Residential Water Consumption: A Cross Country Analysis AgEcon
Grafton, R. Quentin; Kompas, Tom; To, Hang; Ward, Michael B..
Survey data from over 1,600 households in ten countries were used to analyse the determinants of residential water demand. Results show that in every country the price elasticity is negative and statistically significant. Households that do not have to pay for the water they use (volumetric water charges) consume about a third more water than similar households that do have to pay such charges. Consumers’ attitudes do not have a statistically significant effect on total water use, although they do increase the probability of households using some water saving behaviours. Volumetric water charges also have an impact on the adoption of water saving actions. Full-cost water pricing appears to be a highly effective instrument to manage residential water...

Does Marginal Price Matter? A Regression Discontinuity Approach to Estimating Water Demand AgEcon
Nataraj, Shanthi; Hanemann, W. Michael.
Although complex pricing schedules are increasingly common in utility billing, it is difficult to determine whether consumers respond to complicated marginal prices because price changes are often confounded with simultaneous demand shocks or non-price policies. To overcome this challenge, we exploit a natural experiment - the introduction of a third price block in an increasing block pricing schedule for water - in Santa Cruz, California. Using a regression discontinuity design, we find that consumers do respond to changes in marginal price. Doubling marginal price led to a 12% decrease in water use (500 cubic feet per bill) among high-use households.

India’s water future to 2025-2050: business-as-usual scenario and deviations AgEcon
Amarasinghe, Upali A.; Shah, Tushaar; Turral, Hugh; Anand, B.K..
With a rapidly expanding economy many changes are taking place in India today. The business-as-usual (BAU) scenario, which assumes the continuation of current trends of key water demand drivers, will meet the future food demand. However, it leads to a severe regional water crisis by 2050, where many river basins will reach closure, will be physically water-scarce and will have regions with severely overexploited groundwater resources. While the alternative scenarios of water demand show both optimistic and pessimistic water futures, the scenario with additional productivity growth is the most optimistic, with significant scope for reducing future water demand.

Estimating Urban Residential Water-Demand with Increasing Block Prices: The Case of Perth, Western Australia AgEcon
Xayavong, Vilaphonh; Burton, Michael P.; White, Benedict.
This study uses panel data at suburb level to estimates the elasticity water demands in Perth, Australia from 1995 to 2005. After deriving the consumer’s water demand under a non-linear budget constraint, we estimate the water demand model, which accounts for how water (and other purchased goods) is used to satisfy fundamental desires of the household. We have applied the specification of price that provided the correctly estimated marginal price from the block tariff structure, and employed a maximum likelihood estimation technique to tackle the endogeneity and heteroskedasticity issues. Our estimation of water demand price elasticities are slightly higher (more elastic) than previous study in Perth, but broadly in line with other estimates in the...

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.

Groundwater Management and the Cost of Reduced Surface Water Deliveries to Urban Areas: The Case of the Central and West Coast Basins of Southern California AgEcon
Sunding, David L.; Hamilton, Stephen F.; Ajami, Newsha K..
The Central and West Coast groundwater basins (“basins” or “Central and West Coast Basins”) are located in southern Los Angeles County. Groundwater produced from these basins provides approximately forty percent of the water supply for residents and businesses in all or parts of 43 cities. The 4 million residents in the area comprise more than ten percent of the total population of the State of California. This report measures the economic costs and benefits of the various program elements encompassed by the proposed judgment amendments (Judgment Amendments) to pumpers extracting groundwater in the basins. Because those pumpers include water agencies, who collectively serve nearly 4 million customers the economic costs and benefits also extend to the...

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,...

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...

Spatial variation in water supply and demand across river basins of India AgEcon
Amarasinghe, Upali A.; Sharma, Bharat R.; Aloysius, Noel; Scott, Christopher A.; Smakhtin, Vladimir U.; de Fraiture, Charlotte.
India is a large country with regional differences in per-capita water supply and demand. Attempts to describe the water situation in India at a national level are often misleading due to the tremendous diversity in the water situation across the country. This Report analyzes the spatial variation of water supply and demand across river basins in India. The study identifies basins that are water-scarce because of inadequate water availability to meet the effective demand. It also identifies issues that are important for estimating the future water demand and for the formation of policy for future water-resources development and management.
