Abstract

A local sustainable development initiative to establish a temporary pedestrian zone within a Canadian urban community served as a research study into the efficacy of social capital in the development of a network for community action. This community-based initiative used social capital to overcome campaign obstacles and the campaign itself generated new social capital within the neighbourhood through the creation of adaptive networks of participants. The campaign succeeded in creating a part-time pedestrian-only space that serves as an educational example of change for sustainable community development that is replicable in other communities, and provides an example of alternative occupation of community space. Contrary to other literature, little evidence of “core burnout” was found although the network does continue to expend a large amount of effort and time on fundraising. While social capital is a powerful tool for local grassroots action, the availability of a critical source of economic capital may prove vital to the long-term success and sustainability of the network.  相似文献

This paper provides an assessment of the tools required to fulfil the air quality management role now expected of local authorities within the UK. The use of a range of pollution monitoring tools in assessing air quality is discussed and illustrated with evidence from a number of previous studies of urban background and roadside pollution monitoring in Leicester. A number of approaches to pollution modelling currently available for deployment are examined. Subsequently, the modelling and monitoring tools are assessed against the requirements of local authorities establishing air quality management areas. Whilst the paper examines UK-based policy, the study is of wider international interest.  相似文献

This article contributes to the understanding of adaptive capacity within national sectors by utilising two perspectives from institutional theory. Resting on data from 21 interviews the paper analyses the Norwegian electricity sector and the influence on adaptive capacity to climate change from changes in formal structure and institutional culture. The sector underwent transformational change between the beginning of the 1980s and mid-2000s, with the reform from 1991 as a watershed, and gradual consolidation from about 2000. From a self-regulated vertically integrated sector with an emphasis on robustness of supply the sector changed into a liberalised and unbundled structure, with economic efficiency as the guiding principle. These changes reduced adaptive capacity to climate change. After 2000, gradually adaptive capacity has increased somewhat. The paper argues that also social contextual factors need to be taken account of, both to understand adaptive capacity to climate change and to provide practitioners with an ability to increase it.  相似文献

The institutional structure and public service delivery apparatus required to meet the future effects of climate change already exist in Norway. However, there are huge challenges in coordinating these institutions at different authority levels for climate change adaptation purposes. Based upon a broad case study, this article presents how local actors consider the multi-level coordination of different levels of government and policy sectors to function today, which are the mechanisms that are used and what are the coordination challenges that are identified. Based upon the challenges revealed, this article discusses how best can the government-level institutions be organised for better goal attainment. We argue here that the elected regional level in Norway – the counties – has a huge potential to act as a multi-level coordination actor.  相似文献

Despite the apparent failure of international negotiations and renewed criticism of the accuracy of climate science, responses to climate change continue in households, cities, fields, and meeting rooms. Notions of “doing something about”, or “taking action on” or “mitigating and adapting” to climate change inform practices of carbon trading, restoring native forests, constructing wind turbines, insulating houses, using energy efficient light bulbs, and lobbying politicians for more or less of these actions. These expressions of agency in relation to climate change provide the focus of our enquiry. We found that relationships or social networks linked through local government are building capabilities to respond to climate change. However, the framework of “mitigation–adaptation” will need to be supplemented by a more diverse suite of mental models for making sense of climate change. Use of appropriate languages, cultural reference points, and metaphors embedded in diverse histories of climates and change will assist actors in their networked climate change responses.  相似文献

The different approach of specialists and general public to environmental topics has often led to contrasting positions. After decades of strong debate, however, there seems to be a growing agreement on the need for overcoming a mere contraposition in favour of an integration of opinions. This paper aims to contribute to the topic by shifting the setting into the urban environment, through the case of Pisa Municipality, Italy. It compares the scenarios described by the latest State of the Environment Report – expression of the technical evaluation – with the perception of citizens measured by a direct survey. Results were first used to investigate any disagreements about quality of environmental matrices, entity of pressures exerted on them and characteristics of determinants. They were then used to identify the range where the integration of the two positions might be pursued and finally collect, in view of future policies, indications on locally adoptable key factors and strategies.  相似文献

This paper brings together institutional theories of polycentricity and critical human geography theory on scalar politics to advance understanding of the form and function of nested, polycentric regimes for the governance of large-scale common pool resources. We focus on institutional changes associated with a national marine protected area network in Palau through which national government and NGOs gain influence in local decision-making processes. Influence is gained through an attempt to scale up common-pool resource governance to an ecologically-relevant spatial scale in an effort to protect coral reef resilience and biodiversity across Palau. An institutional approach informed by scalar politics brings into focus potential tradeoffs between organizing governance reform around ecologically versus institutionally relevant scales. Our analysis suggests that prioritization of ecologically-relevant scales in institutional reform resulted in more nested but less polycentric institutional arrangements governing the network. We conclude that less distributed decision-making in the overall nested governance system could threaten the sustainability and resilience of coral reefs in the long-term by constraining institutional innovation and diversity. Results demonstrate the potential for interdisciplinary dialog to advance the research frontier on multi-level governance for large common pool resources.  相似文献

The Monarch butterfly reserve in west-central Mexico attracts more than 250 000 visitors during the four-month annual overwintering period and yet the project has been unable to generate an impetus for local development among the indigenous and peasant communities in the region. This chapter explores the reasons for this failure and evaluates a proposed alternative development strategy. In addition to the usual problems of the paucity of local linkages, the problems involved with property rights and participation in decision-making and management suggest the need to reevaluate the model for successful and sustainable tourist development. An alternative model is presented that might contribute to overcoming the obstacles.  相似文献

In this paper we show how ideas from a longstanding but little recognised literature on adaptive governance can be used to rethink the way science supports Australian drought policy. We compare and contrast alternative ways of using science to support policy in order to critique traditional commentary on Australian drought policy. We find that criticism from narrow disciplinary and institutional perspectives has provided few practical options for policy makers managing these complex and interacting goals. In contrast, ideas from a longstanding but little recognised literature on adaptive governance have potential to create innovative policy options for addressing the multiple interacting goals of Australian drought policy.From an adaptive governance perspective, the deep concern held by Australian society for rural communities affected by drought can be viewed as a common property resource that can be sustainably managed by governments in cooperation with rural communities. Managing drought assistance as a common property resource can be facilitated through nested and polycentric systems of governance similar to those that have already evolved in other arenas of natural resource management in Australia, such as Landcare groups and Catchment Management Authorities. Essential to delivering these options is the creation of flexible, regionally distributed scientific support for drought policy capable of integrating local knowledge and informing the livelihood outcomes of critical importance to governments and rural communities.  相似文献

西南喀斯特地区石漠化问题研究综述   总被引:3,自引:0,他引:3  
喀斯特地区石漠化是在脆弱的生态地质背景基础上叠加了人类活动而出现的。西南地区的石漠化面积现仍约以2500km^2/a的速度进一步扩大。石漠化的生态治理工作的目的就是要在人为作用的干扰下,使这种逆向演替转变为顺向演替。石漠化治理思路设计的科学性、战略性、可行性决定了最后石漠化的治理结果。在喀斯特石漠化的治理中,要根据不同岩溶环境类型区及石漠化发育的不同程度和不同山地的立地条件,针对其特点,选择多种途径,运用恰当的恢复技术,制定出具体的开发治理措施,实行规模治理,以提高资源利用率,促进石漠化生态环境的综合治理。  相似文献
