What does the term ecumene mean in population geography?

• A. The portion of Earth's surface that is inhabited by humans.
• B. The portion of Earth that is uninhabitable.
• C. The total land area of the planet.
• D. The climate zones of Earth.

Answer: (A)

The term ecumene refers to the parts of Earth where humans can live in a relatively permanent way given environmental conditions and available technology. It focuses on inhabited areas, not every square mile of land. The idea is that certain environments are suitable for sustained settlement while others are too harsh or inaccessible, at least with current technology. As people develop irrigation, infrastructure, and medicines, the ecumene can expand into areas that were once uninhabitable; as conditions become harsher or resources scarce, it can contract. Because of this, ecumene describes the inhabited portion of the world, not the entire land area, not uninhabitable regions by themselves, and not climate zones. This makes it the best description of the concept.
