"This project aims at providing a framework for assessing sustainability levels in Belgian agricultural systems (SAFE) that overcomes the deficiencies mentioned above [...] In this project, in parallel to the theoretical construction of the tool, four farms with different production systems and agricultural practices were chosen as test sites. These farms served as a support for the development and the testing of the SAFE tool and methodology: each was monitored during two years and the collected data was used as input for case-studies. Whereas indicator results in these test sites are presented and commented in this report, they cannot be used for comparing different management types: these four farms are most definitely not a representative sample of Belgian agriculture, in part because some used innovative agricultural practices.
