The San Francisco Bay-Delta: A failure of decision-making capacity

The paper reviews the history of Bay-Delta decision-making in California in order to highlight the continuity between what happened with CALFED and what happened in the preceding decades since water project deliveries began in 1949. Throughout this period, there has been intense conflict about whether and how to transfer water from the Bay-Delta to users elsewhere—a conflict marked by a fundamental opposition of interests among stakeholders. We document how the State of California has failed to organize itself effectively to resolve this conflict and make a decision on how to manage the Delta. The strategy consistently adopted by the State was to encourage the main parties – agricultural and urban water diverters, and fisheries and other instream-protection interests – to work out a solution among themselves, rather than imposing one externally. However, economic theory suggests that a bargaining solution is unlikely to exist because of the extreme opposition of interest among the parties. The Bay-Delta history amply confirms this theoretical prediction. Thus, the State's strategy of relying on voluntary agreement to resolve the issue is fundamentally misconceived and is, at some level, an abdication of its responsibility.

金融风暴中循环经济的一个悖论——论保护废旧物资回收利用体系政策

在华尔街金融风暴中,废旧物资回收利用链条一度陷于瘫痪,资源循环利用遭受阻断,循环经济发展受到严重影响。企业对再生资源利用选择水平与废品回收率的价格所存在的两难关系,决定了合理的价格水平和稳定的价格决定机制是关系到促进再生资源综合利用水平不断提高,循环经济顺利发展的必要条件。因此,政府需要进一步完善保护废旧物资回收利用体系政策,化解矛盾,促进循环经济发展。

政府灾害应急管理体系的国际比较研究

2008年的南方雪灾和汶川大地震凸显出我国灾害应急管理体系的严重缺陷.本文旨在比较研究美日等几个先进国家灾害应急管理系统,以期为我国灾害应急管理体系的完善提供有益的借鉴.总的来说,我国灾害处理者对灾害管理的科学认识还不够,灾害法律法规体系和组织机构也不完善,救灾体系中存在着大量的非救灾人员和非专业救灾设备.针对以上问题,本文认为我国应尽快完善救灾应急管理系统的法律法规,促进我国救灾组织机构和以及设立培训机构以培养优秀的专业救灾队伍.

安全伦理与安全生产——解析安全伦理命题,制定“道德的”安全生产激励政策

从分析社会发展对安全伦理命题的关注和中国安全生产问题所引发的道德问题入手,指明安全伦理命题对社会经济政治发展的正面作用;依据道德选择和道德评价时所诉诸的安全伦理原则,区分"道德的"和"不道德的"两种安全生产伦理范式,并在该基础上提出一个制定"道德的"安全生产激励政策的选择方案:建立国家工业事故预防的伦理战略和伦理指导制度;制定"公平的"、"合理的"安全资源分配政策;制定中小企业的"道德的"安全生产管理战略;建立安全活动领域的防腐败机制,维护社会正义;从"人权"道德规范出发,创立新的安全生产规范。     

Hydrogen and transportation: alternative scenarios

If hydrogen (H₂) is to significantly reduce greenhouse gas emissions and oil use, it needs to displace conventional transport fuels and be produced in ways that do not generate significant greenhouse gas emissions. This paper analyses alternative ways H₂ can be produced, transported and used to achieve these goals. Several H₂ scenarios are developed and compared to each other. In addition, other technology options to achieve these goals are analyzed. A full fuel cycle analysis is used to compare the energy use and carbon (C) emissions of different fuel and vehicle strategies. Fuel and vehicle costs are presented as well as cost-effectiveness estimates. Lowest hydrogen fuel costs are achieved using fossil fuels with carbon capture and storage. The fuel supply cost for a H₂ fuel cell car would be close to those for an advanced gasoline car, once a large-scale supply system has been established. Biomass, wind, nuclear and solar sources are estimated to be considerably more expensive. However fuel cells cost much more than combustion engines. When vehicle costs are considered, climate policy incentives are probably insufficient to achieve a switch to H₂. The carbon dioxide (CO₂) mitigation cost would amount to several hundred US$ per ton of CO₂. Energy security goals and the eventual need to stabilize greenhouse gas concentrations could be sufficient. Nonetheless, substantial development of related technologies, such as C capture and storage will be needed. Significant H₂ use will also require substantial market intervention during a transition period when there are too few vehicles to motivate widely available H₂ refueling.
