Abstract: 
To meet policy goals targeting increasing the share of organic agriculture, an organic seed needs to be provided. Currently, this is far from being the case. This study investigates two cases of important crop country combinations in organic agriculture, namely perennial ryegrass in South-West England and durum wheat in Italy. A novel multi-agent value chain approach was developed to assess public and private-sector interventions aiming at increasing organic seed use. Phasing out of derogations for non-organic seed comes with 2-7% gross margin losses at the farm level. Seed producers and breeders profit by 9-24%. Mitigating measures can be subsidies of 28 euro/ha or price premiums of 12 euro/ton at the farm gate for durum wheat, in the case of durum wheat in Italy, and subsidies of 13 euro/ha or price premiums of 70 euro/ton for lamb meat, in the case of perennial ryegrass in England. Further mitigating measures are the promotion of farm-saved durum wheat seed and investments in breeding for better nitrogen efficiency in organic perennial ryegrass seed production.
