Adaptive wetland management in an uncertain and changing arid environment Ecology and Society
Downard, Rebekah; Utah State University; rdownard8@gmail.com; Endter-Wada, Joanna; Utah State University; joanna.endter-wada@usu.edu; Kettenring, Karin M.; Utah State University; karin.kettenring@usu.edu.
Wetlands in the arid western United States provide rare and critical migratory bird habitat and constitute a critical nexus within larger social-ecological systems (SES) where multiple changing land-use and water-use patterns meet. The Bear River Migratory Bird Refuge in Utah, USA, presents a case study of the ways that wetland managers have created adaptive management strategies that are responsive to the social and hydrological conditions of the agriculture-dominated SES within which they are located. Managers have acquired water rights and constructed infrastructure while cultivating collaborative relationships with other water users to increase the adaptive capacity of the region and decrease conflict. Historically, water management involved diversion...

Bescherming en beheer van het Schelde-estuarium OMA
de Haan, W.; Van den Bergh, E.; Jacobusse, C..
The ecological quality ofthe Scheldt has been strongly affected by deepening, reclaiming and polluting the water of the river. The use of national instruments of protection has unsufficiently contributed to the recovery of the estuarium. Field managers of nature-areas have succesfully taken the negative effects of the other functions as starting point into their management. The program for compensation of lost nature on behalf of the recent deepening will be evaluated next year, and adapted if necessary. The European directives for nature, water and fishery become more and more important. They play a big role in the long term vision for the Scheldt-estuarium.

Can the lack of coordination between an agricultural authority and a water agency generate inefficiencies? AgEcon
Martin, Elsa; Stahn, Hubert.
The point of departure of this work is the situation occurring in the Crau area (South-East of France). In this region, organic farmers use surface water for irrigation and excess water percolates into an aquifer that is used as a source for local residents. In contrast to the standard framework, agricultural production thus increases groundwater levels. In this paper, using a dynamic model, we derive the myopic and socially optimal food and water consumption paths. The first aim is to bring to the fore that an intervention is needed and that, in such a specific case, the environment can be protected thanks to some "good" production incentives. We then analyze the problem of coordination that can occur when two distinct local authorities - an agricultural...

Determining the Price-Responsiveness of Demands for Irrigation Water Deliveries versus Consumptive Use AgEcon
Scheierling, Susanne M.; Young, Robert A.; Cardon, Grant E..
A water-crop simulation/mathematical programming model of irrigation water demand in northeastern Colorado is formulated to develop an original concept of derived demand for consumptive use of water. Conventional demand functions for water deliveries are also developed, and the effect of hypothetical price increases on both consumption and delivery are illustrated. Findings indicate that demand elasticity estimates are quite sensitive to model specification, and consumptive use demand tends to be significantly less price-responsive than delivery demand. Thus price incentives are likely to have only limited impacts on basin-wide water consumption and would not make much additional water available for emerging demands.

Discussion: Water Scarcity–Future Uses and Implications for Policy AgEcon
Willis, David B..
The three articles presented at this invited session examine the evolution of water policy planning and the implementation of regulatory tools to achieve water conservation objectives. Two articles focus on Texas water issues and the third focuses on the Georgia planning experience. Each article clearly illustrates the value of sharing advances in hydrologic and economic modeling with local community stakeholder groups to facilitate the credible development of regional water management plans. Moreover, each article hints that stronger regulatory tools may be needed to achieve long-run policy objectives.

Economics of Reduced Water Allocations: Estimating Impacts on the Northern Victorian Dairy Industry AgEcon
Gyles, Oliver; Baird, Catherine A.; Brown, Stuart.
Water use efficiency data was used to estimate the impact of reducing sales water allocations on a range of irrigated dairy farms categorised according to intensity of water right. The expected deficiency in available water was estimated for each farm category on the basis of historical demand for sales and the potential production loss estimated. The cost of substitution through management options of purchasing 1) water right (with associated sales), 2) temporary sales water, or 3) feed supplements as grain or hay and silage was calculated. Purchase of water right was found to be the cheapest option and the regional transfer volume required estimated at 93 GL of water right valued at A$ 60.7 million. The average transfer requirement was estimated at 31 ML...

Environment protection: challenges for future farming AgEcon
Pannell, David J..
There has been increased public demand for environment protection, including in rural areas. Government programs and policies have responded to these demands in various ways, such as by attempting to increase farmer awareness of environmental issues, increasing budgets for rural environmental programs, increasing environmental regulation, purchasing water from irrigators for environmental purposes, and encouraging farmer adoption of new environmentally friendly practices. These changes create a number of challenges for farmers, including challenges related to maintaining farm productivity, meeting community expectations, living with less water and evaluating new opportunities. These challenges are described and discussed. While there certainly are...

Flood Planning and Climate Forecasts at the Local Level AgEcon
Wernstedt, Kris; Hersh, Robert.
We examine the use of El Nino-Southern Oscillation (ENSO) forecasts for flood planning in the Pacific Northwest. Using theories of resource mobilization as a conceptual foundation, the paper relies on: 1) case studies of three communities vulnerable to flooding that have had access to long-term forecasts of ENSO conditions; and 2) analysis of data collected from a survey of nearly 60 local emergency managers, planners, and public works staff. We find that understanding the regulatory machinery and other institutions involved in using climate forecasts is critical to more effective use of these forecasts. Forecast use could be promoted by: 1) an extension service to broker climate information; 2) the identification or creation of federal authorities to fund...

Governance for Resilience: CALFED as a Complex Adaptive Network for Resource Management Ecology and Society
Booher, David E.; Center for Collaborative Policy, California State University Sacramento; dbooher@berkeley.edu; Innes, Judith E.; Department of City and Regional Planning, University of California Berkeley; jinnes@berkeley.edu.
A study of California’s water planning and management process, known as CALFED, offers insights into governance strategies that can deal with adaptive management of environmental resources in ways that conventional bureaucratic procedures cannot. CALFED created an informal policy-making system, engaging multiple agencies and stakeholders. The research is built on data from 5 years of field work that included interviews with participants, review of documents, and observation of meetings. We argue that CALFED can be seen as a self-organizing complex adaptive network (CAN) in which interactions were generally guided by collaborative heuristics. The case demonstrates several innovative governance practices, including new practices and norms for...

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...

Health impacts of small reservoirs in Burkina Faso. AgEcon
Boelee, Eline; Cecchi, Philippe; Kone, Andre.
In Burkina Faso, at least 1,700 small reservoirs have been constructed, most of them during the last 30 years. Numerous and scattered, these beneficial multipurpose systems combine productive with domestic water uses. However, their environmental and health impacts remain insufficiently documented. This report combines data from different sources into syntheses and national maps, with a focus on water-related diseases. The mitigation of negative impacts requires an integrated approach to specifically identify the enhancing and limiting factors that influence environmental impacts and the transmission of diseases around reservoirs. Public awareness campaigns need to accompany the promotion of preventive and curative measures and the development of...
