Fig. 6: Livestock AMUQ trajectories by 2040 under different scenarios.

This figure shows the projected antimicrobial usage quantity (AMUQ, in tonnes) in livestock from 2019 to 2040 under eight scenarios outlined in Table 1, reflecting varying assumptions regarding livestock biomass (LBIO) and antimicrobial use intensity (AMUI). The bold lines represent the BAU (Business-as-Usual) scenario, as well as Scenario (S4), which assumes a 30% reduction in AMUI while keeping LBIO at the BAU level, and Scenario (S7), which assumes a 50% reduction in AMUI while maintaining LBIO at the BAU level. These scenarios illustrate the impact of AMUI reduction on AMUQ, independent of changes in livestock biomass.
