Yasamis FD 《Environmental management》2006,38(5):823-836
Improving the performance of the state environmental agencies (SEAs) necessitates an effective institutionalization of governmental
environmental management functions. There are examples of successful and unsuccessful SEAs in several parts of the world.
Analysis and assessment of these cases can deliver useful insights for institution builders. The objective of this article
is the assessment of the institutional effectiveness of the SEAs in Turkey through the perceptions of the experts using the
Delphi Technique. In this regard, a checklist is developed including 16 criteria and 123 subcriteria to measure the institutional
effectiveness of the SEAs. Twenty-eight national and international experts have formed a Delphi panel and evaluated the national
and local conditions. Results, based on the perceptions of the experts, indicate that the overall effectiveness of the SEAs
is far less than satisfactory. Negative consensus has been reached over the effectiveness of 13 of the16 criteria and 95 of
the123 subcriteria; however, no consensus has been achieved over the remainder of the parameters. The survey has also proven
that the Delphi Technique can be effectively used for that purpose. Utilization of the checklist method is also useful in
diagnosing the problematic components of the SEAs. It is recommended that this approach be used in similar cases elsewhere. 相似文献

Applying Integrated Urban Water Management Concepts: A Review of Australian Experience 总被引:2,自引:0,他引:2
Mitchell VG 《Environmental management》2006,37(5):589-605
This article explores recent Australian experiences in the application of the concept of integrated urban water management
(IUWM) to land development sites through the review of 15 case studies. It discusses lUWM’s emergence and comments on the
success or otherwise of Australian experience in its application. The understanding of IUWM is maturing within the Australian
water industry, an occurrence that has been facilitated by demonstration sites such as those reviewed. Successes include the
translation of IUWM concepts into well-functioning operational urban developments, significant reductions in the impact of
the urban developments on the total water cycle, and the increasing acceptance of the concept within the water and land development
industries. However, there is still room for greater integration of the water supply, stormwater, and wastewater components
of the urban water cycle, improved dissemination of knowledge, enhancement of skills in both public and private organisations,
and monitoring the performance of systems and technologies. 相似文献

ABSTRACTIn this Forum, three scholars discuss how climate engineering will pose novel human rights challenges, and may well force reconsideration of how human rights are applied as a guide to action. Following a short introduction, the first section introduces three competing approaches to human rights, arguing views which emphasize fairness or attempt to maximize satisfaction are more promising than one viewing human rights as inviolable ‘side-constraints’. The second section draws lessons from climate migration that are relevant for climate engineering in terms of incorporating a human rights approach to duties, rights, and participation. The final section compares the ‘needs-based’ and ‘rights-based’ approaches to humanitarian work in the face of climate change and climate engineering, raising concerns for duty-bearers and right-holders. The Forum’s conclusion draws together points of overlap and suggests a path forward for policy and research on this topic. 相似文献

土壤碳库管理指数(CPMI)是表征土壤碳库变化的一个重要量化指标,能够反映土壤的碳库变化和碳库质量。选取庐山8种森林植被类型土壤为研究对象,对其土壤有机碳库特征及碳库管理指数进行系统研究。结论表明:(1)土壤有机碳(SOC)主要分布于0~20 cm土层中,随着土层深度增加,不同森林植被类型下SOC含量急剧下降;在0~60 cm土层中,不同森林植被类型下SOC含量的平均值排序为:马尾松林常绿阔叶林灌丛针阔混交林常绿-落叶混交林黄山松林落叶阔叶林竹林。(2)不同森林植被类型下活性有机碳(ASOC)含量为0.24~0.57 g·kg–1,总有机碳(TOC)含量为9.72~14.74 g·kg–1,土壤碳库指数(CPI)为1.63~2.48,碳库活度(A)为0.019~0.062,碳库活度指数(AI)为0.388~1.265。不同森林植被类型下ASOC含量排序:落叶阔叶林黄山松林常绿-落叶阔叶混交林灌丛针阔混交林常绿阔叶林竹林马尾松林;不同森林植被类型下ASOC/TOC(%)排序:落叶阔叶林黄山松林常绿-落叶阔叶混交林竹林灌丛针阔混交林常绿阔叶林马尾松林;不同森林植被类型下CPMI排序为:落叶阔叶林黄山松林常绿-落叶阔叶混交林灌丛针阔混交林常绿阔叶林竹林马尾松林。 相似文献

This paper considers a two-echelon closed-loop supply chain consisting of a manufacturer and a remanufacturer at the upper echelon and a retailer at the lower echelon. The retailer faces a constant demand from customers, which is satisfied through recovered and new products received from the remanufacturer and the manufacturer, respectively. The manufacturer produces the product with finite rate, whereas the recovery of returned product is instantaneous at the remanufacturer. We develop three models to determine the optimal production-inventory policy of the players for minimizing the joint total cost of the system. In the first model, the retailer receives the product in batches from the manufacturer and the remanufacture simultaneously, whereas in the second and third models, the batches are received alternatively. In the third model, however, the procurement of raw material at the manufacturer is also considered. Numerical illustration is presented to examine the impact of certain key parameters. 相似文献

基于效果-效率-适应性的养殖废弃物资源化利用管理模式评价框架构建及初步应用 总被引:4,自引:0,他引:4
由于产业发展正处于转型阶段,我国畜禽养殖污染治理中的管理问题比技术问题更加突出,选择适宜的组织管理模式尤其重要。融合了效果分析、效率评价和适应性分析,尝试构建一个养殖废弃物资源化利用管理模式综合评价框架,并选择太湖流域4个不同类型的典型案例进行方法例证。研究表明,传统的养殖企业主导型管理模式应用于小型、分散养殖废弃物资源化利用时面临着经济效率低、适应性差难题;农村废弃物处理中心、种植企业和有机肥企业的参与可以改善小型、分散养殖废弃物资源化利用的经济效率;综合考虑效果、效率与适应性,种植企业、有机肥企业主导型模式的适宜推广范围更广。应根据不同地区种植-养殖产业关系、污染治理需求、经济发展水平与政府投入能力等,灵活组合应用不同管理模式。 相似文献

Collaborative emergency management: better community organising, better public preparedness and response 总被引:3,自引:0,他引:3
Kapucu N 《Disasters》2008,32(2):239-262
Community coordination requires communication and planning of precautions to take when faced with a severe threat of disaster. The unique case of the four Florida hurricanes of 2004--Charley, Frances, Ivan, and Jeanne--is used here to assess community responses to repeated threats of hurricanes. The paper examines how effectiveness in coordinating community disaster response efforts affects future public preparedness. The findings suggest that pre-season planning, open communication between emergency managers and elected officials, and the use of technology all had a significant impact on community responses. The repeated threat scenario indicates that emergency managers must work vigilantly to keep residents informed of the seriousness of a situation. The study describes how emergency managers in Florida countered public complacency during four hurricanes in six weeks. The strategies identified as useful by public managers in the context of hurricanes are applicable to other natural and man-made disasters. 相似文献

基于现代信息技术的城市灾害应急管理系统 总被引:6,自引:0,他引:6
城市灾害应急管理系统是一项复杂的大系统工程。本文着重从应急管理过程中的应急资源调配、应急预案制定等方面阐述了现代信息技术在城市灾害应急管理中的应用与优势。认为应急管理信息系统的建立目的不是为了预测和估算,而应是当灾害发生时,对已造成的灾情局面做出快速的辅助决策支持。基于此,利用SuperMapObject5.0,Visual Basic6.0,SQL Server2000等现代信息技术软件,以辅助决策、资源快速查询以及生命线管网易损处调查为目的,本文建立了一个局部地区灾害应急管理信息系统。系统的数据库建立更突出了为应急管理服务所需的基础信息、空间数据、应急预案和应急资源等信息划分方式;结合已有的震害预测理论和方法,开发了供水系统和交通系统的震害预测模块,事先为灾害应急决策提供可能的震害信息。系统的开发过程进一步证明了GIS在城市灾害应急管理中有着直观显示、容易操作、辅助准确决策等优势。 相似文献
