The goal of the ‘Thinking Global’ component is mainly to design transition social business models that can be financed and will be part of a doctoral thesis. As the GAECs and other agricultural organizations are unable to make ends meet, the model must be reinvented and, above all, sustainable financing independent of the CAP, that functionalize farmers, must be allowed. The abandonment of chemical inputs, the use of farmers’ seeds (reusable), the low use of water and oil offer economically viable fertile paths. This is what the project at the global level based on concrete local experimentation must demonstrate. Reflection on these issues in the ‘Act Local’ component will be fuelled by concrete and significant agroecological experimentation. The objective is to set up and evaluate various agroecosystems to ensure agricultural production (quantity and quality) adapted to the environmental conditions of the Courmettes site (06 – Tourrettes-sur-Loup).
Thus, under the soil and climate conditions described below, a detailed study of the functional diversity of organisms and microorganisms and their management will be carried out within these ecosystems in order to limit the effects of water stress, especially in the summer period, for example. The goal is also to establish a method for selecting varieties and species grown in association by comparing them with those used in monoculture in order to determine the most suitable for the soil’s pedoclimatic and biological conditions. In addition, the best associations between vegetable plants and fruit trees will be analysed. The experiment will focus on the use of heirloom varieties recommended by Natura 2000 agents or varieties selected by seed companies under conditions similar to those of the Courmettes site. As the soil is very draining, it will be necessary to limit erosion and streaming phenomena, to study potential positive interactions with cultivated plants, particularly via fungal networks of mycorrhizal types using agroforestry methods, and finally to ensure humidity, especially during rainfall deficient episodes.
