For the biophysical yield effects due to climate and area changes, yields as calculated by IMAGE’s crop model are communicated to MAGNET. External assumptions on autonomous technological changes are mostly based on FAO projections ([[Bruinsma, 2003]]). They describe. per region and commodity, the assumed future changes in yields for a wide range of crop types. In MAGNET, the biophysical yield changes are combined with the autonomous technological change, to give the total exogenous yield change. In addition, during the simulation period, MAGNET calculates an endogenous intensification as a result of price-driven substitution between labour, land and capital. In IMAGE, regional yield changes due to both autonomous technological change and endogenous intensification according to MAGNET are used in the spatially explicit allocation of land use [[Agricultural systems]]. | For the biophysical yield effects due to climate and area changes, yields as calculated by IMAGE’s crop model are communicated to MAGNET.
