Seeing (and doing) conservation through cultural lenses 总被引:1,自引:1,他引:0
In this paper, we first discuss various vantage points gained through the authors’ experience of approaching conservation
through a “cultural lens.” We then draw out more general concerns that many anthropologists hold with respect to conservation,
summarizing and commenting on the work of the Conservation and Community Working Group within the Anthropology and Environment
Section of the American Anthropological Association. Here we focus on both critiques and contributions the discipline of anthropology
makes with regard to conservation, and show how anthropologists are moving beyond conservation critiques to engage actively
with conservation practice and policy. We conclude with reflections on the possibilities for enhancing transdisciplinary dialogue
and practice through reflexive questioning, the adoption of disciplinary humility, and the realization that “cross-border”
collaboration among conservation scholars and practitioners can strengthen the political will necessary to stem the growing
commoditization and ensuing degradation of the earth’s ecosystems. 相似文献

The objectives of this study were to assess the potential for using Thlaspi caerulescens as a phytoextraction plant and develop a user-advice model, which can predict the frequency of phytoextraction operation required under prescribed conditions. Pot and field trials were conducted using soil collected from a dedicated sewage sludge disposal facility. Soil amendments (sulphuric acid, potassium chloride and EDTA) intended to increase Cd solubility were also tested. Predictive models of Cd and Zn uptake were developed which were able to reproduce the observed pH-dependence of Cd uptake with an apparent maximum around pH 6. Chemical treatments did not significantly increase the uptake of Cd. The periodic use of phytoextraction with T. caerulescens to maintain soils below statutory metal concentration limits, when modern sewage sludges are repeatedly applied, seems very attractive given the non-intrusive and cost-effective nature of the process. The major limitations lie with the large-scale husbandry of T. caerulescens. 相似文献
