江苏省工业废水排放及其与环境污染治理投资的耦合关系研究

研究了1990年-2007年江苏省工业废水排放与经济增长的动态关系,结果表明1990年-2007年江苏省工业废水排放量呈现在波动中略有上升的趋势,年均增长率显著低于GDP的增长速度,工业废水并未与经济同步增加;采用库兹涅茨曲线对废水排放量与人均GDP之间的关系进行拟合发现,目前江苏省人均GDP已经超过转折点水平,因此今后一段时期随着经济的发展,废水排放量呈现下降趋势,说明江苏省环境治理取得了一定的效果;同时,研究表明江苏省各县（市、市辖区）工业废水排放大多呈现下降趋势,排放量最高区集中于苏南一带,而环境治理投资全省呈现上升趋势,全省环境治理投资额增长速度较快,以苏北地区最为明显;研究还发现废水排放量与投资额的空间耦合关系日益密切,体现了江苏省对环境治理的力度在逐步加大。

太湖流域不同管理模式的社会经济环境系统演化模拟

基于复杂自适应系统理论构建了社会经济环境系统模型,采用计算实验方法模拟分析了太湖流域在经济优先和水环境保护优先2种管理模式下的动态演化过程,得到了农业与工业经济发展水平、就业状况和水环境改善情况的演化规律.结果表明,在综合考虑社会、经济、水环境的基础上,2种管理模式均能在一定程度上实现经济和就业的增长,同时改善水环境.环境保护优先模式虽能有效保护水环境,却会牺牲部分经济发展和就业保证.不同地区在演化过程中表现出差异性,常州和湖州经济获得较快增长;苏州、上海在就业方面做出较大贡献;无锡和苏州水环境改善效果最为明显.     

废旧轮胎再制造过程的环境污染及防治研究

随着汽车和轮胎行业的迅速发展,由此产生的废旧轮胎也逐年增加。废旧轮胎再利用技术既可解决橡胶资源短缺问题,又能消除黑色污染,是循环经济的重要环节,在推广这一技术的同时,应注意其伴生的环境污染。再利用生产主要分为清洗、打磨、粘中垫胶、粘预硫化胎面、低温硫化等步骤。此过程将产生粉尘、非甲烷总烃废气、橡胶颗粒以及清洗废水等污染物。应对这些污染物采取有效的治理措施,使其满足达标排放和无害化的要求,以达到经济利益和环境保护的双赢。     

The Belt and Road Initiative and the 2030 Agenda for Sustainable Development: seeking linkages for global environmental governance

ABSTRACT

Global environmental cooperation serves as an important part in the Chinese ideal of building a Community with a Shared Future for all Human Beings. The report of 19th CPC National Congress indicates that China is committed to proactive mitigation under the Paris Agreement and further participating in global environmental governance under the 2030 Agenda for Sustainable Development, and both of which are largely integrated to the Belt and Road Initiative (BRI). BRI are also closely linked with South–South environmental and climate cooperation proposed by China from previous UN summits. Based on shared ideas, intersected agendas, and compatible governance approaches, BRI and the 2030 Agenda for Sustainable Development grow increasingly relevant and they might form synergies based on increasingly interactive relations. In sum, seeking and intensifying the linkages between BRI and 2030 sustainable development goals (SDGs) could address global environmental governance deficits and enhance cooperation among nations.     

Using participatory geographic approaches for urban flood risk in Santiago de Chile: Insights from a governance analysis

Studies based on information acquired by participative geographic approaches have sought to cope with emergency situations and disasters such as floods. However, the impact of these approaches to flood risk governance systems in order to understand these types of events as a complete risk cycle is still not clear. This paper focuses on analysing the governance possibilities of using participative geographic information like volunteered and public participatory geographic information for flood risk reduction in the case of Santiago de Chile, a city which regularly experiences urban floods during rainy seasons. Based on in-depth interviews and document analysis, our study indicates that a relevant part of the current information used for flood risk reduction efforts is provided to local and regional authorities by the affected population. Though, local actors are not recognized by central agencies as valid agents for the production of official information. Moreover, there are neither instances of communication or deliberation with the community, which reduces the capacity of local actors to discuss possible solutions. Participative geographic instruments are seen as potential mechanisms to strengthen work relations among local actors and authorities, by enhancing new logics for producing and sharing information. The impacts for the current risk governance system though can be diverse depending on the participants' level of commitment of participants and the political relations between actors and agencies. Considered as merely data acquisition and analysis mechanisms, participative instruments reproduce the existing hierarchical top-down structures. Furthermore, local-based approaches can enhance local work, support local diagnostics and increase the decision capacity of citizens.     

“The commons” as a dynamic variable in understanding strategic alliances of scale: A groundwater case study in Pajaro Valley,California

Groundwater, a critical resource in many parts of the world, is often characterized as a common pool resource (Brozovic et al., 2006). Multiple individuals utilize groundwater from a basin, and each person has the capacity to reduce the quantity or quality available to others. We turn to a case study of the Pajaro Groundwater Basin in Central California to re-envision the characterization of “commons.” While providing a useful frame from which to analyze groundwater depletion in the Pajaro, we find Common Pool Resource (CPR) theory to be imprecise in its approach to a geographic scale. The notion of the “commons” is central to CPR studies, but there is wide divergence in what the “commons” constitutes, both spatially and socially (Laerhoven and Ostrom, 2007). Rather than propose a normative definition for the “commons,” we suggest that the “commons” as a geographic category is socially constructed and dynamically active over time, akin to the analytic of scale as developed within the fields of political ecology and geography. This move from situating the “commons” as a fixed and discrete geographic area to that which is constantly changing and relational helps us to better understand the ways in which water users collaborate and communicate around shared groundwater sources.     

Solution-oriented global environmental assessments: Opportunities and challenges

This article provides an introduction to the Special Issue dedicated to “Solution-oriented Global Environmental Assessments: Opportunities and Challenges”. In the follow-up to the Paris climate agreement and the adoption and early implementation of the global Sustainable Development Goals involving many synergies and trade-offs, the need to shift the focus from environmental problem analysis towards the exploration of specific solution options can be observed in international environmental governance debates. To remain policy-relevant, credible and legitimate, global environmental assessments (GEAs) must carefully adapt to a rapidly evolving governance landscape. This Special Issue sheds light on the potential utility and implications of increased solution-orientation of GEAs. It builds on the research project “The Future of Global Environmental Assessment Making” that was jointly initiated in 2013 by UN Environment and the Mercator Research Institute on Global Commons and Climate Change. The article collection includes research on the coevolution of GEAs and the increasingly solution-oriented governance context; conditions of success for contemporary GEAs; the treatment of divergent viewpoints, stakes and stakeholders in solution-oriented GEAs; knowledge aggregation; and the enhanced measurement of GEA effectiveness in the emerging governance landscape.     

Adaptive governance to typhoon disasters for coastal sustainability: A case study in Guangdong,China

Globally, more people and assets are concentrated on the limited coastal plains where they are exposed to frequent disasters, such as typhoons, rainstorms and floods that often result in tremendous casualties and economic losses. Based on the causal analysis of the historical typhoon cases in the Guangdong Province of China, this study indicates that structural measures alone are not sufficient to resist and offset the impacts caused by typhoon disasters. Additionally, structural measures are unsustainable due to their high investment and low security. Adaptive governance, which uses non-structural measures and resilience building, is a feasible and cost-effective strategy for responding to the cascading effects of typhoon disasters. Multi-stakeholder participation and vertical–horizontal coordination are essential for providing adaptive governance to typhoon disasters. A risk-sharing model was put forward by bringing together the government, insurance companies and victims. Furthermore, a favorable atmosphere for public participation in disaster risk reduction can be fostered and should be a long-term adaptation strategy. The views and frameworks of adaptive governance provide policy makers with insights on coastal disaster risk management within the broader context of climate change.
