Do pasture-based mixed dairy systems with higher milk production have lower environmental impacts? A Uruguayan case study

The increased milk production of pastured-based mixed dairy systems has involved higher use of concentrates and inputs, which led to increased environmental impacts. Usually these impacts are expressed per unit of product, which does not reflect the local impact per unit of land. The objective of this paper was to estimate global and local environmental impacts per kg of milk and per hectare. Fossil energy use, greenhouse gas emissions, water...
