This book was released on 2023-09-08 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication, Water Quality in Agriculture: Risks and Risk Mitigation, emphasizes technical solutions and good agricultural practices, including risk mitigation measures suitable for the contexts of differently resourced institutions working in rural as well as urban and peri-urban settings in low- and middle-income countries. With a focus on sustainability of the overall land use system, the guidelines also cover possible downstream impacts of farm-level decisions. As each country has a range of site-specific conditions related to climate, soil and water quality, crop type and variety, as well as management options, subnational adjustments to the presented guidelines are recommended. Water Quality in Agriculture: Risks and Risk Mitigation, is intended for use by national and subnational governmental authorities, farm and project managers, extension officers, consultants and engineers to evaluate water quality data, and identify potential problems and solutions related to water quality. The presented guidelines will also be of value to the scientific research community and university students.The chapters in this publication address the following topics:Chapter 2 describes the linkages between water quality and achieving the United Nations Sustainable Development Goals, and the need for water quality monitoring. Chapter 3 provides an overview of existing water quality guidelines and standards across the world, including those reliant on technological advances and stringent water quality monitoring, and others based on health-based targets, as recommended by WHO. Chapter 4 is dedicated to pathogenic threats, in particular from domestic wastewater, while the elaborated Chapter 5 targets chemical risks with significant emphasis on salinity. The interlinkages between water quality and aquaculture and water quality and livestock production are described in Chapters 6 and 7, respectively. The importance of water quality for a healthy environment and ecology is explored in Chapter 8, and further extended to watersheds and river basin scales in Chapter 9, looking at the approaches used to analyze, monitor, and manage water quality, and possible downstream impacts in their larger geographical context. Finally, Chapter 10 provides an overview of the most common and/or significant barriers and drivers of relevance for the adoption of water reuse guidelines and best practices within a given regulatory and institutional context with special attention to low- and middle-income countries.

Task Force 4 - Food Security and Sustainable Agriculture. This book was released on 2022-11-02 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: As urbanization increases, meeting the challenges of urban food supply and food security requires coherent and holistic strategies. Attention too often focuses solely on best practices without addressing the required behavior change. This policy brief highlights the importance of minimizing food loss and waste, which accounts for some 30% of current global production, in order to link and achieve SDGs 2, 11 and 12. The strategy comprises four interrelated elements, namely adopting holistic and circular planning perspectives; facilitating urban and peri-urban farming; integrating innovative behavioral interventions; and providing enabling environments. The G20 has the capacity to act rapidly, without the need for major capital investment, thereby also providing leadership to the entire international community.

Available in PDF, EPUB and Kindle. Book excerpt: This volume provides state-of-the-art information on soil-water interactions in wastewater systems, characterization of wastewater, modes of treatment, safety of wastewater use, water conservation technologies involved in recycling of sewage in fish culture, biogeochemical cycling bacteria and nutrient dynamics, ecosystem resilient driven wastewater reclamation, bioremediation, aquaponics, ecological integrity, culture practices of fish farming, microbial food web phenomena, fish diseases, environmental economics of wastewater, environmental risk assessment, environmental law and regulations. Given its breadth of coverage, the book will be useful to researchers, teachers, students, administrators, planners, farmers and entrepreneurs interested in the profitable use of wastewater in the wastes-into-wealth framework of for the benefit of humanity, and in achieving the targets for sanitation and safe wastewater reuse by 2030, specified in the United Nations’ Sustainable Development Goals. Concerns are growing about the quality and quantity of fresh water, as severe crises are expected in the near future. Climate change has further worsened the strain on inland water resources, with its major impacts on ecosystems and human life. It is most urgent to protect and conserve inland water resources to maintain vital ecosystem functions. Despite the immense nutrient potentials of wastewater in terms of phosphorus, nitrogen and potassium and increasingly high rates of urbanization-based wastewater generation, wastewater has traditionally been overlooked as a resource. This produces a threefold loss – environmental degradation, monetary losses from fertilizers, and water. As a result, municipal wastewater offers a win-win strategy for water conservation and environmental protection, while also turning waste into wealth in the form of fish biomass and allied cash crops. Wastewater-fed aquaculture refers to a unique, integrated biosystem in which the wastes generated by the first system are used by the next subsystem. In wastewater-fed aquaculture biosystems, the organic wastes are recycled into fish biomass mediated through a complex microbial/autotrophic/heterotrophic food web mechanism.

Download or read book The Business of Water and Sustainable Development written by Jonathan Chenoweth and published by Routledge. This book was released on 2018-05-08 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: A renewed commitment to improved provision of water and sanitation emerged in the 2002 Johannesburg Declaration on Sustainable Development. Although many of the statements in the Declaration were vaguely worded, making it hard to measure progress or success, the Plan of Implementation of the Summit, agreed by the delegates to the conference, clearly stated that: "we agree to halve, by the year 2015, the proportion of people who are unable to reach or to afford safe drinking water and the proportion of people who do not have access to basic sanitation". Given the United Nations' predicted growth in global population from 6.1 billion in 2000 to 7.2 billion by 2015, this commitment will pose formidable challenges. To meet it, by the end of just a decade and half, approximately 6.6 billion people will need to have access to safe drinking water supplies. This is more than the current population of the world, and involves not only maintaining existing levels of supply but also providing new or upgraded services to 1.7 billion people. The challenge for sanitation is equally daunting: 5.8 billion people will need to be serviced, including new access provision for 2.1 billion. Even if these ambitious targets are met, representing a major achievement for the global community, there will still be approximately 650 million people in the world without access to safe drinking water and 1.4 billion without sanitation. What is clear is the magnitude of the problem facing the international community in terms of water supply and sanitation. Continuation of the status quo and the type of progress made during the 1990s will not permit the Johannesburg targets to be met. Instead it will be necessary to promote a combination of many different, new and innovative approaches, each of which will contribute towards the overall targets. These approaches must include technological advances that identify new sources and improve the quality of those already in use; managerial techniques that increase the efficiency and effectiveness of service delivery at both micro and macro scale; and fiscal approaches that tap into additional financial resources to make improvements affordable. In the past each of these aspects was seen as primarily the responsibility of government, which supported research into technology, managed supply and disposal systems and provided the funds to pay for them. This view has changed – beginning in the 1980s and increasing in the 1990s with growing moves towards privatisation of many aspects of the water sector. Underpinning this has been a shift away from seeing water as a public good that is essential for life, with subsidised supply provided as part of an overall welfare system, to a more market-oriented approach where the state, although still responsible for maintaining universal access to water services, uses market forces to meet this aim. The Business of Water and Sustainable Development aims to illustrate the range of approaches that will be necessary if the percentage of the global population having access to adequate and safe water and sanitation is to be increased in line with the brave assertions from Johannesburg World Summit on Sustainable Development. Some of approaches will be large-scale "Western-style" improvements involving the creation of new business models, their effectiveness assessed by traditional approaches of fiscal and social analysis. Such schemes may be instigated and partly funded by governments, but are increasingly turning to the private sector for money and expertise. In contrast, many smaller communities would be better served by following another path to improved water supply and sanitation. Because of their size, location or traditions they may achieve better results through the adoption of local small-scale solutions. Non-governmental organisations have been very active in this area, but to extend their operations many are seeking to adopt a more business-like model. All water supply and waste disposal agencies, large or small, need to support and encourage continued research into technological solutions that seek out better, more sustainable ways to use our increasingly scarce supplies of good-quality fresh water.

Download or read book Resource Recovery from Waste written by Miriam Otoo and published by Routledge. This book was released on 2018-03-20 with total page 1257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans generate millions of tons of waste every day. This waste is rich in water, nutrients, energy and organic compounds. Yet waste is not being managed in a way that permits us to derive value from its reuse, whilst millions of farmers struggle with depleted soils and lack of water. This book shows how Resource Recovery and Reuse (RRR) could create livelihoods, enhance food security, support green economies, reduce waste and contribute to cost recovery in the sanitation chain. While many RRR projects fully depend on subsidies and hardly survive their pilot phase, hopeful signs of viable approaches to RRR are emerging around the globe including low- and middle-income countries. These enterprises or projects are tapping into entrepreneurial initiatives and public ̶ private partnerships, leveraging private capital to help realize commercial or social value, shifting the focus from treatment for waste disposal to treatment of waste as a valuable resource for safe reuse. The book provides a compendium of business options for energy, nutrients and water recovery via 24 innovative business models based on an in-depth analysis of over 60 empirical cases, of which 47 from around the world are described and evaluated in a systematic way. The focus is on organic municipal, agro-industrial and food waste, including fecal sludge, supporting a diverse range of business models with potential for large-scale out-and up-scaling.

Available in PDF, EPUB and Kindle. Book excerpt: The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members and 38 Partners to publish The United Nations World Water Development Report, (WWDR) series. The annual World Water Development Reports focus on strategic water issues. UN-Water Members and Partners, all experts in their respective fields, contribute the latest findings on a specific theme. The 2017 edition of the World Water Development Report focuses on 'Wastewater' and seeks to inform decision-makers, inside and outside the water community, about the importance of managing wastewater as an undervalued and sustainable source of water, energy, nutrients and other recoverable by-products, rather than something to be disposed of or a nuisance to be ignored. The report's title - Wastewater: The Untapped Resource - reflects the critical role that wastewater is poised to play in the context of a circular economy, whereby economic development is balanced with the protection of natural resources and environmental sustainability, and where a cleaner and more sustainable economy has a positive effect on the water quality. Improved wastewater management is not only critical to achieving the Sustainable Development Goal on clean water and sanitation (SDG 6), but also to other goals of the 2030 Agenda for Sustainable Development.

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 175 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.

Download or read book Water Reuse written by Chris Binnie and published by IWA Publishing. This book was released on 2008-05-14 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Reuse: An International Survey of current practice, issues and needs examines water reuse practices around the world from different perspectives. The objective is to show how differently wastewater reuse is conceived and practised around the world as well as to present the varied needs and possibilities for reusing wastewater. In the first section water reuse practices around the world are described for regions having common water availability, reuse needs and social aspects. The second section refers to the “stakeholders” point of view. Each reuse purpose demands different water quality, not only to protect health and the environment but also to fulfil the requirements of the specific reuse. Reuses considered are agricultural, urban agriculture as a special case of the former, municipal and industrial. Alongside these uses, the indirect reuse for human consumption through aquifer recharge is also discussed. The third section deals with emerging and controversial topics. Ethical and economical dilemmas in the field are presented as a subject not frequently addressed in this field. The role of governments in respect of public policy in reuse is discussed as well as the different international criteria and standards for reusing wastewater. The importance of public acceptance and the way to properly handle it is also considered. The fourth section of the book presents contrasting case studies; typical situations in the developed world (Japan and Germany) are compared to those in developing countries (Pakistan and Brazil) for agricultural and industrial reuse. Indirect planned reuse for human consumption (Germany) is compared with an unplanned one (Mexico). The Windhoek, Namibia case study is presented to emphasize why if the direct reuse of wastewater for human consumption has been performed with success for more than 35 years it is still the only example of this type around the world. To illustrate the difficulties of having a common framework for regulating water reuse in several countries, the Mediterranean situation is described. Other case studies presented refer to the reuse situation in Israel, Spain, Cameroon, Nepal and Vietnam, these latter countries being located in water rich areas. This book will be an invaluable information source for all those concerned with water reuse including water utility managers, wastewater policy makers and water resources planners as well as researchers and students in environmental engineering, water resources planning and sanitary engineering.

This book was released on 2015-03-23 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members as well as 37 Partners to publish the United Nations World Water Development Report (WWDR) series. Under the theme Water for Sustainable Development, the WWDR 2015 has been prepared as a contribution from UN-Water to the discussions surrounding the post-2015 framework for global sustainable development. Highlighting water's unique and often complex role in achieving various sustainable development objectives, the WWDR 2015 is addressed to policy- and decision-makers inside and outside the water community, as well as to anyone with an interest in freshwater and its many life-giving benefits. The report sets an aspirational yet achievable vision for the future of water towards 2050 by describing how water supports healthy and prosperous human communities, maintains well functioning ecosystems and ecological services, and provides a cornerstone for short and long-term economic development. It provides an overview of the challenges, issues and trends in terms of water resources, their use and water-related services like water supply and sanitation. The report also offers, in a rigorous yet accessible manner, guidance about how to address these challenges and to seize the opportunities that sound water management provides in order to achieve and maintain economic, social and environmental sustainability.

This book was released on 2011-10-20 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: As one of the eighteen field-specific reports comprising the comprehensive scope of the strategic general report of the Chinese Academy of Sciences, this sub-report addresses long-range planning for developing science and technology in the field of agriculture. They each craft a roadmap for their sphere of development to 2050. In their entirety, the general and sub-group reports analyze the evolution and laws governing the development of science and technology, describe the decisive impact of science and technology on the modernization process, predict that the world is on the eve of an impending S&T revolution, and call for China to be fully prepared for this new round of S&T advancement. Based on the detailed study of the demands on S&T innovation in China’s modernization, the reports draw a framework for eight basic and strategic systems of socio-economic development with the support of science and technology, work out China’s S&T roadmaps for the relevant eight basic and strategic systems in line with China’s reality, further detail S&T initiatives of strategic importance to China’s modernization, and provide S&T decision-makers with comprehensive consultations for the development of S&T innovation consistent with China’s reality. Supported by illustrations and tables of data, the reports provide researchers, government officials and entrepreneurs with guidance concerning research directions, the planning process, and investment. Founded in 1949, the Chinese Academy of Sciences is the nation’s highest academic institution in natural sciences. Its major responsibilities are to conduct research in basic and technological sciences, to undertake nationwide integrated surveys on natural resources and ecological environment, to provide the country with scientific data and consultations for government’s decision-making, to undertake government-assigned projects with regard to key S&T problems in the process of socio-economic development, to initiate personnel training, and to promote China’s high-tech enterprises through its active engagement in these areas.
