This article presents a survey of Neolithic economy, land use, trade, natural environment, and usage of plant and animal resources in central Europe, 5415–2240 B.C. (4500–1800 bc). Early, Middle A and B and Late Neolithic materials are summarized and compared. The earliest farmers expanded from southern Hungary and adjacent areas into central Europe over a relatively short time period, 100–200 years. They occupied areas only with good soils; thus probably hunters and gatherers continued to exist in many regions of central Europe. There is an increase in population and more upland areas are exploited for farming during the Middle Neolithic A and B periods. By the Middle Neolithic B period, low-level hierarchical or ranked societies appear in some regions of central Europe. The Late Neolithic may represent a modification of the mixed farming strategy observed during the earlier periods. Perhaps the herding of domestic animals became more important.  相似文献

Global energy policies embracing a transition to unconventional oil and gas development are hallmarks of many developed nations. Among these, the United Kingdom has framed the development of shale gas as one means to transition from high-carbon fossil-fuel consumption to low-carbon alternatives. Yet the introduction of this industry and recent legislation associated with it have not been without controversy. Communities throughout the United Kingdom are engaged in sustained debates concerning climate change, health, the scale of extraction footprints, securitisation, and governance. Places such as Kirby Misperton, the focus of this article, are representative of many villages where questions abound about the role of justice at all stages and scales of governmental decision-making. Using a legal geographic lens, this article examines narratives among local residents who are actively resisting the arrival of unconventional gas. I consider how the relationships between and among energy transition, policy, and justice have been interpreted by communities and argue for inequity and risk to be addressed in more transparent ways. I contend that highlighting counter-narratives remains essential if powerful arguments by governments and others are to be negated. Fundamentally, true justice can only prevail when all stakeholders are considered legitimate and their opinions valid.  相似文献

Scientists advise limiting global warming to 1.5°C with substantial actions by 2030. Our viewpoint argues that climate response strategies in Canada have underemphasized and underestimated the potential contribution deep energy retrofits can make to greenhouse gas (GHG) emissions reductions, leading to inadequate responses in the building sector, and that Canada can (and should) be ambitious with building retrofits over the next decade. GHG savings from building retrofits can be realized more quickly than GHG reductions from other sectors, and either deliver net cost savings or are cost‐effective when compared to other mitigation measures. Retrofits can also provide social and economic benefits, such as improved health and comfort, and lower energy costs. This paper reviews energy use and building retrofits in Canada and argues the following should be implemented: (1) focus innovation on deep energy retrofit processes, not singular retrofit actions; (2) maximize both social and environmental benefits; (3) improve data gathering and availability for analysis and delivery; (4) innovate for a process of decisions and to avoid “dropouts” during the retrofit process; and (5) focus innovation on business models that maximize benefits.  相似文献

Community renewable energy (CRE) represents a growing empirical and academic turn towards community‐based sustainability and climate change interventions. This paper brings together postcolonial theory and CRE for the first time to outline fundamental tensions in the conceptualisation and application of the idea of community. The understanding of community within the CRE discourse is largely: (1) location‐based; and/or (2) a community of choice that is consciously opted into. Driven by postcolonial theory, this paper counterpoises both as a form of community as contract against an idea of community as solidarity. Its central thesis is that actually existing community, contrary to how the bulk of CRE literature commonly understands it, is a combination of bonds of solidarity and emergent purposes. The paper conceptualises community as fluid bonds of solidarity that align and realign differently around different purposes.  相似文献

Non-urbanized areas (NUAs) play an important role in reducing the effects of climate change by providing both carbon storage and sequestration. Urban areas are responsible for the emission of 60% of global greenhouse gas, 50% of which are produced by buildings. During the past decades, increasing urban growth and sprawl processes produced several urban layouts characterized by different morphological features and a common lack of sustainable energy and environmental solutions. Investigating the relationship between urban morphology, energy demand and carbon emission/sequestration represents a relevant topic for urban planning practices implemented to face urban climate change effects. This study proposes a method for a transformability assessment aimed at investigating the transformation suitability of different urban morphology types. The case study is the metropolitan area of Catania (Italy), characterized by an impressive urban growth since the 1960s. The proposed method identification of limits and options for increasing sustainability of urban areas considering the contribution of both NUAs and built-up areas. This approach allows to identify appropriate planning tools for new layouts of urban fabrics while increasing the objectivity of the decision process. In the framework of climate change mitigation and adaptation, the outcomes of this research may lead to innovative urban planning practices.  相似文献

The aim of this paper was to develop a social sustainability tool to clarify what social sustainability means in land use planning processes. The tool was developed through a robust research process covering a large amount of scientific literature and built environment sustainability assessment tools. To assess how the developed tool works in practice, we used it as a coding system for the assessment of social sustainability in a case study from Finland. The case study includes the master planning process of a medium-sized city and the legal framework guiding it. The theoretical contribution of the paper lies in creating a holistic tool for the assessment of social sustainability in planning processes. This study also provides a strong practical contribution, as it goes beyond theoretical definitions to the pragmatic level by providing exemplary measures to be used in designing and implementing processes. Therefore, this paper is a valuable source for those stakeholders (for example planners, developers and policymakers), who struggle with the issue of the successful implementation of social sustainability practices, and it will help them to benchmark their processes against the themes found in the tool.  相似文献

Giorgio Agamben lists the Jewish Sabbath as an example of “inoperatvity.” This essay explores both how Sabbath fits into and puts pressure on Agamben’s account, by working through readings of the Sabbath given by Agamben, A.J. Heschel, and Rosenzweig, who associate Sabbath, respectively, with Inoperativity, Eternity, and Creation. To these, I add another, called the Sabbath of Equality, building on connections among the weekly Sabbath, the septannual land Sabbatical and the Sabbath of Sabbaths, the Jubilee. The reading of Rosenzweig, in particular, opens the way to a queering of Sabbath, also explored here. The essay concludes with the suggestion that Hannah Arendt’s political thought is “sabbatarian” and asks whether this is an effective way to respond to earlier critiques of her work for promoting an “aestheticized” politics not adequately oriented to use. Is Agamben vulnerable to the same critique now?  相似文献

简析中日能源联合议价的成本收益   总被引:1,自引:1,他引:0  
作为世界第二和第三的大能源消费国,中国和日本在分散竞争的条件下承受了过多的进口成本。本文在分析能源商品的价格决定因素基础上,探讨中日两国进行能源联合议价的成本与收益。认为这种努力可以在消除能源的亚洲溢价、减少能源竞争成本、促进亚洲能源期货市场发展、增强区域经济联系等方面获得显著收益。同时,联合议价的经济成本比较小,国家安全成本和政治成本则在两国之间存在不对称性,并且难以量化。  相似文献

Archaeological research in the Mimbres region (southwestern New Mexico) has focused on the post-A.D. 500 ceramic/agricultural occupations, especially the Mimbres Classic period (1000–1130). This work has advanced general anthropological issues regarding mobility, land use and human impact, and the concept of abandonment. Deeper understandings of some of these issues require more detailed demographic estimates, which in turn are dependent on methodological advances, particularly studies of site use life. Research on the production and distribution of Mimbres pottery—famous for its naturalistic black-on-white designs—is advancing rapidly. Although the designs have been well illustrated and much discussed, more systematic anthropological research on Mimbres design style is badly needed. Various aspects of Mimbres social and ideational realms (e.g., household and community organization, social hierarchy, the symbolism of the pottery designs) have received some attention but await new perspectives derived from current social theory.  相似文献
