SC 2.8 Adapting cropping systems to a CO2 rich atmosphere: opportunities and challenges for food and water security

 Wednesday 11 May, 08.45 – 10.30, New Orleans Room

Rising atmospheric CO2 concentrations could benefit crops by stimulating biomass production rates whilst improving overall crop water use efficiency. Yet the actual role of CO2 on crop yield and food security remains controversial and assessments of long-term agricultural adaptation tend to overlook crop-CO2 interaction. This session aims to discuss challenges and opportunities in adapting cropping systems to a CO2 rich
atmosphere and to identify a list of priorities in future experimental and crop modelling research that are carefully targeted to stakeholders’ needs. After three presentations from the Impact-Adaptation-Vulnerability modelling and field experiment communities, practitioners and scientists will be invited to debate in a café style setting.
