The intention of this paper is to develop a framework for a new IWMI research program on environmental water requirements of aquatic ecosystems and environmental aspects associated with irrigated agriculture in river basins and wetlands. The program will be implemented primarily in the context of developing countries, but the paper also examines research questions, which are of general importance for eco-hydrology and environmental water resources management. At the same time, it does not purport to be a comprehensive coverage of the environmental water research field but is designed primarily for attention of specialists dealing with wetlands, water resources management and sustainable agricultural development within sister CGIAR centers and other similar international agencies. It is envisaged that some ideas for future research presented in the paper will also be of interest to hydrologists and ecologists engaged in developing the concepts of environmental water requirements of aquatic ecosystems. The introduction of the paper sets up the purpose of the document. This is followed by a description of a framework, which links different levels of water resources use and conservation of natural aquatic systems with various management interventions. The main focus areas of the proposed research are then discussed. They include estimating water requirements of aquatic ecosystems, evaluating scenarios of development and impacts of irrigated agriculture on rivers and wetlands, allocating water with the consideration of environmental thresholds, etc. The paper also discusses possible research activities, which are associated with these focus areas and presents examples of specific research projects that could be pursued internally or in partnership with other national and international institutions.

This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.

Environmental information and systems play a major role in environmental decision making. As such, it is vital to understand the impact that they have on different aspects of sustainable environmental management, as well as to understand the opportunism they might present for further improvement. Environmental Information Systems: Concepts, Methodologies, Tools, and Applications is an innovative reference source containing the latest research on the use of information systems to track and organize environmental data for use in an overall environmental management system. Highlighting a range of topics such as environmental analysis, remote sensing, and geographic information science, this multi-volume book is designed for engineers, data scientists, practitioners, academicians, and researchers interested in all aspects of environmental information systems.

The impacts of climate change are beginning to be felt throughout the world, yet there is no clear explanation as to how these changes will alter our future. The research being conducted within the geospatial science field is pivotal to understanding the effects the global environment is experiencing. The Handbook of Research on Geospatial Science and Technologies is an essential scholarly reference source that evaluates the current methodologies and trends in geospatial science, and how these insights provide society with more efficient and effective ways to manage natural resources. Featuring discussions on relevant topics such as cartography, geographical information systems, remotely sensed data, and sustainability management, this publication is an informative resource for all academicians, students, scientists, and researchers that are interested in emerging developments within geospatial science.

This volume addresses the relationship between law and neoliberalism. Assembling work from established and emerging legal scholars, political theorists, philosophers, historians, and sociologists from around the world – including the Americas, Australia, Europe, and the United Kingdom – it addresses the conceptual, legal, and political relationships between liberal legality and neoliberal economics. More specifically, the book analyses the role that legality plays in the dominant economic force of our time, offering both a legal corrective to scholarship in economics and political economy that has paid insufficient attention to legal ideas, and, at the same time, a political economic corrective to legal scholarship that has only recently turned to theorizing neoliberalism. It will be of enormous interest to those working at the intersection of law and politics in our neoliberal age.

The world is facing severe and growing challenges in maintainig water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these chanllenges facing water resources management: and modeling at this scale can provide essential information for policy makers in their decisions on allication of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

Use of un-treated/partially treated wastewater for irrigation in the dry countries of Asia and Africa and recycling of treated wastewater in the water scarce developed countries has become a common practice due to various reasons. While the lack of wastewater treatment to appropriate levels before use is a major problem in developing countries, the high cost of wastewater recycling is the major problem in developed countries. The current paper is part of a doctoral research and presents the conceptual framework for the research and the methodology that can be used to tackle the problems associated with wastewater recycling.

This report develops an integrated economic-hydrologic river basin model and applies it to the Maipo River Basin in central Chile. Policy simulations based on the modeling framework can serve as a guide for water resource managers and policymakers in designing appropriate water policies and establishing reform priorities for water resource allocation. Alternative analyses undertaken for the Maipo basin-a mature water economy with limited resources and competition for water across all water-using sectors-offer new insights into the changing relationships between irrigation system and basin-level water use efficiencies. They also show how these changing relationships affect farm incomes and environmental impacts. Simulations also provide new results on the role that the trading of water use rights can play in maintaining farm production levels, enhancing farmer incomes, and increasing water use efficiencies.
