註釋Healthier, more sustainable and more equitable food systems have a key role to deliver progress on all 17 Sustainable Development Goals (SDGs). This study aims at assessing the impact of behavioural changes with regard to food consumption with a focus on the objectives of SDG target 12.3. As a stylised representation of our finite planetary resources, the study employs a recursive dynamic global computable general equilibrium simulation model known as MAGNET, which is ideally suited to examining forward-looking medium- to long-term scenarios. The MAGNET model is macroeconomic in scope with fully internalised gross bilateral trade flows between regions and a full accounting system of global virtual flows for assessing footprints. Moreover, the model has a broad array of economic, social and environmental indicators to fully explore the sustainability implications arising from demand driven changes in the state and potential future evolution of the global food system within the wider bioeconomy. The first scenario investigate the impact of global food waste and loss (FWL) reductions at different points along the supply chain, implemented by 2030 and maintained until 2050. The remaining scenarios build upon the FWL scenario through four sets of experiments: (i) a dual decomposition of the FWL scenario to examine waste and loss reductions in isolation, (ii), variations in associated food supply chain compliance costs to meet the assumed FWL reduction, (iii), an exploration of the resilience of food demand systems to rising fossil energy prices, and (iv) a transformation toward healthier plant-based diets over the period 2020 to 2050 inspired by the EAT-Lancet report. To facilitate the comparison of the diet scenario and FWL scenarios, the share of red meat, white meat and dairy consumption is kept constant in the baseline and all FWL scenarios.
