Whether you're a citizen, an agricultural professional, a development worker, a scientist or a student, we're all concerned by the issues surrounding agriculture and food. The aim of this agroecology dictionary is to inform and raise awareness of the challenges of agroecology to “produce differently” by rethinking production systems, and more broadly, food systems. Each definition has been written by researchers, sometimes in co-construction with students, and is complemented by easily accessible online bibliographical references for more in-depth study of the subject. A genuine educational tool, this dictionary establishes a frame of reference for citizens, farmers, development players, teachers, scientists... It is an essential tool for dialogue between agriculture and society, and can be used by all those wishing to commit to the agro-ecological transition and help practices evolve.
