The Chambers of Agriculture and other organizations, which are endorsed by the FNSEA network, support distributor activities, and contribute to the organization and information of collections, either on a county or regional scale. Thanks to this collaboration, the number of participants getting involved in collections is constantly rising. 

The Chambers of Agriculture are public bodies run by elected representatives and represent the whole of the rural and agricultural world. The main activities of the Chambers include: endorsing agricultural companies, agronomy and the environment, local and district development; setting up quality schemes for products and supporting the industry in general.
The FNSEA has been bringing together all regions and all agricultural production in France since 1946 and today, unites approximately 70% of French farmers. 
Based on innovative and sustainable agriculture, the FNSEA unites farmers who carry out the three principal functions of their profession: 
- Production: provide healthy and quality products to the consumer 
- Territorial: manage the open green spaces, work the land and preserve the countryside and natural resources 
- Social: create employment and lead rural communities.
In the territories, the FDSEA (FNSEA’s departmental federations) carry out local actions.
