Abstract
Understanding the socioeconomic implications of food systems transformation requires exploring regional differences. Using a multi-model ensemble of nine global economic models, this paper investigates the socioeconomic implications of two different futures, a business-as-usual and the envisioned future food system. The transformation scenario is composed of dietary change, productivity growth, and halving food loss and waste. The advantage of the multi-model ensemble is to capture uncertainties of different food systems futures. We find that food is becoming more affordable in all regions, but with heterogeneity across food groups. The median price of agricultural products falls by 16% under the transformed food system compared to current trends, mostly driven by a 28% decline in prices of livestock products. The ensemble suggests uncertainties regarding the direction of change in prices of vegetables, fruits, and nuts across all regions. Ensuring a healthy diet for all brings about significant changes in food production and shifts the regional dynamics of trade, with a particular regional dominance in trading specific food groups. In such world, the agricultural sector reshapes and restructures, exposing land-abundant regions to potential socioeconomic implications, and environmental burdens of food systems transformation. A demand-side transformation is feasible but entails political effort to ease the transition of the most vulnerable regions and targeting their vulnerable sectors. This analysis offers science-based insights to guide policymaking in food systems, especially to ensure a transition based on equity principles and actions whereby sustainable development can be achieved.
