Growing evidence demonstrates that bundling measures manages trade-offs and unforeseen consequences that emerge when implementing these interventions together. However, implementation feasibility and effectiveness depend critically on regional context. Using an ensemble of ten global economic models, we decompose the contributions of four food systems transformation measures: increased agricultural productivity, reduced food loss and waste, dietary shifts toward EAT-Lancet recommendations, and ambitious climate mitigation policies, across thirteen world regions. We find that this style of food system transformation sees the agricultural sector contract and reorient globally, but that the mechanisms driving this contraction differ across regions and cluster into two broad archetypes: a cost-led contraction, where mitigation policies and, to a lesser extent, dietary shifts raise production costs, as in South and Southeast Asia and Sub-Saharan Africa; and a demand-led contraction in livestock-intensive regions such as South America, where dietary shifts depress both production and producer prices. The dominant transformation measure and the severity of associated trade-offs differ systematically across these archetypes, demonstrating that while comprehensive bundling is necessary everywhere, regional priorities must vary. |
