Mountain research

Mountain research or ''montology'', traditionally also known as ''orology''〔http://www.merriam-webster.com/dictionary/orology Merriam Webster〕 (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.
==Mountain areas==
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,〔http://dx.doi.org/10.1553/eco.mont-5-1s3 Editorial. eco.mont 5 (1)〕 others consider differences from 1000 m or more,〔http://www.unep.org/maweb/documents/document.293.aspx.pdf Mountain Systems. UNEP〕 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
* if at least 80% of their territory is situated above 600 m asl, and/or
* if they have an altitudinal difference of 600 m (or more) within their administrative boundaries.〔http://www.istat.it/it/archivio/147760 Precisazione sulla classificazione dei comuni montani〕
The United Nations Environmental Programme has produced a map〔http://old.unep-wcmc.org/medialibrary/2011/09/20/cd73545c/mountain_2000_poster_large.jpg UNEP-WCNC (2011): Mountains of the World – 2000. Map〕〔http://old.unep-wcmc.org/mountains-and-forests-in-mountains-2000_723.html UNEP-WCNC (2011): Mountains of the World – 2000. Data〕 of mountain areas worldwide using a combination of criteria, including regions with
* elevations from 300 to 1000 m and local elevation range > 300 m;
* elevations from 1000 to 1500 m and slope 5° or local elevation range > 300 m;
* elevations from 1500 to 2500 m and slope ≥ 2°;
* elevations of 2500 m or more.
