This essay reflects on issues of researcher positionality within participant observation and action research, and the specific methodological issues surrounding research on neoliberal governance strategies, using my experience at the US Environmental Protection Agency as case material. Although I was initially concerned about participating with the anti-progressive Bush Administration, I attempted to adopt the interests and subjectivity of an environmental bureaucrat. Doing so proved to be an extremely effective way of exploring the multi-vocality and cross-cutting interests constituting the state, which often appears from the outside to be a policy monolith. Participant research among elites in the neoliberal state is an effective way to observe such complexity. It became apparent that, because mainstream economics tends to adopt a totalizing epistemology, both its casual and dogmatic adherents usually do not conceive of a coherent external critique. This often means that researchers of any theoretical background can be quite frank concerning their purposes, background, and interests, even as participants.  相似文献

The International Atomic Energy Agency (IAEA) organized a co-ordinated research project (CRP) on Validation and application of plants as biomonitors of trace element atmospheric pollution analysed by nuclear and related techniques involving 14 participating countries. The CRPs objective was to identify appropriate bioindicators for local and/or regional application and validate them for general air pollution monitoring. Activities included quantification studies, research into spatial and time resolution for particular organisms, and physiological studies. A number of suitable bioindicators were identified in different parts of the globe and tested during the CRP. Sampling strategies were reviewed and the recommended approach adopted by the group. Appropriate sample preparation procedures were assessed and harmonised to the degree allowed by different geographic and climatic conditions in the participating countries. Two interlaboratory comparison exercises were carried out on lichen and moss materials. Results confirmed definite improvement in analytical performance of the participating laboratories, but also revealed possible inconsistencies due to different sample processing procedures. Several monitoring surveys were carried out and consequently pollution maps drawn for extended areas or countries. Overall results confirmed applicability of lower plants for assessing the degree of atmospheric pollution and provided several countries with effective monitoring tools not used before.  相似文献

This article aims to explore the relationship between individual adaptive actions and enhancement of community resilience to climate change as a communal objective. It proposes to pay attention to the concept of reflexivity as the primary individual capacity to link adaptive actions and community resilience. Drawing on the field research conducted in northern Ghana in 2015, this article specifically examines life histories of four small farmers and shows that they individually take adaptive actions and reflect on these actions. However, little opportunity exists for them to systematically communicate the reflections with others to learn from their experiences, nurture collective agency and enhance community resilience. The article concludes by outlining new strategies needed to facilitate the communication in particular cultural and policy contexts.  相似文献

Transition to low carbon sea transport is a logical response to the extreme dependency of the Pacific Islands region on imported fossil fuel, its significant vulnerability to the effects of climate change and the critical shipping needs of Pacific Island countries (PICs). Building on previous work in low carbon sea transport in the Pacific, this paper further considers the barriers to achieving such transition by assessing, through a ‘post-Paris Agreement’ lens, the Intended Nationally Determined Contributions (INDCs) submitted by PICs and contrasting these to the near total lack of investment and planning for low carbon transition in the transport sector with the parallel occurrence in the electricity sector where ~USD 2 billion of donor investment is deployed or queued despite electricity using only ~20% of fossil fuel across the region. Consistent with recent international studies, inadequate and inappropriate financing and policy have been identified as dominant transition barriers for low carbon sea transport development in PICs. This paper further examines the regional level barriers to policy development, and finds them inhibited by the silo nature of the major regional actors. The implications that the Paris Agreement has for climate financing to support the essential research and capacity development needed to underpin a successful low carbon sea transport transition strategy at any useful scale and speed are also considered in this paper.  相似文献

In current scientific efforts to harness complementarity between resilience and vulnerability theory, one response is an ‘epistemological shift’ towards an evolutionary, learning based conception of the ‘systems-actor’ relation in social-ecological systems. In this paper, we contribute to this movement regarding the conception of stakeholder agency within social-ecological systems. We examine primary evidence from the governance of post-disaster recovery and disaster risk reduction efforts in Thailand's coastal tourism-dependent communities following the 2004 Indian Ocean Tsunami. Through an emerging storyline from stakeholders, we construct a new framework for conceptualising stakeholder agency in social-ecological systems, which positions the notion of resilience within a conception of governance as a negotiated normative process. We conclude that if resilience theory is proposed as the preferred approach by which disaster risk reduction is framed and implemented, it needs to acknowledge much more explicitly the role of stakeholder agency and the processes through which legitimate visions of resilience are generated.  相似文献

Culture plays an important role in communities’ abilities to adapt to environmental change and crises. The emerging field of resilience thinking has made several efforts to better integrate social and cultural factors into the systems-level approach to understanding social–ecological resilience. However, attempts to integrate culture into structural models often fail to account for the agentic processes that influence recovery at the individual and community levels, overshadowing the potential for agency and variation in community response. Using empirical data on the 2010 BP oil spill’s impact on a small, natural-resource-dependent community, we propose an alternative approach emphasizing culture’s ability to operate as a resource that contributes to social, or community, resilience. We refer to this more explicit articulation of culture’s role in resilience as cultural resilience. Our findings reveal that not all cultural resources that define resilience in reference to certain disasters provided successful mitigation, adaptation, or recovery from the BP spill.  相似文献

Following the well-established literature on women’s fear in urban contexts, a small but important literature has also begun to document accounts of boldness, fearlessness and empowerment. We extend this work by considering ways in which women live with, and beyond, experiences of fear. We argue that fear and fearlessness are not discrete and separate states, but rather they are often simultaneous conditions that women negotiate in complex ways. Moving away from a sense of victims and passivity, we suggest that women have spatial and social strategies that can be adopted when they face fear or take up forms of action that might be termed ‘bold’ or ‘courageous’. Consequently, this work draws on Koskela’s [Gender, Place and Culture 4 (1997) 301] previous discussion of ‘bold women’ in Finland to develop a notion of agency and highlight strategies that some rural women adopt in New Zealand.  相似文献

The film The Age of Stupid depicts the world in 2055 devastated by climate change, combining this with documentary footage which illustrates many facets of the problems of climate change and fossil-fuel dependency. This study investigates the effects of the film on UK viewers’ attitudes and behaviour through a three-stage survey. Analysis of changes in attitudes focussed particularly on respondents’ concern about climate change, motivation to act, fear about the potential for catastrophe, beliefs about responsibility for action, and sense of agency. The film increased concern about climate change, motivation to act, and viewers’ sense of agency, although these effects had not persisted 10-14 weeks after seeing it. It was also successful in promoting some mitigation actions and behavioural change, although respondents reported barriers to further action, such as limited options for improving home energy efficiency among those in rented accommodation. However, filmgoers were atypical of the general public in that they exhibited very high levels of concern about climate change, knowledge about how to reduce their carbon emissions, and contact with organisations campaigning about climate change, before they saw the film. The paper considers how these factors may have enabled viewers to respond to the film as they did, as well as policy implications for those seeking to develop effective climate change communications.  相似文献

In 2008 the US amended the century-old US Lacey Act to prohibit the import of illegally harvested or traded timber. Together with similar policies in the EU and Australia, this initialized a paradigm shift in global forest governance towards a legality (verification) regime that could substantially contribute to environmental and social stewardship in the forest sector. The analysis of the formation and implementation of these new policies in the US, Europe and Australia is, however, only just beginning.Based on 31 semi-structured interviews with key stakeholders, 19 informal conversations, more than 100 documents, and participant observation data, we analyze the policy making and implementation of the 2008 US Lacey Act amendment. Our results suggest two essential drivers for this policy change: (1) the deployment of discursive divide-and-conquer strategies and (2) a shift away from sustainability to legality, on both the international level and in the US. Based on the Discursive Agency Approach, we illustrate how carefully deployed discursive and governance strategies were crucial for building a coalition between environmentalists and parts of the wood (products) industry. This coalition was able to create a powerful storyline that muted the opposition and presented a politically attractive amendment proposal. We further show how these strategies have significant effects on the perception of the amended Lacey Act and its implementation. During implementation, coalitions as well as discursive and governance strategies shifted substantially but were still determined by the pre-amendment policy discourse. We conclude by exploring the importance of our findings for what we might expect from the concept of legality in global forest and environmental governance.  相似文献
