“So we looked at what this system would look like in a hypothetical degrowth world: On the basis of a review of degrowth propositions, we created a set of scenarios to feed into a food and land systems computer system simulation to explore their impact on the food system,” David Chen, a scientist at the Potsdam Institute for Climate Impact Research and author of the study, discusses. What we found is that the current food system is generally unsustainable for any society, regardless of economic development rates.”
The simulations reveal that simply slowing growth in rich countries would not yield sizable sustainability benefits in the food system. Importantly, a sustainable food system change that takes into account all expenses for the environment would entail a minor increase in food rates– felt specifically by the bad, the scientists show.
The simulations reveal that just slowing growth in abundant countries would not yield large sustainability advantages in the food system. Financial transfers from higher- to lower-income countries within the existing advancement paradigm may even increase emissions. That is because carbon-intensive diet modifications towards animal items and processed foods are most noticable when countries progress from low to medium incomes.
However, when the scientists consisted of consumption changes and efficiency gains incentivized by a cost on carbon, the outcomes showed an enhanced dietary outcome for all customers, lower greenhouse gas emissions, and, as an outcome, also less economic activity in agriculture required for food production. “For the food sector, we can state that a specific degree of degrowth would be the outcome of the sustainable improvement, not the starting point,” says Hermann Lotze-Campen, co-author from the Potsdam Institute. “So basically this is not really about less however about various growth.”
Notably, a sustainable food system transformation that takes into account all costs for the environment would involve a minor boost in food costs– felt particularly by the bad, the scientists reveal. Any improvement for this reason must be accompanied by a well-thought-out policy mix of wise taxing plans, social payment for CO2 rates, and worldwide transfers.

According to a brand-new research study, we require to change the global food system in order to considerably reduce greenhouse gas emissions.
” Just shrinking the size of our present food system will not cut emissions much. Rather, we require to transform the very nature of that worldwide food system,” says Benjamin Bodirsky, a scientist at Potsdam and the World Vegetable Center in Tainan, Taiwan, and author of a new research study published in the journal Nature Food.
” That means on the one hand that people consume what they require in terms of dietary requirements, curb food waste and consume a more balanced diet plan, with much more veggies and less animal items. On the other hand, a qualitative improvement suggests more effectiveness, thus producing food in a less-polluting way: smarter dosing of fertilizers or planting higher-yield crops. Likewise, carbon prices might help steer farmers towards lower-emission agricultural practices, due to the fact that emitting less then indicates paying less. Put together, this could considerably reduce greenhouse gas emissions.”
