Adjustment to Salinity in Irrigation Regions: Ex Post Evaluation of the Tragowel Plains Plan AgEcon
Baird, Catherine A.; Gyles, Oliver.
An early-mid project evaluation of the benefits and costs of the Tragowel Plains Salinity Management Plan estimated the net cost after six years at A$ 5.5 million. The cumulative cash flows for the water transfer, drainage and halophyte programs were all positive with benefit to cost ratios (BCRs) of 3.2, 1.3 and 1.1. Inclusion of estimated future benefits and costs to year 30 gave BCRs of 13.7, 1.3 and 4.0 with net present values (NPVs) of A$ 18.8 million, 2.5 million and 0.4 million respectively. Net costs for other integrated programs including salinity survey, whole farm planning, facilitation of structural adjustment, revegetation and coordination of implementation reduced the NPV of the first six years of implementation to A$ 12.1 million. The water...

China’s water pricing reforms for irrigation: effectiveness and impact AgEcon
Liao, Yongsong; Gao, Zhanyi; Bao, Ziyun; Huang, Qingwen; Feng, Guangzhi; Xu, Di; Cai, Jiabin; Han, Huijing; Wu, Weifeng.
Irrigation occupies a central position in China’s crop production. However, due to low per capita water resources, much worse, unevenly distributed over regions and time and the rapid increase of water diversions to non-irrigation sectors, irrigation water shortages have become a very serious problem. Without the adoption of effective measures this problem may even threaten China’s food security. Currently, irrigation efficiency is very low in general, irrigation water prices cannot fully recover water supply costs, and irrigation facilities are aging due to the lack of funding for O&M (operation & maintenance). Since water prices are regulated by the government, and not determined by the market, water prices did not work effectively in water...

Conflicts over Water in the Upper Klamath Basin and the Potential Role for Market-Based Allocations AgEcon
Jaeger, William K..
The curtailment of irrigation on the Klamath Reclamation Project in 2001 is estimated to have cost farmers more than $35 million. This study examines how alternative water allocations among irrigators in the Upper Klamath Basin could have lowered those costs. Per acre marginal water values vary by a factor of 20 due primarily to variations in soil productivity, with the highest productivity lands concentrated in the federal Project. A linear programming model estimates costs for alternative allocations. Findings indicate that compared to the 2001 allocation, costs could be reduced by 75% with a market-based approach.

Eficiencia de las reglas de asignacion de agua en el regadio: asignacion a traves de mercados, de la regla proporcional y de la regla uniforme AgEcon
Goetz, Renan-Ulrich; Martinez, Yolanda Martinez; Rodrigo, Jofre.
En el presente trabajo se simula la introducción de diferentes métodos de reparto del agua en la agricultura, y se aplican a una zona de regadío del valle central del Ebro. En concreto, se han escogido tres métodos diferentes de asignación con el fin de comparar su eficiencia económica. Además del actual sistema proporcional y el sistema de mercado, se simulará la introducción de la regla de reparto uniforme, desarrollada en la teoría de la elección social. Los resultados permiten concluir que aunque el mercado de agua conduzca a mejores resultados globales en todos los casos, la regla uniforme puede resultar una alternativa interesante cuando las dotaciones de agua se encuentran en el intervalo habitual, mientras que en situaciones de escasez severa de...

Groundwater policy: issues and alternatives in India AgEcon
Moench, Marcus.
This paper reviews policy-related issues discussed in recent conferences that will affect groundwater development and management efforts in South Asia. Emphasis is given to policy issues surrounding emerging groundwater depletion and quality concerns, and issues concerning the equitable development of groundwater for poverty alleviation. The paper outlines the range of services that depend on groundwater resources and outlines the range of services that depend on groundwater resources to provide these services, and the complications stemming from the fragmented approach taken to water management throughout the region. A range of responses dealing with the management of the physical system is identified. In conclusion , the paper discusses institutional...

Institution of Ground Water Market for Management of Ground Water Resource: A Study from Assam in Northeast India AgEcon
Dutta, Mrinal Kanti.
Assam in the north eastern region of India has the endowments to ensure agricultural growth in the sense that the state has huge reserves of ground water in addition to the enormous surface water availability. Returns to both labor and capital in the state are considered high as potentials for exploiting the existing technology are yet largely untapped. As insufficient irrigation infrastructure is identified as a major constraint on exploiting such potentials, investment for expanding irrigation capacity is needed. At the same time, putting necessary institutions in place to ensure that the installed capacity is effectively utilized is also equally important. Compared to relatively larger government irrigation schemes, the privately owned and operated tube...

INTEGRATED ECONOMIC-HYDROLOGIC WATER MODELING AT THE BASIN SCALE: THE MAIPO RIVER BASIN AgEcon
Rosegrant, Mark W.; Ringler, Claudia; McKinney, Daene C.; Cai, Ximing; Keller, Andrew; Donoso, Guillermo.
Increasing competition for water across sectors increases the importance of the river basin as the appropriate unit of analysis to address the challenges facing water resources management; and modeling at this scale can provide essential information for policymakers in their resource allocation decisions. This paper introduces an integrated economic-hydrologic modeling framework that accounts for the interactions between water allocation, farmer input choice, agricultural productivity, nonagricultural water demand, and resource degradation in order to estimate the social and economic gains from improvement in the allocation and efficiency of water use. The model is applied to the Maipo River Basin in Chile. Economic benefits to water use are evaluated for...

Regulation versus pricing in urban water policy: the case of the Australian National Water Initiative AgEcon
Byrnes, Joel; Crase, Lin; Dollery, Brian.
The Australian National Water Initiative (NWI) builds on the foundations of earlier water reforms, attempts to correct earlier errors in both policy and its implementation, and seeks to better define some of the policy aims with the benefit of hindsight. However, despite the deliberate effort to improve on earlier reforms, the NWI still embodies a significant economic paradox. Although policymakers have shown their faith in the market insofar as allocating water between competing agricultural interests is concerned, they have not shown the same degree of faith in the ability of urban users to respond to price signals. This paper attempts to shed at least some light on this question by examining the responses of a number of State governments across...

Right-to-Choose Auctions: A Field Study of Water Markets in the Limari Valley of Chile AgEcon
Alevy, Jonathan E.; Cristi, Oscar; Melo, Oscar.
Field experiments were conducted with farmers in the Limarí Valley of Chile to test extant theory on right-to-choose auctions. Water volumes that differed by reservoir source and time of availability were offered for sale by the research team. The auctions were supplemented by protocols to elicit risk and time preferences of bidders. We find that the right-to-choose auctions raise significantly more revenue than the benchmark sequential auction. Risk attitudes explain a substantial amount of the difference in bidding between auction institutions, consonant with received theory. The auction bidding revealed distinct preferences for water types, which has implications for market re-design.

The Impacts of Water Management Policies on Agricultural Production in Australia - An Economic Analysis AgEcon
Burdack, Doreen; Baldwin, Claudia; Lotze-Campen, Hermann; von Witzke, Harald; Biewald, Anne.
In the Australian Murray-Darling Basin (MDB) the combination of severe and prolonged droughts and historic water management decisions to divert water for cultivation stressed water resources in such an intensive manner that wetlands went dry and rivers are now far from a natural flow. More appropriate water management policies must be implemented to restore ecological function. However, with 39 % of Australia’s total value of agricultural production, transitions in use need to be managed to minimise economic and social impacts on basin communities while they adjust. Recent studies estimate that industries with high water usage but lower or more volatile value products will be impacted more than higher value products. Therefore, this study’s focus is to...
