The System of Environmental-Economic Accounting for Agriculture, Forestry and Fisheries (SEEA-AFF) is a statistical framework that facilitates description and analysis of agriculture, forestry and fisheries as economic activities and their relationship with the environment. It extends to these primary sectors the environmental-economic structure and principles of the System of Environmental-Economic Accounting Central Framework (SEEA CF), an official UN statistical standard. The SEEA-AFF defines core national accounting tables, easily integrated into synthetic view tables, provided as a basis for the measurement and reporting of information on physical and monetary assets and flows accounts on natural resource use, production, trade and consumption of food and other agricultural products. It thus offers countries a robust statistical structure for the development of agri-environmental indicators, including SDGs, which can be monitored in a transparent, coherent and internationally comparable manner.
