Specifying information needs: improving the working methodology   总被引:1,自引:1,他引:0  
Specification of information needs is an important step in the design of monitoring networks. Within the framework of Monitoring Strategy 2000+, a programme of the Dutch Directorate General of Public Works and Water Management (Rijkswaterstaat) which seeks to provide innovation in the monitoring sector, a method has been developed to link water management policy to monitoring through specification of information needs. Over the past 2 years, this method has been applied in several projects within the Rijkswaterstaat organisation. Use of this method has led to improvements in the monitoring practice and was judged very positively by the people involved. Nevertheless, the main obstacle to employing the method was the actual translation of policy matters into information products. A special study is carried out, focusing on this aspect within the method, to provide the participants of a project with a mental framework that enables them to clearly specify their information needs. The major requirements for this mental framework are that all participants have a clear view of the process (system), and that they are able to relate their contribution to this process and to the contributions of others (transparency). The first step of the process is to focus the attention of stakeholders on the information they will actually need for decision-making. The next step is to confront the different expressed opinions through the method of the 'devil's advocate', which implies criticising the results of the first step by finding as many as possible arguments against these opinions. This should force the stakeholders to better specify their arguments. The method, its improvements and the results of one pilot project will be discussed in this paper.

Botswana is a rapidly developing country in southern Africa. Over the last three decades, diamond mining and tourism have provided double-digit rates of economic growth. Yet most of Botswana’s land is in the Kalahari desert where the climate is subject to sustained periods of severe drought. In this environment, water resources are the most crucial of all environmental resources. Water use directly affects economic development because water utilization impacts all the major national economic sectors. A sustainable water use resource management plan must stretch several decades into the future to assure the availability of adequate supplies of water to future generations while not compromising the ability of the current generation to reasonable rates of economic development. Yet thinking about sustainability is present in Botswana water policy mostly only in rhetoric. A series of cultural traditions and political constraints, coupled with bureaucratic managerial weaknesses, serve to maintain a system of water allocation that is unsustainable in the long run and inefficient in the short-term. Unless sustainable water use patterns are adopted, the results for the short-term, as well as the long-term, will be devastating. Drawing on data obtained through a series of interviews with government officials, leaders of non-governmental organizations (NGOs), and water resource researchers, this paper explores water policy in Botswana within the larger context of sustainable natural resource management practice and the pressures of economic development. This research was partially funded under U.S. Department of State, College and University Affiliations Grant # ASCS-1095.  相似文献

本文采用多层次转型理论的分析框架,回顾了国内外延伸生产者责任(EPR)制度的理论和实践进展,对比了EPR制度倡导者最初提出的创新导向的制度设计,与当前各国实践中基于成本—效益平衡所开展的政策评估研究,指出两者在是否应该将激进的可持续转型作为EPR基本政策目标上观点不同,其原因在于政策的技术创新激励效果难以通过可测量的政策评估方法进行有效考察,由此造成两者在EPR政策调整方向上的分歧:前者坚持EPR制度设计应该进一步完善个体责任原则,以激励生产者创新和采纳绿色技术,推进生产消费模式的系统转型;而后者则强调在现有管制框架下简化制度设计,重点完善循环处理基础设施及其管理效率。这种分歧不仅影响到发达国家EPR制度的演化,也深刻影响了发展中国家EPR制度的移植和建构。结论以中国电子废物管理实践为例,提出构建包含三个层次的演化经济学分析框架,考察EPR制度建构过程中,微观层次的企业技术选择,中观层次的供应链治理结构变动,和宏观层次的再生资源产业转型,以系统考察制度发展对技术创新的激励效果。  相似文献

For decades, large reservoirs have been built for hydropower plants in Brazil’s São Francisco River Basin. Rural development has been a simultaneous goal with a primary focus on irrigation. Irrigated agriculture, however, has suffered from poor soils, insufficient water management strategies, and a disregard for integrating grazing-based smallholdings outside of the irrigation schemes. Recurrent droughts are distressing all sectors. This synthesis assessed sustainable land management options by investigating the aquatic and terrestrial land use systems alongside their underlying ecosystem functions and services. Decisions about the allocation of scarce water proved to be both the major issue of land use discourses and driver of practices. The primarily hydroelectricity-focused water management practice cannot be maintained at the same level in the long run, as it has become ever more adverse towards competing water usages. The increasing use of the water and adjacent land also constitutes a major potential threat to water quality. Managed water level fluctuations should generally mimic natural patterns. Wind and solar power generation are suitable complements to agricultural land use. Cycling scarce nutrients between aquatic and terrestrial sectors is ambitious but promising, ultimately improving the generally poor soils in the area. Smart management of biodiversity can foster intensively-irrigated cropping, although the non-irrigated Caatinga ecosystem needs better management of its conflicting uses. Aims and responsibilities of multi-level planning and management require clarification and coordination between sectors, while practices of public participation should be revised in order to better support a comprehensive and transparent transition towards sustainability.  相似文献

变革中的中国水资源管理   总被引:2,自引:0,他引:2  
水资源短缺是世界面临的共同危机,是制约国民经济健康稳定发展的重要“瓶颈”,水资源的可持续利用已经成为经济社会可持续发展的基础性、战略性问题.缓解水资源供需矛盾的关键是加强水资源的管理.文章回顾了中国水资源管理制度的发展演变历程:只管工程的非正式水资源管理、行政命令为主的正式制度萌芽、取水许可管理和基于水权的正规制度管理等四个阶段.尽管在确立以流域管理和区域管理相结合的综合管理体制,建立以水量分配、取水许可、水资源论证为主要内容的水权管理制度和以全成本核算为原则的水价管理制度等方面成绩显著,水资源管理中仍存在水资源权属不清、水环境权得不到保障等问题.今后中国水资源改革,首先应继续深化水权改革,推动水权明晰化,建立水权交易制度;其次,健全水环境权的法律法制规范,提供相关的法律保障;最后,完善部门间的合作协调机制,真正实现对水的协同管理.  相似文献

水污染突发事件:演化模型与应急管理   总被引:2,自引:0,他引:2  
概述了突发事件演化研究的现状,总结了现阶段中国水污染突发事件的典型案例,研究了事件的演化过程,提出把社会因素和全过程干预作为水污染突发事件演化动因的一个重要方面,并在此基础上分析了水污染突发事件演化的主要动力因素,运用灾害学、应急管理、环境科学等相关理论构建了事件演化的动力因素体系,最后从系统分析的角度构建了水污染突发事件演化模型。研究表明:社会因素和应急干预对水污染突发事件的演化具有推动作用;事件演化具有阶段性,不同阶段的动力因素存在差异;水污染突发事件应急管理具有多目标性,单一目标应急管理不能有效控制水污染突发事件演化。研究水污染突发事件演化机理可为政府有效地预警与事件初期的应急决策提供重要的理论依据。  相似文献

Primary purposes for catchment management are to establish a cost-effective allocation and use of its water resources and to most effectively apply measures to protect the quantity and quality of the water produced by the catchment. For the latter purpose, diffuse sources of contamination are the greatest difficulty. Diffuse (or non-point source) water pollution poses challenges for public policy and requires innovative management approaches. Solutions ultimately require behavioural change and a broad societal response, and must be flexible and adaptive to stochastic catchment conditions and to long-term trends. Internationally, new models of governance for difficult land and water resource management problems are developing. This paper reviews the characteristics of ‘wicked’ environmental management problems and the specific policy challenges posed by diffuse water pollution. A framework for action is derived and compared to the activities and outcomes of water protection in the New York City watershed. Successes to date in this case indicate that because land management and diffuse sources of pollution have a local basis, protection of water at source necessitates the fostering of local instruments for an adaptive and twin-track strategy of applied research and stakeholder deliberation, supported by multi-level partnerships and an enabling regulatory environment. Although long running, evidence from this case alone is insufficient to establish whether potential trade-offs between water protection and the economic vitality of catchment communities can be fully resolved.  相似文献

Environmental management of pesticidal POPs in China: past, present and future   总被引:11,自引:0,他引:11  
China, the largest developing country in the world, has been undergoing rapid economic growth in the past two decades. Synchronously, large quantities of persistent organic chlorinated pesticides have been used in agriculture and non-agriculture areas. Accompanying with incomplete management framework, the improper use and disposal of pesticides have caused serious pollution problems. In this study, we discussed: (1) ten persistent organochlorine pesticides in terms of historical production, consumption and number of manufacturers, import and export; (2) the current management framework of pesticidal persistent organic pollutants (POPs) with respect to legal system and government administrative system; (3) the existing problems in the management of pesticidal POPs; and proposed recommendations for countermeasures. Based on the available information, it can be concluded that records on the historical production and consumption quantities of pesticidal POPs are incomplete which makes a difficulty in the management. Although China has come a long way in developing a modern legal system, the current system is still considered weak and inefficient; and many challenges are ahead. The government administrative system has also been reformed and improved, but over-lapping jurisdictions still exist and are ineffective in managing pesticidal POPs program. To address these existing problems in pesticidal POPs management, it was suggested that more investigations should be conducted to collect information on pollution sources of pesticidal POPs, to evaluate their environmental risks, to identify new alternative chemicals and to complete management framework of pesticidal POPs in China. Furthermore, the public should be encouraged to participate in managing hazardous pesticidal POPs in China, and international cooperation and communication should be established and strengthened imperatively as well.  相似文献

Water sector reforms in Ghana and in other developing countries resulted in the adoption of the community management approach for water systems in an effort to ensure better management and service delivery. However, community management is also plagued internal differences, paucity of technical skills, and insufficient management experience. This article presents a case study of a successful community management system in Ghana that utilized a two-phase comanagement period before a full transfer of management responsibilities to the four communities. The first phase of 3 months was a more intensive comanagement system under which the communities teamed up with public agencies and a private firm to manage the water system. This enabled the communities to acquire hands-on management experience and also tap needed skills from external agencies before a second phase of 3 months characterized by gradual withdrawal of private agency support, and a simultaneous measured assumption of higher responsibilities by the communities. Communities thereafter assumed full management responsibility of the water system and have since then posted significant successes in financial management and operations of the system such that some profits have been generated, there is regular water supply and the system operates without major technical hitches. This strategy illustrates the fact that successful community management system is possible if local capacity is adequately strengthened with external support prior to assumption of full community control of water supply systems, and if assumption of responsibilities is pursued gradually.  相似文献
