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 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.
Download or read book Water quality in agriculture Risks and risk mitigation written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. 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: Aquaculture the farming of fish and aquatic plants has become the world's fastest-growing food production sector, even as the amount of wild fish caught in our seas and freshwaters declines. From fish foods and pharmaceuticals to management of entire aquatic ecosystems, acquaculture is truly changing the face of the waters. Increased growth, however, brings increased risk, and aquaculture now lies at a crossroads. One direction points toward the giant strides in productivity, industry concentration, and product diversification. Another direction points toward the dangers of environmental degradation and the marginalization of small fish farmers. Yet another direction invites aquaculture to champion the poor and provide vital environmental services to stressed aquatic environments. 'Changing the Face of the Waters' offers a cutting-edge analysis of the critical challenges facing aquaculture, balancing aquaculture's role in economic growth with the need for sound management of natural resources. The book also provides guidance on sustainable aquaculture by evaluating alternative development pathways, placing particular emphasis on the application of lessons from Asia to Sub-Saharan Africa and Latin America. Aimed at policy makers, planners, and scientists, this book provides a comprehensive frame of reference for orienting ideas and initiatives in this dynamic industry.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The examination of Aquaponics as an urban business model is an analysis of alternative means of producing food in a world facing many sustainability related issues. The planet's population has exponentially grown over the last 60 years from roughly 2.5 billion people in 1950 to just over 7.0 billion people today and is expected to reach 9.0 billion people by 2050. It is expected that the people of the Earth will need 50% more food and 30% more clean water in the next 30 years despite over feeding a billion and underfeeding a billion people (Beddington, 2009). The current Earth has depleted soil, mineral and water resources and is running out of inexpensive energy sources (Brown, 2012). This examination explores the option of using technology coupled with an understanding of natural systems to create a food system that can produce both protein and vegetable produce while limiting water use and eliminating the use of soil and other natural resources. The very nature of this system provides answers to some of our urban social ills, remediation of depleted environmental resources and a profitable and sustainable means of producing food for the long term. The use of recirculating aquaculture systems (RAS) as a system to grow fish intensively, coupled with hydroponics to grow organic produce and serve as the system bio-filter, also known as Aquaponics is ecoming more prevalent. This system has the advantage of being located anywhere, including regions with little water and on small parcels of land either indoors or outdoors. This characteristic serves the unique advantage of allowing this system to be located near or in a city, putting its products in close proximity to its market for consumption. The ability to grow food intensively on a small amount of land in the market area allows the organization to keep the cost of marketing and distribution at lower levels than organizations with rural or international locations and distant markets. The system has the advantage of recycling water, limiting the need for additional water, and using that water as fertilizer to grow high value products. Wastes can be eliminated or mitigated and turned into value-added products that can be sold to a growing market while maintaining a low cost intensive fish and organic produce manufacturing facility. The advantages of this model offer not only the opportunity for a profitable business model but for a model that can be beneficial to the community it serves. Locating food producing businesses within the market they serve has the dual benefit of improving that community's resiliency against increasing food costs brought on by higher environmental, failing farm lands and transportation as well as providing economic development benefits to the community. This thesis examined recirculating aquaculture systems coupled with hydroponics to determine their use as a viable business model in an urban context. The method of analysis included a review of available literature, an online survey and phone interviews of organizations that have employed aquaculture and a complete financial analysis of aquaponics as a commercial application. The results demonstrate that the solution is viable from the perspective that it is possible to utilize these systems to grow fish and produce sustainably. However, survey results were limited by the size of the sample and the quality of the data collected. Essentially the size of the response limited the ability to conclude sustainable economic viability. The financial analysis did demonstrate that these systems can be financially viable if well managed. However, the systems can fail economically if solutions to energy and feed problems are not found. Ultimately, aquaponics will be among the food system solution set. The upside potential of the system from an environmental resource and geographic standpoint demonstrate promise where current systems are still depleting earth resources. Finding sustainable solutions to these problems is an imperative that must be met for the future and aquaponics does solve many of these issues.
