The Sanitation Triangle: Socio-Culture, Health and Materials

This open access book deals with global sanitation, where SDG 6.2 sets a target of enabling access to sanitation services for all, but has not yet been achieved in low- and middle-income countries. The transition from the United Nations MDGs to the SDGs requires more consideration based on the socio-cultural aspects of global sanitation. In other words, equitable sanitation for those in vulnerable situations could be based on socio-cultural contexts. Sanitation is a system that comprises not only a latrine but also the works for the treatment and disposal of human waste. Sanitation systems do not function by themselves but have significance only through social management. The process of decision-making also largely depends on socio-cultural conditions, and the importance of sanitation needs to be socially acknowledged. The health benefits of sanitation improvement--among the significant contributions of sanitation--also need to be considered in the socio-cultural milieu. Further, the social-culture itself is affected, and potentially even created, by sanitation. In this context, more progress on the improvement of sanitation requires a more holistic approach across disciplines.
In this book, we present the concept of the Sanitation Triangle, which considers the interconnections of health, materials, and socio-culture in sanitation, as a holistic approach, and the case studies based on the Sanitation Triangle by diverse disciplines such as Cultural Anthropology, Development Studies, Health Sciences, Engineering, and Science Communication. By the deep theoretical examinations and inter-dialogues between the different disciplines, this book explores the potentialities of inter-disciplinary studies on global sanitation.

Prof. Taro Yamauchi is a professor at the Research Institute for Humanity and Nature, and the Faculty of Health Sciences, Hokkaido University. He has a B.S., a M.S. and a Ph.D. in Health Sciences from the University of Tokyo. He does intensive fieldwork in hunter-gatherer society, rural villages, and urban slums in developing countries to understand the lifestyle and health of local populations and adaptation to living environments. His research interests also include sanitation and participatory action research involving local children, youth and adults. He is Vice-President of the International Association of Physiological Anthropology (IAPA) and an executive member of the International Society for the Study of Human Growth and Clinical Auxology (ISGA).
Dr. Seiji Nakao is an assistant professor at the Graduate School of Asian and African Area Studies, Kyoto University. He has an M.S. and Ph.D. in Anthropology at Nanzan University. He does fieldwork and archival work in the Francophone West African countries, especially Burkina Faso and Mali for the history of Islam, politics, and economy of Inland West Africa to grasp the modernity in terms of the longue durée. He also engages in interdisciplinary collaborations with engineering, architecture, contemporary art, and science communication, and makes up the auto-ethnographies on these collaborations which happen the (dis)communications between different disciplines from the point of Anthropology of Science and Technology. He is Deputy editor-in-chief of Sanitation Value Chain (SVC) and on the editorial boards of African Study Monographs (ASM).
Dr. Hidenori Harada is an associate professor in the Graduate School of Asian and African Area Studies, Kyoto University, Japan. He received a doctoral and a master’s degree in global environmental studies from Kyoto University, and also a bachelor of engineering (environmental engineering) degree from Kyoto University. He specializes field-based research on water, sanitation, and hygiene for development. His research topics include septic tank and fecal sludge management, microbial exposure and diarrhea risk assessment, greenhouse gas emission from sanitation services, resources-oriented sanitation, and material flow analysis for low and middle-income countries. He currently serves on the board of directors of Nippon International Cooperation for Community Development (NICCO). He is also on the editorial boards of the journals Sanitation Value Chain (SVC) and African Study Monographs (ASM).
