#51 Feedback from 30 years of research on alley cropping systems with Christian Dupraz

What have we learnt from 30 years at one of the most prominent agroforestry research sites in the world? In collaboration with AGROMIX, We are excited to present an interview with Christian Dupraz, a leading agroforestry researcher from INRAE Montpellier. This is one of our rare 'in person' interviews where we discussed years of findings under the alley cropping walnut trees of the Domaine de Restinclières. We analysed many technical details such as tree - crop competition, tree pruning and adapted tree species. We also discussed socio-economic aspects such as the relationship with the local farmers and the reason why alley cropping systems have not yet been scaled. Enjoy!
