Landscape ecology and conservation management—Evaluation of alternatives in a highway EIA process

The use of an Integrated Landscape Ecological Approach on the evaluation of the impact of a proposed highway over a high sensitive habitat of the highly endangered Iberian Lynx (Lynx pardina L) is described. This method prevents the occurrence of common errors in the decision making process by allowing an increased knowledge of the ecological constraints of the project. It builds, consequently, a very powerful tool for nature conservation assessment and for the ecological evaluation and the decision process in situations of low ecological data availability. The conflict of arguments on the consistency of the conclusions of the method is also described.

氯消毒再生水中4种卤乙酸的测定和影响因素分析

再生水在回用过程中氯消毒副产物对人体产生的危害逐渐引起人们的关注.在USEPA552.3(2003)标准方法的基础上,建立了适用于检测再生水中氯消毒副产物4种卤乙酸(haloacetic acids,HAAs)的分析方法,并对加氯量、UV254、氨氮浓度等影响因素及控制方法进行了研究.研究表明,方法前处理过程简单、安全,内标、HAAs组分峰在谱图分辨良好;4种HAAs在浓度范围1～150 μg/L内呈线性关系,校准曲线相关系数均大于0.999;加标回收率在82.27％～119.9％之间,满足标准方法的要求;HAAs浓度随加氯量的增大而增大,随氨氮浓度的增大而减小,随UV254的变化不明显;先加氨后加氯的消毒方式产生的HAAs浓度最低,两点加氯产生的HAAs总量要少于单一点加氯.

中国农业非点源污染控制的经济措施探讨--以北京密云水库为例

针对我国农业非点源污染特征,提出污染控制经济政策体系,包括基于限制和约束功能的税费政策,基于引导和鼓励功能的补贴、补偿等优惠政策,以及创建基于流域的使污染削减总成本最小化的排污权交易市场。选择北京市重要水源地———密云水库的2大汇水流域之一的潮河流域(密云县境内)为政策设计示范区,从经济、技术及制度方面分析了各经济政策的功能和适用情况,提出本区以鼓励扶持引导为主、收费惩罚为辅控制削减农业非点源污染的经济政策构想,并估算了对农民环保行为给予补贴和补偿的额度。     

不同再生水处理工艺出水水质回用途径适应性分析

为分析典型再生水处理工艺出水的回用途径适应性,采用标准指数法评价了4座不同处理工艺的再生水厂出水质量,为再生水处理工艺选择和安全回用提供参考。结果表明,4种再生水处理工艺出水用于市政杂用水时基本是安全的;除反渗透(RO)工艺外,其他工艺出水回用于景观环境用水时都存在氮磷指标超标问题;膜处理工艺的出水可以满足工业用水标准,但是常规絮凝过滤工艺出水用作工业用水应注意氮磷等指标的进一步处理;各种再生水处理工艺出水质量均不能满足地下水回灌用水标准,主要是氨氮和环境激素DBP超标问题,用作地下水回灌用水时存在一定的环境风险。     

The literature landscape on peace–sustainability nexus: A scientometric analysis

Academics, policymakers, and practitioners have long considered peace and sustainability to be fundamentally linked. However, despite the increased attention paid toward the intersection of peace and sustainability, there is still limited knowledge on the nature of their linkages. To advance the current understanding on the peace–sustainability nexus and inform an integrated research agenda, this paper employs a scientometric analysis of literature to identify publication trends, thematic clusters, and knowledge gaps. Analyzing the publications according to the types of peace, the pillars of positive peace, the dimensions of sustainability, and the SDGs further reveals weak engagement among academic disciplines and across the SDGs. The results of this analysis emphasize the need for future research to focus on underexamined subjects, geographic regions, and sectors to bolster the linkages between peace and sustainability.Electronic supplementary materialThe online version of this article (10.1007/s13280-020-01388-8) contains supplementary material, which is available to authorized users.     

Personality predictors of speeding: Anger-Aggression and Impulsive-Sensation Seeking. A systematic review and meta-analysis

Introduction: The purpose of this review was to identify the most influential personality predictors of speeding. Method: Thus, this study analyzed the associations of Anger-Aggression and Impulsive-Sensation Seeking with Speeding. Research studies included in online databases and papers identified in previous reviews were considered for inclusion. Results: Using a random effects model, we found a small but significant effect for the relation between Anger-Aggression and Speeding (r = 0.12 [0.06–0.18], Z = 3.85, p < 0.001). We identified a significantly stronger effect for the relation between Impulsive-Sensation Seeking and Speeding, but still of low magnitude (r = 0.23 [0.16–0.29], Z = 6.54, p < 0.001). Moderator analysis revealed only one significant moderator: driver type. Namely, for professional drivers, the relation with Speeding was non-significant for both predictors (r = −0.004, p = 0.958 for Impulsive-Sensation Seeking and r = 0.02, p = 0.720 for Anger-Aggression, respectively) and significantly smaller than the associations for general population and young drivers. Conclusions: Overall, our results confirm Speeding’s associations with both hypothesized most important predictors, but at a low magnitude.     

Examining the impacts of disaster resettlement from a livelihood perspective: a case study of Qinling Mountains,China

Disaster resettlement, as a mitigation and preparedness measure, entails significant economic, physical, and social impacts, which continue to challenge understanding of recovery from major events, especially regarding the extent of the context and environmental efforts to rebuild livelihoods. Based on a case study of Qinling Mountains, China, this research investigates the effects of disaster resettlement from a livelihoods perspective. Methodologically, it proposes a framework that combines the pressure–state–response framework and the sustainable livelihoods approach, and it employs a structural equation model to examine how specific factors affect disaster resettlement. The results indicate that conflicts may occur during and after resettlement owing to the difference or disparity between the concerns of resettled peasants and those of the government. Consequently, the risks related to livelihoods need to be taken seriously. Effective risk communication is critical to bridge the gap between different stakeholders. The paper concludes with some practical and policy recommendations.     

Biodiversity conservation: From ecosystem to the ecosystem approach

The possibility of implementing 12 principles of the ecosystem approach is considered with regard to the results of meetings of the Conference of the Parties to the Convention on Biological Diversity (CBD) and recent international forums. The importance of these principles for achieving the main goals of the CBD is shown, and the role of biosphere reserves in solving urgent problems of biodiversity conservation and sustainable development in adjoining territories of subjects of the Russian Federation is discussed.
