abstract = "Land-use change (LUC) is a complex process that is difficult to
project. Model collaboration, an aggregate term for model
harmonization, comparison and/or coupling, intends to combine the
strengths of different models to improve LUC projections. Several
model collaborations have been performed, but to the authors'
knowledge, the effect of coupling has not been evaluated
quantitatively. Therefore, for a case study of Brazil, we
harmonized and coupled the partial equilibrium model
GLOBIOM-Brazil and the demand-driven spatially explicit model
PLUC, and then compared the coupled-model projections with those
by GLOBIOM-Brazil individually. The largest differences between
projections occurred in Mato Grosso and Para, frontiers of
agricultural expansion. In addition, we validated both projections
for Mato Grosso using land-use maps from remote sensing images.
The coupled model clearly outperformed GLOBIOM-Brazil. Reductions
in the root mean squared error (RMSE) for LUC dynamics ranged from
31% to 80% and for total land use, from 10% to 57%. Only for
pasture, the coupled model performed worse in total land use (RMSE
9% higher). Reasons for a better performance of the coupled model
were considered to be, inter alia, the initial map, more spatially
explicit information about drivers, and the path-dependence effect
in the allocation through the cellular-automata approach of
PLUC.",
