Climate Change and Food Systems
United Nations Food Systems Summit 2021 Scientific Group https://sc-fss2021.org/ Food Systems Summit Brief Prepared by Research Partners of the Scientific Group for the Food Systems Summit, May 2021 Climate Change and Food Systems by Alisher Mirzabaev, Lennart Olsson, Rachel Bezner Kerr, Prajal Pradhan, Marta Guadalupe Rivera Ferre, Hermann Lotze-Campen 1 Abstract Introduction Climate change affects the Climate change affects the functioning of all the components of food functioning of all the components of food systems, often in ways that exacerbate systems1 which embrace the entire range existing predicaments and inequalities of actors and their interlinked value-adding between regions of the world and groups in activities involved in the production, society. At the same time, food systems are aggregation, processing, distribution, a major cause for climate change, consumption, and recycling of food accounting for a third of all greenhouse gas products that originate from agriculture emissions. Therefore, food systems can (including livestock), forestry, fisheries, and and should play a much bigger role in food industries, and the broader economic, climate policies. This policy brief highlights societal, and natural environments in nine actions points for climate change which they are embedded2. At the same adaptation and mitigation in the food time, food systems are a major cause of systems. The policy brief shows that climate change, contributing about a third numerous practices, technologies, (21–37%) of the total Greenhouse Gas knowledge and social capital already exist (GHG) emissions through agriculture and for climate action in the food systems, with land use, storage, transport, packaging, multiple synergies with other important processing, retail, and consumption3 goals such as the conservation of (Figure 1).
