绅士化是近十年人文地理学和城乡规划学持续关注的热门话题。在传统绅士化的基础上，学者们陆续提出了新建绅士化、教育绅士化、乡村绅士化、旅游绅士化以及环境绅士化等概念。其中，环境绅士化在近年尤受关注。本文首先对国外环境绅士化现有文献进行梳理和分析，对环境绅士化的概念、产生背景与影响进行介绍，认为环境绅士化是由环境美化或环境清理等环境改善实践所推动的地方物理空间品质提升、社会经济文化升级、弱势群体或低收入阶层直接或间接失所的过程。然后，分别从传统绅士化、环境不正义以及可持续发展内在矛盾视角对环境绅士化的相关研究进行了梳理，并特别基于环境不正义视角，对国外环境绅士化现有应对策略进行总结。最后对现有国外环境绅士化的研究进行总结与评述，并呼吁我国学术界和实践界关注由于快速生态环境治理和绿化美化所引发的环境绅士化现象。 相似文献

In 1976, the U.S. Congress enacted the Resource Conservation and Recovery Act (RCRA) to further address the problem of increasing industrial and municipal waste. The main objectives of RCRA were to responsibly manage hazardous and solid waste and to procure materials made from recovered wastes. To fulfill these objectives, four main programs of waste management were developed. These programs were defined under Subtitle C, the Hazardous Waste Program; Subtitle D, the Solid Waste Program; Subtitle I, the Underground Storage Tank Program; and Subtitle J, the Medical Waste Program. Subtitle D illustrates the solid waste dilemma occurring in the United States. Under this program, states are encouraged to develop and implement their own waste management plans. These plans include the promotion of recycling solid wastes and the closing and upgrading of all environmentally unsound dumps.Correspondence should be directed to Earle B.

Resource recycling reduces the amount of waste discharged into the global environment. The waste reduction achieved by thorough recycling is substantial. Recycling is thus an inseparable part of global environmental protection.We human beings have used mineral resources since the birth of our species. The quantities and increasingly complex forms in which mineral resources have been used at different times in our prehistory and history serve as indices of civilization's advancement. But on the eve of the 21st century, environmental pollution and global warming stemming from spiraling resource and energy consumption pose serious dilemmas for humanity. The rapidity with which our resource consumption has increased approximates exponential growth.The worsening condition of the earth's environment because of massive resource and energy consumption is the result of activity at many stages of production, from the mining of mineral resources to the manufacture of finished products; the culmination of the process is the disposal of products as waste after their use. As we shall see from examples given in this paper, efforts are being made to solve this problem through recycling; but in many areas the problems remain incompletely solved or unsolved altogether. 相似文献

In this article I consider the initial period of solid waste management planning in the US state of Hawaii. The State encountered a number of economic and ecological controversies during its solid waste management planning, a process that was prompted by the US Environmental Protection Agency. Some issues, like project financing, were common across the US, while others, such as the potential of waste materials to reduce reliance on imported food and materials, were more unique to Hawaii. The controversies from this initial planning period were never quite fully resolved; as they lingered, they were interpreted differently across the Islands. Based on a close reading of government, advocacy group, waste industry and news media documents, I examine the controversies over solid waste management of the time and consider how the ‘dual nature’ of waste in Hawaii—simultaneously an ecological threat and (potential) economic input—shaped the adoption of solid waste management systems there. This article adds to an expanding literature examining infrastructure in environmental and technology histories. 相似文献

Recent years have seen a rapid rise in the political saliency of the ever growing volumes of municipal waste produced in the UK. In this paper, we examine how one particular part of the municipal waste stream – biodegradable waste – has come under the policy spotlight. As targets to divert biodegradable waste from landfill under the Landfill Directive come into force, the need to focus explicitly on recovering value from biodegradable materials has risen up national and local policy agendas, not least with the introduction of the Landfill Allowance Trading Scheme. Accompanying this new rationality for managing waste has been a suite of different policy interventions. In this paper we examine the impact of the changing nature of municipal waste policy and the ways in which it has sought to rework the disposal and collection of biodegradable waste. We argue that the predominantly technical framing and instrumental rationality of these interventions does not sufficiently challenge entrenched understandings regarding the boundaries between public and private responsibility for waste, and thus short-circuits their capacity to engage with everyday community/individual waste practices. In conclusion, we suggest that, in order to move waste management towards sustainability, there is a need both to engage with the institutional and infrastructural dimensions of the systems of provision within which waste management occurs, and to take seriously the everyday contexts within which making waste is practiced. 相似文献

This work deals with the identification of potentially contaminated areas using remote sensing, geographic information systems (GIS) and multi‐criteria spatial analysis. The identification of unknown illegal landfills is a crucial environmental problem in all developed and developing countries, where a large number of illegal waste deposits exist as a result of fast, and relatively unregulated, industrial growth over the past century. The criteria used to perform the spatial analysis are here selected by considering the characteristics which are ‘desirable’ for an illegal waste disposal site, chiefly related to the existence of roads for easy access and to a low population density which facilitates unnoticed dumping of illegal waste materials. A large dataset describing known legal and illegal landfills and the context of their location (population, road network, etc.) was used to perform a spatial statistical analysis to select factors and criteria allowing for the identification of the known waste deposits. The final result is a map describing the likelihood of an illegal waste deposit to be located at any arbitrary location. Such a probability map is then used together with remote sensing techniques to narrow down the set of possibly contaminated sites (Silvestri and Omri, 2008), which are candidates for further analyses and field investigations. The importance of the integration of GIS and remote sensing is highlighted and represents a key instrument for environmental management and for the spatially‐distributed characterization of possible uncontrolled landfill sites. 相似文献

Due to the increasing pressure from the European Union, in the last decade the waste management landscape in Greece has been going through drastic changes, especially regarding policies and legislation. Shifts in management practices, however, have been considerably slower. A major component of this shift is the requirement by the Landfill Directive (LD) to divert increasing quantities of biodegradable municipal waste (BMW) from landfilling. Making use of the four-year extension allowed to countries heavily reliant on landfills, Greece will have to achieve the LD diversion targets in the period 2010–2020. In this paper the main aspects of the LD are outlined and critically placed in the context of the EU waste policy and the priorities of the new Waste Directive. The current state of waste management in Greece is presented with the main planning for new BMW treatment infrastructure. The complex and multifaceted barriers to successful implementation of waste policies in Greece are discussed using the case study of the LD, in an effort to draw lessons for the New Member States. 相似文献

The first factor determining recyclability is the composition of the material itself. Metals, for example, can be reused with little or no loss in quality. Paper and rubber, by this criterion, are less recyclable. Each time paper is recycled, some cellulose fibers are broken. Shorter fibers can mean weaker paper of perceived lower quality and value. Vulcanizing is an irreversible chemical process that precludes recycling rubber in its original form. Both materials may be reused in other applications often of lower value than the original one. To be recyclable, the discarded material must have a collection infrastructure at the source of waste generation, at a central collection site, or at curbside. The recovered material must also have a market. If it is priced noncompetitively or no market exists, if it does not meet specifications, or if it requires special technology investments which cannot be recovered through future sales, the recovered material may be stockpiled or discarded rather than recycled.Correspondence should be directed to: Earle B.
