New publication alert 📢 New study on energy inputs for global agrifood systems co-authored by our colleague Martin Bruckner. Key Findings: 💡 Global AFS's energy return on energy investment (EROEI) has improved from 0.68 (1995) to 0.91 (2019), yet remains below 1, highlighting energy inefficiency. 💡 In low-income regions, AFSs are still energy sources, but their EROEI has declined with increasing wealth and growing use of fossil fuels. AFSs of high-income regions are energy sinks, although their EROEI has improved. 💡 Globally, food processing accounts for 40% of total energy use in AFSs, notably larger than fertilizer, which accounts for 17%. 💡 Livestock products consume 60% of energy inputs while delivering less than 20% of food calories. 💡 Reducing the energy demand of AFSs is essential to promote food security, ensure social and economic sustainability for agricultural producers, and reduce environmental impacts. 📖 Read the full study here: https://lnkd.in/dAvrSuuy ...and check out this article ⬇️

Great work by Kajwan Rasul and colleagues in PNAS Nexus. High energy inputs required by modern agriculture have grown slower than food production since 1995. Overall, the agri-food system is a net energy sink rather than the only source as it used to be. Here my reflections on this study important for sustainable development theory. #foodsystem #agriculture #meat #vegetarian #vegan Industrial Ecology NTNU Norwegian University of Science and Technology (NTNU)
