Landscape and territory agronomy analyses the two-way relationship between farming practices and land patterns. It takes into account both agroenvironmental and socio-economic processes. A conceptual framework is presented to facilitate understanding of the complex interactions between the disciplines that contribute to this new field of research. We discuss the organisational issues that arise at various spatial and temporal scales during the development of territory-based case studies and research projects. The territory agronomy approach is a participatory action science. Building on our experiences, we propose conceptual research-education-action platform for land management and territorial development. It demonstrates that the Territory Agronomy Approach is an iterative process where researchers, teachers, trainers and stakeholders develop new questions and methods through participation. These characteristics make the territory agronomy approach adapted to promote the territorial dimension in research, education and training activities on farming systems.
