The word "geography" means Earth-description. The subject has its roots in Ancient and was established as a modern academic discipline in the mid-1800s. The subject was then divided into and Earth science, Physical Geography, and a social science, Human Geography. There is now a shared ambition to once again see geography as a whole, in order to understand how humans shape and use the landscape. The need for the integration of human and physical geography is increasing in social planning, environmental issues and other traditional geographic tasks.
