Human activities have resulted in the loss of about half of the original 221 million acres of wetlands in the conterminous 48 states. Federal laws, policies, and programs have had major impacts on the nation's wetland resources. Initially, they encouraged and subsidized the draining and filling of wetlands, the flooding of wetlands behind dams, and the diversion and alteration of streamflows to riparian wetlands. More recently, federal policies have been directed to conserving and preventing further net losses. The focus of this study is on the impacts of federal policies on riparian wetlands, i.e., those formed at the interface of rivers and streams and uplands and that require occasional flooding to maintain the health of their ecosystems. The study...

In most urban cities across Australia, water restrictions remain the dominant policy mechanism to restrict urban water consumption. The extensive adoption of water restrictions over several years means that Australian urban water prices have consistently not reflected the opportunity cost of water (Edwards 2008). Given the generally strong political support for water restrictions and the likelihood that they will persist for some time, there is value in understanding householders’ attitudes in this context. More specifically, identifying the welfare gains associated with avoiding urban water restrictions entirely would be a non-trivial contribution to our knowledge. This paper is used to describe the results from a contingent valuation study that...

Evaluates the degree of success of water users in managing water allocations and deliveries in two irrigation district modules in the Lagunera Region of Mexico. Policies and practices are evaluated from the standpoints of the nature of planning rules, consistency, equity, and efficiency in implementation of the plans.

The Economic Value of Irrigation in the Texas Panhandle

Guerrero, Bridget L.; Wright, Andrew P.; Hudson, Darren; Johnson, Jeffrey W.; Amosson, Stephen H..

The Texas Panhandle relies largely on the Ogallala Aquifer for access to water for irrigated agricultural production. With current pumping rates and slow recharge rates, the aquifer will at some point in the future no longer be an economically viable source of water for agriculture. The objective of this study is to estimate the value of irrigated agriculture to the region. A hypothetical policy restriction is imposed which assumes a one hundred percent conversion to dryland agriculture. The study estimates the economic impact of such a change on producer income and the resulting socioeconomic impacts on communities in the region.

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...

Michailidis, Anastasios; Nastis, Stefanos A.; Loizou, Efstratios; Mattas, Konstadinos.

The use of irrigation water for agricultural production requires innovative and sustainable research and an appropriate transfer of water saving technologies. The main aim of this paper is to explore the irrigating behaviour of farmers examining factors affecting their decision to adopt novel water saving practices. In order to achieve the above aim both summary statistics and multivariate methodologies are employed. In particular, a two-step cluster analysis was used to explore the different adoption levels of water saving practices and a categorical regression model was estimated to explain this variation. Data were collected through a survey addressing 400 irrigators, carried out in 2008 in a typical Greek rural area. Results show that although...

When ENSO Reigns, It Pours: Climate Forecasts in Flood Planning

Wernstedt, Kris; Hersh, Robert.

Recent scientific and technical advances have increased the potential use of long-term seasonal climate forecasts for improving water resource management. This paper examines the role that forecasts, in particular those based on the El Nino-Southern Oscillation (ENSO) cycle, can play in flood planning in the Pacific Northwest. While strong evidence of an association between ENSO signals and flooding in the region exists, this association is open to more than one interpretation depending on: a) the metric used to test the strength of the association; b) the definition of critical flood events; c) site-specific features of watersheds; and d) the characteristics of flood management institutions. A better understanding and appreciation of such ambiguities,...

Potential of Artificial Wetlands for Removing Pesticides from Water in a Cost-Effective Framework

The purpose of this paper is to analyze the implication of wetland construction for the cost-effective design of a pesticide charge. A model is developed in order to show that, for a given target, the introduction of wetland construction can reduce overall abatement costs and can lower the input charge asked to the farmers. This result remains true as long as the cost of constructing a wetland is not too high. A numerical illustration is carried out in order to simulate pesticide regulations in a wine catchment in North-East of France

Determining the Price-Responsiveness of Demands for Irrigation Water Deliveries versus Consumptive Use

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...

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.

Through rapid assessment of existing literature and review of policy and other official documents, the report synthesizes the existing knowledge and gaps on policies and institutions and identifies key research issues that need in-depth study. The report provides an overview of the range of key livelihoods and production systems in the Blue Nile Basin (BNB) and highlights their relative dependence on, and vulnerability to, water resources and water-related ecosystem services. It also makes an inventory of current water and land related policies and institutions in the BNB, their organizational arrangements, dynamics and linkages and key policy premises. It highlights the major problems in institutional arrangements and policy gaps and makes suggestions for...

Economic Impacts of Reduced Delta Exports Resulting from the Wanger Interim Order for Delta Smelt

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.
