Download or read book Urban wastewater Reuse for Crop Production in the Water short Guanajuato River Basin Mexico written by Christopher Anand Scott and published by IWMI. This book was released on 2000 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a river-basin perspective, wastewater irrigation is an important form of water and nutrient reuse; however, there are important water quality, environmental, and public health considerations. This report explores the advantages and risks of urban wastewater reuse for crop production in the water-short Guanajuato river-basin in west-central Mexico, and then by a selective literature review demonstrates how common this practice is worldwide. It also evaluates several alternative water-management scenarios through application of the Interactive River Aquifer Simulation (IRAS) model, developed by Cornell University and Resource Planning Associates.
Download or read book Water Centric Sustainable Communities written by Vladimir Novotny and published by John Wiley & Sons. This book was released on 2010-09-23 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current literature compartmentalizes the complex issue of water and wastewater into its discrete components; technology, planning, policy, construction, economics, etc. Considered from the perspective of sustainability, however, water in the urban environment must be approached as a single resource that can be continuously reused and recycled. This book will be the first to capture all of the current work on this idea in a single, integrated, plan for designing the water-centric cities of the future. From new construction to the retrofitting of existing systems, this book presents the case for a new urban relationship to water, one with a more sustainable connection to the environment and the hydrological cycle. Through case studies of successfully planned and built systems around the world, the book will educate the reader about the need for a new approach to urban water management, and make the case that these changes are not only possible but imperative.
Download or read book Routledge Handbook of Landscape and Food written by Joshua Zeunert and published by Routledge. This book was released on 2018-02-02 with total page 799 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the turn of the millennium, there has been a burgeoning interest in, and literature of, both landscape studies and food studies. Landscape describes places as relationships and processes. Landscapes create people’s identities and guide their actions and their preferences, while at the same time are shaped by the actions and forces of people. Food, as currency, medium, and sustenance, is a fundamental part of those landscape relationships. This volume brings together over fifty contributors from around the world in forty profoundly interdisciplinary chapters. Chapter authors represent an astonishing range of disciplines, from agronomy, anthropology, archaeology, conservation, countryside management, cultural studies, ecology, ethics, geography, heritage studies, landscape architecture, landscape management and planning, literature, urban design and architecture. Both food studies and landscape studies defy comprehension from the perspective of a single discipline, and thus such a range is both necessary and enriching. The Routledge Handbook of Landscape and Food is intended as a first port of call for scholars and researchers seeking to undertake new work at the many intersections of landscape and food. Each chapter provides an authoritative overview, a broad range of pertinent readings and references, and seeks to identify areas where new research is needed—though these may also be identified in the many fertile areas in which subjects and chapters overlap within the book.
Download or read book The Water Food Energy and Climate Nexus written by Felix Dodds and published by Routledge. This book was released on 2016-03-31 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global trends of population growth, rising living standards and the rapidly increasing urbanized world are increasing the demand on water, food and energy. Added to this is the growing threat of climate change which will have huge impacts on water and food availability. It is increasingly clear that there is no place in an interlinked world for isolated solutions aimed at just one sector. In recent years the "nexus" has emerged as a powerful concept to capture these inter-linkages of resources and is now a key feature of policy-making. This book is one of the first to provide a broad overview of both the science behind the nexus and the implications for policies and sustainable development. It brings together contributions by leading intergovernmental and governmental officials, industry, scientists and other stakeholder thinkers who are working to develop the approaches to the Nexus of water-food-energy and climate. It represents a major synthesis and state-of-the-art assessment of the Nexus by major players, in light of the adoption by the United Nations of the new Sustainable Development Goals and Targets in 2015.

Download or read book Valuing Water in Irrigated Agriculture and Reservoir Fisheries written by Mary E. Renwick and published by IWMI. This book was released on 2001 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although irrigation projects often provide water for more than crop irrigation, water allocation and management decisions often do not account for nonirrigation uses of water. Failure to account for the multiple uses of irrigation water may result in inefficient and inequitable water allocation decisions. Decision-makers often lack information on the relative economic contributions of water in irrigation and nonirrigation uses. This report addresses this problem. It examines the relative economic contributions of irrigated agriculture and reservoir fisheries in the Kirindi Oya irrigation system, located in Southeastern Sri Lanka. The results of the analysis indicate the importance of both irrigated paddy production and reservoir fisheries to the local economy. They also demonstrate significant potential financial and economic gains to irrigated agriculture from improvements in water management practices. Since these water uses are interdependent, policy makers must consider how changes in water management practices may affect reservoir levels and water quality and the fisheries that depend on them.

Download or read book Governance of Urban Wastewater Reuse for Agriculture written by Ganesh Keremane and published by Springer. This book was released on 2017-05-09 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a conceptual and practical tool for those involved directly or indirectly in the planning and management of basic provision of water supply, wastewater and stormwater services in metropolitan regions by offering insights into governance paradigms and institutional arrangements for urban wastewater reuse in agriculture from Australia and India. Instead of focusing on the technical aspects of designing and building infrastructure, it provides a better understanding of the institutional and governance challenges of managing urban wastewater, particularly for reuse in agriculture. As water supplies fall and water stress increases in many areas, the potential of wastewater as a resource is being widely recognized. Today, wastewater (re)use has become an attractive option for conserving and expanding available water supplies. While wastewater (re)use can have many applications, its use in agriculture is the most established, and the one with the longest tradition. Given the growing competition for freshwater from industry and cities, without doubt there is going to be a rapid increase in the global use of treated wastewater, making improved wastewater use in agriculture an emerging priority. Even though it is a vast resource if we reclaim it properly, often most wastewater is wasted. Therefore, in order to realize the full potential of this resource, decision support in policy design and implementation (Institutions and Governance) is key. Institutions and governance frameworks need to provide for the rights of access, rights of ownership, rights to manage source and treated water and the obligations of final use of recycling operations.
Download or read book Estimating Productivity of Water at Different Spatial Scales Using Simulation Modeling written by Peter Droogers and published by IWMI. This book was released on 2001 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.
Download or read book Resources Services and Risks written by Mathew Kurian and published by Springer. This book was released on 2016-01-11 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the role of observatories in supporting evidence-based decision-making. The book focuses on issues of data accessibility, monitoring frameworks and governance processes with regard to environmental resources – water, soil and waste. This publication highlights challenges related to policy-implementation measures and examines current monitoring approaches, and illustrates how the UNU-FLORES Nexus Observatory seeks to overcome concerns related to data, monitoring and governance of water, soil and waste resources. In particular, given that extreme weather events such as droughts and floods are predicted to become more frequent in the future, it discusses the need for improved hazard risk monitoring. It proposes risk indices for drought and floods, which measure exposure and vulnerability to the phenomena through a multitude of bio-physical, socio-economic and institutional indicators. Furthermore, the potential for using openly accessible data made available through observatories in decision-making aimed at improving food security is also discussed. It acknowledges governments as key players in environmental resource management, and recognizes that decentralization reforms, as well as the emergence of information and communication technologies, have significantly changed the role of governments in promoting sustainable development. The book is particularly relevant for decision-makers, donor agencies, practitioners and students with an interest in environmental management who are also keen followers of discussions on the post-2015 monitoring agenda.

The study attempted to answer questions such as; what will happen to the basin water resources if a) there is a change in climate; b) it is decided that more water must be retained in the river for environmental reasons; c) more water is extracted for urban and industrial use; d) the timing and accounts used for water are changed?
Download or read book Water and Sustainability in Arid Regions written by Graciela Schneier-Madanes and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: International voices fill the pages of Water and Sustainability in Arid Regions, forming an original scientific exploration of current water research and management issues. In arid regions, agriculture that is ill-adapted to the environment, accelerated urbanization, poverty, and increasing pollution challenge access to and uses of water. Understanding these issues requires incorporating findings from both the physical and social sciences at different temporal and spatial scales. The chapters in this book were written by hydrologists, remote sensing specialists, ecologists, historians, economists, political scientists, architects, archaeologists, and other experts who live in and study arid lands. The authors present updates, overviews, and analyses of water challenges these areas have faced and are striving to address, from salinization in the fabled Taklimakan Desert in China to land degradation in the northern Mediterranean to groundwater over-exploitation in the southwestern United States. The book also examines desertification, remote sensing, qanat systems, architecture, arsenic contamination, and other case studies from Iran, the Maghreb region, Argentina and Chile, and Mexico. From this conceptual mosaic of comparative perspectives and research methods emerges a strong assumption: an interdisciplinary approach that combines physical and social sciences is the first step toward globally and comprehensively addressing water and sustainability."This book is a valuable and welcome contribution to the discussion of water and sustainable development. Through the collection of chapters, the book clearly illustrates the contemporary diversity of approaches to water scarcity and presents pertinent and new research findings that readers generally do not find compiled together. The result is a highly relevant, accessible, and timely resource that is unique in its international and interdisciplinary content. This is a must-read for anyone working on environmental and sustainability issues in arid lands."André Mariotti, University Pierre et Marie Curie, and INSU - CNRS (National Institute for Earth Sciences and Astronomy-National Center for Scientific Research/Centre National de la Recherche Scientifique), France "Anyone who reads this book will find himself or herself contemplating the need to rethink how we approach the issue of water and sustainability in arid lands. Drawing on the expertise of both physical and social scientists, the chapters taken as a whole present global, historic, and current perspectives on water scarcity in a multi-layered way that rarely has been done before."

Download or read book Wells and Welfare in the Ganga Basin written by Tushaar Shah and published by IWMI. This book was released on 2001 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report analyzes the history of groundwater development in the eastern Uttar Pradesh region over the 1950-1990 period. Its main conclusion is that the story of groundwater-based livelihood creation in the Ganga basin is one of failed public initiatives and successful adaptive responses by private agents. However, tube-well-induced agrarian dynamism in eastern Uttar Pradesh and north Bihar in recent years can spread to the entire basin if public policy makers learn correct lessons from the experience of these two subregions.

Download or read book Charging for Irrigation Water written by C. J. Perry and published by IWMI. This book was released on 2001 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: nadequate funding for maintenance of irrigation works and emerging shortages of water are prevalent. The use of water charges to generate resources for maintenance and to reduce demand is widely advocated. Examples from other utilities, and from the domestic/industrial sectors of water supply suggest the approach could be effective. In developing countries, the facilities required for measured and controlled delivery of irrigation are rarely in place, and would require a massive investment in physical, legal and administrative infrastructure. To be effective in curtailing demand, the marginal price of water must be significant. The price levels required to cover operation and maintenance (O&M) costs are too low to have a substantial impact on demand, much less to actually bring supply and demand into balance. On the other hand, the prices required to control demand are unlikely to be within the politically feasible range. Furthermore, water supplied is a proper measure of service in domestic and industrial uses. But in irrigation, and especially as the water resource itself becomes constrained, water consumption is the appropriate unit for water accounting. This is exceptionally difficult to measure. An alternative approach to cope with shortage would focus on assigning volumes to specific uses–effectively rationing water where demand exceeds supply. This approach has a number of potential benefits including simplicity, transparency, and the potential to tailor allocations specifically to hydrological situations, particularly where salinity is a problem. Data from Iran are presented to support these contentions.
