Download or read book Safe Use of Wastewater in Agriculture written by Hiroshan Hettiarachchi and published by Springer. This book was released on 2018-03-09 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.

Book excerpt: Water is the next oil over which nations will fight wars. Severe water shortages already affect some 450 million people living in 29 countries, and analysts have predicted that tensions over water rights in Asia, Africa, and the Middle East could explode into violent clahses and even full-blown wars if governments do not manage existing water supplies more efficiently. Worldwide, 220 river basins are shared by two or more countries and the tensions caused by water scarcity will escalate in this century---the water shortage problems will be exacerbated by global warming and its associated unpredicatable weather patterns. In 2001, the CIA predicted that by 2015, almost half of the world?s population, more than 3 billion people, will live in "water-stressed"countries. How can communities that don't have millions of dollars to hire multinational engineering companies to build highly advanced (but also highly energy and chemical intensive) water- and wastewater-treatment systems? This book is full of practical, low-cost, effective, ecological and economically sustainable, environmental friendly solutions for communities. In the 762 pages (with 185 diagrams and 910 photographs), readers will be introduced to many types of ecologically designed and engineered water- and wastewater-treatment systems, which communities can build with locally available labor, expertise, and resources.

Book excerpt: Natural Water Treatment Systems for Safe and Sustainable Water Supply in the Indian Context is based on the work from the Saph Pani project (Hindi word meaning potable water). The book aims to study and improve natural water treatment systems, such as River Bank Filtration (RBF), Managed Aquifer Recharge (MAR), and wetlands in India, building local and European expertise in this field. The project aims to enhance water resources and water supply, particularly in water stressed urban and peri urban areas in different parts of the Indian sub-continent.

Download or read book Drinking Water Treatment written by Chittaranjan Ray and published by Springer Science & Business Media. This book was released on 2011-06-16 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to “democratize” membrane filtration have been presented. Riverbank filtration is a “natural” filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Field Practices for Wastewater Use in Agriculture discusses the growing importance of wastewater application in the field of agriculture. Addressing the tremendous need for the irrigation sector to reduce the demand for freshwater in agriculture, this volume looks at wastewater as a source for agricultural irrigation. The volume is divided into four sections: current and emerging issues in wastewater use in agriculture, wastewater management with biological systems, effective field practices for wastewater use, and case studies that provide information on scientific analytical studies on the environment under the influence of wastewater quality from different pollution sources. This book sheds light on the vast potential of wastewater use in agricultural irrigation while also considering safety of the agricultural products for human consumption. Much emphasis has also been given to technological aspects for the treatment of wastewater to protect our environment for better public health protection.

Download or read book Innovation Issues in Water Agriculture and Food written by Maria do Rosario Cameira and published by MDPI. This book was released on 2019-07-15 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a worldwide context of ever-growing competition for water and land, climate change, droughts and man-made water scarcity, and less-participatory water governance, agriculture faces the great challenge of producing enough food for a continually increasing population. In this line, this book provides a broad overview of innovation issues in the complex water–agriculture–food nexus, thus also relative to their interconnections and dependences. Issues refer to different spatial scales, from the field or the farm to the irrigation system or the river basin. Multidisciplinary approaches are used when analyzing the relationships between water, agriculture, and food security. The covered issues are quite diverse and include: innovation in crop evapotranspiration, crop coefficients and modeling; updates in research relative to crop water use and saving; irrigation scheduling and systems design; simulation models to support water and agricultural decisions; issues to cope with water scarcity and climate change; advances in water resource quality and sustainable uses; new tools for mapping and use of remote sensing information; and fostering a participative and inclusive governance of water for food security and population welfare. This book brings together a variety of contributions by leading international experts, professionals, and scholars in those diverse fields. It represents a major synthesis and state-of-the-art on various subjects, thus providing a valuable and updated resource for all researchers, professionals, policymakers, and post-graduate students interested in the complex world of the water–agriculture–food nexus.
