In the summer of 1999, an international group of experts convened in Jerusalem, Israel, in order to define the major environmental challenges facing humanity at the dawn of the new millennium and - where possible - propose ways of addressing them. Almost 50 selected articles are collected in the present book, which constitutes a striking interdisciplinary combination of state-of-the-art science with the latest views on environmental law, education, and international cooperation. Whilst a major fraction of the book is devoted to water-related issues (water quality monitoring, water and wastewater treatment, water-based international cooperation, and more), other sections deal with timely topics relating to air pollution, biodiversity, conservation, and education. The book is intended for environmental scientists, professionals, and students of all disciplines.

Urban sanitation and solid waste sectors are under significant pressure in East Africa due to the lack of competent institutional capacity and the growth of the region's urban population. This book presents and applies an original analytical approach to assess the existing socio-technical mixtures of waste and sanitation systems and to ensure wider access, increase flexibility and ecological sustainability. It shows how the problem is not the current diversity in waste and sanitation infrastructures and services and variety of types and scales of technology, of formal and informal sector involvement, and of management and ownership modes. The book focuses instead on the lack of an integrative approach to managing and upgrading of the various waste and sanitation configurations and services so as to ensure wider access, flexibility and sustainability for the low income populations who happen to be the main stakeholders. This approach, coined "Modernized Mixtures", serves as a nexus throughout the book. The empirical core addresses the waste and sanitation challenges and debates at each scale - from the micro-level (households) to the macro-level (international support) - and is based on the results of a five-year-long interdisciplinary, empirical research program. It assesses the socio-technical diversity in waste and sanitation and provides viable solutions to sanitation and waste management in East Africa. This book provides students, researchers and professional in environmental technology, sociology, management and urban planning with an integrated analytical perspective on centralized and decentralized waste and sanitation configurations and tools for improvement in the technology, policy and management of sanitation and solid waste sectors.

This monograph is aimed at the practising hydraulic engineer. Work on it commenced at Professor Naudascher's instigation in 1982. Over the next six years all or some of the authors discussed progress at IAHR sponsored conferences at Esslingen, Melbourne, Lausanne and Beijing. With the authors scattered throughout the world, and all with other responsibilities, progress was bound to be slow. Completion was further delayed by the great increase in published technical literature in this area over the period 1982-1988. This literature continues to expand and with it our understanding of the air water flow phenomena. The monograph must therefore be seen as the authors' views on the state of the art around 1988. More recent references have been included for completeness.

This monograph has been a joint effort with most authors making suggestions and contributions to more than one chapter. Nevertheless, the chapter authors are primarily responsible for the material in their chapters.

Throughout the monograph symbols are defined when they are fist introduced and a list of symbols is included at the end of each chapter.

Many other people have contributed to this monograph, but the authors would particularly like to acknowledge the assistance given by Professor John McNown who has read, commented on and improved the style of the complete monograph.

Popular belief holds that throwing the contents of a chamber pot into the street was a common occurrence during the early modern period. This book challenges this deeply entrenched stereotypical image as the majority of urban inhabitants and their local governors alike valued clean outdoor public spaces, vesting interest in keeping the areas in which they lived and worked clean. Taking an extensive tour of over thirty towns and cities across early modern Britain, focusing on Edinburgh and York as in-depth case studies, this book sheds light on the complex relationship between how governors organised street cleaning, managed waste disposal and regulated the cleanliness of the outdoor environment, top-down, and how typical urban inhabitants self-regulated their neighbourhoods, bottom-up. The urban-rural manure trade, sanitation infrastructure, waste-disposal technology, plague epidemics, contemporary understandings of malodours and miasmatic disease transmission and urban agriculture are also analysed. This book will enable undergraduates, postgraduates and established academics to deepen their understanding of daily life and sensory experiences in the early modern British town. This innovative work will appeal to social, cultural and legal historians as well as researchers of history of medicine and public health.

Grasp the Essential Principles of Membrane Bioreactor Processes Evolved from the conventional activated sludge (CAS) process, membrane bioreactor (MBR) processes have become the next-generation solution for municipal and industrial wastewater treatment and recycle. Membrane Bioreactor Processes: Principles and Applications explores nearly all the theoretical and practical aspects of membrane bioreactor technologies. Using the author's expertise obtained from academia and industry, this book provides the crucial details on MBR technology that that you need to know. The book details the theoretical and practical backgrounds of current practices involved with membrane module design, biological and membrane system design, system optimization, and system operation. Outlines the State of the Art of the Membrane Bioreactor Technology The text discusses the fundamentals of membrane filtration, emphasizing the principles of submerged membrane filtration. It also explores the complex interaction among key design and operating parameters, offers comprehensive explanations on the interconnectivity between biological and membrane systems, and covers new findings discovered in recent years. This book clearly explains how small-scale systems perform differently from larger-scale systems and its implications in data interpretation. Using this book as a platform, the technology can be developed further and quickly applied in future processes.

Modern Irrigation Technologies reviews the experience of small holders with irrigation technologies under a range of diverse conditions in many different countries. Some people argue that modern irrigation technologies are the key to increased food production. However, projects introducing modern irrigation technologies in the developing world have often failed because the irrigation hardware, which has been developed for high-technology commercial agriculture, cannot be easily adapted for the use of the smallholder. The author identifies the pre-conditions relating to water availability, institutional support and economic opportunity that must be satisfied before small holders in developing countries can adopt irrigation methods and benefit from them. The circumstances in which modern technologies have been introduced are identified, and the relative success or otherwise of the initiatives are summarized. The book also contains a practical review of the range of irrigation hardware that is available and indicates the types of equipment that are more likely to meet the requirements of the smallholder sector. Modern Irrigation Technologies will be an invaluable guide to project workers, planners and small holders involved in planning and designing irrigation projects.

The modern definition of firefighter no longer means "putting the wet stuff on the red stuff." Emergency responders answer incidents ranging from fire alarm activations to elevator rescues and medical emergencies more often than full-blown fires. Consequently, responders increasingly interface with a wide array of building systems. Underscoring the changing role of firefighters, Fire Protection: Systems and Response presents the basic knowledge of the inner workings of fire safety/fire protection systems and related equipment in buildings.

The author provides a straightforward overview of the functions and benefits of these systems and how they can assist with fire suppression, code enforcement, alarm response, and elevator rescue. The book's comprehensive discussion of elevators, fire command centers, emergency generators and lighting, and HVAC systems sets it apart from other fire protection books currently available. The topics covered prepare emergency response personnel for the challenges they face working with fire protection systems, fire alarm systems, and elevators.

Logically organized, clearly written, and covering all systems in a single text, this presentation of information streamlines fire service interaction with building features and fire protection systems. Providing an understanding of how systems are designed and installed, the book is also a reference for troubleshooting fire protection problems in the field. The information not only gives responders an appreciationknowledge of how the systems work, but helps them use this knowledge to perform their job better.

Originally written for the construction of gravity-flow drinking water systems in Nepal, this book is equally applicable for other locations around the world. Organized for quick reference, it is quickly and easily understood.

Millions of slum residents across the world suffer the hazards and misery of frequent flooding of their streets and homes, which may result in the savings of a lifetime being washed away in a few hours, damaged property, loss of work and time, and higher risks of diarrhea, worm infection, and other health problems. This manual is written to help engineers, aid, and agency workers more clearly to understand drainage problems in the developing world, so that they can work towards finding practical solutions. It focuses on three questions of particular relevance to low-income urban areas in developing countries: What is drainage performance? How can we evaluate a drainage system to improve its performance? What are the effects of solids on the performance of drains? This manual is the outcome of two-and-a-half years of fieldwork in the city of Indore, in Madhya Pradesh, India and can be used as a practical aid by municipal engineers, consulting engineers, and engineering instructors and students, as well as development and aid workers involved in drainage systems.

This book is written for engineers, students of coastal processes and laypersons interested in beach nourishment, which consists of the placement of large quantities of good quality sediment on the beach to advance the shoreline seaward. The improvement of project performance through proper design and the predictability of performance are emphasized. The overall longevity of a project is addressed as are local erosional areas. The roles which wave height, project length and sediment quality play in project performance are addressed quantitatively. The results are illustrated through reference to a number of monitored nourishment projects. Biological and economic aspects of beach nourishment are addressed.

This highly technical work is at the leading edge of spatial analysis. It covers the Global Monitoring for Environment and Security (GMES) initiative in the international context of access to environmental data. This book identifies the data policy issues, such as intellectual property rights, privacy, licensing and archiving policies, that affect environmental monitoring organisations, statistical institutes, mapping agencies, institutes for natural resources and Earth observation. It recommends courses of action to improve information services in GMES and assesses the impact of data policy on access to and cost-efficient use of information services in GMES.

This title will be essential reading for government institutions such as mapping organisations, space agencies, environmental departments, military and defence departments; it will also be useful to students of environmental policies and industries involved in mapping, cartography, aerial surveys and the space industry.
