Data or statistical facts on the situation and perspectives of agri-food systems and the impact of policies
46% of agri-food emissions in high-income countries come from out-of-production processes, compared to 35% in middle-income countries and 6% in low-income countries (Sutton, Lotsch & Prasann, 2024).
52 gigatons of GHGs must be reduced to zero by 2050 to limit warming to 1.5°C, but without additional measures, an increase of 3.2°C is projected by 2100 (Sutton, Lotsch & Prasann, 2024).
68% of global agri-food emissions come from middle-income countries, while high-income countries contribute 21% and low-income countries 11% (Sutton, Lotsch & Prasann, 2024).
18-fold increase in annual investments, reaching USD 260 billion, will be required to halve food system emissions by 2030 (Sutton, Lotsch & Prasann, 2024).
15 % emissions could be reduced by reducing fertilizer use or adopting organic agriculture, but this could also reduce agricultural production by 5 %, increase food prices by 13 % and make healthy diets more expensive by 10 % (Sutton, Lotsch & Prasann, 2024).
64% of total employment in low-income countries is in the agrifood sector, compared to 39% in middle-income countries and 11% in high-income countries (Sutton, Lotsch & Prasann, 2024).
USD 20 trillion per year, almost 20% of world GDP, is the cost of negative externalities of the global food system, including impacts not directly perceived by their generators (Sutton, Lotsch & Prasann, 2024).
16 billion metric tons of CO2eq per year, equivalent to 31% of global GHG emissions, come from the global agri-food system, according to more holistic measurements (Sutton, Lotsch & Prasann, 2024).
28% of the world's agricultural land is used to produce food that is wasted (Sutton, Lotsch & Prasann, 2024).
52% of the world's agricultural soils are considered carbon depleted (Sutton, Lotsch & Prasann, 2024).
