People's dependence on firewood as a primary source of energy is causing serious deforestation problems in many developing countries. Reliable information on firewood consumption rates is needed to develop afforestation plans and to control deforestation. This study compares three methods used to determine firewood consumption in a Nepali village. Cultural and environmental factors that affect firewood consumption in the village are also examined.Theweight survey proved to be the most accurate method used. The less precisedaily recall andannual recall surveys overestimated actual firewood consumption by factors of 1.76 and 1.95, respectively. Overestimates are attributed to both physical and social factors. In view of the good agreement between daily and annual recall surveys, and the much greater ease of conducting the latter, annual recall surveys are recommended as the most practical method of monitoring firewood consumption rates. Validating the survey with occasional weighed measurements is suggested as a means of improving accuracy.  相似文献

Nipped in the Bud: Why Regional Scale Adaptive Management Is Not Blooming   总被引:4,自引:2,他引:4  
Adaptive management is an approach to managing natural resources that emphasizes learning from the implementation of policies and strategies. Adaptive management appears to offer a solution to the management gridlock caused by increasing complexity and uncertainty. The concept of adaptive management has been embraced by natural resource managers worldwide, but there are relatively few published examples of adaptive management in use. In this article, we explore two watershed management projects in southeastern Australia to better understand the potential of adaptive management in regional scale programs through qualitative, case study–based investigation. The program logic of one case implies the use of passive adaptive management, whereas the second case claims to be based on active adaptive management. Data were created using participant observation, semistructured interviews with individuals and groups, and document review. Using thematic content and metaphor analysis to explore the case data, we found that each case was successful as an implementation project. However, the use of both passive and active adaptive management was constrained by deeply entrenched social norms and institutional frameworks. We identified seven “imperatives” that guided the behavior of project stakeholders, and that have consequences for the use of adaptive management. Reference to recent evaluations of the Adaptive Management Areas of the Pacific Northwest of the United States suggests that some of these imperatives and their consequences have broad applicability. The implications of our findings are discussed, and suggestions for improving the outcomes of regional scale adaptive management are provided.  相似文献

Apocalyptic narratives in green politics have provoked much controversy about questions of rhetoric and framing. Critics argue that constant warnings about impending environmental collapse demoralise and demobilise the public, while advocates argue that dire predictions embody a realism necessary if the radical collective action required for a green transition is to be taken. This is not just a debate about the tactics of presentation; at a substantive ideological level, the multilayered questions raised by apocalypticism cut to the heart of significant divisions in the green movement between radical and mainstream currents concerning their orientation to structures of political and economic power. Comparisons with the contested historical tradition of apocalyptics in Christian theology shed light upon the dynamic tensions between movement insurgency and institutionalisation. Apocalypticism has played a key role in framing the green critique of capitalist modernity and is intrinsically connected to the formulation of utopic alternatives. In both theory and practice, it remains the animating spirit of radical environmentalism.  相似文献

To examine how citizen-driven initiatives for sustainability strive to bring about change and spread their practices, efforts to link social movement, grassroots innovation and green-consumption movements theory are built upon. Göteborg’s citizen-driven waste-prevention initiatives, such as food waste recovery, creating common reuse spaces in housing blocks, exchanging used toys and repairing abandoned bicycles, are considered with data from observations, workshops, documents, social media communications and in-depth interviews. Citizen-driven initiatives succeeded in mobilizing material resources, displaying and reframing various rationales, and creating collaborative local networks to develop their waste-prevention practices. These practices infiltrated the municipal administration, matching incipient institutional mandates to minimize waste. By so doing, they bring within mainstream institutions radical rationales that can become activated in the future, contributing to diachronic change.  相似文献

As Green Corporate Social Responsibility spreads across the globe, the construction industry is under pressure to reduce the carbon emissions across their building projects. Between maximum profit and environment management, mathematical programming can be used as a decision support tool concerning the optimal green building projects portfolio. This environment strategic decision problem is addressed in this study where an activity-based costing decision model incorporating carbon tax costs and construction resources constraints is developed from the perspectives of capacity expansion and green technology outsourcing. The results illustrate the positive contribution of the mathematical programming approach to achieve viable green building projects portfolio solutions. Sensitivity analyses are carried out to analyse the impact of carbon footprint emission variation on maximum profit, and the corresponding results are discussed.  相似文献

This article presents a critical reflection on the theory and practice of social sustainability in the built environment, identifies areas of agreement and disagreement, explores theoretical and conceptual gaps and challenges, and suggests practical implications for future research and urban policy. It argues that despite revisionist approaches which challenge the tripartite structure of sustainable development, social dimension of sustainability remains an essential valid pillar. Utilising a qualitative meta-analysis methodology for undertaking critical analysis of previous research and publications on the topic, key themes of theory and practice of social sustainability are identified and critically examined. Accordingly, 10 key formative characteristics of social sustainability and their research and policy implications are introduced. The article concludes with institutional observations for policy-makers to achieve greater success in addressing largely underestimated dimensions of social sustainability in urban settings.  相似文献
