Model R code and input data used in Pinsard et al. (2022a) "Robust strategies for future meat production and climate change mitigation under imported input constraints in Alentejo, Portugal". The model is a macro dynamic nitrogen balance model of a farming system (MacDyN-FS), adapted from Pinsard et al. (2021) with a greenhouse gas (GHG) balance sub model and a herd dynamics for cattle. The model was used to explore the trade-off between meat production robustness to input import constraints (in a context of global peak oil supply) and net GHG emissions of the beef cattle farming system in Alentejo, Portugal by 2050.
