The overall objective of this discussion paper is to advance the knowledge on rural livelihoods in Stung Treng, Cambodia. In a cluster analysis, five clusters with very different livelihood strategies are identified based on a sample of 600 rural households. Despite the fact that nearly all households are engaged in some form of subsistence farming, especially by growing rice, the richer clusters build on self-employment and higher-skilled wage employment. In contrast the middle income cluster mainly depends on natural resources (fish and firewood). The poorer two clusters are engaged in lowerskilled wage employment. The incidence of poverty is widespread but differences between the clusters are clearly visible. Even the better-off households have consumption poverty headcount ratios of between 37 to 50% at PPP $1.25. For households from the poorest clusters the poverty headcount ratio amounts to even 70% for income and 80% for consumption. Especially the households largely depending on natural resource extraction are characterized by a high incidence of poverty and high vulnerability. In addition, there are a number of pressures which are expected to increase poverty problems in the future. Policies aimed at reducing poverty and improving rural livelihoods need to carefully consider the close linkages between rural livelihoods and natural resources. But also a diversification away from natural resource extraction into higher-skilled jobs is found to be a strategy opening up new opportunities to improve livelihood security and raise the living standards of the poor.
本讨论文件的总体目标是促进对柬埔寨上丁农村生计的了解。在聚类分析中,根据600个农村家庭的样本,确定了五个具有非常不同生计战略的聚类。尽管几乎所有家庭都从事某种形式的自给农业,特别是种植水稻,但较富裕的集群建立在自营职业和高技能工资就业的基础上。相比之下,中等收入群体主要依赖自然资源(鱼和柴火)。较贫穷的两个群体从事低技能工资的工作。贫穷的发生率很普遍,但不同类别之间的差异也很明显。即使是较富裕的家庭,按1.25美元的购买力平价计算,其消费贫困人口比率也在37%至50%之间。对于来自最贫困集群的家庭,贫困人口比例在收入方面甚至达到70%,在消费方面达到80%。特别是在很大程度上依赖自然资源开采的家庭,其特点是贫困率高,脆弱性高。此外,还有一些压力,预计将来会增加贫穷问题。旨在减少贫困和改善农村生计的政策需要仔细考虑农村生计与自然资源之间的密切联系。但也发现,从自然资源开采转向高技能工作的多样化是一种战略,为改善生计保障和提高穷人的生活水平开辟了新的机会。

The concept of environmental migrants occurs frequently in the policy debate, in particular with regard to climate change and the incidence of such migration in low-income countries. This article reviews the economic studies of environmentally induced migration. It includes recent empirical analyses that try to link environmental change to migration flows and the spatial distribution of population. A consensus seems to emerge that there is little likelihood of large increases in international migration flows due to climate variability. The evidence to date shows that regional migration will be affected, however, either on the African continent or internally, within country borders. Theoretically, environmentally induced migration can be analyzed using different frameworks: the classical Harris-Todaro model of rural-urban migration, new economic geography models, models grounded in environmental economics of pollution externalities with free factor mobility, and the new economics of labor migration. I review some of the latest attempts to analyze environmentally induced migration theoretically and the policy-relevant conclusions that can be drawn.
环境移徙者的概念经常出现在政策辩论中,特别是关于气候变化和低收入国家这种移徙的情况。本文综述了环境移民的经济学研究。它包括最近的实证分析,试图将环境变化与移民流动和人口的空间分布联系起来。一种共识似乎正在形成,即由于气候变化,国际移民流动几乎不可能大幅增加。然而,迄今为止的证据表明,区域移徙将受到影响,无论是在非洲大陆还是在国家边界内。从理论上讲,环境导致的移民可以使用不同的框架进行分析:农村-城市迁移的经典哈里斯-托达罗模型、新经济地理学模型、基于环境经济学的污染外部性与自由要素流动的模型,以及劳动力迁移的新经济学。我回顾了一些从理论上分析环境导致的移民的最新尝试,以及可以得出的与政策相关的结论。

The Emergence of Benefit-Sharing Under the Climate Regime: A Preliminary Exploration and Research Agenda 气候制度下利益分享的出现:初步探索与研究议程
Pub Date : 2014-11-14 DOI: 10.2139/SSRN.2524335

This paper analyzes the increasing currency of benefit-sharing in the climate regime and its potential to contribute to engendering greater equity in climate governance. Though benefit-sharing is not explicitly mentioned in the UN Framework Convention on Climate Change or in the Kyoto Protocol, the international climate regime raises a host of equity questions that have been at least in part addressed by making explicit or implicit reference to the notion of benefit-sharing. This paper maps the use of the benefit-sharing notion in the climate regime, with the objective of developing a research agenda towards ascertaining whether there is any overall coherence in the way it has been termed and interpreted, as well as its potential to better integrate human rights and environmental objectives in climate governance. In order to achieve this, the paper first introduces the main equity questions arising in the climate regime at the inter- and the intra-State levels, to then analyze them through a benefit-sharing lens. The conclusions articulate a series of research questions for further investigation, as well as a preliminary reflection on the implications of investigating equity in the climate regime from a benefit-sharing perspective.
本文分析了气候制度中利益分享的日益流行,及其有助于在气候治理中实现更大公平的潜力。尽管《联合国气候变化框架公约》或《京都议定书》没有明确提到利益分享,但国际气候机制提出了一系列公平问题,这些问题至少在一定程度上通过明确或暗示地提及利益分享的概念得到了解决。本文描绘了利益分享概念在气候制度中的使用情况,其目的是制定一项研究议程,以确定其命名和解释方式是否存在任何总体一致性,以及其在气候治理中更好地将人权和环境目标结合起来的潜力。为了实现这一目标,本文首先介绍了国家间和国家内部气候制度中出现的主要公平问题,然后从利益分享的角度对其进行分析。这些结论阐明了一系列有待进一步调查的研究问题,以及对从利益分享的角度调查气候制度公平性的影响的初步反思。

On February 2011, the European Commission adopted a new strategy to improve measures and access to raw materials, considering that EU is high dependence of imports of them. The new strategy considers three pillars to improving raw materials access. One of them is boosting resource efficiency and promotes recycling. This paper contains a valuable methodology applicable to some materials substitution based on Life Cycle Analysis. We consider that substitution is a multidisciplinary problem in nature dealing with Multicriteria decision making aid. The problem considers the role of energy use in sustainable development and the potential sources to increase energy efficiency during life cycle use of some materials used in a day to day basis. A set of criteria to make decisions for choosing alternative materials in the substitution process will be among other: Exergy loss, Green House Gases emissions, real energy flows and material balances needed to the chain of manufacturing processes in the production chain and the whole added value. Nevertheless, thinking in alternative materials to substitute the actual ones, it is necessary to look forward. That’s why we will also use some other tools in order of complain a set of alternative materials for a long term use, as the prospective & systems dynamics techniques.
2011年2月,考虑到欧盟对原材料进口的高度依赖,欧盟委员会采取了一项新战略,以改善措施和获取原材料的途径。新战略考虑了改善原材料获取的三大支柱。其中之一是提高资源效率,促进回收利用。本文包含了一种有价值的方法,适用于基于生命周期分析的材料替代。我们认为替代本质上是一个涉及多准则决策援助的多学科问题。这个问题考虑到能源使用在可持续发展中的作用以及在日常使用的一些材料的生命周期使用期间提高能源效率的潜在来源。在替代过程中选择替代材料的一套决策标准将包括:火能损失、温室气体排放、实际能量流和生产链中制造过程链和整个附加值所需的材料平衡。然而,用替代材料来代替实际材料的思考,是有必要向前看的。这就是为什么我们还会使用一些其他的工具来抱怨一套长期使用的替代材料,作为前瞻性和系统动力学技术。

The Dangers of Carbon Reduction Tunnel Vision 碳减排的危险是目光短浅
Pub Date : 2014-11-03 DOI: 10.2139/SSRN.2518613
Maria Savasta-Kennedy
"Tunnel vision" is a double-edged sword. It can be a positive force, focusing attention and creating momentum to act. Vice President Gore shared the 2007 Nobel Peace Prize with the IPCC when he helped focus the world’s attention on climate change and the urgent need to bring people and resources to bear on addressing the crisis. Nearly a decade later, we struggle to make Gore’s message heard: the enormity and complexity of the climate challenges facing us — facing our planet, our cultural and political systems, our legal regimes, our moral constructs — demand attention and action now. However, there exists a tension between the pressing need for action and the importance of making well-considered choices. Tunnel vision is a dangerous lens through which to view potential solutions to climate change. It is a form of selective attention which can lead to inadequate problem-formulation, partial solutions to complex problems, and unintended side effects. Tunnel vision as an approach to the multifaceted problem of climate change limits our strategies for mitigating and adapting to the warming of the planet and, ultimately, fosters additional problems.This paper speaks to the need to identify and consider the co-benefits and co-detriments (the side effects) of the climate change policies and projects we consider, particularly given the magnified impact of climate change and climate change policies on vulnerable populations.
“视野狭窄”是一把双刃剑。它可以是一种积极的力量,集中注意力,创造行动的动力。副总统戈尔与政府间气候变化专门委员会共同获得2007年诺贝尔和平奖,因为他帮助把全世界的注意力集中在气候变化以及调动人力和资源来解决这一危机的迫切需要上。近十年后,我们努力让戈尔的信息被听到:我们所面临的气候挑战的艰大性和复杂性——我们的星球、我们的文化和政治体系、我们的法律制度、我们的道德建构——需要现在就予以关注和采取行动。然而,在迫切需要采取行动和作出深思熟虑的选择的重要性之间存在着一种紧张关系。通过狭隘的眼光来看待气候变化的潜在解决方案是一种危险的视角。它是一种选择性关注的形式,可能导致问题的不充分表述,复杂问题的部分解决方案和意想不到的副作用。作为解决气候变化这一多方面问题的一种方法,狭隘的眼光限制了我们减缓和适应地球变暖的战略,并最终催生了更多的问题。本文指出,需要识别和考虑我们所考虑的气候变化政策和项目的共同利益和共同损害(副作用),特别是考虑到气候变化和气候变化政策对弱势群体的放大影响。

This report pursues three complementary aims. Firstly, it presents the first generation of country case studies on social protection systems in Latin America and the Caribbean, published in the ECLAC Project Documents collection; and it provides justifications for developing such systems. Secondly, it sets out a classificatory approach to social protection system in the region, which aims to provide a comparative basis for interpreting national cases. Lastly, using standardized data and case studies, it identifies major trends in the changes the region is undergoing in terms of social protection.
本报告追求三个相辅相成的目标。首先,它介绍了关于拉丁美洲和加勒比社会保护制度的第一代国家案例研究,发表在拉加经委会项目文件集中;它为开发这样的系统提供了理由。其次,对该地区的社会保障制度进行了分类分析,旨在为各国案例的解释提供比较依据。最后,利用标准化数据和案例研究,它确定了该区域在社会保护方面正在经历的变化的主要趋势。

Micro finance plays a vital role in reducing poverty since it paves way for employment and empowerment which leads to economic development. Empowerment, poverty reduction and development are interrelated and interdependent. Empowerment leads to economic development which results in poverty reduction and sustainable development and micro finance through SHG is considered as a tool for empowerment. The purpose of this paper is to critically analyse the real impact of microfinance on the changes in income, expenditure and consumption pattern in rural households, empowerment of women and constraints. The study reported that there is a significant increase in income, expenditure and consumption pattern and there is an appreciable empowerment in political space than economic empowerment and negligible social empowerment of women as result of participating in micro finance through SHG programme. Delay in sanction of loan and inadequacy of the loan amount are the major challenge.
小额信贷在减少贫困方面发挥着至关重要的作用,因为它为就业和赋权铺平了道路,从而促进经济发展。赋权、减贫和发展是相互关联和相互依存的。赋权带来经济发展,从而减少贫困和实现可持续发展,通过SHG提供小额融资被认为是赋权的一种工具。本文的目的是批判性地分析小额信贷对农村家庭收入、支出和消费模式变化、赋予妇女权力和制约因素的实际影响。该研究报告说,收入、支出和消费模式都有显著增加,妇女通过SHG方案参与小额融资,在政治领域的赋权明显大于经济领域的赋权,而在社会领域的赋权则微不足道。贷款审批延迟和贷款金额不足是主要挑战。

The Efficacy of Private Voluntary Certification Schemes: A Governance Costs Approach 私人自愿核证计划的成效:管治成本方法
Pub Date : 2014-10-22 DOI: 10.2139/ssrn.2513254

What are the conditions under which private, voluntary certification programs like the Rainforest Alliance or Fairtrade can successfully promote environmental and social standards? We propose that the efficacy of a certification program depends on three variables: its sustainability standards, enforcement mechanisms and its market proliferation. The stricter the standards, the better the enforcement systems and the bigger the market share, the higher will be the factual impact of a particular certification program. We develop an index to systematically compare the strengths of norms and enforcement systems across a selection of important certification schemes in the global coffee industry and collect data about their market shares. We use a qualitative comparative analysis (QCA) to analyze these data. Our results show: certification schemes with strict standards and enforcement systems possess only insignificant market shares. Certification schemes with more significant market shares have either loose standards and/or ineffective enforcement systems. We develop a governance costs approach to explain these findings. Stricter standards and enforcement systems lead to an increase of production costs. The extents to which these costs can be shifted to the market are limited. Certification schemes therefore have incentives to reduce these costs in order to increase their market shares. The results confirm that the capacity of voluntary governance schemes is systematically restricted.
在什么条件下,像热带雨林联盟或公平贸易这样的私人自愿认证项目才能成功地提高环境和社会标准?我们认为,认证计划的有效性取决于三个变量:可持续性标准、执行机制和市场扩散。标准越严格,执行体系越完善,市场份额越大,特定认证项目的实际影响就越高。我们开发了一个指数,系统地比较了全球咖啡行业中一系列重要认证计划的规范和执行系统的优势,并收集了有关其市场份额的数据。我们使用定性比较分析(QCA)来分析这些数据。我们的研究结果表明:具有严格标准和执行体系的认证方案所占的市场份额微不足道。市场份额较大的认证制度要么标准松散,要么执行制度无效。我们开发了一种治理成本方法来解释这些发现。更严格的标准和执行系统导致生产成本的增加。这些成本转移到市场的程度是有限的。因此,核证制度有减少这些费用以增加其市场份额的动机。结果证实,自愿治理方案的能力受到系统限制。

The results confirm that the capacity of voluntary governance schemes is systematically restricted.","PeriodicalId":296234,"journal":{"name":"SRPN: Sustainable Development (Topic)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122799162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We review the emerging literature on climate and conflict. We consider multiple types of human conflict, including both interpersonal conflict, such as assault and murder, and intergroup conflict, including riots and civil war. We discuss key methodological issues in estimating causal relationships and largely focus on natural experiments that exploit variation in climate over time. Using a hierarchical meta-analysis that allows us to both estimate the mean effect and quantify the degree of variability across 55 studies, we find that deviations from moderate temperatures and precipitation patterns systematically increase conflict risk. Contemporaneous temperature has the largest average impact, with each 1σ increase in temperature increasing interpersonal conflict by 2.4% and intergroup conflict by 11.3%. We conclude by highlighting research priorities, including a better understanding of the mechanisms linking climate to conflict, societies’ ability to adapt to climatic changes, and the likely impacts of future global warming.
我们回顾了关于气候和冲突的新兴文献。我们考虑了多种类型的人类冲突,既包括人际冲突,如袭击和谋杀,也包括群体间冲突,包括骚乱和内战。我们讨论了估计因果关系的关键方法问题,并主要关注利用气候随时间变化的自然实验。通过分层元分析,我们既可以估计平均效应,又可以量化55项研究的变异性程度,我们发现,偏离中等温度和降水模式会系统性地增加冲突风险。同期气温的平均影响最大,气温每升高1σ,人际冲突增加2.4%,群体间冲突增加11.3%。最后,我们强调了研究重点,包括更好地理解气候与冲突的联系机制、社会适应气候变化的能力以及未来全球变暖的可能影响。

Emerging Legislative Regimes for Regulating Carbon Capture and Storage Activities in Australia: To What Extent Do They Facilitate Access to Procedural Justice? 澳大利亚监管碳捕获和封存活动的新立法制度:它们在多大程度上促进了程序正义的获得?

Anthropogenic climate change is a fundamental challenge. Of the various responses to this “super wicked problem”, carbon capture and storage (CCS) is one that has been mooted in Australia during recent years. While many commentators continue to question the technological and economic feasibility of CCS, a number of Australian governments have adopted a proactive stance to CCS by amending or enacting legislation to regulate CCS activities in their respective jurisdictions. To date, there has been little critical examination of these legislative regimes and their implications for the future role of CCS in Australia. Accordingly, this article will focus upon one central area of CCS regulation that has not been comprehensively addressed by the existing literature – that is, the extent to which emerging legislative regimes for regulating CCS activities in Australia facilitate access to procedural justice. Access to procedural justice will generally be facilitated in circumstances where the law gives procedural rights to members of the community of justice to: have access to information, participate in decision-making processes, and have access to review procedures before a court or tribunal to challenge decision-making or impairment of substantive or procedural rights. This article undertakes a comparative analysis of the laws that have been enacted or amended to regulate CCS activities in Australian jurisdictions in order to identify standards of best practice for facilitating access to procedural justice. It finds that while many of the laws regulating CCS activities in Australia reflect clear attempts by government to facilitate access to procedural justice, some of these laws fall short of facilitating access to procedural justice in an adequate or sufficient manner. Recommendations for law reform are made with the aim of providing guidance as to how Australian CCS laws can better facilitate access to procedural justice in the future.
人为造成的气候变化是一个根本性的挑战。在针对这个“超级邪恶的问题”的各种回应中,碳捕获和储存(CCS)是近年来在澳大利亚讨论的一个。虽然许多评论家继续质疑CCS的技术和经济可行性,但一些澳大利亚政府已经采取了积极的立场,通过修改或颁布立法来规范各自管辖范围内的CCS活动。迄今为止,对这些立法制度及其对澳大利亚CCS未来作用的影响的批判性审查很少。因此,本文将重点关注CCS监管的一个核心领域,该领域尚未得到现有文献的全面解决,即澳大利亚监管CCS活动的新兴立法制度在多大程度上促进了程序正义的实现。在法律赋予司法界成员程序性权利的情况下,诉诸程序正义通常会得到便利,这些权利包括:获得信息、参与决策过程、在法院或法庭对决策或实质性或程序性权利的损害提出质疑时,可以利用审查程序。本文对澳大利亚司法管辖区为规范CCS活动而颁布或修订的法律进行了比较分析,以确定促进诉诸程序正义的最佳实践标准。报告发现,虽然澳大利亚许多规范CCS活动的法律都明确反映了政府为促进诉诸程序正义所作的努力,但其中一些法律未能以充分或充分的方式促进诉诸程序正义。提出法律改革建议的目的是为澳大利亚CCS法今后如何更好地促进诉诸程序正义提供指导。
