B 2.3 Problems of scale in landscdape analysis

[TERCUD]

"As a result, the analysis of landscapes raises problems of scale: many flows take place between the elementary areas of a given landscdape; others cross the boundary between the landscape seen from here, and the landscapes which surround it. This is as true of the ecological as of the social realm. It means that a part of what happens in a given area is linked to, and often caused by, what exists elsewhere: ecosystems are parts of geosystems; social local systems (parishes) are parts of larger ones (counties, regions, states); in the field of economics, prices depend on market places which are often located far away; for culture, the more significant units are often large, which is true of the linguistic or religious ones, for instance.
Problems of scale are significant for many ecological flows: on a slope, within a water catchment, on the leeside of sources of pollution, etc."
