Shifting our diets to be more sustainable can be a powerful way for each of us to address both climate change and global food insecurity, however making such adjustments at the large scales necessary to make a difference globally can be a delicate matter.
"Changes in food demand in one part of the world can have cascading environmental and human welfare implications for people around the world)," said Joe DeCesaro, data analyst at UC Santa Barbara's National Center for Ecological Analysis & Synthesis .
Using available data on a variety of factors, including countries' average diets, trade flow and the global environmental pressures of food production, the researchers were able to map to a high degree of precision the changes in environmental pressure that would occur with a global shift to each of four types of diets, the mostly vegetarian Indian diet, the plant-forward Mediterranean and EAT-Lancet diets, and average government-recommended dietary guidelines.
Meanwhile, global reductions in pressure, according to the study, would come mostly from dietary shifts in higher-income countries. "Sharing sustainable agricultural practices will help reduce any increases in pressures seen from diet shifts," DeCesaro said. Continuing in this vein, the researchers are currently working to directly analyze current food trade patterns and the subsequent environmental pressures traded with it, with no diet shifts.
