Geography occupies a distinct place in the world of learning, offering an integrated study of the complex reciprocal study relationships between human societies and the physical world. The geographer’s canvas is collared by place, space and time: differences and dynamics in cultures, political systems, economics, landscapes and environment across the world, and the links between them. The discipline has traditionally focused on Human and physical Geography. In recent years, however, a third category has been recognized: Environmental Geography. This deals with the multifaceted nexus between human society and the environment. Geographic information system (GIS) and Remote Sensing are the two additional areas where geographers are playing the most prominent role.
