Sustainable decision-making in agricultural management requires integrated data to holistically address ecological, social, and economic aspects. This presentation provides an overview of an interactive planning tool for on-farm sustainability assessment developed within the BMEL-funded “DaVaSus” project at Gut&Bösel (Brandenburg). The tool captures, integrates, and analyzes farm, sensor, and environmental data to make ecological, social, and economic effects measurable, usable, and monetarily assessable. Development processes, potentials, and challenges regarding interoperability and data quality, as well as transferability to other farms, are discussed from both research and practical perspectives.
