The disparity in both population and wealth distribution in Nigeria by geo-political zones is well recognized. There is also the recognition that some of the environmental problems in certain sections of the country can be attributed to the imbalance in both population and wealth distribution. Hence the various agitations for environmental resource control in the country. What is lacking however is the research that shows the magnitude of the linkages between the disparity and the environmental degradation in regional context. This provides the basis for this research. To achieve the aim of the research, a STIRPAT model was employed as an analytical tool. The findings show that the southern geopolitical zones are generally more densely populated and wealthier than the northern zones. The south is also experiencing a higher degree of environmental resource degradation attributable to anthropogenic factors. Thus, there is congruence between population density, wealth distribution and environmental degradation in Nigeria. Therefore the achievement of sustainable environment and development in Nigeria requires deliberate policies to mitigate the impact of population concentration and wealth creation on the environment.

The operational designing of Environmentally Sustainable Economic Development (ESED) emerges as an urgent and demanding task. Even though ESED has paved the way for thought-provoking and constructive scientific dialogue, appeal for designing an operational ESED is still lagging behind the needs of contemporary societies, leaving much to be desired. With this in mind, the present paper will aim at delineating principles for the operational application of ESED. First, the preservation of crucial properties of environmental functions and ecosystems, emerges as a prime condition of ESED. The second condition concerns the provision of the economic process with sufficient natural inputs; in this context, the paper intends to trace certain operational tenets governing the use of natural resources. Finally, the appropriate institutional settings for the operational design of ESED are traced.

On-going population growth and resulting domestic demand for water require rapid and effective decision-making as regards groundwater management and control of the various sources of salinization and pollution in Coastal aquifers. Sustainability of water resources for utilization by future generations must therefore be a high priority, not only for the purpose of fulfilling needs for water usage but also for bringing people into harmony with their ambient natural environment.The objective of this paper is to propose an empirical approach for prioritization of the needs involved for sustainable aquifer management. The approach involves a schematic format to:(1) develop a global understanding of an aquifer's hydrological and environmental properties in order to delineate appropriate eco-hydrological scenarios and recommend corresponding operational management activities; and(2) emphasize the importance of educating and increasing the awareness of the population involved as to the need for and viability of socially acceptable measures for sustainable management of groundwater and other resources.The psychologist Abraham Maslow utilized a pyramid to illustrate that until people's most basic needs were fulfilled, higher levels of needs would remain irrelevant. This paper postulates a comparable pyramid prioritizing hydrological needs required for progressing towards sustainable groundwater resources. Two sub-regions of Israel's Coastal aquifer in the Sharon region have been presented as representative areas, each characterized by different stress of exploitation. In assessing these sub-regions situation, specific measures have been recommended for achieving and/or maintaining sustainable groundwater resources in light of the ambient environment, and the level of the population on the pyramidal hierarchy of groundwater needs.  相似文献

以基于生态系统服务的生态足迹(ESEF)为基础的水生态承载力评估方法,综合考虑了水量支撑、水质限定和水生态稳定三方面特征,从而实现了足迹方法对水生态系统承载能力的有效表征。然而,如何界定水产品、水资源和水污染足迹以及承载力之间的关系,是目前研究的重点和难点。以太湖流域上游湖州市为例,探讨了在考虑或不考虑水质标准与环境功能分类的情况下,如何利用求并集法或求平均值法进行基于ESEF的水生态承载力评估。研究表明,两种方法均反映出湖州市人们对水生态系统服务的消费需求超出了当地水生态系统的供给能力,需求与供给之间的差距对当地水生态系统的可持续性造成影响。综合考虑水产品供给、水量支撑和水质保障三方面因素,湖州市水生态系统可承载的人口与经济规模为现状水平的95%;如果增加对水质标准和环境功能分类的考虑,则湖州市水生态系统的承载能力仅为现状水平的79%。虽然求并集法的计算结果更有说服力,但是求平均值法则提供了在更小尺度上研究的可能。  相似文献

A comparative analysis of field observations and experiments on the distance and rate of dispersal of self-sown Scotch pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) progeny has shown that the rate of their hydrochorous dissemination downstream is an order of magnitude higher than the rate of dispersal in upland areas. A hypothesis assigning priority to the role of hydrochory in the expansion of conifer populations to the tundra (periglacial) zone along with climate warming has been formulated and substantiated by comparative isozyme analysis of populations in transects lying along and across rivers.  相似文献

以加入WTO为标志.中国积极参与经济全球化已成为一种必然.但由于我国的国土规模、自然环境、气候条件等方面的地区差异很大,地区之间在发展水平上一直存在着差距,地区发展不平衡是个长期的国内政治经济现象.这种地区发展的差距表现为各类地区融入经济全球化的程度不同,反应不同.有些地区能够借助经济的全球化而发展自身,有些地区则无法从中受益,甚至因而处于更加落后的境地.本文从三大经济地带、各经济区和各省(市)区三个屡次分析和探讨了不同区域对经济全球化响应的差异,并对全球化条件下我国内部区域一体化格局进行了深入的研究.  相似文献

In the crustacean Eudiaptomus gracilisSars, relationships between mortality (D) and the ratio of main cations (R, the ratio of the sum of potassium and sodium equivalent concentrations to the sum of calcium and magnesium equivalent concentrations) were studied. The calculated regression equation D= 315 – 355/Rwas used for predicting the state of E. gracilispopulation in Lake Poppalijarvi (Karelia) polluted with mining waste. At R< 0.47, the population will survive; at R> 1.53, its extinction should be expected. The results of hydrobiological observations on Lake Poppalijarvi confirmed the prognosis based on the equation.  相似文献

Studies on the distribution of the forms of heavy metals (HMs) in the humus soil horizon were performed in the Berezinskii Reserve and Braslavskie Ozera National Park. The ratios of active to inert HM forms (with trace values of the mobile form) in these areas proved to be similar and independent of the total HM content. The calculated coefficients of technogeneity (Kt and Xt) and mobility (Km and Xm) are proposed, which reflect the natural ratio between the forms of HMs in the Northern and Central lithogeochemical provinces of Belarus.  相似文献

The risk communication (RC) field is dominated by the practical and normative socio-technical aim of improving communication on risk (CR), especially from the viewpoint of regulatory agencies and government administrations. Despite some change of scope and orientation over the past 30 years, two theoretical ideas have persisted: the subjective–objective risk dichotomy and the transmission (also known as code) model of communication. This theoretical legacy makes context a blind spot in RC. The study of CR themes should consider (1) the socially constructed nature of risk and (2) communication as a situated social practice of information sharing. Results of a case study of public participation in a controversial railway tunnel project in the south of Sweden, offer lessons for future research pointing to crucial contextual dimensions of CR. It is argued that the variable ontology of risk, the constitutive nature of power relationships and the practical rationality of actors must be taken into account in research on the social CR.  相似文献

The article establishes an evaluation index system of the intensive land use from the perspective of enterprises. It is based on the questionnaire survey and evaluates the levels of the intensive use of the land in the electrical machinery and equipment manufacturing industry in Changzhou, Nantong, and Yancheng of Jiangsu Province. The evaluation result shows that there is obvious difference in the levels of the intensive use of the land in this industry in the three cities. The present article makes a detailed analysis on the causes of the difference. The analysis shows difference in results of the socio-economic and urban development stage, industrial features, population density, and technological progress. Finally, it proposes some suggestions to improve the efficiency of the industrial land use.  相似文献

作为当代环境伦理学之生态中心论的代表,克里考特以新物理学与生态学的视角引向后现代主义的整体观。这一思路指向的是整体论系统观的范式,后者具有四项特征:1整体的性质不能被还原为部分的性质;2整体是部分形成的原因与依据;3部分是系统地互相联系的;4部分是内在地互相联系的,即关系决定存在。以该整体论系统观的范式为依据,克里考特的后现代视域既涉及本体论,也指向价值论。在本体层面,克里考特借鉴了深生态学中"充分实现的自我"的概念试图解构笛卡尔的主客二分。进而,在削弱现代哲学中三类性质(数量性、质量性与价值性)区分的同时,克里考特提出了"实质价值"的概念,并试图以实质价值消解内在价值的同时统摄固有价值与工具价值。在文本梳理的基础上,本文也考察了克里考特的后现代视域的逻辑依据与实践可能。具体地,本文指出:1克里考特以实证科学之认知来架构形上本体的思路混淆了科学命题与玄学命题的区别内涵;2建立在消解三类性质基础上的"实质价值"架空了价值本身的应然引力;3克里考特过分地强调了整体与部分的对立从而容易陷入逻辑悖论;4克里考特以关系消解实体的本质是将关系作了唯内在性的理解,而这种理解是缺乏支持力的。特别地,克里考特以整体解析部分并以关系消解个体的进路将导致伦理虚无主义。针对克里考特理论的缺陷,本文指出,以"关系"为纽结的部分与整体之间是体用统一的;而实体间的关系,既具有内在性的一面,也具有外在性的一面;并且,关系的外在性既具有本然的维度,也具有应然的维度,即,它是道德实践的必要前提。  相似文献
