Abstract

Although the amount of water on our planet is relatively fixed, it remains essential for all living things as well as hydropower generation, navigation, industrial use, etc. It is also becoming increasingly necessary for the growth and economic well being of industry. It is vital, therefore, that this scarce resource is well managed to meet the needs of a growing population as well as the demands of increased industrialisation throughout Sudan. Water and raw materials may be transported for long distances to reach domestic consumers and industries. Domestic and industrial wastes, however, must be dealt with where they are generated. In large cities, waste management has been difficult because of rapid urban growth. Environmental and water pollution is now a major concern throughout Sudan. An integrated approach to tackle water pollution issues should be adopted by industries, communities, local authorities, central governments, and professionals working in the sector. Most polluters give little or no attention to the control and proper management of the polluting effluents. This may be due to lack of enforceable legislation and/or the fear of spending money on the treatment of their effluent prior to discharge. Furthermore, the fines imposed on offenders are generally too low and therefore do not deter would be offenders.  相似文献

Abstract

This study investigates smallholder farmers’ participation in and knowledge of village-based water user associations in north-western China, and analyzes their interplay with membership in water associations and installation and application of micro-irrigation systems. Using farmer survey data, a multivariate probit model is built to analyze the effects of influential factors. Results show significant effects of farmers’ perceptions of water shortage and its causes, attitudes to water conservation, village-based information, and incentives on the membership in water user associations and installation and application of micro-irrigation. Policies promoting micro-irrigation adoption should target decentralized water management and facilitate farmers’ participation.  相似文献

Abstract

The way water resources in the former Soviet Union (FSU) were managed in the second half of the past century had both positive and negative effects and contributed to the existing situation. On the one hand, extensive development of water resources led to the transformation of millions of hectares of virgin lands into agricultural production, providing millions of people with food and livelihoods. On the other hand, the over-exploitation of water resources led to drastic changes of the environment: many water bodies, such as lakes, small rivers, and delta wetlands dried up. The Aral Sea basin is one of the dramatic examples of the negative impacts of large-scale irrigation interventions. The state-controlled era of development in the Soviet period has a legacy of standardized procedures and rules formulated at the top. The shortcomings of such a water management included fragmentation, duplication, and a highly administrative approach without considering the needs of the environment and input of water users into planning, allocating, and managing of water resources. This paper presents an analytical view of the role and importance of water users organizations/associations (WUOs/WUAs) in the irrigated agriculture and under irrigation management transfer (IMT) in Central Asia region. International Water Management Institute (IWMI) and the Scientific Information Center of Interstate Coordination Water Commission (SIC ICWC) conducted the “Best Practices.” Projects including activities covered Syr Darya and Amu Darya basins of Central Asia. During the first stage of the project (01.04.1002-31.03.2002), the monitoring objects were: 30 district water management organizations (DWMO), eight WUAs, 58 collective farms (CCF), and 61 private farms (PPF) from eight provinces Central Asia) project for conserving water resources by involving water users into water savings. The primary strategy was to propagate application of inexpensive technical and managerial methods and measures to save water by users themselves. The project is a joint project of IWMI and SIC ICWC aimed to monitor and disseminate the best practices of water conservation initiated by water users. The first year of the “Best Practices” project accomplished a broader involvement of water users into the water conserving methods, therefore continuing the beneficial good water management practices. It also continued to involve the water supplying organizations and various groups of water users (collective farms, farmers, and water users' associations). The major interest was to analyze the impacts of the different water conservation and management practices on productivity of water use.  相似文献

日本水资源的管理和实施由多个政府部门和组织共同完成,"治水与用水分离,多龙管水"是日本水资源管理体制的最大特点。国土交通省负责制定水资源开发与管理政策、水供求计划、库区开发及与其他相关省厅局及机构间的综合政策协调;厚生劳动省负责居民生活用水供应管理;农林水产省负责农业用水供应;经济产业省负责工业供水和水力发电;环境省负责水质与环境保护。日本存在缺水、供水稳定性下降和饮用水安全等问题,其妥善应对水问题的策略包括促进健全水循环、中水回用、现有水利设施的高效利用、复兴与培养水文化、虚拟水战略等。今后日本将更加关注伴随气候变化、全球变暖而来的极端少雨、降雪减少及融雪提前等现象。  相似文献

水足迹在河北省水资源管理中的实证研究   总被引:4,自引:0,他引:4  
虚拟水和水足迹是当今水科学研究的新热点,被认为是解决粮食与水资源安全的重要策略,是衡量人类对水资源系统真实占有量的有效手段。首先介绍了虚拟水、水足迹的概念及其相关理论与计算方法,然后在可获取的实际资料的基础上,计算了2000-2007年河北省居民消费的虚拟水数量和水足迹总量。结果表明:全省8年间的虚拟水消费量在水足迹构成中所占比重最大,同时全省人均水足迹占有量逐年增加,但仍处于较低水平。研究结果可为河北省水资源的可持续管理决策提供相应的理论支持。  相似文献

Abstract

During the last seven years, the author has developed a new analytic framework for the understanding of out-stream flows in any catchment or region. This is termed the area's “hydrosocial balance” because the flows from which it is constructed are hydrosocial rather than hydrological. Until now this meta-theory has been limited to flow quantities. The present paper extends the scope of the hydrosocial balance to issues of water qualities. The conjoint framework is then applied to a case-study of an island in the English Channel—Jersey—well known for its agricultural outputs, its financial services sector, and its tourist industry. The paper shows how general lessons for integrated water resources management can be drawn from the Jersey fieldwork: a world in a grain of sand.  相似文献

Abstract

Hong Kong, now a Special Administrative Region of China, is a very special and unique place in the world. Although the territory is located in the humid subtropics, local water resources are very limited because of its geographical setting and physical environment. Hong Kong's urban water supply has its uniqueness and has gone through a history of developing local resources and transferring water from the East River (Dongjiang) basin in mainland China over the past half century. This paper aims to present the experience and challenges in developing water supplies and managing water resources in Hong Kong. First, the availability of local water resources is evaluated in the context of the territory's geographical setting. Second, the approaches adopted for developing urban water supply from local resources and more importantly, by making use of water imported from the Dongjiang, are presented and reviewed. Finally, a number of sustainability issues in Hong Kong's urban water supply are addressed with an emphasis on the problems and prospect of the Dongjiang water resources in the future  相似文献
