This contributed volume explains the concept of solidarity and illustrates how perspectives informed by a solidarity approach can be utilized in geographic research. Geography offers a set of concepts and tools including space, place, scale, landscape, and mobility, that makes it a particularly useful lens through which to view issues of solidarity. It is distinct from other sciences in its subject matter and methodology but at the same time offers a multidisciplinary approach and transcends its disciplinary boundary. The concept of solidarity in geography is illustrated here through nearly thirty-five case chapters, all from the Indian subcontinent.
