Environmental health, development and economic empowerment of rural women in Nigeria

Sustainable development is a process that has social, cultural, economic and ecological dimensions. The necessity of improving the quality of life of rural women in terms of socio-economic aspects in developing countries like Nigeria is the aim of this study. The study was carried out in four villages of Tonkere district (Okeake, Abagboro, Elefon and Akiri), situated on expansive university land at Ile-Ife and typical of rural settings in Nigeria. Data were generated from group meetings, local government and individual interviews and surveys. In rural Nigeria, women’s essential contributions to overall environmental health, development and economy are negatively influenced by domestic tasks such as gathering of fuel woods and biomass for cooking. In reality, wood burning, kerosene stoves, and open fireplaces emit significant quantities of known health-damaging pollutants. The significant emissions of health-damaging pollutants per unit activity, combined with daily use in close proximity to rural human populations mean household biomass fuel use exposes total population to important pollutants resulting in ill-health and premature dead. Application of solar energy collectors and hosts of solar devices is an alternative energy sources in rural areas that could best improve women’s health, socially and economically, and positively add to ecological dimensions.

Neighbourhood perceptions among inner-city adolescents: Relationships with their individual characteristics and with independently assessed neighbourhood conditions

We investigated relationships between adolescents’ perceptions of their neighbourhood, their mental health and independently assessed indicators of conditions in their residential neighbourhood. The Research with East London Adolescents Community Health Survey (RELACHS) provided information for 2370 adolescents on area perceptions (specifically alienation from/attachment to the area and satisfaction/dissatisfaction with local amenities and services), and on individual and family attributes including mental distress (measured by the Strengths and Difficulties Questionnaire). These were combined for this study with independently assessed small area geographical indicators proposed by government to measure local deprivation in England. A Bayesian regression analysis using Gibbs sampling investigated associations between the predictor variables and neighbourhood perception. Alienation from neighbourhood and dissatisfaction with local amenities was greater for girls than for boys and for the older adolescents sampled. Those of ‘Asian’ or ‘Black’ ethnicity, from relatively harmonious families, or with higher levels of social support were less likely to express negative area perceptions. While previously published research found no significant direct association between mental health and small area indicators, this analysis suggests that those with relatively high levels of distress did have worse area perceptions. Also, certain independently assessed area indicators were associated with adolescents’ views of their neighbourhood.     

Modeling a wetland system: The case of Keoladeo National Park (KNP), India

A model for the wetland part of KNP is presented and analyzed. Two-dimensional parameter scans suggest that this minimal model possesses dynamical complexities. Per capita availability of water to “bad” biomass (W₁) is one of the most vital parameters. One can ensure good health of the park by restricting the par capita availability of water to low values. Getting the “bad” biomass removed by granting permits to villagers should go hand in hand with water management and conservation activities. The model presented in this paper may be helpful in designing the timing and nature of human interventions in the form of implementation of well worked out policies in future.     

水资源与产业结构高级化的适配度时空差异及动态演变

面向“以水定产”的水资源管理新要求,明晰水资源与产业结构高级化的适配情况具有客观需求。针对现有方法在代数式表达和经济学解释上的不足,立足弹性,构建二者的适配度测算指标;并结合Dagum基尼系数和Kernel密度估计,揭示区域及其子地区适配度变化的时空差异特征、贡献率及动态演变规律。以长江经济带为例研究得知：要理性看待产业结构高级化对水资源高效利用的促进作用;经济带阶段性地向适配度更高的方向演变,上中下游地区内及之间适配度的时空差异是经济带时空差异的主要来源,上下游地区内依然存在适配度不均衡问题,据此提出促进水资源高效利用的建议。此外,需结合工业发展阶段,辨别因工业发展相对滞后而引发的“虚强适配”问题。     

Coming to grips with scientific ignorance in the governance of endocrine disrupting chemicals and nanoparticles

New technologies are characterized by various forms of incertitude that challenge both scientific expertise and regulatory action. In this paper, we argue that these incertitudes place experts in irreducible double bind situations, which may end in paralysis. Double binds emerge when primary injunctions are contradicted by secondary injunctions at a different logical level, which affects the interpretation of the primary injunction. Adequately addressing the challenges posed by new technologies requires phronesis, or pragmatic, context-dependent and action-oriented knowledge grounded in value deliberation. Using endocrine disruptors and carbon nanotubes as empirical examples, we argue that in relation to new technologies involving various kinds of incertitude, being phronimos—the person who can do phronesis—involves synthetically and simultaneously enacting parts of the three interrelated domains of knowledge, ethics and institutions, also across different logical levels. The special kind of experience-based phronesic skill that required in the regulatory appraisal of new technologies is thus fundamentally related to the human capacity of pattern recognition. Finally, we argue that being aware of and making full use of practical wisdom thus conceptualized enables a new operationalization of the precautionary principle.

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.     

天津滨海新区生态系统服务评估及空间分级

采用提出的“功能当量”相对评估模型,并以RS和GIS为技术平台对2009年天津滨海新区生态系统服务功能进行评估,采用区域网格化空间表达,对研究区进行分级研究.结果表明,滨海新区生态系统单位面积服务功能当量大小依次为湿地、水体、林地、草地、耕地、裸地;2009年滨海新区生态系统服务功能当量总和为1068680.13,III级以上功能当量的单元格比例为71.22%,总体处于较高水平;通过与价值量法结果对比,得出利用“功能当量”相对评估模型对研究区的评估结果与价值量法的评估结果具有显著相关性,证明该评估模型的可行性和合理性.
