Dynamics and Causation of Environmental Equity, Locally Unwanted Land Uses, and Neighborhood Changes

/ Why are some environmental risks distributed disproportionately in the neighborhoods of the minorities and the poor? A hypothesis was proposed in a recent study that market dynamics contributed to the current environmental inequity. That is, locally unwanted land uses (LULUs) make the host communities home to more poor people and people of color. This hypothesis was allegedly supported by a Houston case study, whereby its author analyzed the postsiting changes of the socioeconomic characteristics of the neighborhoods surrounding solid waste facilities. I argue that such an analysis of postsiting changes alone is insufficient to test the causation hypothesis. Instead, I propose a conceptual framework for analysis of environmental equity dynamics and causation. I suggest that the presiting neighborhood dynamics and the characteristics of control neighborhoods be analyzed as the first test for the causation hypothesis. Furthermore, I present theories of neighborhood change and then examine alternative hypotheses that these theories offer for explaining neighborhood changes and for the roles of LULUs in neighborhood changes. These alternative hypotheses should be examined when analyzing the relationship between LULUs and neighborhood changes in a metropolitan area. Using this framework of analysis, I revisited the Houston case. First, I found no evidence that provided support for the hypothesis that the presence of LULUs made the neighborhoods home to more blacks and poor people, contrary to the conclusion made by the previous study. Second, I examined alternative hypotheses for explaining neighborhood changes-invasion-succession, other push forces, and neighborhood life-cycle; the former two might offer better explanation.KEY WORDS: Environmental equity and justice; Locally unwanted lane uses; Siting; Market dynamics; Invasion-succession; Neighborhood changes     

长江经济带水质目标管理平台总体设计

为强化长江经济带资源整合与共享,集成统一规范的大数据平台,基于“十一五”“十二五”国家水体污染控制与治理科技重大专项数据和模型库资源,以面向服务的架构(SOA)和模块化设计为支撑,遵循“五横两纵四统一”的平台架构设计思路,应用大数据挖掘、云计算等现代信息技术,构建长江经济带水质目标管理平台.平台基于长江经济带水生态环境功能分区,兼顾不同类别水质目标管理技术的协调性、衔接性和适应性,对水质目标管理相关信息进行跟踪、模拟、分析和三维可视化表达,在水生态环境功能分区管理、数据汇交与信息共享、容量总量管理、风险评估与预警等方面实现业务化运行,实现全景式水质达标形势研判、一体化风险联防联控.平台已在国家长江生态环境保护修复联合研究中心进行业务化运行,将有效提升长江经济带水环境综合管理能力,同时可为其他重要流域水质目标管理提供信息化工作参考.

加强松花江上游石油开发的预警研究

松花江上的石油开发对松花江和哈尔滨市饮用水源地的潜在污染危害已引起政府部门的重视.松花江上石油开发中一旦出现事故其污染所造成突发事故将是十分严重的.应加强松花江上石油开发的预警研究.并对松花江上的石油开发现状、存在的问题和隐患进行深入调查研究.对江上已开发和在建油田制定出相应对策,确保松花江水质安全和哈尔滨市饮用水源地的水质安全.     

Residents' preparedness and response to the Kalamazoo Tornado

A survey was conducted of individuals residing directly in the path of the tornado that hit Kalamazoo, Michigan, on 13th May 1980. The residents' tornado preparedness and response were examined in an effort to evaluate the city's emergency warning system. The system was adequate for people on the east side of the city and lacking for west side residents. Other factors pertaining to the storm event and human response were also evaluated.
