Some happy,others sad: exploring environmental justice in solid waste management in Kinshasa,The Democratic Republic of Congo

This paper explores the concept of environmental justice (EJ) in solid waste management (SWM) in Kinshasa, the Democratic Republic of Congo (DRC). It evaluates the extent to which EJ occurs in SWM and discusses the factors accounting for this state of affairs. The paper examines the relevant theoretical framework(s) and mechanisms that would facilitate the attainment of EJ in Kinshasa. It is argued that solid waste (SW) often ends up in the poorest and least powerful communities in the cities of the DRC. A qualitative research methodology, which includes exhaustive critical review of the literature, system analysis, reflections from best practices through case studies and discussion with stakeholders, was used for this study. Findings revealed that SWM in Kinshasa is a duty entrusted to publicly-funded municipal authorities. There are evidences of a clear divide between the rich and poor neighbourhoods in the manner SW is managed. This is an inequality that has only recently begun to be recognised as injustice practices in SWM. It is argued that a politico-cultural mechanism on remedying SWM inequities could enable changes that will address EJ in Kinshasa. Such a solution will go directly against the prevailing notion “some happy, others sad”.     

基于生态位理论的京津冀城市生态文明评价

生态文明评价体系是明确生态文明建设现状、定位生态文明建设存在问题的关键。从城市群视角出发引入生态位理论,界定生态文明位内涵,构建涵盖社会子系统生态位—经济子系统生态位—资源环境子系统生态位共29项指标的城市生态文明评价指标体系,并提出相对生态文明位和生态经济指数的二维模型,测算京津冀城市群6个案例城市在2007—2011年的生态文明建设水平、趋势以及地位。结果显示,2011年北京生态文明水平(相对生态文明位)最高,邢台生态文明水平最低,石家庄、秦皇岛、承德、天津生态文明水平分别排名第2、第3、第4、第5。2007—2011年,北京、承德、邢台生态文明水平呈现波动下降趋势,而秦皇岛、石家庄、天津呈现小幅上升趋势;但生态经济指数测算显示,北京的经济社会发展对于生态资源环境的占用消耗大,承德有较好的经济发展潜力。并基于该二维模型,将京津冀城市生态文明建设分为4种类型:发展失衡型、相对和谐型、高质量发展型、资源环境优势型,分别确定城市生态文明建设重点,为京津冀协同发展提供了指导依据。

The science of corporate social responsibility (CSR): Contamination and conflict in a mining project in the southern Ecuadorian Andes

In this article, I explain the role that scientific studies play in shaping collaboration and conflict over mining exploration in the Ecuadorian highlands. Toronto-based IAMGOLD conducted water quality studies to simultaneously fulfill legal obligations and secure support for drilling in an environmentally sensitive zone. With these studies, IAMGOLD generated collaborative relations with local authorities and university scientists. However, water quality studies were also used by dairy farmers to establish new connections for an opposition movement. The scientific studies enabled IAMGOLD and the dairy farmers to make competing claims about the responsibility for contamination of an important watershed. This article analyzes the conflict that resulted and challenges conventional wisdom that distinguishes a corporation's legal obligations from its voluntary CSR programs.     

Effects of economic growth on biodiversity in the United States

For many citizens and policymakers, the empirical relationship between economic growth and biodiversity conservation has not been sufficiently established for purposes of identifying the types of economic policies amenable to biodiversity conservation. Some think economic growth conflicts with biodiversity conservation; others think economic growth conduces biodiversity conservation. With panel data from 1997‐2011, encompassing US continental states, we developed a series of statistical models to investigate the relationships among species endangerment, human population, and economic growth as indicated by GDP and per capita GDP. Species endangerment is highly correlated with population and GDP, and per capita GDP is a significant regressor of species endangerment. Across US continental states, competitive exclusion of non‐human species occurs via human economic growth and population growth.     

甘肃省第三产业对经济增长贡献的实证研究

第三产业的加快发展是生产力提高和社会进步的必然结果。大力发展第三产业有利于提高工农业生产的社会化和专业化水平,有利于优化生产结构,促进市场充分发育,缓解就业压力,从而促进整个经济持续、快速和健康发展。利用1991-2009年数据,以向量自回归模型为基础,采用单位根检验、协整分析和格兰杰因果检验等方法对甘肃省第三产业与经济增长之间的关系进行了实证研究。结果表明,1991-2009年甘肃省第三产业总值对GDP的长期弹性为0．35035,第三产业对经济增长具有积极的促进作用。     

村镇供水管网优化设计探讨

如何合理确定村镇供水管网敷设方案,关系到整个供水系统的安全性和可靠性。通过生成树变化法,将环状管网转化成树状管网,确定供水管网中最短供水路线,再计算最短供水路线下的最低综合费用、供水系统的经济管径,以确定最优管道敷设方案。根据该方法对四川省某镇供水系统进行了设计。     

基于资源禀赋特征的怒江流域高山峡谷区经济发展策略思考

怒江流域高山峡谷区域具有集边疆、山区、民族、贫困为一体的特征,是我国典型的欠发达地区.尽管目前怒江流域已经进入工业化初期的经济发展阶段,但是长期闭塞、贫困和工业基础薄弱使流域经济发展动力不足.怒江流域的发展要把握云南建设面向东南亚、南亚开放的重要桥头堡这一战略机遇,立足自身的资源优势,引进外界资本与技术,打造水能资源经济,培育生态服务产业,同时通过交通基础设施建设和人力资本的培育改善发展环境.
