It’s All in the Numbers: Acreage Tallies and Environmental Program Evaluation

Increasingly, performance measurement is being used to hold federal agencies accountable, represent environmental progress, and evaluate the effectiveness of environmental programs. The need to track measurable outputs has created a tendency to present programmatic progress solely by quantifiable data, despite the inherent complexity of natural resource management. Wetlands and fire management programs are two specific environmental arenas that have come to overemphasize the tracking of acreage numbers to validate existing policy direction. In both of these arenas, we find the definition and categorization of "countable" acres to be inconsistent and unreliable. We explore this systemic flaw for both wetlands and fire programs and describe its implications for environmental policy and natural resource management more broadly. We conclude with recommendations for improved performance measurement in these arenas.

Morphologie effects of channelization: the case of the Neebing-McIntyre floodway,Thunder Bay,Ontario, Canada

The Neebing-McIntyre floodway in Thunder Bay, Ontario, Canada, has been constructed with a relatively straight and uniform trapezoidal channel, compared with the prechannelized sinuous reaches of the Neebing and the McIntyre rivers. The flow regime of the floodway also contrasts significantly with the prechannelized regime, because of the combination of discharges from these rivers into a new channel and the regulation of flows by a diversion structure. The maximum channel capacity of the floodway is about 284 m³ s^–1 (175-year regional flood), compared with about 40 m³ s^–1 and 60 m³ s^–1, respectively, for the Neebing and the McIntyre. According to regime theories, the construction of a straight and trapezoidal channel has upset the equilibrium of the stream system and therefore should lead to some accelerated erosion and sedimentation processes in the new channel immediately after construction. Erosion potential is particularly high during higher discharge events, when flow velocities are expected to be greater than the prechannelized velocities of the Neebing and the McIntyre. The overall sediment yield of the watershed is low (71t km^–2 yr^–1), compared with other documented watersheds of North America, but the rates of deposition in the floodway are relatively high, mainly due to the backwater effect of Lake Superior. Unless maintained by constant channel work, the floodway will tend to fill up with sediment, until a postconstructional equilibrium is reestablished.     

Development of a Methodology for Selecting Criteria and Indicators of Sustainable Forest Management: A Case Study on Participatory Assessment

This paper describes an application of multiple criteria analysis (MCA) in assessing criteria and indicators adapted for a particular forest management unit. The methods include: ranking, rating, and pairwise comparisons. These methods were used in a participatory decision-making environment where a team representing various stakeholders and professionals used their expert opinions and judgements in assessing different criteria and indicators (C&I) on the one hand, and how suitable and applicable they are to a forest management unit on the other. A forest concession located in Kalimantan, Indonesia, was used as the site for the case study. Results from the study show that the multicriteria methods are effective tools that can be used as structured decision aids to evaluate, prioritize, and select sets of C&I for a particular forest management unit. Ranking and rating approaches can be used as a screening tool to develop an initial list of C&I. Pairwise comparison, on the other hand, can be used as a finer filter to further reduce the list. In addition to using these three MCA methods, the study also examines two commonly used group decision-making techniques, the Delphi method and the nominal group technique. Feedback received from the participants indicates that the methods are transparent, easy to implement, and provide a convenient environment for participatory decision-making.

关于秦皇岛市竞争力的初步分析及对策研究

我国城市竞争力研究成果表明秦皇岛市综合竞争力在全国排序第39位,基础设施、环境、区位等硬竞争力较强,而企业管理、制度、文化等软竞争力较弱,因此虽然在河北省名列前茅,但在沿海城市中比较落后,为了增强城市竞争力,必须正确定位、协调发展;发挥优势、加快发展;加快招商引资;进一步开放;加快科技进步,加强精神文明建设;强化城市营销和品牌建设;强化城市和企业管理。     

浅析黄河三角洲地区土地开发整理中的农业生态环境保护问题

土地开发整理是一项旨在提高土地生产力,改善农业生产条件和生态环境的活动,本文从目前黄河三角洲地区实际土地开发整理的情况分析,通过土地开发整理增加耕地面积,提高土地生产力,进一步呼吁对农业生态环境保护这一目标加强重视,形成一整套完整的土地开发整理生态绩效的评价体系和方法,以利于土地经济和土地生态的均衡发展。从生态学的角度对这一问题做出了比较全面的思考。     

半导体企业的EHSMS评价体系研究

为了给员工提供安全、环保、健康的工作环境,半导体制造企业必须建立环境管理和职业健康安全管理体系(EHSMS).为此,评价EHSMS运行的有效性、完整性以及合法性就显得十分重要.本文在分析半导体企业污染物影响环境和健康基础上,建立了EHSMS评估体系.为了实施EHSM评估系统,方便半导体企业用户使用,提出了一套EHSM评价系统的计算机软件解决方案.
