Efficient and Practical Approaches to Ground‐Water Right Transfers Under the Prior Appropriation Doctrine and the Snake River Example1

Abstract: Water right transfers are one of the basic means of implementing changes in water use in the highly appropriated water resource systems of the western United States. Many of these systems are governed by the Prior Appropriation Doctrine, which was not originally intended for application to ground‐water pumping and the conjunctive management of ground water and surface water, and thus creates an administrative challenge. That challenge results from the fact that ground‐water pumping can affect all interconnected surface‐water bodies and the effects may be immeasurably small relative to surface water discharge and greatly attenuated in time. Although we may have the ability to calculate the effects of ground‐water pumping and transfers of pumping location on surface‐water bodies, mitigating for all the impacts of each individual transfer is sufficiently inefficient that it impedes the transfer process, frustrates water users, and consequently inhibits economic development. A more holistic approach to ground‐water right transfers, such as a ground‐water accounting or banking scheme, may adequately control transfer third‐party effects while reducing mitigation requirements on individual transfers. Acceptance of an accounting scheme can accelerate the transfer process, and possibly reduce the administrative burden.     

Comparison of China’s Environmental Impact Assessment (EIA) Law with the European Union (EU) EIA Directive

In this paper, we first review the development of China’s Environmental Impact Assessment (EIA) system in the past 30 years. Then we compare the framework and operational procedures of China’s new EIA law with those of the EU EIA Directive. We also compare public participation, as well as sanctions and control in the two EIA systems. In addition, we identify where the processes in both EIA systems are similar or different from one another. By comparison, we noted that there are at least three obvious weaknesses in China’s EIA system: (1) the application of new models for EIA legislation; (2) the improvement of EIA guidance and education; and (3) the enhancement of public participation in EIA process. Our study indicates that these three major shortcomings should be overcome and improved in China’s EIA system, when compared with the EU EIA system.     

化学需氧量在造纸废水中分布规律及采样点位的优化

目前对造纸废水的监测通常采取随机取样,很少考虑污染物在废水中的分布情况,所以取得的样品很难反映污染物的实际排放情况。为此,通过对某造纸厂排废废水中化学需氧量分布夫妻及采样点位的优化研究。     

Awareness of environmental legislation as a deterrent for wildlife crime: A case with Masaai pastoralists,poison use and the Kenya Wildlife Act

Illegal wildlife crime is a global phenomenon, accelerating the ongoing biodiversity crisis. In the Old World, and particularly in Africa, illegal use of poisons to eliminate carnivores is the main driver of the continental vulture crisis. Knowledge about the underlying source and drivers of this threat is lacking for most areas, including Kenya, a global vulture and biodiversity hotspot. An extensive questionnaire survey of over 1300 respondents was run, using a specialized questioning technique and quantitative analytical approaches. Results show that, while pastoralists have a positive attitude towards vultures, over 20% of them use poisons to eliminate predators. Poisoning was largely driven by livestock losses to predators, and by negative attitude towards predators. Poisoning was less prevalent among respondents aware of the Kenya Wildlife Act. Overall, we suggest that a combination of top-down, e.g. legislation, and bottom-up (such as corrals or compensation) along with awareness campaigns may help reduce poisoning on the ground.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01695-8.     

考虑气液置换的压回法气井压井过程对井底压力的影响

为在压回法气井压井计算中进一步贴合现场实际情况,提出新的压回法气井压井过程计算方法.在压井过程中,考虑压井液与侵入井筒的气体发生置换,导致井筒流体自上而下分布为液-气液2相-气-气液2相的实际问题,建立压井过程模型,并对井底压力的变化进行计算分析.结果表明:发生气液置换对压回法压井过程井底压力以及注入压力具有明显影响,...     

生态环境损害惩罚性赔偿规则的检视与适用

生态环境损害的惩罚性赔偿规则首次在《民法典》侵权责任编中确立。针对这项制度创新,本文梳理了惩罚性赔偿规则在不同法律制度中适用范围和适用条件的差异性,并进一步分析惩罚性赔偿在生态环境损害救济体系中所具有的特殊规则和功能定位。在缺乏生态环境领域部门法配套的情况下,《民法典》中惩罚性赔偿规则的适用应基于生态环境的公益性而适当扩大请求权主体范围,基于严格法定性而明确举证责任负担和证明标准,基于生态环境要素的特殊性而完善多样化的赔偿内容和计算方法。

应对环境风险的反身规制研究

面对当前日益严峻的环境风险和生态危机,环境领域的两大规制模式——命令控制规制模式和激励规制模式呈现规制失灵、治理不力的困境。从反身法理论来阐释,是由于这两种规制模式忽略了法律系统与其他社会子系统自身的独特运行逻辑,法律系统具有运行的封闭性与认知的开放性,有效的规制模式必须实现不同系统之间的结构耦合。反身规制是一种对自我规制的规制,其在承认法律自身规制局限性的基础上,培育其他子系统的反思结构,为提升当前环境治理绩效提供了一个新路径。实现对环境风险的反身规制,需要从信息披露、程序设计及商谈规范方面建构相应的法律制度。
