A radical public administration? Green radicalism and policy influence among local environmental officials in Sweden

Green radicalism among local environmental officials in Sweden is examined with the aims of theoretically elaborating on different dimensions of Green radicalism in the context of public administration, exploring the dimensionality of Green radicalism among officials, and examining the extent to which Green radicalism is associated with policy influence. Three types of Green radicalism are identified: Green ethics, Green institutional change, and Green activism. Survey data (N = 701) show that the three theoretical dimensions are present among officials, and that there is no negative association between radicalism and influence. It is primarily officials with Green activism beliefs who perceive themselves as able to influence policy. These findings suggest a need for more nuanced understanding of and further studies into the role of public administration in the quest for more radical Green reforms.     

Hannah Arendt’s turn to the self and environmental responses to climate change paralysis

Environmentalists have struggled with how to mobilize people to act in the face of widespread and now inevitable consequences of climate change. Significant responses to this challenge, such as incentivizing individual Green choices in the market and avoiding the rhetoric of catastrophe, continue the philosophical and political trends, identified by Hannah Arendt, that contribute to world alienation and the decline of politics. Environmental thinkers are invited to use Arendt’s theories of the turn to the self and political action to think critically about contemporary strategies to address climate change.     

Ecological citizenship and democracy: Communitarian versus agonistic perspectives

Grassroots environmental movements have recently started to question the focus on sustainable consumption as a main strategy to tackle climate change. They prefer to address individuals as citizens rather than as consumers, and focus on collective rather than individual change. Two prominent movements in this regard are Transition Towns and Climate Justice Action. While both movements criticise conventional approaches, they put forward entirely different strategies for what has to happen instead. Based on extensive qualitative research, this article analyses how these movements manifest themselves in Flanders (Belgium). The focus is on their different accounts of how and why collective practices have to be built, and the place they attribute to ‘the political’ in this. The analysis reveals the existence of two different forms of ecological citizenship: one communitarian, the other agonistic.     

The promissory note: COP 21 and the Paris Climate Agreement

The 2015 UN climate negotiations in Paris resulted in an inclusive, binding treaty that succeeds the Kyoto Protocol. In contrast to the failure at Copenhagen in 2009, the Paris negotiations are therefore seen as a major diplomatic success that has regenerated faith in the United Nations Framework Convention on Climate Change as a forum for dynamic multilateralism. The Paris Agreement provides a robust framework for ratcheting up efforts to combat global warming. However, the Agreement’s value will remain unclear for some time. The historical path to the Paris accord is outlined, and a preliminary assessment is offered of its key elements and outcomes.     

后巴黎时代气候变化公约资金机制的构建

气候变化公约资金机制是串联全球开展应对气候变化行动的纽带,也是通过国际合作实现"2℃"乃至"1.5℃"温控目标的关键支撑。多年来,由于发达国家和发展中国家在是否依据历史责任划分履约义务上存在根本分歧,公约资金机制面临多渠道并行、运行规则多样化、资金使用分散、运行效率偏低、绩效评估欠缺等问题。本文对气候变化公约缔结20余年来各资金机制的产生和运行进行了系统梳理;对其存在的不足以及在全球气候融资体系中面临的挑战进行了剖析;并基于《巴黎协定》资金案文描述和履约要求,围绕气候资金从筹集到最终绩效产出全过程,就如何构建未来气候变化公约资金机制进行了统筹规划和设计。在机制建设层面,通过出资分摊机制以及公约下集中式管理平台的构建,确保气候资金的充足性、可预见性以及对公约的责任性;在运行操作层面,通过各渠道重点业务领域及国别资金分配体系的优化,推动气候资金的公平性和有效性;在资金使用层面,通过受援国气候资金统一管理实体和监督评估体系的建立,提高气候资金的国家主导性和环境效益。未来,公约资金机制仍将是全球开展应对气候变化国际合作的主要渠道,在《巴黎协定》达成、绿色气候基金正式运行、国际气候制度重新构建的背景下,利用资金机制推动发达国家履行公约义务,切实向发展中国家提供资金、技术和能力建设支持,对确保公约各要素的全面性和平衡性,推动全球应对气候变化行动开展,强化发展中国家集团统一立场都有着重要的现实意义。     

基于安徽省土地利用变化的地形梯度效应分析

为揭示地形因素与土地利用空间格局演变的关系,以安徽省2000年、2005年以及2010年Landsat TM影像和DEM数据为数据源,利用坡向、地形起伏度、坡度变率和地形位指数多种地形因子,并结合地学信息图谱分析理论从综合角度系统研究土地利用结构时空分异格局在地形梯度上的变化特点及其规律。结果表明:1)研究区主要的土地利用类型是耕地和林地,其次是建设用地和未利用土地,且建设用地面积逐期增加趋势显著。2)2000~2010年研究区不同土地利用类型在不同地形梯度区间的分异规律存在明显差异。低地形梯度范围是耕地、水域和建设用地的优势分布区;中地形梯度范围是草地的集中分布区;林地的优势分布区集中在高地形梯度范围。3)2000~2010年研究区土地利用图谱以稳定型和后期变化型为主,低地形梯度和高地形梯度是稳定型图谱的集中分布区,中低、中高和高地形梯度范围是后期变化型图谱的优势分布区。2000~2005年林地的优势分布区有向较低地形位梯度扩张的趋势,其中,耕地是主要的转入来源。2005~2010年耕地的优势分布区有向较高地形位梯度扩张的趋势,变化模式主要为:"林地–耕地"、"未利用地–耕地"和"草地–耕地"。     

川南山地林分变化对土壤物理性质和抗蚀性的影响

以川南天然林(TRL)及其转变成的毛竹林(MZL)、檫木林(CML)、柳杉林(LSL)、杉木林(SML)和水杉林(SSL)为对象,研究不同林分土壤物理性质和抗蚀性差异,以主成分分析法(ZCFM)和隶属函数法(LSHM)分别计算的土壤抗蚀性综合值Ⅰ(KSX-Ⅰ)和Ⅱ(KSX-Ⅱ)评价林分变化对土壤抗蚀性的影响,探索简便易行的土壤抗蚀性综合评价方法。结果表明,天然林转变为人工林后土壤物理性质和抗蚀性变差,呈现出有机质和0.25 mm水稳性团聚体含量、水稳性团聚体平均重量直径、团聚度、孔隙度及物理稳定性指数降低,而结构体破坏率、不稳定团粒指数、容重、分散率及侵蚀系数增加。各林分土壤KSX-Ⅰ和KSX-Ⅱ均呈现出TRLCMLSSLLSLMZLSML的规律变化。土壤抗蚀性指标间相关性均达到显著(p0.05)水平;土壤KSX-Ⅰ和KSX-Ⅱ之间呈显著相关关系(p0.05),且两者均与各抗蚀性指标间呈显著相关(p0.05)。说明天然林植被变化后会使土壤抗蚀性降低,影响原有植被水土保持功能,应该加强天然林及其生态功能保护;ZCFM和LSHM均可作为计算土壤抗蚀性综合值的有效方法,但考虑到计算过程的难易度,后者更简便易行。结果为土壤抗蚀性综合评价新方法的建立提供了参考。     

湖北郧西县庹家湾剖面粒度组成特征及其环境意义

对湖北省郧西县庹家湾(TJW)剖面的地层序列、年代、磁化率及粒度组成进行研究。结果表明:TJW剖面具有表土(MS)→全新世黄土(L0)→古土壤(S0)→过渡层(Lt)→马兰黄土(L1)→黄土与砂互层(T1-al2)→砾石层(T1-al1)的地层序列;在马兰黄土层上部的黏粒含量、黏粒/粉砂值以及磁化率值明显高于典型马兰黄土,而接近古土壤(S0),其成壤作用明显,属于较典型的弱古土壤层(L1-S1和L1-S2),其年龄在27.3~21.6 ka B.P.之间。此现象反映了在汉江上游地区,晚更新世时期的冰期气候并不是持续稳定的,在27.3~21.6 ka B.P.期间存在相对短暂的温暖湿润阶段,这次气候事件可与黄土高原地区进行良好对比。     

Decline of traditional rice farming constrains the recovery of the endangered Asian crested ibis (Nipponia nippon)

Traditional agriculture benefits a rich diversity of plants and animals. The winter-flooded rice fields in the Qinling Mountains, China, are the last refuge for the endangered Asian crested ibis (Nipponia nippon), and intensive efforts have been made to protect this anthropogenic habitat. Analyses of multi-temporal satellite data indicate that winter-flooded rice fields have been continuously reduced across the current range of crested ibis during the past two decades. The rate of loss of these fields in the core-protected areas has unexpectedly increased to a higher level than that in non-protected areas in the past decade. The best fit (R² = 0.87) numerical response model of the crested ibis population shows that a reduction of winter-flooded rice fields decreases population growth and predicts that the population growth will be constrained by the decline of traditional winter-flooded rice fields in the coming decades. Our findings suggest that the decline of traditional rice farming is likely to continue to pose a threat to the long-term survival and recovery of the crested ibis population in China.

The current state of knowledge of ecosystems and ecosystem services in Russia: A status report

This paper focusses on a conceptual overview of ways to address a comprehensive analysis of ecosystem services (ES) in a country as large and heterogeneous as Russia. As a first step, a methodology for assessing the services for the federal subjects of Russia was chosen, i.e., its constituent provinces and similar entities, in physical terms. Russia harbors a great diversity of natural conditions and ecosystems which are suppliers of ES, and likewise a variety of the socio-economic conditions that shape the demand for these services and their consumption. The methodological approach described permits several important tasks to be addressed: the evaluation of the degree of satisfaction of people’s needs for ES, the identification of ecological donor and acceptor regions, and zoning of the country’s territory for ES assessment. The next step is to prepare a prototype of a National Report on ES in Russia, for which we are presenting the planned structure.
