Скачать или смотреть Degrowth scenarios for the food system to reduce greenhouse gas emissions: David Meng-Chuen Chen.

The 3rd Utrecht Degrowth Symposium took place at Utrecht University on 29th September 2023, bringing together policymakers and civil servants, researchers, students, farmers, social movements, and other interested people to explore what a degrowth perspective can bring to the debate on agri-food system sustainability.
In his keynote, David Meng-Chuen Chen (Humboldt University Berlin & Potsdam Institute for Climate Impact Research) discusses a quantitative simulation model (MAgPIE) that integrates degrowth principles in the food and land system. The model was used to explore possible food system scenarios in the light of global greenhouse gas (GHG) emission reduction targets and the nutrition transition. Results show that a structural, qualitative food system transformation can achieve a steady-state food system economy that is net GHG-neutral by 2100 while improving nutritional outcomes.
Chen argued that degrowth in relation to agri-food systems should not be equated with a reduction of GDP or economic activity in the agri-food sector, but rather with a qualitative change of the food system. The food system thus needs to be transformed both in terms of its material scale and its qualitative structure: resource-intensive and highly polluting industries, such as the livestock industry, would need to be downscaled along with a reduced consumption of animal protein. Other subsectors such as horticulture should in contrast be expanded due to their role in preventing malnutrition and chronic diseases. Furthermore, farmers would need to adopt low-polluting management practices, and supply chains would need to shift towards low-polluting source materials. The model suggests that to achieve such transformation, a combined intervention on efficiency (a global GHG tax) and sufficiency (reducing consumption of animal protein) would be needed.
The model also raises many questions about the governance of the food system and indirect consequences of the modelled policies, such as those on agricultural labour, which need to be further investigated by the scientific community.
