Our food system today is controlled by a handful of companies, that influence a lot regulations through lobbying in order to protect their financial interests. The power has shifted over the past decades from the producers to the food corporations, who control the whole food chain, from seeds to retail, leaving the farmers under pressure, and resulting in countless negative externalities: greenhouse gases, nutrients decrease, soil and water pollution, health consequences, dead marine zones, antibiotics resistance, farmers suicides. Patents on life filed by those corporations are not only a threat for global food sovereignty, but also, an important cause of destruction of the biodiversity of our planet. How can decentralized, open source and collaborative initiatives in farming practices, equipments and distribution transform our food system for the better? That's the question we are going to debate in this session.
