Which “fairness”, for whom,and why? An empirical analysis of plural notions of fairness in Fairtrade Carbon Projects,using Q methodology

Fairness is a relative concept with multiple, subjective and competing notions of what it is, how to achieve it, and for which beneficiaries. Fairtrade International's collaborative efforts to develop a standard to certify Fairtrade Carbon Credits (FCCs) brought together multiple stakeholders in a deliberative context. This paper uses Q methodology to empirically assess the notions of fairness this wider consultation group held. Three distinct ‘factors’ (or perspectives) are identified, and discussed in relation to a multi-dimensional framework for exploring fairness. The first factor prioritises development delivered through organisations, participation in decision-making and use of minimum prices to adjust trade imbalances. The second factor conceptualises a non-exclusive approach maximising generation and sales of FCCs, involving a commodity chain where everyone performs their optimum function with financial transparency and information-sharing to facilitate negotiations. The third factor involves minimising intervention, allowing carbon commodity chains and project set-ups to function efficiently, and make their own adjustments to enhance benefits access and quality received by beneficiaries. The three factors reflect debates within carbon and fair trade spheres about who should be playing which roles, who should be accessing which benefits, and how people should be supported to interact on an uneven playing field. Communicating findings to standards organisations enables a more open and inclusive policy process. Our research provides a critical reflection on these plural notions of fairness, identifying areas of (dis)agreement within the FCC dialogue, and provides a wider, yet manageable, set of inputs for supporting the FCC process during its inception and subsequent implementation. Clearer definitions of “fairness” are also useful for standards organisations in reviewing ex post whether “fairness” goals have been met.     

建立内蒙古生态环境恢复补偿机制若干问题探讨

生态环境恢复补偿机制的建立是科学利用生态资源和保持良好生存环境的必然途径,内蒙古自治区是全国天然植被分布面积最广地区之一,天然植被在保持流域、区域生态平衡,防止和减轻自然灾害,确保地区生态安全方面的重要作用毋庸置疑,然而由于原因,长期困绕我区的生态环境问题,如:森林生态系统的水源涵养、土壤保持、生物多样性保护功能衰退,水土流失的加剧、沙地活化;草场退化等级愈来愈高;湿地面积缩小,河道断流问题依然存在。近年随着矿业经济的兴起,又出现了矿山用水与农业生产争水、污染地下水等问题。因此,继矿产资源开发热潮之后,迅速做出制度安排尤为重要,本文通过对生态恢复补偿机制建立背景、重点、难点若干的探讨,旨在提出一些结合实际的可操作的补偿措施建议和意见,为制定内蒙古生态恢复补偿管理办法提供参考、并为该领域制度的完善提出技术层面的支持。

Toward sustainable livelihoods after war: Reconstituting rural land tenure systems

Land tenure plays a primary role in sustainable development efforts. However armed conflict and its repercussions reconfigure the network of social relations upon which all land tenure systems depend. In post‐conflict settings new laws have the opportunity to address tenure issues in the context of what people are already doing ‘on the ground’, with a view to moving from the fluidity of post‐conflict situations to a more solidified and peaceful social and legal environment. However there exists a lack of tools to analyze postwar land tenure and the prospects for reconstituting tenure systems to support recovery and development. This paper uses the Sustainable Livelihoods framework to examine postwar land tenure issues in order to draw out latent opportunities within emergent informal smallholder tenure constructs which may have utility in the reconstitution of national tenure systems.     

Climate change and transdisciplinary science: Problematizing the integration imperative

In this article we critically examine the ‘integration imperative’ in transdisciplinary environmental science and build on social constructivist and political theories to suggest alternative approaches of knowledge co-production in transdisciplinary settings. Our argument builds upon a body of literature in social studies of science to cull insights about knowledge co-production, social learning, and the ecology of team science, particularly as it relates to climate change adaptation. Couched in this transdisciplinary literature, we demonstrate, is the assumption that integration necessarily can and should be a regulative ideal. We critique this assumption by examining the ‘messy’ politics of achieving consensus among radically different, and sometimes irreconcilable, ways of knowing. We argue that the integration imperative conceals the friction, antagonism, and power inherent in knowledge co-production, which in turn can exclude innovative and experimental ways of understanding and adapting to climate change. By way of conclusion, the final section explores three alternative models of knowledge co-production – triangulation, the multiple evidence-based approach, and scenario building – and illustrates their application in the context of transdisciplinary research in climate change adaptation in the arctic, focusing on alternative means of cross-boundary engagement with indigenous ways of knowing.     

OBIA与RF结合的龙口市土地利用信息提取方法

为提高中分辨率遥感影像解译精度,本文提出面向对象影像分析（Object Based Image Analysis,OBIA）与随机森林（Random Forest,RF）结合的土地利用信息提取方法。采用Landsat 8 OLI影像,针对不同地物特点,阈值分割和多尺度分割结合创建影像对象,规则集和分类器协同分类,基于Relief F算法分别对光谱特征、纹理特征及所有特征降维筛选特征子集,并与全部特征一起应用RF建模,对龙口市进行土地利用信息提取与比较。结果表明：OBIA与RF结合提取土地利用信息,基于Relief F算法筛选纹理特征,保留完整光谱、几何、空间关系特征构建RF模型,建模错分率为0.0958,分类总体精度和Kappa系数分别为89.37%和0.872,取得较理想结果。该方法可应用于中分辨率遥感影像土地利用信息提取。

2021年夏季新乡市城区臭氧超标日污染特征及敏感性

基于2021年6～8月新乡市市委党校站点观测的挥发性有机物(VOCs)、常规空气污染物和气象参数,采用基于观测的模型(OBM)对臭氧(O₃)超标日的O₃敏感性和前体物的管控策略进行了研究.结果发现,O₃超标日呈现高温、低湿和低压的气象特征.在臭氧超标日,O₃及其前体物的浓度均有上升.臭氧超标日的VOCs最高浓度组分为含氧挥发性有机物(OVOCs)和烷烃,臭氧生成潜势(OFP)和·OH反应性最大的VOCs组分为OVOCs.通过相对增量反应性(RIR)分析,新乡6月O₃超标日臭氧生成处于VOCs控制区,7月和8月处于VOCs和氮氧化物(NO_x)协同控制区,臭氧生成对烯烃和OVOCs最为敏感.6月各前体物的RIR值在一天中会发生变化,但始终保持为VOCs控制区;7月和8月在上午为VOCs控制区,中午为协同控制区,下午分别为协同控制区和NO_x控制区.通过模拟不同前体物削减情景,结果表明削减VOCs始终有利于管控臭氧,而削减NO_x     

河流CO2与CH4排放研究进展

河流作为连接海-陆两大碳库的主要通道,其水-气界面二氧化碳(CO_2)与甲烷(CH_4)排放构成全球碳循环的重要环节,对全球气候变暖的贡献不容小觑.明确河流水体CO_2与CH_4产排过程、时空特征以及控制因素是认识河流生态学功能以及其对变化环境响应的重要内容.基于当前河流CO_2与CH_4排放研究进展,构建河流碳排放动力学概念框架(内源代谢、陆源输入),并从全球尺度、区域尺度、流域尺度综述了河流碳排放时空变异性特征以及存在的研究不足.在理解碳排放动力学概念框架和时空变异特征的基础上,构建了河流CO_2与CH_4动力学控制因子分层框架(内部因子:有机质、温度、营养盐;外部因子:水文、地貌、人类活动),深入探讨了河流碳排放的关键影响因素.最后,根据当前研究中存在的不足,提出河流碳排放应将纳入区域陆地碳平衡过程,今后研究重点应包括流域尺度上河流CO_2与CH_4内源产生与陆源输入相对贡献的量化研究、不同界面CO_2与CH_4产生与排放过程研究、高时空分辨率的监测数据的补充以及变化环境与人类活动干扰下河流碳排放的响应过程等,为理解河流生态学过程及生态系统功能提供基础,同时为我国进一步深入开展相关研究提供借鉴.
