Jesse McEntee 《Local Environment》2013,18(9-10):785-803
The increasingly popular local food movement in the US has experienced wide-scale buy-in on behalf of the general public as well as in academic arenas. However, there have been recent efforts to critique this movement, typically for being inequitable and unfairly geared towards those with above-average financial means. In this article, I examine local food efforts and present a new conceptualisation of food localism. While geographically localised food consumption activities are taking place, some have ideological labels attached to them, whereas others do not. What I have termed contemporary and traditional localisms exist in the same physical but different social space. The contemporary local is represented by current local food initiatives and corresponding aspirations to support local farmers and to promote sustainability through local purchasing behaviour. The traditional local, on the other hand, is similar in that it represents food growing activities that are in close geographical proximity to consumption, but lacks the motivation associated with the contemporary local's programmatic literature; instead, it is guided by a motivation to obtain fresh and affordable food. I substantiate the contemporary/traditional localism framework with qualitative fieldwork findings from Grafton County, New Hampshire, USA, and describe the practical as well as conceptual implications of this framework.  相似文献

Trophy hunting can provide economic incentives to conserve wild species, but it can also involve risk when rare species are hunted. The anthropogenic Allee effect (AAE) is a conceptual model that seeks to explain how rarity may spread the seeds of further endangerment. The AAE model has increasingly been invoked in the context of trophy hunting, increasing concerns that such hunting may undermine rather than enhance conservation efforts. We question the appropriateness of uncritically applying the AAE model to trophy hunting for 4 reasons. First, the AAE assumes an open‐access resource, which is a poor characterization of most trophy‐hunting programs and obscures the potential for state, communal, or private‐property use rights to generate positive incentives for conservation. Second, study results that show the price of hunting increases as the rarity of the animal increases are insufficient to indicate the presence of AAE. Third, AAE ignores the existence of biological and behavioral factors operating in most trophy‐hunting contexts that tend to regulate the effect of hunting. We argue that site‐specific data, rather than aggregated hunting statistics, are required to demonstrate that patterns of unsustainable exploitation can be well explained by an AAE model. Instead, we suggest that conservation managers seeking to investigate and identify constraints that limit the potential conservation role of trophy hunting, should focus on the critical governance characteristics that shape the potential conservation role of trophy hunting, such as corruption, insecure property rights, and inadequate sharing of benefits with local people.

Abstract: Open access (OA) publishing, whereby authors, their institutions, or their granting bodies pay or provide a repository through which peer‐reviewed work is available online for free, is championed as a model to increase the number of citations per paper and disseminate results widely, especially to researchers in developing countries. We compared the number of citations of OA and non‐OA papers in six journals and four books published since 2000 to test whether OA increases number of citations overall and increases citations made by authors in developing countries. After controlling for type of paper (e.g., review or research paper), length of paper, authors’ citation profiles, number of authors per paper, and whether the author or the publisher released the paper in OA, OA had no statistically significant influence on the overall number of citations per journal paper. Journal papers were cited more frequently if the authors had published highly cited papers previously, were members of large teams of authors, or published relatively long papers, but papers were not cited more frequently if they were published in an OA source. Nevertheless, author‐archived OA book chapters accrued up to eight times more citations than chapters in the same book that were not available through OA, perhaps because there is no online abstracting service for book chapters. There was also little evidence that journal papers or book chapters published in OA received more citations from authors in developing countries relative to those journal papers or book chapters not published in OA. For scholarly publications in conservation biology, only book chapters had an OA citation advantage, and OA did not increase the number of citations papers or chapters received from authors in developing countries.  相似文献

Residential lakeshore development is causing increasing pressure on the lacustrine environment. Traditional landscaping patterns produce lakes ringed with lawns at the expense of the naturally occurring shoreline habitat. In this work, we present a mathematical model to select path locations to minimize impacts on the lakeshore environment, while providing convenient access to the landowners.  相似文献

This article employs a close reading of documents related to the permitting process for the Dakota Access Pipeline (DAPL) and ensuing legal battle in order to argue that extant regulatory frameworks for environmental decision-making are insufficient to promote environmental justice outcomes. By analyzing the US Army Corps of Engineer's responses to comments made during the public comment phase of the NEPA evaluation of the DAPL, I argue that regulatory frameworks may exacerbate environmental justice concerns by incentivizing decision makers to prioritize justification for their decisions and avoiding legal battles over meaningfully engaging with communities. This finding leads me to call for more engagement with energy democracy's orientation toward community-led processes as a corrective to current regulatory systems. This article expands on extant work in environmental communication by more thoroughly investigating the flaws in extant regulatory frameworks and calling for a perspectival shift in environmental decision-making.  相似文献
