Book Description
This paper argues that there are many challenges to designing and implementing water and sanitation interventions that actually deliver economic benefits to the households in developing countries. Perhaps most critical to successful water and sanitation investments is to discover and implement forms of service and payment mechanisms that will render the improvements worthwhile for those who must pay for them. In this paper, we argue that, in many cases, the conventional network technologies of water supply and sanitation will fail this test, and that poor households need alternative, non-network technologies. However, it will not necessarily be the case that specific non-network improved water supply and/or sanitation technologies will always be seen as worthwhile by those who must pay for them. We argue that there is no easy panacea to resolve this situation. For any intervention, the outcome is likely to be context-dependent. An intervention that works well in one locality may fail miserably in another. For any given technology, the outcome will depend on economic and social conditions, including how it is implemented, by whom, and often on the extent to which complementary behavioral, institutional and organizational changes also occur. For this reason, we warn against excessive generalization: one cannot, in our view, say that one intervention yields a rate of return of x% while another yields a return of y%, because the economic returns are likely to vary with local circumstances. More important is to identify the circumstances under which an intervention is more or less likely to succeed. Also for this reason, when we analyze a few selected water and sanitation interventions, we employ a probabilistic rather than a deterministic analysis to emphasize that real world outcomes are likely to vary substantially.

Book Description
Environmental engineers support the well-being of people and the planet in areas where the two intersect. Over the decades the field has improved countless lives through innovative systems for delivering water, treating waste, and preventing and remediating pollution in air, water, and soil. These achievements are a testament to the multidisciplinary, pragmatic, systems-oriented approach that characterizes environmental engineering. Environmental Engineering for the 21st Century: Addressing Grand Challenges outlines the crucial role for environmental engineers in this period of dramatic growth and change. The report identifies five pressing challenges of the 21st century that environmental engineers are uniquely poised to help advance: sustainably supply food, water, and energy; curb climate change and adapt to its impacts; design a future without pollution and waste; create efficient, healthy, resilient cities; and foster informed decisions and actions.

Book Description
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.

Book Description
The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each devoted to one of the 17 SDGs. This volume is dedicated to SDG 6 "Ensure availability and sustainable management of water and sanitation for all". Water and sanitation are fundamental to human well-being. Integrated water resources management is essential to ensure availability and sustainable management of water and sanitation for all and to the realization of Sustainable Development. Concretely, the defined targets are: Achieve universal and equitable access to safe and affordable drinking water for all Achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations Improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally Substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity and substantially reduce the number of people suffering from water scarcity Implement integrated water resources management at all levels, including through transboundary cooperation as appropriate Protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lakes Expand international cooperation and capacity-building support to developing countries in water- and sanitation-related activities and programmes, including water harvesting, desalination, water efficiency, wastewater treatment, recycling and reuse technologies Support and strengthen the participation of local communities in improving Uwater and sanitation management Editorial Board Ulisses M.

Book Description
Released every three years since March 2003, the United Nations World Water Development Report (WWDR), a flagship UN-Water report published by UNESCO, has become the voice of the United Nations system in terms of the state, use and management of the world's freshwater resources. The report is primarily targeted at national decision-makers and water resource managers, but is also aimed at educating and informing a broader audience, from governments to the private sector and civil society. It underlines the important roles water plays in all social, economic and environmental decisions, highlighting policy implications across various sectors, from local and municipal to regional and international levels. Similarly to the first two editions, this report includes a comprehensive and up-to-date assessment of several key challenge areas, such as water for food, energy and human health, and governance challenges such as institutional reform, knowledge and capacity-building, and financing, each produced by individual UN agencies.

Book Description
The substantial burden of death and disability that results from interpersonal violence, road traffic injuries, unintentional injuries, occupational health risks, air pollution, climate change, and inadequate water and sanitation falls disproportionally on low- and middle-income countries. Injury Prevention and Environmental Health addresses the risk factors and presents updated data on the burden, as well as economic analyses of platforms and packages for delivering cost-effective and feasible interventions in these settings. The volume's contributors demonstrate that implementation of a range of prevention strategies-presented in an essential package of interventions and policies-could achieve a convergence in death and disability rates that would avert more than 7.5 million deaths a year.

Book Description
As the human population grows-tripling in the past century while, simultaneously, quadrupling its demand for water-Earth's finite freshwater supplies are increasingly strained, and also increasingly contaminated by domestic, agricultural, and industrial wastes. Today, approximately one-third of the world's population lives in areas with scarce water resources. Nearly one billion people currently lack access to an adequate water supply, and more than twice as many lack access to basic sanitation services. It is projected that by 2025 water scarcity will affect nearly two-thirds of all people on the planet. Recognizing that water availability, water quality, and sanitation are fundamental issues underlying infectious disease emergence and spread, the Institute of Medicine held a two-day public workshop, summarized in this volume. Through invited presentations and discussions, participants explored global and local connections between water, sanitation, and health; the spectrum of water-related disease transmission processes as they inform intervention design; lessons learned from water-related disease outbreaks; vulnerabilities in water and sanitation infrastructure in both industrialized and developing countries; and opportunities to improve water and sanitation infrastructure so as to reduce the risk of water-related infectious disease.
