Toward an environmental justice of the rural-urban interface

In this article, I make the case for an explicit extension of environmental justice research to the rural-urban interface or fringe. A more systematic exploration and synthesis of the blurred boundaries and transitional character of the interface might advance the empirical scope of environmental justice research while contributing to the environmental justice literature’s evolving treatment of space, ecology, and oppression. I subsequently synthesize previous research to outline some fringe characteristics, which signal the interface as a distinct geographical space deserving of closer attention in environmental justice studies, before proposing a few unique dimensions of injustice on the interface. In light of these new facets of rural-urban injustice, I finally outline some preliminary empirical and conceptual questions the interface might pose to environmental justice studies more broadly.     

Assessing environmental justice through potential exposure to air pollution: A socio-spatial analysis in Madrid and Barcelona,Spain

The concept of environmental justice (EJ) has recently gained currency, both as a factor for and a goal of sustainable development. Its implementation in practice implies establishing current environmental injustice patterns and analysing planning policies, with the aim to reduce socio-demographic inequalities in the negative environmental impact borne by different population groups. This paper proposes a method to assess differential exposure to excessive pollution levels by socio-demographic groups in intra-urban spaces.The approach developed in this paper is based upon GIS and quantitative spatial analysis techniques. It incorporates the idea of an ‘environmental justice weighting scale’ for policy-making, using normative pollution thresholds to measure inequalities more objectively and consistently. Spain’s two largest cities, Madrid and Barcelona, have been chosen as case-studies, taking nitrogen dioxide as the pollutant, and the geographic distribution of six vulnerable population groups (children, elderly people and international immigrants) in the year 2010. The results reveal that a large part of these groups suffer exposure to air pollution exceeding the maximum permitted levels disproportionately, which would imply a case of environmental injustice.     

Green growth rhetoric versus reality: Insights from Indonesia

By 2030 Indonesia aims to reduce its CO₂ emissions by 29% while maintaining a 7% annual GDP growth rate, thus making “green economy” a reality. Based on a review of literature and secondary data and interviews with key informants, this article examines the gap between these national ambitions and the reality on the ground, with particular attention to the challenges of multi-scalar environmental governance. It first introduces the green economy concept and discusses the main green growth policies and initiatives at the national level. The article then examines green growth ambitions at the provincial level in East Kalimantan province. Our findings suggest that existing plans to further expand oil palm plantations are at odds with provincial efforts to reduce emissions. This highlights a key paradox we identify at the heart of the green economy concept as it is developing in Indonesia: between a development trajectory based on resource extraction and agro-industrial development, and ‘green’ aspirations linked to environmental protection and greenhouse gas emissions reductions. We conclude that the main challenges to address these contradictions are related to the lack of coordination between different governance scales and a political economy that is not conducive to reforms in the land-based sector. There is a need to align investment, planning, and green growth policies, based on a strong political commitment and an awareness of social and environmental trade-offs. On a more general level the article shows that the green economy concept refers to a form of environmental governance in which authorities and interests may overlap and come into conflict at different scales. Hence, differing priorities may lead the material expression of the green economy to diverge significantly from policy as it is initially laid out.     

Adaptive environmental governance of changing social-ecological systems: Empirical insights from the Okavango Delta,Botswana

Adaptive management and related fields have theorized new governance strategies that embrace complexity and are able to respond effectively to changing and unpredictable biophysical dynamics. However, this body of work pays inadequate attention to important on-the-ground realities, including feasibility of implementation and the power dynamics embedded in multi-scalar systems of environmental governance. This paper presents findings from a research project on challenges to adaptive management in the variable wetland ecosystem of the Okavango Delta, Botswana. Many residents of this rural region rely on transitional agricultural practices, shifting between dryland and floodplain farming in response to dynamic precipitation and flooding patterns. Higher than average floods in 2009–2011 inundated many floodplain fields past the point of production, causing farmers to shift to the dryland for multiplem seasons. At the same time, the highly centralized Government of Botswana began to implement stricter regulations over floodplain resources, which stemmed in part from a new adaptive management plan developed for the region. As a result, many farmers felt pressured by the government to abandon transitional livelihood practices and to shift permanently to dryland agriculture even though many preferred to continue floodplain farming. This loss of a responsive livelihood strategy will likely result in decreased long-term adaptive capacity for many residents. Drawing on these findings, this paper advances the argument that if adaptive management is to become a viable option for communities in changing environments, more attention must be given to the role of unequal power relations in multi-scalar systems of environmental governance.     

Public environmental concern in China: Determinants and variations

How much are Chinese people and various citizen groups concerned about the environment relative to other major public problems? What are the key factors and to what extent do these factors shape individual Chinese environmental concern? Based on a micro-macro model and a county fixed model proposed in this study, we employ nationwide representative public opinion survey data and provincial statistics to examine the determinants and variations of public environmental concern in China. The data shows that environmental concern is not among the top-ranked issue concerns in China overall, but in the urban areas and in the east-coastal region environmental protection features as a rather important issue. Our regression analyses further demonstrate that the Chinese environmental concern is significantly affected by both micro-level socio-demographic variables and macro-level regional economic conditions and environmental risks. In the east-coastal region, such individuals as urbanites with high income are most environmentally concerned. There is a lack of concern over environmental issues among the public in the west region, where little association between individual sociodemographics and their environmental concern is detected. In the central-northeast region, education effect is evident in the rural area. Location contextual factors such as economic development and environmental risk account for most of the observed variations in public environment concern.     

新《环境保护法》下湿地保护的立法思考——基于江苏省湿地保护立法现状的分析

江苏省湿地资源丰富,湿地种类多样,分布广泛,但面临着严重的污染和破坏,且湿地立法相对分散,没有形成完整的湿地保护法律体系。《环境保护法》的修订,特别是生态红线、按日计罚、生态补偿、公益诉讼等制度设计,为江苏省湿地保护立法提供了强有力的制度支撑。在此情形下,制定"江苏省湿地保护条例"显得十分必要。     

Guinea pig or pioneer: Translating global environmental objectives through to local actions in Central Kalimantan,Indonesia’s REDD+ pilot province

Many difficulties have arisen from top-down approaches to the design and implementation of global environmental initiatives. The concept of translation and other analytical features of Actor-Network Theory (ANT) can offer a way of conceptualising these difficulties and their practical effects. By translation, we refer to what happens in-between the formulation of international goals and the results of implementation, and more specifically, relations and negotiations within this broader process. We examine several aspects of translation in the case of Reducing Emissions from Deforestation and Forest Degradation (REDD+), a prominent global environmental initiative. Using an ethnographic approach, we explore local responses in Central Kalimantan province, Indonesia, to REDD+ ideas and goals that originate at international and national levels. Following selection in 2010 as the official REDD+ pilot province, Central Kalimantan became a site for the convergence of actors and projects with varied sources of funding. The study identifies a central tension that emerged between an initial vision of Central Kalimantan as a pioneer, and local concerns about being used as an experimental subject or ‘guinea pig’ for the testing of externally designed schemes. Results show that greater flexibility in the design of programs and initiatives is needed, to provide space for local inputs. Implementation should pay attention to how local actors are included in planning processes that inform decision-making at higher jurisdictional levels. To bring about intended changes in land use, programs like REDD+ need to extend beyond a focus on short-term projects and targets, to instead emphasise long-term investments and forms of collective action that support learning.     

Closing the governance gaps in the water-energy-food nexus: Insights from integrative governance

The water-energy-food nexus has become a popular concept in environmental change research and policy debates. Proponents suggest that a nexus approach promotes policy coherence through identifying optimal policy mixes and governance arrangements across the water, energy and food sectors. Although the nexus literature identifies some barriers to achieving coherence it does not clearly explain why the barriers are present, what influences them, and how they can be acted upon. These gaps disconnect the nexus literature from the governance processes it ultimately seeks to influence. This paper examines how the integrative environmental governance literature can help to close these gaps. It extracts insights from seven streams of research literature and discusses their relevance for the nexus literature. We argue that connecting the nexus to decision-making processes requires: i) rethinking the boundaries of nexus analysis vis-à-vis other sectors and levels; ii) elaboration of shared principles that can guide decision-making towards policy coherence − or an appropriate form of fragmentation − in different contexts; iii) viewing policy coherence as a continuous process of changing values and perception rather than as an outcome.     

基于A-Train卫星编队资料的热带气旋强度估算

准确估算热带气旋(TC)强度,对于预测TC发展、减少财产损失具有重要的意义。前人将TC看作满足静力平衡和梯度风平衡的轴对称涡旋系统,基于云顶高度、云顶温度、海表面气压等物理量建立了TC强度估算模型,该模型未考虑环境垂直风切变对TC强度的影响。本文提出一种修正模型,通过统计拟合手段将垂直风切变加入原模型中。从2006—2015年的Cloud Sat资料中筛选出穿心个例共63个。针对云雷达(CPR)数据特点,提出根据反射率因子的垂直分布确定眼墙和外围边界位置的方法。分别用原模型与修正模型对这63个TC个例进行强度估算。与最佳路径数据相比,原模型结果总体偏大,尤其对风切变较大、强度较小的个例估算效果不佳。修正模型对于风切变大于5 m·s~(-1)的个例误差明显减小,平均绝对误差MAE、均方根误差RMSE和平均绝对误差百分比MAPE分别从5.8 m·s~(-1)、7.7 m·s~(-1)和19.5%变为3.5 m·s~(-1)、4.9 m·s~(-1)和11.5%。在一定强度范围内,修正模型估算效果随着强度的增强而提升。修正模型对于成熟阶段的个例效果更好,北半球的估算精度高于南半球,纬度越高,估算误差越小。试验结果表明,用该修正模型估算TC强度是可行的,可以对现有的技术进行辅助和补充。     

Environmental inequality and pollution advantage among immigrants in the United States

Environmental inequality scholarship has paid little attention to the disproportional exposure of immigrants in the United States (U.S.) to unfavorable environmental conditions. This study investigates whether new international migrants in the U.S. are exposed to environmental hazards and how this pattern varies among immigrant subpopulations (e.g., Hispanics, Asian, European). We combine sociodemographic information from the American Community Survey with toxicity-weighted chemical concentrations (Toxics Release Inventory) to model the relationship between toxin exposure and the relative population of recent immigrants across Public Use Microdata Areas (PUMAs, n = 2054) during 2005–2011. Results from spatial panel models show that immigrants tend to be less exposed to toxins, suggesting resilience instead of vulnerability. This pattern was pronounced among immigrants from Europe and Latin America (excluding Mexico). However, our results revealed that Mexican immigrants are disproportionately exposed to environmental hazards in wealthy regions.
