Trans-nationally-scaled, multi-stakeholder, non-governmental product certification systems are emerging as important elements of neoliberal environmental governance. However, analysts question the extent to which they represent effective alternatives to the damaging impacts of neoliberalized, global production. They call for work examining the environmental politics arising in these new arenas of regulation, where social movements advocating environmental conservation and social justice interact with business interests in debates over how to use neoliberal tools to govern global commodity chains. This article examines The Forest Stewardship Council (FSC) process to revise tree plantation certification standards. First, it considers the political process surrounding standard-setting and argues that tensions between rigor, legitimacy, and acceptability restrain the political struggles over standards within voluntary, multi-stakeholder environmental governance organizations. It proffers findings at odds with the expectation that mainstreaming diminishes the rigor of social and environmental standards. Second, it speculates on the implications of this form of neoliberal environmental governance for promoting more sustainable productions of nature. The review process failed to adequately consider the role of plantation certification in strategies for natural forest conservation. Neither did it adequately consider vital questions of the appropriate scale and location of production, the community actors best suited to deliver both forest conservation and poverty alleviation, or the need to encourage reduced consumption. The reliance on a neoliberal framework and values limits the scope of action. These contradictions suggest that FSC certification is an important part of what needs to be a broader movement questioning current practices of environmentally damaging production and complicit, complacent, consumption.  相似文献

The oceans are not only being transformed through privatization as management moves towards market mechanisms, the oceans are also being “zoned”, with zoning increasingly proposed as the ideal conduit for weighting different uses of the ocean. This is concomitant with a move towards ecosystem-based management that also partakes in a policy environment imbued with the commodification of nature, in which environmental services are ranked and valued according to neoliberal percepts. Crucial to these projects are the utilization of GIS technologies. This paper considers these zones of preservation and sites of conflict through an ethnographic case study of the scallop fisheries of New England, examining conflicts between harvesters, different projects to map the fishery, and ongoing efforts to reseed scallop beds. The paper explores how participants themselves articulate the changing practices of fishing and farming, redefining boundaries of nature and culture. While reseeding projects, for example, arguably participate in the market logic of neoliberalism, at the same time they may resist and redefine the terms, as communities see themselves sowing the seeds of their own sustainability and changing the terms of what counts, literally, as nature.  相似文献

Recognition of the degraded state of rivers across the world has prompted the development of management programmes which promote river repair through rehabilitation practices. Efforts to date have emphasised concerns for biophysical attributes of rivers to the relative exclusion of socio-cultural values. Ultimately, the process of river repair must move beyond this technical focus and incorporate collective societal engagement, participation and ownership. However, the inherent complexities of informing and managing this process limit the prospects that engagement will be translated into an effective and sustained practice. This qualitative case study research analyses the community’s knowledge, views and opinions regarding geomorphic river change and river works projects undertaken in the Upper Hunter catchment, New South Wales, Australia. The responses and views expressed by the participants highlight how ineffective communication and limited understanding of past river work practices has inhibited the connection and ownership between the people and their river. Essentially, historical river management was viewed as a technical process that failed to incorporate social values and aspirations, and which gave inadequate consideration to local knowledge and experience. Participants identified the need to address both diversity and commonality in vision-building and the need for greater confidence and transparency in river science and management. In light of these responses, this paper argues for the adoption of a geo-social, transdisciplinary approach to river rehabilitation.  相似文献

Cyanobacteria (blue-green algae) blooms in water bodies present serious public health issues with attendant economic and ecological impacts. Llyn Tegid (Lake Bala) is an important conservation and amenity asset within Snowdonia National Park, Wales which since the mid-1990s has experienced multiple toxic cyanobacteria blooms threatening the ecology and tourism-dependent local economy. Multiple working hypotheses explain the emergence of this problem, including climate change, land management linked to increased nutrient flux, hydromorphological alterations or changing trophic structure - any of which may operate individually or cumulatively to impair lake function. This paper reports the findings of a sediment fingerprinting study using dated lake cores to explore the linkages between catchment and lake management practices and the emergence of the algal blooms problem. Since 1900 AD lake bed sedimentation rates have varied from 0.06 to 1.07 g cm−2 yr−1, with a pronounced acceleration since the early 1980s. Geochemical analysis revealed increases in the concentrations of total phosphorus (TP), calcium and heavy metals such as zinc and lead consistent with eutrophication and a rising pollution burden, particularly since the late 1970s. An uncertainty-inclusive sediment fingerprinting approach was used to apportion the relative fluxes from the major catchment land cover types of improved pasture, rough grazing, forestry and channel banks. This showed improved pasture and channel banks are the dominant diffuse sources of sediment in the catchment, though forestry sources were important historically. Conversion of rough grazing to improved grassland, coupled with intensified land management and year-round livestock grazing, is concluded to provide the principal source of rising TP levels. Lake Habitat Survey and particle size analysis of lake cores demonstrate the hydromorphological impact of the River Dee Regulation Scheme, which controls water level and periodically diverts flow into Llyn Tegid from the adjacent Afon Tryweryn catchment. This hydromorphological impact has also been most pronounced since the late 1970s. It is concluded that an integrated approach combining land management to reduce agricultural runoff allied to improved water level regulation enabling recovery of littoral macrophytes offers the greatest chance halting the on-going cyanobacteria issue in Llyn Tegid.  相似文献

Macroalgae has numerous commercial uses and the potential to create large carbon sinks. The study reviewed the legal context, including environmental and social aspects, for the setting up of a seaweed farm in the UK. A lease is required to use the seabed and a Marine Licence is required from the national regulator. There is no need for new legislation, however, the existing guidance should be updated. There is a major need to clarify what level of assessment is required as part of the marine licensing process. The environmental and social considerations to licensing were also reviewed. Changes to the hydrodynamics and sediment transport are expected in and around the farm. These may lead to changes in seabed siltation and light levels. The addition of hard substrate (from the anchors) and a macroalgae canopy lead to attraction of benthic animals, fish, marine mammals and birds. These, in addition to potential changes in organic matter and nutrients reaching the seabed from exudate and detritus, could create changes in existing benthic communities on the seafloor. No reason for major population-level impacts were seen. However, numerous knowledge gaps where identified. Scale appears to be an important consideration. A small farm on its own is unlikely to have a large effect on the marine environment. However, a very large farm, or multiple small farms next to each other could have a more notable effect. Knowledge gaps were identified and recommendations were provided that can assist the development of the UK macroalgae farming industry.  相似文献

The enforcement of institutional rules requires the judicial system to perform well. In the case of oil spills, courts are key actors in determining the allocation of liabilities according to international and national norms. In 2002, the Prestige oil spill led to a major environmental disaster on the coasts of Spain, France and Portugal. The limitations of liability provided by the International Regime of Civil Liability and Compensation for Oil Pollution Damage have prevented the polluters from fully compensating injured parties for the damage the spill produced. In 2013, the Spanish Provincial Court of A Coruña condemned the captain of the tanker for disobedience, but no environmental crime was found; therefore, no further civil liabilities were incurred. Nevertheless, in 2016, the Spanish Supreme Court overruled the ruling of the provincial court and proclaimed the existence of an environmental crime. This judicial rectification changed the allocation of liabilities, extended the application of the polluter-pays principle, and opened a different stage for estimating and covering the costs of the damage. This paper presents a highly relevant case study that analyses the new situation involving oil spills and the distribution of liabilities within the current international regime.  相似文献

Monetary valuation of ecosystem services enables more accurate accounting of the environmental costs and benefits of policies, but this has rarely been applied in developing countries. In such contexts, there are particular methodological and epistemological challenges that require novel valuation methodologies. This paper introduces a new participatory, deliberative choice experiment approach conducted in the Solomon Islands. The research aimed to determine the value people placed on ecosystem services and whether participatory interventions to elicit deeper held values influenced the preferences expressed. Results found that the initial willingness to pay for a number of tropical forest ecosystem services amounted to 30% of household income. Following deliberative intervention exercises, key ecosystem services effectively became priceless as participants were unwilling to trade them off in the choice experiment scenarios, regardless of financial cost. The group based deliberative approach, combined with participatory interventions, also resulted in significant learning for participants. This included a more sophisticated view of ecological-cultural linkages, greater recognition of deeper held values, and greater awareness of the consequences of human actions for the environment. The use of a group-based participatory approach instead of a conventional individual survey helped to overcome many of the practical difficulties associated with valuation in developing countries. Given the impact of learning on valuation outcomes, participation and deliberation should be integrated into valuation of any complex good, both in developing and developed economies. However, such a methodology raises questions about how valuation can deal with unwillingness to trade-off key ecosystem services, which results in the breakdown of monetary valuation methods. Evaluation of the appropriateness of valuation processes and methodologies for assessing deeper held values and use of mixed-method approaches will be essential to ensure policies take into account the extent to which human life is dependent on ecosystem services.  相似文献
