Integrated geography (also referred to as integrative geography, environmental geography or human–environment geography) is where the branches of human geography and physical geography overlap to describes and explain the spatial aspects of interactions between human individuals or societies and their natural environment, these interactions being called coupled human–environment system. As the discipline of geography is fundamentally interdisciplinary, integrated geography is at the discipline's core and is less of a branch than the trunk from which the other branches diverge. Summed up, environmental geography is about humans and nature and how we affect the environment and our planet.
It requires an understanding of the dynamics of physical geography, as well as the ways in which human societies conceptualize the environment (human geography). Thus, to a certain degree, it may be seen as a successor of Physische Anthropogeographie (English: "physical anthropogeography")—a term coined by University of Vienna geographer Albrecht Penck in 1924—and geographical cultural or human ecology (Harlan H. Barrows 1923). Integrated geography in the United States is principally influenced by the schools of Carl O. Sauer (Berkeley), whose perspective was rather historical, and Gilbert F. White (Chicago), who developed a more applied view. Integrated geography (also, integrative geography, environmental geography or human–environment geography) is the branch of geography that describes and explains the spatial aspects of interactions between human individuals or societies and their natural environment, called coupled human–environment systems.
The links between human and physical geography were once more apparent than they are today. As human experience of the world is increasingly mediated by technology, the relationships between humans and the environment have often become obscured. Thereby, integrated geography represents a critically important set of analytical tools for assessing the impact of human presence on the environment. This is done by measuring the result of human activity on natural landforms and cycles. Methods for which this information is gained include remote sensing, and geographic information systems. Integrated geography helps us to ponder the environment in terms of its relationship to people. With integrated geography we can analyze different social science and humanities perspectives and their use in understanding people environment processes. Hence, it is considered the third branch of geography, the other branches being physical and human geography.
