中国循环经济发展规划的进展探讨

当前循环经济的研究工作在中国深入展开,与此相适应的循环经济规划的编制和实施工作紧密进行。文章围绕规划的理论基础、现实意义,以及基本元素构成进行介绍。就开展规划编制工作的现状展开综述,归纳所取得的成绩与存在的缺陷、待解决或完善的内容。从我国实际并行的若干规划出发．初步阐释其与循环经济规划协调的原理。现阶段的循环经济探索主要还是基于环境。其可能的经济属性的严重探完不足。试行循环经济规划之后增加的再生成本等其他相关问题在后一阶段的规划推进中需深入考虑。

Linking corporate climate adaptation strategies with resilience thinking

Within modern society, business organizations have a co-evolutionary relationship with society and ecosystems. Business organizations face highly diverse risks which they have to recognize, reflect on and handle. Climate change and its impacts clarify the need for managing overall system risk. Research has shown that climate vulnerability of business organizations in the German food industry is characterized by impacts that, in particular, affect business organizations indirectly. Indirect climate change caused impacts are complex, uncertain and characterized by a high degree of unpredictability. They focus on the derived social, ecological, economic and cultural consequences of the direct physical impacts from a worldwide perspective. This paper shows that introducing resilience thinking helps to identify strategic risks and opportunities coping with climate change caused impacts in sense of corporate climate adaptation strategies. Furthermore, it is shown from a strategic management perspective that mitigation is a profound element of long term adaptation strategies.     

A conceptual framework for analyzing sustainability strategies in industrial supply networks from an innovation perspective

This article proposes a new conceptual framework concerning the implementation of sustainability in supply networks from an innovation perspective. Based upon a recent qualitative literature review in environmental, social/ethical and logistics/operations management journals, this article summarizes and analyses the approaches found. Concluded is that even though innovation, socialization, experimental learning and cultural perspectives have been acknowledged as being relevant to explaining supply network dynamics in general, they are rarely included in the current frameworks concerning sustainability. The question still remains why companies influenced by the same external factors and similar in size and power develop a different strategy towards sustainability aspects in their supply network. The article demonstrates with the first results of a survey held in the fashion/clothing sector the relevance of this question.The proposed conceptual framework states that the capability to develop a strategy is influenced by the innovation power of the “focal” company and its supply network. The three implementation strategies presented in the framework are: resign, offensive and defensive. Two propositions are defined to be tested. These propositions focus on the relation between the level of innovation power and the implementation strategy concerning sustainability. Factors used to characterize the innovation power of the “focal” company are: external orientation and transparency, cooperation between departments, learning and adapting, leadership, autonomy and possibility for experimenting, and result driven. Cooperation in the supply networks is characterized by factors like trust, reputation, joint programmes, and cooperative information systems throughout the supply network.In empirical research, strategies found will be related with the level of innovation power. This level will be measured using the factors mentioned. The results might add a new innovation dimension to an improved conceptual framework within the interdisciplinary field of sustainability and supply network research.     

基于行政层级构建“橄榄型”生态文明建设指标框架

当前生态文明指标体系研究和实践中,一方面生态文明指标体系和生态文明指数构建方法不尽相同,另一方面刻意追求统一的指标体系而忽视了不同行政层级间的差异性,对层级间指标衔接等问题缺乏考虑。依照生态文明内涵以及十八大尤其是十八届三中全会关于生态文明建设尤其是生态文明考核指标要求,提出各行政层级构建“橄榄型”生态文明建设指标框架体系。该指标体系强调国家的顶层宏观引导作用,并以市县级生态文明建设指标体系为基础,向上构建省级生态文明建设指标体系,向下构建乡镇级生态文明建设指标体系,体现“国家—省—市县—乡镇”之间的整体性、衔接性、协调性,真正反映生态文明建设是“自上而下引导力”和“自下而上推动力”的合力作用的结果,服务于我国生态文明建设的持续开展和长效管理。     

Resilience assessment of chemical industrial areas during Natech-related cascading multi-hazards

In chemical industrial areas, technological accidents triggered by natural events (Natech events) may escalate. Complex cascading multi-hazard scenarios with high uncertainties may be caused. Resilience is an essential property of a system to withstand and recover from disruptive events. The present study focuses on the change of the resilience level due to (possible) interactions between cascading hazards, chemical installations and safety barriers during the dynamic evolution of fire escalations triggered by a natural hazard (certain cascading multi-hazard scenarios). A quantitative resilience assessment method is developed to this end. The state transition of a system facing accidents in the context of resilience is explored. Moreover, the uncertainties accompanying an accident evolution are quantified using a Dynamic Bayesian Network, allowing a detailed analysis of the system performance in different time steps. System resilience is measured as a time-dependent function with respect to the change of system performance. The applicability of the proposed methodology is demonstrated by a case study, and the effects of different configurations of safety barriers on improving resilience are discussed. The results are valuable to support disaster prevention within chemical industrial areas.

An integrated river basin-coast-sea modelling scenario for nitrogen management in coastal waters

Linked river basin and coastal water models were applied to analyse the effects of an optimal nitrogen management scenario in the Oder/Odra river basin on water quality in the Oder (Szczecin) Lagoon and the Pomeranian Bay (Baltic Sea). This scenario would reduce nitrogen loads into the coastal waters by about 35%, a level which is similar to the load of the late 1960’s. During summer the primary production and algae biomass in the Oder estuary is limited by nitrogen, which makes a nitrogen management reasonable. The comparison of the late 1960’s and the mid 1990’s shows that an optimal nitrogen management has positive effects on coastal water quality and algae biomass. However, this realistic nitrogen reduction scenario would not ensure a good coastal water quality according to the European Water Framework Directive. A good water quality in the river will not be sufficient to ensure a good water quality in the lagoon. Nitrogen load reductions bear the risk of increased potentially toxic, blue-green algae blooms, especially in the Baltic coastal sea. However, to reach water quality improvements in lagoons and inner coastal waters, nitrogen cuts are necessary. A mere focus on phosphorus is not sufficient.     

Illegal landfill in Italy (EU)—a multidisciplinary approach

Illegal dumping of solid waste is a matter of recent concern because of its numerous impacts. The regulatory framework of the European Union and Italy is disclosed. Degradation of air, bodies of water, groundwater, and soil can occur in the illegal landfill and surrounding sites causing e.g. acidification, eutrophication global warming and photochemical smog. Animals and plants are subjected to landfill borne pollutants that can damage them seriously. Landfill pollutants have also harmful effects on human beings raising the risk of illness such as cancer and cardiorespiratory disease. Finally illegal landfilling practices lead to economical, aesthetic impacts, and sociological discomfort that lead to multiple collective actions, blockages, and information campaigns, rising sense of belonging.
