Book excerpt: Health issues such as the emergence of infectious diseases, the potential influence of global warming on human health, and the escalating strain of increasing longevity and chronic conditions on healthcare systems are of growing importance in an increasingly peopled and interconnected world. A geographic approach to the study of health offers a critical perspective to these issues, considering how changing relationships between people and their environments influence human health. An Introduction to the Geography of Health provides an accessible introduction to this rapidly growing field, covering theoretical and methodological background. The text is divided into three sections which consider distinct approaches and techniques related to health geographies. Section one introduces ecological approaches, with a focus on how natural and built environments affect human health. For instance, how have irrigation projects influenced the spread of water-borne diseases? How can modern healthcare settings, such as hospitals, affect the spread and evolution of pathogens? Section two discusses social aspects of health and healthcare, considering health as not merely a biological interaction between a pathogen and human host, but as a process that is situated among social factors which ultimately drive who suffers from what, and where disease occurs. Section three then considers spatial techniques and approaches to exploring health, giving special focus to the growing role of cartography and geographic information systems (GIS) in the study of health. This clearly written text contains a range of pedagogical features including a wealth of global case studies, discussion questions and suggestions for further reading at the end of each chapter, a colour plate section and over eighty diagrams and figures. The accompanying website also provides presentations, exercises, further resources, and tables and figures. This book is an essential introductory text for undergraduate students studying Geography, Health and Social Studies.
