Incentives to diffuse advanced abatement technology under environmental liability law

Polluting firms with advanced abatement technology at their disposal have incentives or disincentives to share this technology with other polluting firms. The ‘direction’ and extent of those incentives depends on the liability rule applicable and the way technical change impacts marginal abatement costs. We establish that incentives for diffusion are socially optimal under strict liability and socially suboptimal under negligence if technical change lowers marginal abatement costs for all levels of abatement. Negligence may, however, induce better diffusion incentives than strict liability if technical change decreases (increases) marginal abatement costs for low (high) levels of abatement.

ESTABLISHING WATERSHED MANAGEMENT IN LAW: NEW ZEALAND'S EXPERIENCE1

ABSTRACT: New Zealand is one of the first countries in the world to enshrine the concept of watershed management in law, through institutional arrangements and the Resource Management Act of 1991 ‐ a law constructed on a watershed management legacy begun in 1941. This paper outlines the development of New Zealand's Resource Management Act (as it applies to water management) and the lessons that have been learned in its implementation.     

黄柏河流域梯级水库沉积物磷形态特征及磷释放通量分析

为揭示黄柏河流域饮用水源水库的磷负荷特征,采用SMT分级方法对流域内3座梯级水库（玄庙观、天福庙、西北口水库）的沉积物磷形态特征及垂向变化特征进行了分析,并初步估算了沉积物-水界面正磷酸盐释放通量以及各形态磷含量对磷释放的影响.结果发现,沉积物总磷（TP）含量从流域上游至下游水库呈现递减趋势,平均值分别为（8070.0±2251.4）、（2681.2±1709.8）和（2656.6±1599.7）mg·kg^-1,均处于高度污染水平.3座水库中各个采样点磷形态之间的含量主要表现为：HCl-P > OP > NaOH-P.根据Fick第一定律,计算得到流域内3座梯级水库均表现为上覆水正磷酸盐的源,正磷酸盐释放通量从流域上游到下游水库呈现递减趋势,范围为0.0179~0.1825 mg·（m²·d）^-1.正磷酸盐释放通量与表层水体DO和叶绿素呈现正相关,与HCl-P,OP和TP同样表现为显著正相关.     

南帕斯凝析油存储挥发与安全影响分析

南帕斯凝析油产自于伊朗,在炼制过程几乎不残留油渣,因而倍受炼油企业青睐。南帕斯凝析油中硫化氢及硫醇硫等有毒气体的浓度较高,在储存过程中由于储罐呼吸现象的存在,有毒气体挥发量较大。一旦有毒气体挥发量超出《工作场所有害因素职业接触限值》中规定的限值,极容易引发安全事故。南帕斯凝析油的这一特性给企业安全工作带来了很大挑战。以分析南帕斯凝析油理化性质以及存储设备设施现状为基础,运用储罐大小呼吸计算公式定量计算出有毒气体的挥发量及在空气中的含量;并且以呼吸阀口为连续性点源建立气体扩散模型,根据高斯定律推算出下风向各点有毒气体浓度值,从而划分防护等级区域并制定相应的安全操作要求,为企业存储安全提供有效的防护方案。     

Park gazettement and integrated conservation and development as factors in community conflict at Bwindi Impenetrable Forest, Uganda

Conflicts between protected-area managers and local people are common, but the drivers of conflict are rarely analyzed. This limits opportunities to identify strategies that reduce conflict and the magnitude of resulting threats to conservation. Integrated conservation and development (ICD) was adopted at Bwindi Impenetrable Forest, Uganda, to reduce conflict during gazettement of the national park, but the success of this approach remains contested. We retrieved documents of conflict written by park staff and local people from 1986 through 2000 (before, during, and after gazettement). We extracted data on 48 incidences of violent conflict and categorized them by gazettement period, area, instigator, and type to undertake a historical analysis of the triggers of violent conflict at Bwindi. Before and during gazettement, local villagers instigated most of the conflict incidents when law-enforcement efforts sought to halt commercial activities within Bwindi. No conflict arose from the arrest of villagers collecting subsistence resources during these periods. After gazettement, prohibitions on commercial activities continued to drive conflict even though villagers collecting subsistence resources were arrested more frequently than before gazettement, and local attitudes toward the park had improved following receipt of ICD benefits. Law-enforcement efforts targeted commercial activities to reduce this threat to Bwindi's mountain gorillas (Gorilla beringei beringei), although the activities remained important income sources for people in villages near Bwindi. Losing commercial income following gazettement therefore appeared to be their primary motivation for instigating conflict with park rangers. Prohibitions on subsistence resource use triggered conflict less often. Our use of typologies for a multivariate conflict analysis demonstrates that by identifying differences between effects of conservation as drivers of conflict, conflict analysis can enable a more strategic deployment of conflict-resolution measures that could further conservation efforts. At Bwindi targeting ICD toward individuals who lost benefits from commercial activities may strengthen the role of ICD in conflict resolution and conservation.     

超深竖井掘进岩爆特征及防治措施

由于会泽矿3#超深竖井（施工深度达1 526 m）的工程地质条件,在竖井开挖到一定深度后有不同程度的岩爆现象显现,其中两次比较严重的岩爆发生的位置埋深较深,井筒深度达到1 400 m以上。为此建立了井壁地应力监测系统,对岩爆的发生进行预测。根据井壁周边不同深度布置的4个点处的应力变化曲线分析,总结了地应力分布规律,4#位置（东偏南70°）井壁受测压力最大,最大水平主应力可以达到120 MPa以上,其方位与最大主应力方向相符。结合3#竖井工程岩爆现象的分析,以及岩爆发生的特征,给出了预防岩爆所采取的工程措施,为此类工程施工制定岩爆防治措施提供了科学依据。
