ABSTRACT: The technology of urban stormwater management has far outpaced its actual application in new urban development. This article documents that implementation gap, but shows that state and local governmental measures, particularly storm drainage regulations, can lead to improved performance in the private sector. Although state stormwater management programs are in their infancy, they are already having a measurable effect in stimulating the adoption of local governmental programs to manage urban storm water. Pioneering state programs in Maryland, New Jersey, and Pennsylvania, described in this article, provide models for states contemplating the formulation of stormwater management programs.  相似文献

With the advent of Carbon Capture and Storage technology (CCS) the scale and extent of its handling is set to increase. Carbon dioxide (CO2) capture plants are expected to be situated near to power plants and other large industrial sources. Afterward CO2 is to be transported to storage site using one or a combination of transport media: truck, train, ship or pipeline. Transport by pipeline is considered the preferred option for large quantities of CO2 over long distances. The hazard connected with this kind of transportation can be considered an emerging risk and is the subject of this paper.The paper describes the Quantitative Risk Assessment of a hypothetical network pipeline located in UK, in particular the study of consequences due to a CO2 release from pipeline.The risk analysis highlighted that some sections of pipeline network cross densely populated areas. For this reason, some changes in the original path of the network have been proposed in order to achieve a significant reduction in the societal risk.  相似文献

Prescribed burning is now a widely accepted bushfire hazard management strategy. While evidence points to reduced levels of public health harm compared to severe bushfire, smoke created by planned burns remains a community concern with need for evidence-based public health management. Findings are presented from an Australian study of community experiences of prescribed burns, associated smoke, and public health communications. We find that “place” influences how information is received and used for the management of the effects of planned burns; and that this is significant for human agency and community resilience. We provide recommendations for public health management.  相似文献

The exemption for groundwater wells for residential uses from the prior appropriations system, common in the western United States, has eroded in Washington State since about 2000 due to a series of legal cases. Water markets can allow the transfer of an existing water right, typically from an agricultural use, to compensate for the effect of a new residential well. But water must be legally and physically available in a way suitable to satisfy mitigation requirements. A recent court case in the Skagit basin in Northwestern Washington State has effectively halted residential development in rural areas of the basin because no suitable water rights are available to purchase for mitigation. This paper presents and examines the cost‐effectiveness of various water supply mitigation strategies. We find a small‐scale, distributed stream‐side storage system for augmenting instream flow purchased from downstream sources is relatively cost‐effective to mitigate against the effects of domestic groundwater use compared to more common alternatives. We consider transporting water to storage sites by both small‐gauge pipe and by truck. Overall, trucking water to stream‐side storage and release points tends to be more cost‐effective to mitigate against indoor‐use only given current subbasin housing densities, whereas piping for direct streamflow augmentation is more cost‐effective for higher mitigation needs associated with indoor and outdoor use and higher housing densities.  相似文献

This paper seeks to better understand the possible paradox of frontrunners in experimental climate governance. This paradox refers to the situation where frontrunners are required to push boundaries in terms of developing governance innovations and to experiment with these, but where, at the same time, a too strong focus on frontrunners may result in a situation where lessons from these experiments and the innovations developed do not resonate with the majority. In such a situation, an innovation may not be capable of being scaled up or of being transferred to another context. This paper draws lessons from a series of nine experimental and innovative governance instruments for low-carbon building development and transformation in Australia. It points out that for these instruments the frontrunners paradox provides a partial explanation as to why they have not yet been able to scale up from a small group of industry leaders to the large majority.  相似文献

The roles and responsibilities of cities in CO2 mitigation have drawn increasing attention in recent years. To facilitate optimal design of effective mitigation policies, it is important for city authorities to understand the magnitudes and sources of their CO2 emissions, and their relative shares of emissions at a higher spatial level. Although several studies estimate CO2 emissions at the city level, the robustness of these estimates and their linkage to emissions at a higher level remains unclear. This kind of localized information on emissions is important for coordination of climate policies at different spatial scales. The study aims to fill a gap in understanding by building a systematic bottom-up approach for estimating urban CO2 emissions and offering a consistency check with IPCC top–down estimates. Using Taiwan as a case study, we display the geographic distribution of CO2 emissions. The significance and implications of the downscaling CO2 emissions are indicated accordingly.  相似文献
