Water shortages and extreme events: a call for research
Water shortages as a result of extreme weather events, such as flooding and severe cold, have the potential to affect significant numbers of people. Therefore, the need to build robust, coordinated plans based on scientific evidence is crucial. The literature review outlined in this short communication was conducted as part of a joint Drinking Water Inspectorate and Health Protection Agency ...

Water rate to manage residential water demand with seasonality: peak-load pricing and increasing block rates approach
A strong seasonal demand for water occurs in many tourist areas, which might exacerbate the water shortage problems. Water pricing is a key instrument for water use management; therefore, the objective of this work was to design a variable water rate to examine the seasonal water demand in water-scarce regions. The proposed water rate combines the peak-load pricing (PLP) and increasing block ...

Is desalination the most sustainable alternative for water-shortage mitigation in Israel?
Significant progress in seawater desalination technology has lowered its costs considerably, making it an attractive option to policy makers in countries facing water shortages. However, in making the decision to implement desalination, two issues are often ignored: firstly, seawater desalination is also associated with external costs. Secondly, alternative measures of managing water shortage may ...

The electricity–water nexus: is a crisis imminent?
Several recent studies have warned that there will be widespread water shortages in many regions of the USA in the near future largely because of high demand for water in the production of electricity. This study reviews studies addressing electricity generation and water availability and concludes that electricity production is not likely to lead to water shortages in most regions for ...

Reducing water consumption in industry through flow analysis and simulation: a case study from India
Increasing water shortages in some countries is forcing the industrial enterprises to secure their own supply of process water. Reducing water consumption and closing water cycles is essential in order to safeguard industrial water supply. The various ways of implementing water saving measures in a company can be highlighted via a status-quo analysis involving a simulation of the actual ...

A simulation impact evaluation of social-economic development on water resource use
Due to the fast growth of the economy and population, the water scarcity issue has aroused widespread critical concern. In fact, reasonable structure, adaptive patterns and effective regulation of the economy, society and water resources can bring a harmonious future. Therefore, the study of how to balance economic social growth and water resources is of great importance. A model of the water ...

Evaluation of urban water resource security under urban expansion using a system dynamics model
Because of rapid economic development and urbanization, water shortage has become a serious problem in the arid region of China. To investigate urban water resource security, the supply demand pressure of water resources and the urban expansion index were analyzed under different developing scenarios in this paper. Based on the economic data of Urumqi, a typical inland city in the arid area, ...

Population and water in the Middle East: the challenge and opportunity for law
Although it is commonplace today to argue that population growth drives many or most environmental problems, Jane Jacobs has questioned the prevailing view, noting that the empirical evidence for it is actually rather slim. This article presents a case study of the pressures that population places on water in the Middle East, concluding that the countries of the region suffer from inappropriate ...

Impact of intermittent water supply on water quality in Lebanon
Lebanon in general and its capital, Beirut, suffer from water shortage due to the increasing water demand and the lack of proper management despite its abundant water resources. An intermittent water supply strategy was implemented in order to minimise deficiency problems. This, however, can seriously affect water quality due to the potential suction of non-potable water by negative pressures, ...

Criteria and Performance Measures for Iskandar Malaysia Urban Water Shortages Management
In Malaysia, usage of performance indicators are still new and evaluation of water utilities performance in each state are not standardized. In Iskandar Malaysia, with shortages predicted by the year 2025, new water alternatives and management measures needed to overcome this problem. Thus, criteria and performance measures were outlined for the selection of alternative water supply management. ...

A critical review of groundwater utilization and management in China's inland water shortage areas
Groundwater, as an important store of freshwater, plays a more critical role in sustaining the ecosystem and enhancing human adaptation to changing climate than surface water. In particular, it can store large volumes of water to naturally buffer the pressure of water shortage against seasonal changes in rainfall. However, groundwater itself is also vulnerable to climate change, showing a ...

Examining the effectiveness of residential water demand-side management policies in Israel
Increasing global water shortage is enhancing the need for water management policies, such as water demand policies. This study presents the main water demand-side management policies implemented in Israel, designed to reduce water demand in the urban sector, and subsequently examines their effectiveness by an econometric model, based on residential water consumption data. The main findings ...

Summer precipitation prediction in the source region of the Yellow River using climate indices
The summer precipitation from June to September in the source region of the Yellow River accounts for about 70% of the annual total, and its decrease would cause further water shortage problems. Consequently, the objectives of this study are to improve the understanding of the linkages between the precipitation in the source region of the Yellow River and global teleconnection patterns, and ...
