Assessing environmental and climate impacts of a dietary change with the global partial equilibrium bio-economic model, GLOBIOM

May 18, 2023 @ 12:00 pm - 1:00 pm

BC3 Seminars

Marta Kozicka

Research Scholar at the IIASA Integrated Biosphere Futures (IBF) Research Group of the Biodiversity and Natural Resources Program (BNR)


GLobal BIOsphere Management model (GLOBIOM, Havlík et al. 2014), developed at IIASA is a global economic land use model covering the sectors of agriculture, forestry and bioenergy. GLOBIOM can be used to explore various trade-offs and synergies around land use, ecosystem services and socio-economic objectives. Some of the examples include assessment of linkages between food security and climate change impacts or climate mitigation measures compatible with the Paris Agreement (Frank et al. 2017; Fujimori et al. 2022; Hasegawa et al. 2018, Hasegawa et al. 2019). One of our recent studies (Kozicka et al., in review) investigates climate and biodiversity impacts of a global dietary shift with novel plant-based meat and milk alternatives. We link a global partial substitution of the main animal source foods (ASF) with their novel alternatives based on sets of alternative hypothetical plant-based ‘recipes’, designed to be nutritionally equivalent to the original products and relying on nutritionally and functionally realistic ingredients for global production. We find a substantial reduction in the environmental impacts by 2050 even if 50% of the main animal products is substituted – net reduction of forests and natural land is almost fully halted and agriculture and land use GHG emissions decline by 31% from 2020. If spared agricultural land is restored, climate benefits could double and trends in biodiversity reverse.

In the SWITCH HORIZON project “Switching diets for a just, healthy and sustainable dietary transition through knowledge and innovation”, in collaboration with i.a. BC3, we will develop and assess EU scenarios of food dietary patterns and environmental and socio-economic shifts.
