Rapport scientifique de fin de projet PSDR new-DEAL « Diversité de l’Elevage en Auvergne : un Levier de durabilité pour la transition agroécologique »

Abstract : -Understanding benefits of herbivore farming system diversity In the last decades, the market context has increased the specialization of livestock farming systems and production areas. However, in the Auvergne region, ruminant production areas still display high levels of diversification as the result of history and contrasted pedoclimatic conditions. Among agroecological principles, it has been assumed that incorporating diversity into livestock farming systems could increase their multiperformance and enhance their resilience. Technical references are however still missing. Research-development project New-DEAL (2015-2020) provided technical and organizational knowledge on/for multi-species grassland-based systems and integrated crop-livestock systems. Research was conducted across spatial scales, from territory to system components (herd, resources and work organization), with a focus on fodder autonomy and system resilience. Various stakeholders were associated to this research: (i) extension agents that provide technical advice to farmers, (ii) teachers of farmer students, and (iii) organizations involved in territorial governance that define local agricultural policies. Two territories underwent extensive analyses: Bocage-Bourbonnais (03) where there is a high occurrence of beef-sheep, beef-saddle horse and beef-crop systems, and Pays de Saint-Flour where multi-species herbivore systems coexist with beef-dairy cattle systems. -A key role of farmer and consumer surveys in our research Individual surveys were conducted with farmers, consumers, and extension and supply-chain agents. These surveys provided quantitative and qualitative information at territory, supply-chain, system and herd levels. At territory scale, we applied the model of territorialized complex goods (or baskets of goods and services) to local consumption. Bundles of services were first analyzed based on previous reports and expert surveys (animal scientists, economists, local stakeholders). More than 120 consumers from these two territories were then directly surveyed for their revealed preferences and willingness to pay for local products. Novelty of our work is that we focused on consumers from rural areas, while most previous studies had investigated preferences of urban consumers. A total of 180 farms surveys were also conducted across the main diversified and specialized herbivore farming systems of Auvergne region. The same number of more focused surveys were sent by post or collected online. We also used a bioeconomic optimization model to provide further economic outputs and explore system resilence to market hazards. Two pluri-annual experiments were conducted at INRAE and IFCE facilities to test for the underlying mechanisms of mixed cattle-sheep and cattle-horse grazing. Finally, six cover crop species were characterized as alternative forages for ruminants. -Key scientific results Several major specificies were highlighted by consumer surveys in both territories: (i) an average basket consisting of a mixture of beef, pork and vegetable, and (ii) a willingness to pay for these products that was more related to territorial vitality, than to the landscape amenities provided by livestock farming. Mixed herbivore and crop-livestock systems were usually larger, for farm and herd size, than specialized systems of the same area. Enlargement of farm area led to a significant increase in equipments and may simplify herd and pasture management. However, a strong reduction of inputs in mixed-grazing and crop-livestock systems was shown to result from a better utilization of grasslands and dilution of parasite burden in mixed grazing systems. Mixed herbivore systems also had enhanced buffer and adaptive capabilities, and so resilience, thanks to opportunities related to housing facilities, animal feeding management and work organization. -Key valorization initiatives A set of 26 synthetic and illustrated support were produced that summarize our main results at different scales. They are ready to be disseminated to non-academic actors in paper and electronic form. Some began to be on social media. Outputs from New-DEAL have already been introduced in initial and adult teachings. The Community of Communes of Bocage Bourbonnais has relied on some of our work to develop its projects. The results of the project are also valued thanks to partnerships committed beyond New-DEAL partners. -Scientific publications A total of eight scientific papers (+ five others that have been submitted) have been published, to which add 16 communications in national or international conferences. These go beyond the classical audience interested in livestock farming systems. A number of technical communications were made in direction to farmers, extension agents, and sometimes a broader audience. Finally, one PhD and 16 Master reports were based on the research carried out in New-DEAL.
