对我国水患防治的战略思考 总被引:1,自引:0,他引:1
1998年的大洪水,为中国人敲响了警钟,使人们认识到,对我国的水患防治,必须从战略上去思考,要重新规划蓝图,尽快采取切实的战略步骤,从根本上解决困扰我国的洪灾问题。首先,要争取在最短的时间内形成全国范围的水患防治工程体系,以抵御未来大洪水对我们的侵害。而这仅仅是“亡羊补牢”之举,更重要的是,要反思我们的行为,在思想上回归自然,那就是遵循自然生态规律,在行动上恢复生态平衡,不能再干自掘坟墓,自毁家园的蠢事。为此,我认为,应从以下几个方面去做:一、封山育林,植树造林,保护森林资两据报导,长江流域的森林采… 相似文献

Debate on the economic valuation of the countryside is typically polarized between absolutist critics who would deny it any valid role and equally fervid proponents who see its techniques as the only way of integrating the environment into policy making. Such debate is structured by conflicting notions of rights, responsibilities and values, rather than by consideration of the role of technique in practical policy‐making. This paper attempts to take the debate forward and begins by examining the ways in which rights, responsibilities and values have been historically created. The techniques of economic valuation rest on particular conceptions of these, making them irreducibly political, and at the same time their results are often used to justify political decisions. Yet the proper role of technique ought to be to explore options. Provided that the sort of clarification that economic valuation offers is understood, it may, along with other types of technique, be used to open up the decision making process. 相似文献

Federal land managers are faced with the task of balancing multiple uses and goals when making decisions about land use and
the activities that occur on public lands. Though climate change is now well recognized by federal agencies and their local
land and resource managers, it is not yet clear how issues related to climate change will be incorporated into on-the-ground
decision making within the framework of multiple use objectives. We conducted a case study of a federal land management agency
field office, the San Juan Public Lands Center in Durango, CO, U.S.A., to understand from their perspective how decisions
are currently made, and how climate change and carbon management are being factored into decision making. We evaluated three
major management sectors in which climate change or carbon management may intersect other use goals: forests, biofuels, and
grazing. While land managers are aware of climate change and eager to understand more about how it might affect land resources,
the incorporation of climate change considerations into everyday decision making is currently quite limited. Climate change
is therefore on the radar screen, but remains a lower priority than other issues. To assist the office in making decisions
that are based on sound scientific information, further research is needed into how management activities influence carbon
storage and resilience of the landscape under climate change. 相似文献

Collaborative policy making has become increasingly significant in environmental management, but it is often evaluated by whether or not agreement is reached and implemented. The most important outcomes of such policy dialogues are often invisible or undervalued when seen through the lens of a traditional, modernist paradigm of government and accountability. These dialogues represent a new paradigm of governance that can be best understood in the light of a complex adaptive system model of society. From this perspective collaborative policy making is a way of making a system more flexible, adaptive and intelligent. The authors document such outcomes in three cases of water policy making in California, including the San Francisco Estuary Project, the CALFED Bay-Delta Program and the Sacramento Area Water Forum. The outcomes include social and political capital, agreed-on information, the end of stalemates, high-quality agreements, learning and change, innovation and new practices involving networks and flexibility. 相似文献

Environmental management decisions typically lie at the interface of science and public policy. Consequently, these decisions involve a number of stakeholders with competing agendas and vested interests in the ultimate decision. In such cases, it is appropriate to adopt formal methods for consensus building to ensure transparent and repeatable decisions. In this paper, we use an environmental management case study to demonstrate the utility of a mathematical consensus convergence model in aggregating values (or weights) across groups. Consensus models are applicable when all parties agree to negotiate in order to resolve conflict. The advantage of this method is that it does not require that all members of the group reach agreement, often an impossible task in group decision making. Instead, it uses philosophical foundations in consensus building to aggregate group members' values in a way that guarantees convergence towards a single consensual value that summarizes the group position. We highlight current problems with ad hoc consensus and negotiation methods, provide justification for the adoption of formal consensus convergence models and compare the consensus convergence model with currently used methods for aggregating values across a group in a decision making context. The model provides a simple and transparent decision support tool for group decision making that is straightforward to implement. 相似文献

The paper examines alternative roles for planners in planning for sustainable development. First, it outlines the particular context of the task focusing on operational questions, critical issues and sustainable development planning principles. It then explores roles for planners in this context distinguishing broadly among technician, politician and hybrid planners. It evaluates broadly each role's effectiveness and challenges, in particular decision making and political contexts. Finally, it discusses, first, the implications of these roles for planning education and identifies the main groups of skills planning schools should offer. Second, it analyses briefly the implications of these roles for planning practice in terms of the spatial/organizational level of planning, time horizon, functional planning areas, political/decision making system and planning's position in this system. 相似文献

Environmental Impact Assessment (EIA) was developed and introduced in the 1960s during a time that was dominated by three key societal influences. These were the growth of modern environmental concern, the drive for more rational, scientific and objective environmental decision making and a desire for more public involvement in environmental decision making. The legitimacy of EIA, as a tool to aid decision making, lies in its ability to meet the requirements of all three demands, the chief among these being its ability to be a systematic scientific and rational approach to decision making. Yet today we live in a society that no longer accepts the rationalist model as either possible or desirable. The deference to ‘the expert’ and our trust in science and technology has steadily declined during the period of EIAs development and widespread use. Today, EIA still depends for its legitimacy on its claim to provide a systematic and scientific approach to assessments, while society has moved on. This paper examines this growing divergence and argues that it is time for a major re‐evaluation of the role of EIA in environmental decision making. 相似文献
