Geography is an integrated study of the earth's places, societies, environments and landscapes. It is unique in bridging the social sciences and humanities (human geography) with earth system science (physical geography). Geography puts this understanding of social and physical processes within the context of places and regions - recognizing the great differences in cultures, political systems, economies, landscapes and environments across the world, and the links between them. In earth systems science we study natural processes, their interactions, and both naturally and human-generated environmental issues. In the social sciences we study a variety of social problems, with a special focus on the uneven distribution of resources and services at scales from the local to the global. In humanities research we explore how human beings have made, and continue to make, the places (physical, social and metaphorical) in which they live.
