The mental health of the French agricultural population represents a major public health concern, characterized by an increased vulnerability to suicide due to demanding working conditions, social isolation, economic pressures, and limited access to healthcare in rural areas. In this context, the deployment of the Farm Sentinel Model emerges as a relevant approach to suicide prevention, grounded in a community-based and collaborative framework. Led by the Mutualité Sociale Agricole (MSA), in collaboration with the Groupement d’Études et de Prévention du Suicide (GEPS), the Farm Sentinel Model aims to promote early identification and referral of individuals at risk of suicide through a network of sentinels drawn from, or closely connected to, the agricultural community. Embedded within a national program for prevention and support of agricultural beneficiaries in situations of distress, the model builds on the MSA’s strong territorial presence, its elected representatives, local MSA professionals, and its mutualist values. Sentinel training, developed by the GEPS and tailored to agricultural realities, constitutes a core component of the Farm Sentinel Model. A recent innovation involves the development of agricultural facilitators—non-clinical co-facilitators trained to enhance program ownership within rural communities through a peer-to-peer approach. As of December 31, 2024, more than 8,000 sentinels were active across rural areas in France. Despite persistent challenges, this collaborative and community-based model appears promising for reducing social and territorial inequalities in mental health and strengthening suicide prevention in agricultural settings.
