Mountain research or montology, traditionally also known as orology (from Greek oros ὄρος for 'mountain' and logos λόγος), is a field of research that regionally concentrates on the Earth's surface's part covered by mountain landscapes.
Different approaches have been developed to define mountainous areas. While some use an altitudinal difference of 300 m inside an area to define that zone as mountainous, others consider differences from 1000 m or more, depending on the areas' latitude. Additionally, some include steepness to define mountain regions, hence excluding high plateaus (e.g. the Andean Altiplano or the Tibetan Plateau), zones often seen to be mountainous. A more pragmatic but useful definition has been proposed by the Italian Statistics Office ISTAT, which classifies municipalities as mountainous
The United Nations Environmental Programme has produced a map of mountain areas worldwide using a combination of criteria, including regions with
In a broader sense, mountain research is considered any research in mountain regions: for instance disciplinary studies on Himalayan plants, Andean rocks, Alpine cities, or Carpathian people. It is comparable to research that concentrates on the Arctic and Antarctic (polar research) or coasts (coastal research).
In a narrower sense, mountain research focuses on mountain regions, their description and the explanation of the human-environment interaction in (positive) and the sustainable development of (normative) these areas. So-defined mountain research is situated at the nexus of natural sciences, social sciences and humanities. Drawing on Alexander von Humboldt's work in the Andean realm, mountain geography and ecology are considered core areas of study; nevertheless important contributions are coming from anthropology, geology, economics, history or spatial planning. In sum, a narrowly defined mountain research applies an interdisciplinary and integrative regional approach. Slaymaker summarizes:
