Última La demanda de agua para uso doméstico y comercial en Texcoco de Mora, Estado de México. Colegio de Postgraduados Gómez Ugalde, Sandra Gabriela. Con el objetivo de cuantificar la demanda de agua promedio por usuario en el sector doméstico y comercial en Texcoco de Mora, Estado de México, caso particular del servicio medido; ante la problemática de la sobreexplotación de los mantos en el Acuífero de Texcoco, se planearon dos modelos econométricos de regresión múltiple. Con estos se determinaron las principales variables que afectan la demanda de agua por usuario y bimestre, los cuales son: el precio o tarifa del agua, el ingreso, la tarifa eléctrica y el consumo de agua del bimestre anterior.Los resultados señalan que la demanda responde de manera inelástica al precio en el sector doméstico y elástica en el sector comercial.

Ano: 2011 URL: http://hdl.handle.net/10521/487 World water demand and supply, 1990 to 2025: scenarios and issues AgEcon Seckler, David; Amarasinghe, Upali A.; Molden, David J.; de Silva, Radhika; Barker, Randolph. Presents two alternative scenarios of water demand and supply for 118 countries over the 1990 to 2025 period and develops indicators of water scarcity for each country and for the world as a whole. This study is the first step in IWMI's long-term research goal: to determine the extent and depth of water scarcity, its consequences for individual countries and what can be done about it.

Ano: 1998 URL: http://purl.umn.edu/61108 Economics and politics of water resources development: Uda Walawe Irrigation Project, Sri Lanka AgEcon Molle, Francois; Renwick, Mary E.. The Uda Walawe Irrigation and Resettlement Project (UWIRP) located in the Southern dry zone of Sri Lanka was initiated in the early 1950s. The original plan for the UWIRP was a highly ambitious social, economic and physical engineering project aimed at creating a modern, profitable agriculture sector. This report examines the history of water resources development and investment decisions for the UWIRP over a period of 50 years and uncovers underlying processes that shaped the evolution of the project and highlights the limitation of viewing development as a mere set of technical and social engineering endeavors.

Ano: 2005 URL: http://purl.umn.edu/44525 Do Consumers React to the Shape of Supply? Water Demand under Heterogeneous Price Structures AgEcon Olmstead, Sheila M.; Hanemann, W. Michael; Stavins, Robert N.. Urban water pricing provides an opportunity to examine whether consumers react to the shape of supply functions. We carry out an empirical analysis of the influence of price and price structure on residential water demand, using the most price-diverse, detailed, household-level water demand data yet available for this purpose. We adapt the Hausman model of labor supply under progressive income taxation to estimate water demand under non-linear prices. Ours is the first analysis to address both the simultaneous determination of marginal price and water demand under block pricing and the possibility of endogenous price structures in the cross section. In order to examine the possibility that consumers facing block prices are more price-responsive, all else...

Ano: 2002 URL: http://purl.umn.edu/92699 Welfare and Distribution Effects of Water Pricing Policies AgEcon Ruijs, Arjan. In this paper, distribution and welfare effects of changes in block price systems are evaluated. A method is discussed to determine, for a Marshallian demand function, equivalent variation in case of a block price system. The method is applied to analyze welfare and distribution effects of changing water prices in the Metropolitan Region of São Paulo. Results show that there is a trade off between average welfare and income distribution. A pro-poor price system may result in lower average welfare than a flat price system, but in higher individual welfare for the poor. Moreover, there is a trade off between revenues for the water company and income distribution. Even though pro-poor price systems may not be as good for average welfare as flat price systems,...

Ano: 2007 URL: http://purl.umn.edu/7441 Evaluation of historic, current and future water demand in the Olifants River Catchment, South Africa AgEcon McCartney, Matthew P.; Arranz, Roberto. Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were...
