This collection of essays offers an interpretation of human geography and its significance as a diverse body of intellectual enquiry for imagining, thinking about, living in and changing the world. The book examines the ways in which human geography as a discipline – the intellectual concerns of a specialised yet richly varied field of knowledge – shapes the lived and experienced geographies of the human world and so is vital to its wider analysis, understanding and transformation. The book may, therefore, be described as a dynamic grammar, rather than a strict syntax or vocabulary, of human geography. And this grammar extends well beyond human geography. Our concern is to disclose human geography as a vibrant enterprise of vital significance in informing, framing and shaping social and environmental practices and understandings.
