calcMulticroppingYieldIncrease

Calculates yield increase achieved through multiple cropping (as factor of off season to main season crop yield) under irrigated and rainfed conditions respectively. Optionally: return which grid cells are potentially suitable for multiple cropping activities under rainfed and irrigated conditions. Calculation is based on grassland gross primary production (GPP) in the growing period of the respective crop and annual grass GPP.
