This paper examines how strategic environmental assessment has been practiced at the national level in China through 2005 and why it has been practiced in the manner observed. Based on literature reviews and interviews carried out in 2005 and 2006, we find that bureaucratic politics between environmental and nonenvironmental ministries has limited the legislation and implementation of strategic environmental assessment to environmental assessment (EA) for a set of government plans defined in the 2003 Environmental Impact Assessment Law. Interviewees from environmental and nonenvironmental ministries and key research institutes have reported that few planning EAs have been performed at the sectoral level. Nonenvironmental ministries have either evaded the 2003 Environmental Impact Assessment Law and have not undertaken required planning EA or have organized planning EA on their own without participation by the State Environmental Protection Administration. The rising tension between the environmental and nonenvironmental ministries has limited the role of planning EA as a participatory decision-making tool. In addition to bureaucratic politics, we find that weak public participation and underemphasis on social analysis in planning EA may have further compromised the utility of planning EA.  相似文献

This paper studies the stockpiling issue for an oil importing country that is likely to suffer embargoes, the occurrence and duration of which are uncertain. I show the existence of a decreasing reserves path that the country wants to attain in order to hedge against these disruptions. Allowing the importing country to invest in R&D in order to free itself from the embargo threat, I determine the optimal effort that should be engaged in research. The incentive to develop a backstop is shown to increase with the depletion of the reserves.  相似文献

Agricultural producer participation and spatial coordination of land use decisions are key components for enhancing the effective delivery of ecosystem services from private land. However, inducing participation in Payment for Ecosystem Services schemes for coordinating land management choices is challenging from a policy design perspective owing to transaction costs associated with participation. This paper employs a laboratory experiment to investigate the impact of such costs on participation and land use in the context of an Agglomeration Bonus (AB) scheme. The AB creates a coordination game with multiple Nash equilibria related to alternative spatially-coordinated land use patterns. The experiment varies transaction costs between two levels (high and low), which affects the risks and payoffs of coordinating on the different equilibria. Additionally, an option to communicate is implemented between neighbors arranged on a local network to facilitate spatial coordination. Results indicate a significant difference in participation and performance under high and low transaction costs, with lower uptake and performance when transaction costs are high. These effects are, however, impacted by transaction costs faced in the past. Communication improves both AB participation rates and performance with the effect being greater for participants facing high transaction costs.  相似文献

The OECD area is a major consumer and importer of strategic metals. Assurance of a steady supply of these critical materials at reasonably stable prices has for a long time been an important policy issue in the industrialized market economies. The present study addresses one aspect of supply security. The purpose is to explore the prospects for and strength of price-raising cartel action in selected strategic metal markets, mounted by producers outside the OECD countries.  相似文献

Strategic environmental assessment (SEA) is gaining widespread recognition as a tool for integrating environmental considerations in policy, plan, and program development and decision-making. Notwithstanding the potential of SEA to improve higher-order decision processes, there has been very little attention given to integrating SEA with industry planning practices. As a result, the benefits of SEA have yet to be fully realized among industrial proponents. That said, SEA practice is ongoing, albeit informally and often under a different label, and is proving to be a valuable tool for industry planning and decision-making. Based on a case study of the Pasquai-Porcupine forest management plan in Saskatchewan, Canada, this paper illustrates how an integrated approach to SEA can contribute to industry environmental decision-making and can enhance the quality and deliverability of industry plans.  相似文献

The fire simulation processes of the National Fire Management System's (NFMAS) Initial Attack Analysis (IAA) processor were evaluated by conducting two types of sensitivity analysis: one based on a hypothetical set of data to assess IAA's outputs under a wide range of fire input values, and the other using an actual Stanislaus National Forest database to test IAA's validity with a real set of data. The results revealed that IAA's outputs (projected annual number of fires and area burned) were most sensitive, in descending order, to the input values of the fire spread rate, the productivity rates of the suppression forces, and the initial attack time, for all fuel models tested. In contrast, IAA's outputs were extremely insensitive to variations in the fire size at discovery. Changes are necessary in the ways IAA incorporates the fire size at discovery to facilitate the comparison among various fire detection options. The program's “escaped fire situation” analysis was found inadequate, because the projected annual frequencies and final sizes of the simulated escaped fire events produced unacceptable results with the Stanislaus National Forest database. Assigning final sizes to simulated escaped fires according to the fire intensity level in which they are historically expected to occur provides a consistent way of calculation of the projected annual area burned and the consequent cost plus net value change (C + NVC).  相似文献
