The current food production system fails to meet the needs of the current population, while causing major impacts to the environment. Taking an integrated view of these problems shows the way towards policies to change the system, according to a new comment published in the journal Nature by researchers at IIASA and the UN Sustainable Development Solutions Network (SDSN). The article draws on findings from the SDSN’s Deep Decarbonization Pathways Project, and in-depth country policy support projects for food and land-use carried out by IIASA.
