Feeding efficiency gains can increase the greenhouse gas mitigation potential of the Tanzanian dairy sector.

ABSTRACT: We use an attributional life cycle assessment (LCA) and simulation modelling to assess the effect of improved feeding practices and increased yields of feed crops on milk productivity and GHG emissions from the dairy sector of Tanzania's southern highlands region. We calculated direct non-CO₂ emissions from dairy production and the CO₂ emissions resulting from the demand for croplands and grasslands using a land footprint indicator. Baseline GHG emissions intensities ranged between 19.8 and 27.8 and 5.8-5.9 kg CO₂eq kg^-1 fat and protein corrected milk for the Traditional (local cattle) and Modern (improved cattle) sectors. Land use change contributed 45.8-65.8% of the total carbon footprint of dairy. Better feeding increased milk yields by up to
