  • Factors influencing water conservation behavior among urban residents in China's arid areas

    Insufficient academic attention has been paid to household water conservation behavior in arid and semi-arid areas of developing countries. Based on a questionnaire survey, this study analyzed factors influencing the water conservation behavior of urban residents in Zhangye City in China. Of the two variables addressed in the theory of reasoned action, attitudes toward water conservation had no ...

  • Investigating the effect of moral norm and self-identity on the intention toward water conservation among Iranian young adults

    This study aimed to investigate young adults’ intention regarding water conservation in Iran. To achieve this goal, we applied a modified theory of planned behavior, with moral norm and self-identity being two additional determinants of intention and behavior. A face-to-face survey (N = 428) was undertaken in two universities, in south-western Iran. The reliability and validity of the ...

  • An economic-efficiency analysis of water conservancy investment in Heilongjiang Province based on projection pursuit clustering and DEA models

    Water conservancy investment affects economic development. To scientifically analyze its economic efficiency, this paper employs a projection pursuit clustering model based on the real-coded accelerated genetic algorithm to reduce the number of output index systems for each year, and the relative economic efficiency is obtained for 13 cities in Heilongjiang Province during the period 2007–2012 ...

  • The politics of water conservation: identifying and overcoming barriers to successful policies

    Policies that increase the reliance of a water-supply organization (WSO) on water conservation have economic and environmental benefits, but some cities and WSOs have been reluctant to pursue such policies to their full extent. Previous research has identified barriers such as WSOs’ concerns with revenue loss and consumers’ concerns with changes in lifestyle. Based on interviews in four US ...

  • Aligning theory and measurement in behavioral models of water conservation

    Discussion in the water literature has called for research on the role of behavioral intentions in explanations of both water demand and water conservation. But previous research has suggested that individual-level motivations are not good predictors of metered household water consumption. Two possible reasons for the lack of association between intentions and actual water conservation are that: ...

  • Water conservation education as a tool to empower water users to reduce water use

    There is a finite supply of global fresh water available for human consumption, which is in great demand from both humans and the environment. As technology and populations increase, so do the demands and pressure on this limited resource. Demand far too often outstrips supply, requiring authorities to impose restrictions on water use. Recent research undertaken by Rand Water, in the Rand ...

  • Well Field Puts Growth On Track in Central Utah

    Drillers know they make an impact, but that doesn’t usually mean helping to supply water for hundreds of thousands of people. Steven Bryan sensed the scope of the Central Utah Water Conservancy District project when he got the call. Working the project, which involves several 24-inch wells that will supply a swath of central Utah, only confirmed the impact. ...

  • Waste not, want not: The potential for urban water conservation in California

    This report has been several years in themaking, in part because of the challenges ofcollecting data, developing methods andapproaches, and assembling the pieces, and in partbecause of the difficulty of finding funders who trulyunderstand the importance of conservation andefficiency for water policy and planning. Many peopleat the Pacific Institute played a role in preparing thisanalysis and ...

  • River Floodplain Maintenance-measures influencing roughness

    The maintenance of rivers and floodplains can make an important contribution to flood protection.  Waters conservation used to be understood mainly as verification of fast discharges, which was achieved through regular mowing. Furthermore, the waterways had to be navigable and accordingly required water depths had to be accomplished through maintenance measures (e.g. digging). Today, ...

  • Effectiveness of water saving devices and educational programs in urban buildings

    In this study different water saving measures (structural and non-structural) were implemented in different urban buildings. A monitoring program of water consumption was carried out to verify and compare the effectiveness of high-efficiency plumbing fixtures and educational programs in different types of buildings (two residential houses, two Middle Schools and two Sport Centres) located in a ...

  • Nestle and water conservation

    Is our world facing a larger environmental problem than climate change? Well, Nestle’s chairman, Peter Brabeck thinks so. According to Brabeck, water stress should be the world’s “first priority”, and according to the United Nations; one in three of the world’s population live in water stressed areas, and this is set to increase to one in two by ...

  • Rainwater-harvesting measures at BARC, Trombay, Mumbai: a case study

    The rapid dwindling of fresh water resources has focused worldwide attention on water conservation measures and integrated water management. Rain, the important component of the hydrological cycle, has therefore received enormous attention, and Rainwater Harvesting (RWH) has emerged as one of the most important and economical tools of water conservation. Bhabha Atomic Research Centre, with its ...

  • Detecting evolution trends in the recorded runoffs from the major rivers in China during 1950–2010

    Evolution trends as well as abrupt changes in recorded runoffs from the major rivers in China during 1950–2010 were investigated using the Mann–Kendall test and ordered clustering analysis. Results show that the recorded runoff series at ten key hydrometric stations on the major rivers in China are characterized by a general decreasing trend. A significant decrease has occurred at ...

  • Price elasticity of residential water demand in California

    This study used meta-analysis to assess the influence of price/price structures on residential water demand in two selected urban areas in California: East Los Angeles and South San Francisco. Monthly usage data for the years 2002–2011 were utilized to determine and compare price elasticities for periods when uniform and tiered rates were charged using fixed effects panel regression and ...

  • Biodegradation of artificial monolayers applied to water storages to reduce evaporative loss

    Repeat applications of an artificial monolayer to the interfacial boundary layer of large agricultural water storages during periods of high evaporative demand remains the most commercially feasible water conservation strategy. However, the interfacial boundary layer (or microlayer) is ecologically distinct from subsurface water, and repeat monolayer applications may adversely affect ...

  • Hidden oasis: water conservation and efficiency in Las Vegas

    Two of the West’s preeminent water organizations report Las Vegas Valley is sitting on an oasis of water and money savings. In their new report, the Pacific Institute and Western Resource Advocates find up to 40% of water could be saved in some sectors through improvements to indoor and outdoor water efficiency. They also found that through improving indoor water efficiency in particular, Las ...
