| 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... |

| The purpose of this report is to show the process of the intervention made through the implementation of the IWRM and Food Security Demonstration Project in Zambia. The report gives details of the project processes, showing the steps the project went through, the outcomes and its impact on the communities where it was implemented. The report is the result of a number of field visits made to the completed project sites, the sources of information have been; focus group meetings, interviews, discussions with key informants, beneficiaries the youth, male and female stakeholders and reviews of project activity reports, and direct observations. Therefore, what is presented here is a cumulative “factual and real time” opinion as to what has been observed and... |

| 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. |

| 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... |

| 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... |

| 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,... |
