Transitioning to healthier, more sustainable global food systems by 2050 would substantially reshape agriculture by reducing livestock numbers and decreasing land use, according to a new study published in Nature. Led by Cornell University, with contributions from the Potsdam Institute for Climate Impact Research (PIK) and the Agricultural Model Intercomparison and Improvement Project (AgMIP), the research highlights both the possibilities and challenges of a global food system transformation. It also underscores the urgent need for proactive agriculture and food policies to drive this transformation and manage its socioeconomic impacts.
