Geography is a well established discipline and it has historically been focused on two main branches: human (urban, political, transportation, health to name a few) and physical(hydrology, climatology, glaciology to name a few). In the early to middle of the 20th century geography had more areas of inquiry emerged, they are: regional and Geographic Information Systems, or GIS.
However in the later portion of 20th century, there was an emergence of a new branch of geographic inquiry. With these intertwining of research from all the branches of geography created a new branch. This new branch is referred as environmental geography, or its other name is integrated geography. To define this new branch of geography: it is to describe the positive/negative feedbacks and other phenomena between humans, human-built environments and natural environments with a defined scale over a spatio-temporal structure.
Environmental geography can include all these topics from the image above. Additionally, it is how human activities over time have effected nature and then how nature has responded back on past and current human activities.
What human activities that is effecting nature:
- Land use and change
- Damming of rivers
- Pollution of air, soil and water
- Greenhouse gas emissions
What has changed with nature from human activity that is now effecting humans:
- Climate change
- Rising sea level
- Eutrophication of rivers, lakes and oceans
- Forest fires
- Stronger storms like hurricanes, tornadoes, typhoons
Literature is thin on this topic based on search results via Google Scholar, as of Jan 1 2014; for “integrated geography” has only 250 articles and “environmental geography” has 3,520 articles; versus “human geography” or “physical geography” which both have over 100,000. By all means using Google Scholar is not the best option; but if you do not have access to academic scholarly databases, it is the closest means of having the most options to get scholarly research papers.
