Model and input data related to: Circularity in animal production requires a change in the EAT-Lancet diet in Europe

Summary

Repository contains input data for and model code to run the resource allocation model. The model is a linear optimisation model with an objective function to maximise human edible protein from livestock (dairy, beef, pigs, laying hens, broiler chickens, salmon and tilapia) while satisfying their nutritional requirements from a given availability of feed. The availability of feed is based on the low opportunity cost biomass (co-products, food waste, and grassland resources) produced from the EAT-LANCET diet and grasslands in the European Union 27 + United Kingdom. Two different availabilities of co-products and food waste are provided, one from the original EAT-LANCET diet and a second from a refined grain version of the EAT-LANCET diet. In addition the model can calculate the associated GHG emissions from livestock and steer livestock production to meet the animal-sourced food requirements of the EAT-LANCET diet.
