In selecting six keywords from the environmental discourse the authors argue that language's 'double motivation' reveals a dialectical structure through which it simultaneously expresses both a utopian narrative and an ideologically driven myth of totality and consensus. The ambiguity of these keywords is of critical significance to all those involved in the environmental discourse, for without agreement on the meaning of commonly used concepts effective policy development is potentially disabled. The keywords we explore are 'community', 'sustainability', 'globalisation', 'diversity', 'democracy' and 'environment' itself. 相似文献

This paper explores issues that are central to ecological economics. In spite of a substantial body of research and other
literature that has appeared in recent decades on transition, and countless other efforts, no progress has been made to halt
the increase in global warming, global emissions, rampant population growth, or several hundred other critical planet sustainability
indicators including global species extinction. The opposite is true. Consumption has escalated and it is poised to double
and, with it, planetary decay has followed closely. The aim of this work is to introduce a pragmatic solution and the economics
mechanisms solidly rooted in science, in the laws of conservation of mass and energy, and in environmental and ecological
sustainability that are necessary to overcome the tremendous forces of social, political, and economic resistance to major
change. To advance towards a sustainable civilization, adopting a holistic approach with those underlying principles in all
aspects of human activity, among others economy, finance, industry, commerce, engineering, politics, architecture, and education,
is both lacking and fundamentally required. A short review of the state-of-the-art of the science on the critical status of
the planet’s resources and its life-supporting systems is presented, as well as a brief catalog of the seminal works of the
science that gave rise to its metrics and established early on the groundwork for the understanding of the degree of sustainability
of the planet. We present the argument why past and current schemes of human economics, organization, culture, and politics
cannot achieve anything else, but complete and utter failure under their own underlying precepts. A rigorous and disciplined
process on how to overcome and avoid the precipitous decline and collapse of the environmental and planetary biosystems on
which all life depends, including human life, and a new view towards the world and the universe we all have no choice but
to live in, are also offered. 相似文献

Poverty, hunger and demand for agricultural land have driven local communities to overexploit forest resources throughout
Ethiopia. Forests surrounding the township of Humbo were largely destroyed by the late 1960s. In 2004, World Vision Australia
and World Vision Ethiopia identified forestry-based carbon sequestration as a potential means to stimulate community development
while engaging in environmental restoration. After two years of consultation, planning and negotiations, the Humbo Community-based
Natural Regeneration Project began implementation—the Ethiopian organization’s first carbon sequestration initiative. The
Humbo Project assists communities affected by environmental degradation including loss of biodiversity, soil erosion and flooding
with an opportunity to benefit from carbon markets while reducing poverty and restoring the local agroecosystem. Involving
the regeneration of 2,728 ha of degraded native forests, it brings social, economic and ecological benefits—facilitating adaptation
to a changing climate and generating temporary certified emissions reductions (tCERs) under the Clean Development Mechanism.
A key feature of the project has been facilitating communities to embrace new techniques and take responsibility for large-scale
environmental change, most importantly involving Farmer Managed Natural Regeneration (FMNR). This technique is low-cost, replicable,
and provides direct benefits within a short time. Communities were able to harvest fodder and firewood within a year of project
initiation and wild fruits and other non-timber forest products within three years. Farmers are using agroforestry for both
environmental restoration and income generation. Establishment of user rights and local cooperatives has generated community
ownership and enthusiasm for this project—empowering the community to more sustainably manage their communal lands. 相似文献

EOS, or emulsified oil substrate, was used to stimulate anaerobic biodegradation of trichloroethene (TCE) and tetrachloroethene (PCE) at a former Army‐owned manufacturing facility located in the Piedmont area of North Carolina. Previous use of chlorinated solvents at the facility resulted in soil and groundwater impacts. Ten years of active remediation utilizing soil vacuum extraction and air sparging (SVE/AS) were largely ineffective in reducing the TCE/PCE plume. In 2002, the Army authorized preparation of an amended Remedial Action Plan (RAP) to evaluate in situ bioremediation methods to remediate TCE in groundwater. The RAP evaluated eight groundwater remediation technologies and recommended EOS as the preferred bioremediation alternative for the site. Eight wells were drilled within the 100 × 100 feet area believed to be the primary source area for the TCE plume. In a first injection phase, dilute EOS emulsion was injected into half of the wells. Distribution of the carbon substrate through the treatment zone was enhanced by pumping the four wells that were not injected and recirculating the extracted water through the injection wells. The process was repeated in a second phase that reversed the injection/extraction well pairs. Overall, 18,480 pounds of EOS were injected and 163,000 gallons of water were recirculated through the source area. Anaerobic groundwater conditions were observed shortly after injection with a corresponding decrease in both PCE and TCE concentrations. Dissolved oxygen, oxidation‐reduction potential, and sulfate concentrations also decreased after injection, while TCE‐degradation products, ferrous iron, and methane concentrations increased. The reduction in TCE allowed the Army to meet the groundwater remediation goals for the site. Approximately 18 months after injection, eight wells were innoculated with a commercially prepared dechlorinating culture (KB‐1) in an attempt to address lingering cis‐1,2‐dichloroethene (cis‐DCE) and vinyl chloride (VC) that continued to be observed in some wells. Dehalococcoides populations increased slightly post‐bioaugmentation. Both cis‐DCE and VC continue to slowly decrease. © 2007 Wiley Periodicals, Inc. 相似文献
