This book demonstrates a methodology for assessing public health needs in communities experiencing environmental sanitation inadequacies. Centring on a case study of the Republic of Cameroon, the findings represent the starting point of a campaign to implement a comprehensive water and sanitation infrastructure through advocacy, housing improvements, and new service chains. Based on an assessment report undertaken by ARCHIVE Global, an international non-profit organization focusing on the link between health and housing, this book: Explores and establishes a causal relationship between the built environment and its impacts on public health Uses the United Nations' Sustainable Development Goals as a benchmark for highlighting issues and challenges with sanitation infrastructure projects Provides lessons for communities around the world facing environmental health issues similar to those Cameroon's Idenau Municipality deals with. This book is intended for environmental health professionals, academics and policymakers, be they domestic to the African region or multinational practitioners. Donor countries, the likes of the United States and European nations, will also value the book's advocacy for interventions in the built environment and current public health impacts.
