Changes in cropland have been the dominating land use changes in Central and Eastern Europe, with cropland abandonment frequently
exceeding cropland expansion. However, surprisingly little is known about the rates, spatial patterns, and determinants of
cropland change in Eastern Europe. We study cropland changes between 1995 and 2005 in Argeş County in Southern Romania with
two distinct modeling techniques. We apply and compare spatially explicit logistic regressions with artificial neural networks
(ANN) using an integrated socioeconomic and environmental dataset. The logistic regressions allow identifying the determinants
of cropland changes, but cannot deal with non-linear and complex functional relationships nor with collinearity between variables.
ANNs relax some of these rigorous assumptions inherent in conventional statistical modeling, but likewise have drawbacks such
as the unknown contribution of the parameters to the outcome of interest. We compare the outcomes of both modeling techniques
quantitatively using several goodness-of-fit statistics. The resulting spatial predictions serve to delineate hotspots of
change that indicate areas that are under more eminent threat of future abandonment. The two modeling techniques address two
controversial issues of concern for land-change scientists: (1) to identify the spatial determinants that conditioned the
observed changes and (2) to deal with complex functional relationships between influencing variables and land use processes.
The spatially explicit insights into patterns of cropland change and in particular into hotspots of change derived from multiple
methods provide useful information for decision-makers.
