Evaluating Management of Protected Areas: Integrating Planning and Evaluation

/ An approach to evaluating the effectiveness of management of protected areas is proposed. This approach has been used in developing an evaluation strategy for the Fraser Island World Heritage Area in Australia. The main component of the strategy is built upon the desired outcomes specified in the management plan for the area and thus provides a basis for assessing the extent to which the plan's objectives are being achieved. A series of monitoring programs have been proposed to enable this assessment. Examples of monitoring programs developed as part of the evaluation strategy are presented. A second component of the strategy monitors the implementation of the management plan. A management information system has been developed to record and report on the extent to which the specific actions specified in the management plan have been implemented. The strategy is discussed in relation to seven objectives set for the evaluation program in its design phase.KEY WORDS: Planning; Evaluation; Monitoring; Management; Protected areas     

国外环境政策评估体系研究——基于美国、欧盟的比较

用主成分分析的方法,找出影响废黄河2007年水质的主成分,计算各样本的主成分得分,用聚类分析的方法将样本水质分类,结合分类结果及水质综合评分对各样本水质进行评价。     

环境监测数据结果评价

环境监测是为了获得准确的环境信息数据,以便为环境评价、环境管理和环境治理提供依据。监测数据是否具有代表性,必须通过数据分析才能确定。文章通过介绍对监测数据的精密性、准确性和合理性检验,论述了监测数据的代表性。     

沈阳细河水体黑臭评价

根据1999-2008年监测数据,应用黑臭评价指数对沈阳细河水体进行黑臭评价。结果显示,细河水体黑臭指数,在1999-2003年间呈上升态势,2004年起逐年下降;1999-2006年,细河水体污染较重,呈严重黑臭状态,2007和2008两年,水质状况有所好转,呈微黑臭状态。     

Assessment of a large watershed in Brazil using Emergy Evaluation and Geographical Information System

Humanity's future depends on the preservation of natural ecosystems that supply resources and absorb pollutants. Rural and urban productions are currently based on chemical products made from petroleum, which are responsible for high negative impacts on the Biosphere. In order to prevent those impacts, efficient public policies seeking for sustainable development are necessary. Aiming to assess the load on the environment (considering the gratuitous contributions of natural systems—a donor's perspective) due to human-dominated process, a scientific tool called Emergy Evaluation has been applied in different production systems, including crops and farms. However, there is still a lack of emergy studies in the context of watersheds, probably due to the difficulty of collecting raw data. The present work aims to carry out an assessment of Mogi-Guaçu and Pardo watershed, through the combined use of Emergy Evaluation and Geographical Information System. The agricultural and natural land uses were considered, while urban areas were excluded. Emergy flows (expressed in seJ ha⁻¹ yr⁻¹) obtained for all agricultural and natural land uses were expanded for the whole watershed and the emergy indices were calculated. The results show that the watershed has: low renewability (%R = 32%); low capture of natural resources through high external economic investment (EYR = 1.86); low dependence on natural resources (EIR = 1.16); and moderate load on the environment (ELR = 2.08). Considering a scenario where sugar-cane crops, orchards and pasture areas are converted from conventional to organic management, watershed's emergy performance improved, reaching a new renewability of 38%, but it is still not enough to be considered sustainable.     

Assessing Public Participation Techniques for Comfort, Convenience, Satisfaction, and Deliberation

Public participatory techniques have been the focus of a large and growing body of environmental literature. There is some consensus among those who study these techniques that there is a need to develop and implement new techniques that meet certain criteria. These include that the techniques be comfortable, convenient, and satisfying to participants. Authors have also frequently called for the use of deliberative techniques, which allow participants to express and listen to a variety of perspectives regarding the issue at hand. However, the literature on public participation lacks a set of widely applicable evaluation methods to determine whether participants in techniques find them comfortable, convenient, satisfying, or deliberative. This paper reports on the implementation of two different techniques that participants scored fairly high on all of these factors, as well as the scale-based survey questions developed to measure these factors.

纳污湿地上覆水中重金属的监测及评价

以武河湿地为研究区域采集上覆水水样,采用ICP-AES法测定湿地水体中重金属的含量,参照有关标准用水质标准级别法对水中重金属污染情况进行了评价。结果表明:武河湿地中重金属Hg污染十分严重,各采样点均有分布且水质属劣Ⅴ类。重金属元素Cd污染并不严重,总体水质较好。重金属元素As、Cr、Cu、Pb在武河湿地中污染较轻近乎无污染,水质为Ⅰ类。由于重金属Hg的污染十分严重所以研究区内综合质量等级在4以上,水质为Ⅴ类和劣Ⅴ类,污染严重。
