Water resources
Water resources are sources of water that are useful or potentially useful to humans. Uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water. 97% of water on the Earth is salt water, leaving only 3% as fresh water of which slightly over two thirds is frozen in glaciers and polar ice caps.[1] The ...

Water Resources: An Evolving Landscape
This chapter presents the history of thinking on water resources and how it has evolved over time. It analyzes paradigms proposed by the international community during the last half century in light of their decisive influence on the content (though not the implementation) of water policies in virtually all developed and developing countries. While paradigms have been an important part of global ...

Sustainable water resources governance
Sustainability – whatever its structure and its terminology – has become the concept that indicates how natural resources should be used and developed. It is however an enigmatic concept that is often accused of lacking substance and meaning. Nevertheless it has become increasingly embedded in the legal arrangements for the way in which natural resources – including water ...

Water resources management
Managing regional or national water resources demands the integration of patterns and processes of both natural and social systems. This is essential to achieve the optimum interaction of man and nature since every aspect of water use and disposal impinges on ecosystems to a greater or lesser extent. Sustainability is the key issue: how can sustainable yields by abstraction from rivers, ...

Privatization of Water-Resource Development
This paper analyzes the inefficiencies from market power and return-flow externalities in private construction of a water project. The model pays special attention to increasing groundwater pumping costs, project set-up costs, limited project capacity, and return flow to the aquifer. For a given capacity, the return-flow externality causes project owners to construct the project too late when the ...

Impacts of temperature and precipitation on the spatiotemporal distribution of water resources in Chinese mega cities: the case of Beijing
Water shortages in China have hindered development of mega cities, especially Beijing. Assessing the impact of temperature and precipitation on water resources is important. This study analyzed spatiotemporal variations and impacts of temperature and precipitation on water resources in Beijing from 1956 to 2013, using statistical and spatial analysis. The results showed the following. (1) ...

Integrating water resources management
The intention of this book is to showcase some of the most interesting aspects of IWRM in relation to the development and adoption of strategies and methodologies. Other related publications provide additional insights, see for example, the STRIVER website (www.striver.no) and the edited collection by Gooch and Stålnacke, (2010) on the ...

Will the water resources of Israel, Palestine and Jordan remain sufficient to permit economic and social development for the foreseeable future?
Scenario analysis suggests that by 2050 the population of Israel, the West Bank and Gaza Strip and Jordan will have grown from 17.2 million to between 21.1 and 38.5 million people. These population scenarios are compared to a range of water resource scenarios that consider the effect of climate change, a possible redistribution of the region's shared water resources as a result of a peace ...

The impact of privatisation on the sustainability of water resources
More than two and a half millennia ago, the Greek philosopher Thales of Miletus said “best of everything is water” (Biswas, 2005; p.229). Indeed, water still remains the source of life although the world has changed dramatically. Water is the most important natural resource on our planet Earth. It is the basis of life that all organisms depend on for survival. Water is ...

Priority General Authorisations in rights-based water use authorisation in South Africa
This article unravels the notions of justice in statutory water law in Sub-Saharan Africa in general and South Africa in particular. These laws, which allocate and regulate water resources, are licence (or permit) systems. Three forms of injustices are identified for small-scale water users who typically encompass all poor water users: the reinforcement of the historical injustices by which ...

Study of an evaluation method for water resources carrying capacity based on the projection pursuit technique
It is of great significance to establish a scientific and reasonable water resources carrying capacity evaluation system and evaluation method on the basis of studying the interdependence and mutual relations of water resources, society, economy and the ecological environment. This can guide water resources utilization and economic and social development planning, and promote the sustainable ...

Resolving water conflicts in the American West
The American West is defined first and foremost by aridity, scarcity, and variability of water resources. In response to this geographic imperative, the region has evolved a robust menu of legal, institutional, and community-based approaches to managing water and conflicts at local, state, and national levels. While far from perfect, this framework may offer lessons to other regions throughout ...
