Soil fertility in the mid-elevation hillsides of the Cochabamba region of Bolivia has been declining as natural fallow times have been reduced in order to bring more land into crop production. A photothermal model is used to simulate climate

and slopes of 20 to 30 % is also tested. After EUROSEM is parameterized for local conditions, it is used to simulate the likely impact of live barriers of Phalaris grass on catchment-wide soil erosion rates. - (SLD)

A. discuss a methodology, based on EUROSEM, SLOPE/w and SEEP/w models, for quantifying the effects of live barriers on the stability of agricultural land in the Andean valleys of Bolivia. The methodology involves computer simulation of slope
