Local or global food markets: A comparison of energy use for transport

Abstract

This study compares energy use for food transport to a farmers' market in Sweden with energy use for transport in the conventional food system. The farmers' market was investigated through data sampling from on-site investigations. The conventional food system was studied with the aid of life cycle assessments reported in the literature. Overall, the study found no significant differences in levels of energy use for transport to the farmers' market compared with the conventional food system. For certain products, such as fresh fruits and vegetables, transport-related energy use was much lower in the local system although the season in Sweden for this kind of product is restricted to two or three months at the end of the summer. However, there is considerable potential to increase energy efficiency in local food systems by organizing the selling in new ways and by using more energy efficient vehicles.     

环境治理与地方政府——以日本公害防止协定为仍

1964年,日本横滨市政府率先和企业签订公害防止协定,由此揭开了政府和企业签署协定的序幕。协定主要涉及大气污染、水质污染、噪声、振动、恶臭和损害赔偿问题。经过多年实践,公害防止协定在很大程度上解决了公害问题,由此可见地方政府在治理公害问题上的重要性。当前我国正面临严重环境问题,各级地方政府需认真学习日本的做法,不仅要转变政府职能,更要积极主动地行动,从而加快建设资源节约型、环境友好型社会的步伐。

Learning sustainable water practices through participatory irrigation management in Thailand

Participatory irrigation management (PIM) was adopted in Thailand in 2004 to encourage the sustainable use of water in the agricultural sector. The research presented in this paper sought to understand the relationships between public participation, learning, and the implementation of more sustainable water practices through PIM in Thailand. Data was collected through document reviews, observation, informal meetings, and a total of 55 semi‐structured face‐to‐face interviews of local irrigators from two case study regions around the Krasiew Reservoir. Results showed that participating in PIM activities facilitated both instrumental (e.g., water supply and demand data, benefits of on‐time water delivery) and communicative (e.g., reasons for past PIM failure, expectations of fellow farmers) learning among PIM participants. Findings also revealed that social action is fostered through the recognition of human dignity and compassionate communication that instils a sense of ownership and solidarity among irrigators. Sustainable water practices among local farmers were spurred further through learning that the reservoir is a finite water source.     

安全信息学视域下安全舆情演化及引导策略研究*

为正确引导和控制负面安全舆情,基于安全信息学与舆情理论,利用事故树分析方法研究安全舆情演化过程,计算负面安全舆情最小割集、最小径集和结构重要度,提出安全舆情引导方法。结果表明:利用最小割集得到负面安全舆情产生原因组合,利用最小径集得到避免负面安全舆情产生最低限度事件组合,通过结构重要度得到系统改进重点及优化顺序;在事故树中增加安全舆情审核和引导组织、安全事件亲自确认、专业意见领袖3个最小径集,以期减少负面安全舆情,促进公共安全。

Places and People: Rhetorical Constructions of “Community” in a Canadian Environmental Risk Assessment

This paper addresses the issue of public engagement in environmental risk contexts through a rhetorical analysis of the key term “community” in a risk assessment of mining-caused soil contamination. Drawing on Burke's concept of terministic screens and method of cluster criticism, the analysis shows the divergent constitutions of “community” in the Sudbury Soils Study's official discourse and the citizen-activist rhetoric of the Community Committee on the Sudbury Soils Study. Tracing the verbal and visual clusters within each organization's articulation of “community” as place and people reveals how the official Study's technical-regulatory ideology of environmental risk and citizen participation is countered by the Community Committee's contestatory environmental justice ideology. These competing views of “community” are mutually constitutive in that the official Study's mainstream risk discourse establishes the terms for the Community Committee's reactive counter-discourse, thus limiting citizen participation mainly to questions of “downstream” impacts. Our rhetorical analysis of “community” suggests a generative method for understanding the complex power relations animating specific risk communication contexts as well as for potentially reinventing “community” in terms more conducive to meaningful citizen engagement.     

Environmental Capital,Negative Externality and Carbon Finance Innovation

Abstract

In the context of global climate change, the internalization of negative externality, which is brought about by the traditional mode of economic growth, has become an inevitable choice. In order to achieve the internalization, it is necessary to make innovations on the market mechanism and system, find the value of environmental capital, establish a new mode of economic growth based on environmental capital, and then transform the environmental capital, an exogenous factor of economic growth, into an endogenous factor. Of this, the key of market mechanism and system innovation is the financial innovation that is based on environmental capital and negative externality; the government defines the initial property right of environmental resources and establishes environment energy trading market, so as to guide enterprises to trade environmental resources (represented by carbon emission permit trading) based on the Clean Development Mechanism, and to vigorously develop environmental finance and carbon finance.     

火灾频发暴露我国城市公共安全系统脆弱性

为剖析近来我国火灾事故频发的原因,以上海＂11·15＂火灾事故为典型案例,分析了事件灾害过程和行为特征。结果提示：事件过程所暴露的风险管理疏失;安全基础设施薄弱;应急准备欠缺和应急响应能力不足等现象,凸显我国城市公共安全领域的系统脆弱性。系统脆弱性可能是导致＂11·15＂火灾事故发生与成灾的主要原因,作者认为系统脆弱性存在实质是公共安全体系的结构性缺陷。建议应从制度化建设入手,注意克服系统脆弱性,以加强公共安全保障能力,提高社会管理水平。     

公共部门危机学习动态过程及其知识管理研究

当前国内外对企业组织学习和危机管理的研究都已经较为成熟,在经历了几次大的危机之后,公共危机管理引起了我国许多学者的重视,但是关于高校危机学习的研究开展并不多,而国外的学者已经先一步提出了危机学习的概念并取得一些进展。随着危机种类越来越多,发生频率越来越高,高校必须要学习掌握应对危机的方法,并以此来教育学生。然而,无论是在危机管理中还是在组织学习中,知识管理都是不可或缺的一部分。因此本文以理论研究的方式,借鉴国内外学者对危机学习中知识管理的研究,希望能对高校危机学习的更深一步探索提供思路。
