Cost Analysis for Water Distribution in Agriculture AgEcon
Dono, Gabriele; Giraldo, Luca.
This paper uses a Translog form to estimate the water distribution cost for an irrigation consortium. The consortium operates under conditions of the under-utilization of facilities; thus, to achieve full cost recovery, water charges must be set at a higher level than efficiency. As a consequence, farmers may decide to reduce their use of the public irrigation service and instead exploit groundwater. The estimated Translog function explains the costs of water services throughout the irrigated area, and identifies items for which pricing does not accentuate the competition between the use of surface water and groundwater. Based on the estimated coefficients, a hypothesis is hence presented for pricing water provided by the consortium.

DEA APPLICATION TO EVALUATE THE TECHNICAL AND ECOLOGICAL EFFICIENCY OF WATER PRICING POLICIES AgEcon
Giannoccaro, Giacomo; Prosperi, Maurizio; Zanni, G..
With the enforcement of the Water Framework Directive 2000/60/EC (WFD), policy makers are required to pursue the improvement of the use efficiency of the water resources in the agricultural sector. For this purpose, we suggest a methodology to perform an ex-ante analysis of the efficiency of water pricing policies, based on a two stage DEA technique, by which it is possible to disaggregate the technical and the ecological efficiency of the policy. According to our results, we found that, coherently with the WFD principles, the direct pricing methods show the highest levels of efficiency. However, we have also found that some indirect pricing methods show relatively high levels of efficiency. Therefore, since the high cost for the management and...

Dinâmica de sistemas aplicada à gestão de recursos hídricos em bacia hidrográfica AgEcon
Vieira, Wilson da Cruz.
The objective of this work was to analyze both the allocation of water among competing demands in a river basin and pricing policies for water. Based on a theoretical model that maximizes the net social benefits from the allocation of water over a finite period of time, it was used the dynamic systems approach to analyze various issues related to water resources management in a river basin, such as sustainability of water resources, and water pricing. The model was applied to the Araguari River Basin, located in the State of Minas Gerais.

Estimating the Willingness-to-Pay for Water in Georgia AgEcon
Elnagheeb, Abdelmoneim H.; Jordan, Jeffrey L..
In this paper, data from a 1992 telephone survey of Georgia residents were used to study people’s willingness-to-pay (WTP) for water as a commodity. A dichotomous contingent valuation method was employed to estimate the marginal scarcity rent of water. Results indicated that the average WTP was $15.10 above the current monthly water cost, or about 81 percent of current bills. The aggregate WTP for all of Georgia was estimated to be nearly $393 million, suggesting that water is underpriced.

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...

Irrigation water pricing between governmental policies and farmers’ perception: Implications for green-houses horticultural production in Teboulba (Tunisia) AgEcon
Chebil, Ali; Frija, Aymen; Thabet, Chokri.
A positive mathematical programming model was constructed in this study to assess the effect of three water pricing scenarios on Teboulba’s agricultural production systems. The effects of these scenarios were estimated for three groups of farmers from three irrigated districts. Results show that water demand in group 1 remains inelastic until achieving the price of 0.20 TD. A price above this level decreases water consumption, farmer’s incomes as well as seasonal labor demand. For groups 2 and 3, the water demand curves remain highly inelastic even with a full cost recovery price. However, once reaching this last price, the model shows important income reductions reaching 20% of the current observed income. Moreover, a pricing policy aiming to recover...

Irrigation Water Value Scenarios for 2015: Application to Guadalquivir River AgEcon
Mesa-Jurado, Maria A.; Piston, Juan Maximo; Giannoccaro, Giacomo; Berbel, Julio.
This paper reviews the application of a scenario for the 2015 agricultural policy and markets for the irrigated agriculture in Europe. Scenarios for irrigated agriculture 2015 are also described in detail including Reformed CAP and biomass demand. It is applied at the basin level for the Guadalquivir River in southern Spain. The methodology is based upon residual value of water and it combines budget and farm analysis at municipality level, with the Guadalquivir basin divided at 50 ‘comarcas’; in each of them 24 possible crops are selected with specific ‘comarca’ data bases. The 2015 scenario studies the present level of water use and value, and makes an analysis for 2015.This model allows the knowledge of water value and irrigated agriculture at ‘comarca’...

Latin American Agricultural Trade: The Role of the WTO in Sustainable Virtual Water Flows AgEcon
Niemeyer, Insa; Garrido, Alberto.
International agricultural trade has been growing significantly during the last decade. Many countries rely on imports to ensure adequate food supplies to the people. A few are becoming food baskets of the world. This process raises issues about the food security in depending countries and potentially unsustainable land and water use in exporting countries. In this paper, we analyse the impacts of amplified farm trade on natural resources, especially water. Farm exports and imports of five Latin America countries (Brazil, Argentina, Mexico, Peru and Chile) are examined carefully. A preliminary analysis indicates that virtual water imports can save valuable water resources in water-short countries, such as Mexico and Chile. Major exporting countries,...

PRECIFICAÇÃO DA ÁGUA EM PROJETOS DE IRRIGAÇÃO: UMA APLICAÇÃO DO MÉTODO PARAMÉTRICO DE ESTIMAÇÃO DE UMA FUNÇÃO INSUMO-DISTÂNCIA AgEcon
Resende Filho, Moises de Andrade; Araujo, Felipe Augusto de; Barros, Emanoel de Souza; Silva, Alexandre Stamford Da.
O aumento da pressão sobre os recursos hídricos tem levado muitos países a reconsiderarem os mecanismos utilizados na indução do uso eficiente da água. Isso é especialmente verdade para a agricultura irrigada, uma das principais consumidoras de água. Estabelecer o preço correto da água é um dos mecanismos de tornar mais eficiente a alocação da água. Contudo, precificar a água ainda é uma tarefa polêmica. Assim, o presente estudo aplica o método paramétrico de estimação de uma função insumo-distância na obtenção do preço-sombra ou disposição da firma a pagar por uma unidade adicional de água. São utilizados dados sobre a produção, área irrigada, utilização de insumos diversos, mão-de-obra, capital e volume de água obtidos de 41 unidades produtivas...

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...

Water Pricing and Valuation in Indonesia: Case Study of the Brantas River Basin AgEcon
Rodgers, Charles; Hellegers, Petra J.G.J..
The increasing demand for water and limited degree of cost recovery for irrigation water delivery are important challenges for policymakers in Indonesia. To meet the increasing demand for water, it is important to reduce water use in irrigated paddy cultivation, long the dominant consumptive user, and to divert water away from agriculture to domestic and industrial sectors. Reducing water use in irrigated agriculture can be achieved through various means, including rationing, improved user management, and water markets. The appropriate method depends on the situation specific to each basin. In the Brantas Basin in East Java, rationing is already practiced, but often leaves the non-licensed, (non-paying) irrigators with insufficient supplies. Moreover, very...

Water pricing options for the Middle Drâa River Basin in Morocco AgEcon
Heidecke, Claudia; Kuhn, Arnim; Klose, Stephan.
This paper discusses the possible effects of various ways of charging for water in an integrated modeling framework adapted to the Drâa River Basin in southeastern Morocco. Declining surface water availability in the basin has led to an increase in groundwater use for irrigation in recent decades, even though groundwater extraction is more costly than using surface water. The trade-off between the pricing of ground and surface water is discussed based on recursive-dynamic simulations over a ten-year period. The results identify groundwater pricing as an economically and environmentally favorable option, assuming that revenues from water charges are redistributed to farmers.

WATERSHED CONSERVATION AND EFFICIENT GROUNDWATER PRICING AgEcon
Roumasset, James A.; Pitafi, Basharat A.K..
Conserving the watershed can help to preserve the groundwater supplies by avoiding loss of recharge. Preventing overuse of available water through pricing reforms can also substantially increase benefits from groundwater stock. Since efficiency prices are generally higher than the inefficient, status quo prices, efficiency pricing may be politically infeasible and watershed conservation may be considered as an alternative. Using Pearl Harbor water district as an example, we find that pricing reform yields large welfare improvement (about $900 million) and is welfare-superior to watershed conservation unless the latter prevents over 10% loss of recharge. In addition, watershed conservation is more valuable at efficiency pricing than at the status quo prices.
