Diversifying on-farm incomes insures greater financial independence and value addition opportunities and enable farmers to respond to demand from consumers. In this short video interview with Olivier Lefebvre, economist and co-founder of Perma-projects, let's discover how economic diversification strengthens ecological and socio-economic resilience of farmers and farming systems in Europe. The video interview has been realised within the framework of the first edition of the Month of Agroecology with the financial support from the LIFE Program of the European Union, the Fondation de France and the Fondation Ecotone.
