This article analyzes geo-referenced data to elucidate the relations between deforestation and access to roads andmarkets, attributes of the physical environment, land tenure, andzoningpolicies in Santa Cruz, Bolivia. It presents separate models for Santa Cruz as a whole and for seven different zones within Santa Cruz, as well as for two different time periods (pre-1989 and 1989 to 1994). The relation between deforestation and the explanatory variables varies depending on geographic scale and the zone and time period analyzed. At the department scale, locations closer to roads and the city and places that have more fertile soils and wetter climates have a greater probability of being deforested. The same applies to colonization areas. Protected areas andforest concessionsare less likely to be deforested. Nevertheless, in manyspecific zones, these variables had no significant impact or actually had the opposite impact than in the entire department.Most of these relationswere weaker between 1989and 1994 than in the previous period.
