In rural areas, land use and cover change is often the cumulative result of individual farmer decisions. The goal was to construct a spatial typology of farming systems and assess their influence on the extent and spatial distribution of deforestation, forest re-growth, and agriculture expansion in southern Chile between 1999 and 2007. We present a farm typology and its spatial rendering through the combination of farm-cadastral information and land cover and change data. Using multivariate statistical methods, four types were identified.

Soil erosion is a growing problem in Central Chile, particularly in coastal dry lands, where it can significantly decrease the productivity of rainfed agriculture and forestry. In this study, the Revised Universal Soil Loss Equation (RUSLE) was integrated into a Geographic Information System (GIS), and used to evaluate the effects of different combinations of vegetative cover on soil erosion rates for Santo Domingo County in Central Chile. Implementing RUSLE in the GIS required a complete description of the countys soils, climate, topography and current land use/land cover.
