Along with other methods to describe the status quo in the case studies, the three decision support tools (DST), namely SMART, Cool Farm Tool and COMPAS, were applied to provide information sustainability performance of current agroecological farming systems. Whereas SMART performs a multi-criteria analysis (MCA) and covers a wide range of sustainability themes, COMPAS focuses in depth on economic parameters, and Cool Farm Tool calculates the carbon and water footprint for a given farm enterprise. Cool Farm Tool also offers a biodiversity rating of the whole farm, based on a multi-criteria assessment, similar to SMART. This methodological brief is one of a set produced by the H2020 UNISECO project. Others are accessible on the Zenodo repository under the UNISECO Community. UNISECO is a European research project aiming to develop innovative approaches to enhance the understanding of socio-economic and policy drivers and barriers for further development and implementation of agro-ecological practices in EU farming systems.
