Co-designing agroecological systems combining poultry and plants to enhance (eco)system services and identify genetic needs for poultry

The agroecological transition requires a better coupling of animal and plant productions to take advantage of reciprocal benefits. However, poultry farming is often disconnected from crop production at both farm and regional levels. Additionally, current breeds and varieties may struggle to adapt to the variable and heterogeneous environments often found in agroecological systems. Furthermore, the agroecological transition requires a shift in research practices, including the active engagement of non-scientific stakeholders to ensure effective field implementation. In this context, this study aimed to co-design agroecological systems integrating poultry with crops or fruit trees to enhance ecosystem services. The goal was to refine breeding objectives and optimize poultry sector organization in terms of feeding, genetics, and economics. To achieve this, we conducted semi-structured interviews with farmers across France who are experimenting with innovative practices in more integrated systems. Initial findings show that poultry-crop systems offer multiple benefits, including diversification, food autonomy, and biological pest control. However, they also present challenges, particularly due to unsuitable regulations and equipment. While farmers' satisfaction with current poultry genetics varies, all farmers seek greater independence from dominant industry players. Achieving this goal necessitates collaboration between, breeders, farmers and local stakeholders at the regional level. Building on this observation, we applied the DKCP (Define-Knowledge-Concept-Proposal) method to facilitate knowledge sharing and explore innovative ideas during a codesign process. This phase involved a group of organic farmers in the Massif Central, a mid-altitude region in central France.
