Spatial planning, water and the Water Framework Directive: insights from theory and practice 总被引:1,自引:0,他引:1
JEREMY G CARTER 《The Geographical journal》2007,173(4):330-342
Water is fundamental to the health of the biosphere, strong economic growth and human social well-being. Despite its relative scarcity and absolute importance to life on earth, fresh water resources are often used inefficiently or polluted unnecessarily. Policymakers must work towards developing approaches to balance human demands for water with the water requirements of ecosystems. The European Water Framework Directive, which aims to encourage the sustainable management and protection of freshwater resources, brings this agenda into sharp focus in Europe. Land use change and environmental quality are closely related, and the nature and location of development can significantly influence both the generation and resolution of environmental problems. This places spatial planning, which provides a framework for regulating the development and use of land, in a strong position to affect water quantity and quality issues and thus to aid the achievement of the Directive's goals. In particular, spatial planning has an important function in integrating the use and management of land and water more closely than is presently the case. This paper explores the potential and actual role of spatial planning in addressing challenges associated with the water environment. This enables an assessment to be made of the extent to which spatial planning can help to meet the goals of the Water Framework Directive. 相似文献

One of the consequences of the post-socialist transformation of Eastern and Central Europe and the Former Soviet Union is the emergence of energy poverty, a condition where households are living in inadequately heated homes. This paper examines the institutional and demographic underpinnings of energy poverty in Macedonia and the Czech Republic, two post-socialist states with divergent development paths. It has been established that more than 50% of Macedonian households may be suffering from domestic energy deprivation, while the same figure is less than 10% in the Czech case. The notion of a ‘hidden’ geography of poverty encapsulates the character of domestic energy deprivation among these populations. The problem has been invisible to decision-makers to date, due to its private character and non-conformity to conventional poverty-amelioration methods. 相似文献

柳林泉域岩溶地下水资源可开采量的确定 总被引:2,自引:0,他引:2
柳林泉域内赋存丰富的岩溶地下水资源,目前还没有大规模的开发利用,运用丰富的水文地质资料确定了泉城内的水文地质参数,概述了泉城含水系统的详细情况,用泉流量恢复法与均衡法计算并比较了泉域岩溶地下水资源量,在计算不同保证率的情况下对泉域的可开采资源量进行了分配,为离柳矿区的发展,合理利用岩溶地下水资源提供了较为可靠的依据。 相似文献

Bison (Bison spp.) occurred in eastern Washington state during the late Quaternary. This area is considered to be peripheral to the center of this taxon's natural range. Bison in the plains east of the Rocky Mountains, the heart of this range, underwent diminution during the late Quaternary, and apparently also did so in other, peripheral areas. A ratio diagram of measurement data derived from eight zooarchaeological collections of bison remains recovered from eastern Washington, in combination with the presence of both sexes and all age classes of individuals, indicate that local bison may have also undergone diminution there. There are, however, a relative paucity of bison remains during the middle Holocene and an apparent 2000-year absence of bison from eastern Washington at this time. As a result, the hypothesis that bison became smaller elsewhere and then immigrated to eastern Washington cannot be falsified. Both the diminution and the fluctuating abundance of bison appear to be responses to forage quality and quantity. 相似文献

在大地电磁测深法中,曲线类型的分析划分是资料解释流程中相当重要的一环。实测曲线类型不仅反映了测区地下地质构造的电性特征,更重要的是通过曲线类型的划分与分类,可定性地掌握测区地质构造单元的格局,制定相应的定量解释方法,有效地克服地质推断的多解性。本文在本文采用聚类分析的方法对MT曲线进行了分类,以求克服目前简单分类法,捕抓曲线特征中更深层的一些信息,并给出了应用实测。 相似文献
