The assessment of agri-food system sustainability requires a multi-criteria approach based on multidisciplinary efforts. Scientists Gésan-Guiziou et al. analyzed the diversity and potentiality of multi-criteria decision analysis techniques in agri-food research. They showed a strong influence of scientific disciplines on the methods used and suggested potential improvements. To become more effective, these methods must extend to ecosystem services and include participatory science actors in the construction and decision processes.
