    Uncertainty in Wastewater Treatment Design and Operation Addressing Current Practices and Future Directions

    1-234页
    查看更多>>摘要:The International Water Association (IWA) Design and Operations Uncertainty Task Group (DOUT) wasformed to develop methodologies that enable the explicit evaluation of variability and uncertainty in modelbaseddesign of water resource recovery facilities (WRRF), and model-based analysis of plant operations.An overview of uncertainty in the treatment plant modelling context was discussed at a workshop (inMont-Sainte-Anne, Canada) during the 1st IWA/WEF (Water Environment Federation) WastewaterTreatment Modelling seminar (WWTmod2008). This workshop identified knowledge gaps and therequirements for the development of the needed methodologies. Following the workshop, the TaskGroup established the following set of objectives and set-up several working groups to advance these goals:1. Document how uncertainty and risk are currently handled in wastewater treatment practice byconsultants, utilities and regulators.

    Resilience of Water Supply in Practice: Experiences from the Frontline

    1-210页
    查看更多>>摘要:This book aims to highlight the challenges in water supply that are faced in a range oflocations, from industrialized, to fragile and conflict affected, and low- and middle-incomecountries. Water supplies globally are at risk from both slow and rapid onset threats. As aresult, services need to become more resilient and those working on the frontline, moreprepared to respond to threats rapidly. This book describes the different ways in whichwater suppliers respond to the challenges faced.

    Implementing the Water–Energy–Food–EcosystemsNexus and Achieving the Sustainable Development Goals

    1-210页
    查看更多>>摘要:Natural resources are increasingly at risk due to climate change, demographic pressure and economic growth, politicalinstability, and forced migration. Globalization places additional strain on the resources, biodiversity, and ecosystemsand, through them, on the economies and well-being of populations of both affected and neighbouring countries. Amongthe greatest challenges to economic and social development and cooperation are the identification of appropriate andtimely adaptation measures in this continuously changing environment. Equally important are the multi-sectorialinterlinkages towards achieving the sustainable development goals (SDGs), Paris Agreement targets, the SendaiFramework for Disaster Risk Reduction, the EU Green Deal and emerging challenges such as the coronavirusdisease (COVID) crisis.

    The Cultural Dynamics in Water Management from Ancient History to the Present Age

    1-277页
    查看更多>>摘要:Since water is comprehensively connected with human society, diversified way ofthinking, using, and managing water have developed. This has led to thediversification of water culture worldwide. Water culture was generated fromwater management, the social demand, and the spiritual feel of water.Consequently, it has also influenced water management comprehensivelybeginning from the earliest times to the present age. People worldwide rely ontheir own ideas, values, social relationships, institutions, and religion to managewater. This, however, has made water culture an important dynamic in watermanagement and has also made water management acceptable, effective, equal,and sustainable. Water culture also deeply influences the spiritual world andsocial life of mankind. Water culture has a structural make up involving thelevels of ideas, institutions, social life, and physical factors and is based on theattributes of nationality, civilization, local, and times. This theoretical structureand attributes provide a better understanding of water culture based on scientificand holistic dimension. Meanwhile, a dynamics mechanism was modeled asDouble Dynamics and Bidirectional Dynamics to explain the relationshipbetween water and mankind so as to better understand how the culturalgeneration is driven by water and the cultural initiative in water management.This chapter aims to build the structure and define the types of water culture, toexploring the dynamic mechanism of water culture in water management andhuman society, and to understand the generation and formation of water culture.

    A Guide to Understanding the Fundamental Principles of Environmental Management

    1-226页
    查看更多>>摘要:Technological innovation, which has given humans dominance over land and waterand made once scarce resources readily available, is a two-edged sword: it has freedmuch of humanity from the shackles of food and resource scarcity, but it does so atthe cost of environmental degradation. The latter comes, ironically, from excesses ofwhat makes life possible.The research that I and my fellow scientists conduct documents the adverseimpacts of ill-management of natural resources and illuminates solutions to thedilemma. Nevertheless, if progress towards sustainability is to be achieved, thescience must be translated into action. In other words, managing and protectingthe environment means making decisions on how resources are used. Not alldecisions are alike. We naturally want the action to solve the problems we face,but the likelihood that it does so depends substantially upon how well theproblem has been defined and the appropriateness of the response. There is no setscript to guide actions for the manager to follow. Scientific knowledge is everevolving in the context of ever-changing human demands on natural resourcesmade ever more complicated within a changing climate. The successful managermust know how to construct responses to these difficult challenges on soundscientific principles. He or she must know or anticipate, as if instinctively, wherethe sword will slice, and how to seek appropriate scientific guidance.

The book was well received in a largenumber of countries.However, there have been many changes on our planet in the past 12 years. Global population continuesto grow, but while it is virtually exploding in some parts of the world, it is declining elsewhere. This ishaving a major impact on the global economy and, consequently, on macro geopolitics. Stability appearsto be on the downslope. People are migrating, largely because of wars but also due to major economicand political disparities. Climate and climate change are part of the counterpoint. While my associatesand I are finalizing this book, the COVID-19 pandemic is a threat to the global population and economy.

    查看更多>>摘要:Se están reescribiendo las normas de calidad del agua en todo el mundo para promoverecosistemas más sanos, garantizar fuentes de agua potable segura, aumentar la biodiversidady mejorar las funciones ecológicas. Los humedales para tratamiento se utilizan para tratar unavariedad de aguas contaminantes, incluidas las aguas residuales municipales, la escorrentíaagrícola y urbana, los efluentes industriales y los desbordamientos de las alcantarillascombinadas, entre otros. Los humedales para tratamiento son particularmente adecuados parala gestión sostenible del agua porque pueden hacer frente a cargas variables del influente,pueden ser construidos con materiales locales, tienen bajos requerimientos de operación ymantenimiento en comparación con otras tecnologías de tratamiento, y pueden proporcionarservicios adicionales de ecosistema. Esta tecnología se ha aplicado con éxito tanto en los paísesdesarrollados como en los países en desarrollo.

    查看更多>>摘要:Since 2015, with the adoption of the SustainableDevelopment Goals (SDGs) by the United Nations(UN), the importance of non-sewered sanitationservice provision and the major inequalities ofsanitation service delivery have been highlighted. In2017 the Joint Monitoring Program (JMP) of the UNand the World Health Organisation (WHO) estimatedthat around 4.2 billion people, or 55% of the globalpopulation, did not have access to safely managedsanitation. This is the equivalent of 6 people out of 10,with the vast majority living in developing countries,in communities where sewer-based approaches are notfeasible, practical, or too expensive.
