Can nudging improve the environmental impact of food supply chain? A systematic review

摘要

Background: According to the prediction of the Food and Agriculture Organization, food supply must increase by almost 70 percent by 2050, with tremendous consequences in terms of land depletion, natural resource use, and greenhouse gas emissions. The current agri-food system is incapable to cope with this raising demand meanwhile preserving the environment. There is urgent need to reorient the food system onto a more sustainable trajectory: producers should pursue more conscious and environmentally friendly practices and consumers should account for sustainability issues while making their daily food consumption decisions.
