Land use related to food production is generally quantified using product-based life cycle assessments. We, however, quantified land use of diet scenarios with a land use optimization model. Energy and protein requirement of human populations, varying from 15 to 30 mil-lion people, were met with the consumption of arable crops, meat and milk. Diet scenarios explored contained 0% up to 80% of animal protein. First findings show that a limited contribution of animal protein in the diet resulted in lowest land use per capita, because of utili-zation by livestock of products inedible for humans. Moreover, utilization of land unsuitable for crop production provides the opportunity to sustain a larger population compared to a situation in which these soils were not used to produce food.
