Interaction between farming systems, riparian zones, and landscape patterns: a case study in western France

We analyze the factors driving land use within and outside riparian zones in four small (about 800 ha) watersheds in Brittany. The results show a difference between riparian and non-riparian zones (less used for grassland), but other factors are also important, such as field size or farm management type. In large farms, small fields are easily abandoned. A multivariate analysis with farm and field characteristics explains 30% of land use variation. Our results suggest that farm type deflects land use from the regional mode, so it is important, in the implementation of environmental zoning, to assess constraints at the farm level.
