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. Topics covered here include but are not limited to geographical approaches to solidarity in economic issues, indigenous knowledge, international relations, global geopolitics, climate change, crisis management, human heath, and more.
