This is a fully revised new edition of this acclaimed practical manual.Indispensable for fieldworkers on projects or programs aiming to reduce the incidence of water-and-sanitation-related diseases, this book will also be useful for other relief and development workers, particularly those working in the fields of community development, health, and engineering.The authors describe a wide range of approaches to hygiene promotion that can be used in different settings. Central to these approaches is a commitment to working in collaboration with people and encouraging them to take more control over the factors that influence their lives. The authors stress the need for a form of hygiene promotion that fosters capacity-building rather than the provision of information alone.The opening chapter of the manual introduces the reader to the context of emergency relief and development projects and provides insights into current hygiene promotion theory. The main body of the text then goes on to consider the four phases of the project cycle--assessment, planning, implementation, and monitoring and evaluation--each of which is assigned a chapter for discussion. These chapters draw together the experience of hygiene promotion fieldworkers in many emergency and rehabilitation, water, sanitation, and hygiene program undertaken by CARE and other agencies. The annex comprises other useful material including a series of concise "how-to" guides, pictures for use or adaptation in the field, information about hygiene-related diseases and how to prevent them, and an annotated bibliography.

Management of sludge is one of the most pressing issues in sanitation provision. The situation is especially complex when large quantities of fresh sludge containing various contaminants are generated in onsite sanitation systems in urban slums, emergency settlements and wastewater treatment facilities that require proper disposal of the sludge. The application of fast and efficient sludge management methods is important under these conditions. This study focused on the development of an innovative sludge treatment unit that is based on the microwave irradiation technology. The technology provides a rapid and efficient option for sludge treatment in isolated conditions such as slum, emergency, and similar situations. The microwave based technology forms part of the eSOS (emergency sanitation operation system) concept that promotes an integrated sanitation approach in which all components of the entire sanitation chain are planned holistically. Besides, the study addresses the deficiencies associated with the poor choice of emergency sanitation technology options by proposing a methodology that is based on compensatory multi-criteria analysis. This study contributes in providing solutions towards improved sanitation in complex scenarios, especially the management of faecal sludge in emergency and slum conditions.
