Reclaiming A. D. Gordon's deep eco-nationalism

This study seeks to add to the burgeoning literature on the relations between nationalism and environmentalism by examining the ideas of A. D. Gordon (1856–1922). Gordon is not well-known outside the realm of Zionist scholarship. Nonetheless, a close re-examination of his ideas reveals that Gordon offers a hybrid brand of deep eco-national theory that frames traditional deep ecological themes within a general theory of nationalism. Whereas Gordon's theory introduces the ‘nation’ as a central notion to deep ecology thought, at the same time, it adds an ecological dimension rarely taken into account in theories of nationalism. This analysis further shows that although Gordon's pioneering eco-national theory had high potential for bridging between the two disciplines, it eventually faded into obscurity like eco-national ideas elsewhere. As Jewish national independence came into view, Gordon's distinctive eco-nationalism was overshadowed by anthropocentric-based Zionist politics.     

How housing,infrastructure and water determined the spatial structure of the Randstad

Between 1950 and 1990, housing was the driving force behind the spatial growth of the Randstad. Growth poles (1970s) and later VINEX locations (1990–2010) were the main components of growth management. Transport infrastructure has developed greatly since the 1920s. Since 1990, infrastructure development has increasingly become the structuring force for the spatial dynamics of the Randstad. Schiphol was seen as the mainport for airlines, and Rotterdam-Europoort as the mainport for shipping lines and container transport. The landside infrastructural connections for Schiphol and Europoort had a big impact on the growth in the capacity of continental roads and rail lines. ICT- and energy infrastructure are now developing quickly. Recently, Amsterdam Internet Exchange became the largest ICT node in Europe. Finally, the Delta programme was introduced, strengthening the coastal areas and leaving more room for the rivers. For the future, a combination of housing, infrastructure and water for spatial developments will determine the spatial structure of the Randstad further. A compartmentalized plan of the Randstad between the main dikes is presented, which will increase the resilience of functions of the Randstad in the future when the North Sea level is expected to rise substantially. The analysis presented could be relevant for many urban deltas worldwide.     

The ‘natures’ of planning: evolving conceptualizations of nature as expressed in urban planning theory and practice

Over the course of the past century, the idea of nature in the city has become increasingly intricate, evolving from being viewed as a refuge separate from the city to being understood as an essential component of dynamic urban systems. As such, attempts are currently being made to ‘re-nature’ cities to support local and global ecosystems, increase human well-being and address environmental issues such as climate change. While the literature has examined changing assumptions about society–nature relationships in planning, a dearth of knowledge exists relating to the changing conceptualization of nature’s relationship with the ‘city’ and how this has influenced how urban planning with respect to ‘nature’ has evolved in both theory ‘and’ practice. In this paper, we address this lacuna by tracing the history of the entwined relationship between nature and city planning. The conceptual framework developed from this review is subsequently employed as an analytical lens through which to investigate an illustrative case study of planning for nature in Dublin City, Ireland. The paper concludes by reflecting on how exploring the natures of planning provides scope for greater critical attention to what we do as planners when we seek to address the challenge of safeguarding nature through policy.     

慈溪越窑和洪州窑瓷片的X荧光分析研究

用能量色散型X荧光分析仪测量了慈溪寺龙口等6个越窑窑址和洪州窑4个窑址出土瓷片胎釉的化学组成。在两地均观察到近距离窑址出土瓷胎间化学组成的差异,观察到越窑瓷釉配方的稳定性和南宋晚期时的明显进步,提出了洪州青瓷中铁含量从东汉到晚唐的马鞍形变化,可能反映洪州窑在晚唐的衰落和低铁原料的不易获得。     

我国绿色农业布局问题研究

绿色农业是一种新的农业生产方式。本文探讨了绿色农业的基本含义,分析了我国绿色农业发展、布局中存在的优势和问题,认为绿色农业将成为我国农业的主导产业部门,其结构是以绿色粮食生产为基础,以绿色经济作物和绿色畜牧业为主体,并包括绿色林特产品采集和绿色养殖业在内的综合农业。全国范围内可划分为九个绿色农业区。按照比较优势、市场导向、因地制宜和地域相对集中等原则,要重点建设14个绿色农业类型,并进一步研究了我国绿色农业合理布局的对策     

GREEN GROWTH OR ECOLOGICAL COMMODIFICATION: DEBATING THE GREEN ECONOMY IN THE GLOBAL SOUTH

This article examines recent institutional thinking on the green economy and the implications of official understandings and structuration of a green economy for the global South. Assertions about the transformative potential of a green economy by many international actors conceals a complexity of problems, including the degree to which the green economy is still based on old fossil economies and technical fixes, and the processes through which the green economy ideation remains subject to Northern economic and technical dominance. The article places the intellectual roots of the green economy within a broader historical context and suggests some ways the strategic economic and ideological interests of the global North remain key drivers of green‐economy thinking. The analysis is substantiated through two illustrative Latin American examples: the Mesoamerican Biological Corridor and green economy initiatives in Brazil. These suggest that, if the green economy is to address global challenges effectively, it must be conceptualized as more than a bolt‐on to existing globalizing capitalism and encompass more critical understandings of the complex socio‐economic processes through which poverty is produced and reproduced and through which the global environment is being transformed, a critique which also applies to mainstream discourses of sustainable development.     

城市绿地服务功能的居民认知度研究

城市绿地作为城市中公共场所和自然元素,担当着多种功能。而居民对城市绿地各种服务功能的认知度受到自身主观因素和所处绿地环境因素的影响。本文通过问卷对南京市居民绿地服务功能认知进行调查,从居民绿地服务功能重要性认知、服务功能感知两方面分析居民认知度及其影响因素。结果表明:居民对各服务功能的感知程度与其重要性认知结果大体一致,对绿地的生态环境功能感知度低于其主观重要性认知水平;居民自身主观因素中的年龄和文化程度、所处绿地数量和植物种类对居民的感知程度和重要性认知有显著影响。     

四川广元千佛崖石窟绿色颜料分析研究

千佛崖石窟位于广元市城北5㎞嘉陵江东岸,现存54窟、819龛、大小造像7000余身,这些珍贵文化遗产具有极高的艺术及科研价值。2008年由于受到汶川地震的影响,很多彩绘佛造像损毁情况严重,修复工作亟待进行。为此,本研究以四川千佛崖采集的7个样品的绿色颜料为研究对象,利用金相显微分析、偏光显微分析、拉曼光谱分析技术对其进行物象和成分分析。分析结果表明,千佛崖采用的绿色颜料主要为人工合成的氯铜矿和石绿,还有少量的巴黎绿,且处于颜料最外层,应为近代重新修复所施加的;同时,对于碱式氯化铜及其相关物质、石绿、巴黎绿在中国的使用情况及其应用特点进行探讨,以期对后期的保护工作提供借鉴作用。     

说酒·绿酒

在我国古代诗中,提到酒,特别是质量上乘的好酒,或称赞美酒时,常称作“绿酒”,“绿蚁”等等,并由此衍生出“灯红酒绿”这样的成语,本从古代酿酒工艺等方面探讨了酒在一般情况下都不是绿颜色,称它为绿色,只是强调酒液清澈。     

“Fixing” Climate Change by Mortgaging the Future: Negative Emissions,Spatiotemporal Fixes,and the Political Economy of Delay

Models suggest that climate change mitigation now depends on negative emissions, i.e. the large‐scale removal of carbon dioxide from the atmosphere. This assumption has been criticised in the climate policy literature for being unfeasible and unjust. This article asks how critical scholars can make sense of, and contribute to these debates. It suggests that negative emissions can be conceived of as a spatiotemporal fix that promises to defer the devaluation of fixed capital. But the negative emissions example also challenges us to broaden our conception of how the socioecological contradictions of capitalism can be “fixed”. I outline three ways in which it does this by highlighting the significance of a predominantly temporal fix, the role of hegemonic, sociopolitical interventions involving multiple actors, and the possibility of safeguarding existing production processes. I conclude that spatiotemporal fixes to climate change should be seen as part of a wider political economy of delay in devaluing carbon‐intensive accumulation processes.
