magnetic topsoil data set (n = 5656 across England and Wales) revealed 637 samples potentially dominated by pollution particulates. The magnetic parameters of these samples display a negative correlation with distance to urban areas and positive correlations with metals associated with anthropogenic activity (Cu, Pb, and Zn). Results of experimentation with threshold values and modelling of magnetic anomalies suggest that regional factors such as geology and potential for pedogenic secondary magnetic enhancement should be considered when setting threshold values.     

Estimating and valuing the carbon sequestered in softwood and hardwood trees, timber products and forest soils in Wales

Models of carbon storage in softwood and hardwood trees and forest soils and its emission from timber products and waste are developed and integrated with data on storage benefits to yield estimates of the value of the net carbon flux generated by afforestation. The long-term nature of the processes under consideration and the impact of varying the discount rate are explicitly incorporated within the model. A geographical information system (GIS) is used to apply carbon sequestration models to data on tree growth and soil type distribution for a large study area (the entire country of Wales). The major findings are: (1) all three elements under analysis (carbon sequestration in livewood, release from different products and waste, and storage or emission from soils) play a vital role in determining overall carbon flux; (2) woodland management has a substantial impact upon carbon storage in livewood however the choice of discount rate exerts the largest overall influence upon estimated carbon flux values; (3) timber growth rates (yield class) also have a major impact upon values; (4) tree species does affect storage values, however this is less important than the other factors listed above; (5) non-peat soils generally sequester relatively low levels of carbon. Planting upon peat soils can result in very substantial emissions of carbon which exceed the level of storage in livewood.The GIS is used to produce valuation maps which can be readily incorporated within cost-benefit analyses regarding optimal locations for conversion of land into forestry.
