Water, a renewable natural resource that is indispensable both to human life and to economic processes, has had its hydrological cycle threatened by pollution and contamination of hydrological resources. In Brazil, in 1997, Law 9.433 established the river basin as the unit for territorial planning and management of water resources. The proposal presented in this paper has an integrating focus, aiming at pointing out indicators for the sustainable development of river basins. The indicators are analyzed through social, environmental, economic and political–institutional frameworks, supported by internationally accepted methodologies. The implementation of this kind of project requires a large and reliable data set. Thus, we propose gradual implementation of sustainable development diagnosis in the river basins. To begin this process, we selected three indicators—public water supply, public sewerage and municipal trash collection. The values obtained for these indicators were compared with those of the Millennium Development Goals (MDGs), which establish 50% reduction in them by 2015. The indicators were applied to the Guanabara Bay Watershed (GBW) in the state of Rio de Janeiro, Brazil as a case study.

International River Basins of the World   总被引:2,自引:0,他引:2  
It is becoming acknowledged that water is likely to be the most pressing environmental concern of the next century. Difficulties in river basin management are only exacerbated when the resource crosses international boundaries. One critical aid in the assessment of international waters has been the Register of International Rivers a compendium which listed 214 international waterways that cover 47% of the earth's continental land surface. The Register, though, was last updated in 1978 by the now defunct United Nations Department of Economic and Social Affairs. The purpose of this paper is to update the Register in order to reflect the quantum changes that have taken place over the last 22 years, both in global geopolitics and in map coverage and technology. By accessing digital elevation models at spatial resolutions of 30 arc seconds, corroborating at a unified global map coverage of at least 1:1 000 000, and superimposing the results over complete coverage of current political boundaries, we are able to provide a new register which lists 261 international rivers, covering 45.3% of the land surface of the earth (excluding Antarctica). This paper lists all international rivers with their watershed areas, the nations which share each watershed,their respective territorial percentages, and notes on changes in or disputes over international boundaries since 1978.  相似文献

Global water demands are likely to increase steadily in the foreseeable future due to increases in population growth in the developing world and changes in per capita demand as a result of changing lifestyles in nearly all parts of the world. Since all exclusively national sources of water that could be used economically have already been developed, or are in the process of development, there would be tremendous pressure to develop international water bodies, which are often the only new sources of water that could be used cost-effectively. These international water sources have not been developed in the past, primarily because of absence of agreements on water allocations between the countries concerned. Thus, the potential for conflicts in the 21st century between the countries on various international water bodies is likely to be much higher than at present. International organizationscan play an important role as mediators in conflicts on international water bodies. However,except for Eugene Black, President of the World Bank, who played a critical role in the 1950s on the formulation of the Indus Water Treaty between India and Pakistan, their contributions have been somewhat marginal. These organizations have become increasingly risk-averse during the past three decades, and their leaderships have given the potentially thorny issue of development of international rivers a wide berth. In 1970, the United Nations decided to take up the case of the law of the non-navigable uses of international watercourses. Some 27 years later, the UN General Assembly approved, on 8 July 1997, a convention on this subject. The convention, though a useful step, is very broad, general and vague, and thus is likely to be of only limited help to the negotiators on the various international watercourses.Even when the convention is ratified, agreements on the development and management of international water bodies are likely to be achieved only through protracted negotiations between the countries concerned, as has been the case in the past.  相似文献

论可持续发展战略与水务一体化   总被引:10,自引:1,他引:9  
改革现行的水务管理体制,实现了水务一体化管理,才能保证可持续利用。我国现行的水务是多部门分割管理,造成管水量的不管水质管水源的不管供水,管供水的不管排水,管排水的不管治污。管治污的不管污水回用。本文从水资源可持续利用角度进行分析,提出为保证我国经济社会的可持续发展,必须建立统一的水务管理体制,以对区域的防洪、除涝、蓄水、供水、节水、水资源保护、污水处理及其顺用、地下水回灌等实行统一规划、统一取水中  相似文献

实施小城镇战略对乡镇供水的影响   总被引:1,自引:0,他引:1  
党的十五届三中全会《决定》指出,发展小城镇,是带动农村经济和社会发展的一个大战略。去年,中共中央、国务院又联合出台了《关于促进小城镇健康发展的若干意见》。最近,中共中央在关于制定“十五”计划的建议中,再次重申了积极发展小城镇的战略思想。从这一战略产生的背景以及实施的指导方针、原则和要求看,内涵十分丰富,对乡镇供水的发展至少会产生六个方面的影响。  相似文献

Conflict among riparian countries prevents them from making the best use of their shared water resources. A modality is needed in the global community to deal with international water bodies in a much better way. International organizations are expected to serve as a mechanism to mitigate conflicts among riparian countries. However, international organizations have so far achieved very limited success in acting in such a role. An international organization could act flawlessly as a mediator in a transboundary water system only when some critical conditions are met. This paper aims at delineating some prerequisites for international organizations to be successful in their involvement in an international water system. Four cases where international organizationshave either succeeded or failed in dealing with transboundary water issues, were reviewed. It was found that the following critical conditions need to be met for international organizations to succeed in their involvement in international water bodies: (a) willingness of riparian countries to cooperate, (b) involvement of decision makers at the highest level of basin countries, and (c) neutrality as a third party with financial assistance as 'stick and carrot'.  相似文献
