Incremental, systemic and transformative adaptations have been suggested for reducing the crop vulnerability to these stressful conditions. In addition, innovative cropping systems including low input systems, organic farming, soil and water conservation, intercropping, double cropping, and agroforestry are under strong development in agriculture. Due to its plasticity and low input requirements (nitrogen, water, pesticides), sunflower crop is highly concerned by these new agroecological systems. Apart from current production outputs (yield, oil), ecosystemic services are now expected from the crop and non-food industrial uses are emerging.All these changes should deeply modify crop management and the usual characteristics of genotypes that are grown in the main production areas. After reviewing these changes, we will identify how innovative cropping systems and new environments could modify the traits classically considered up to now, especially in relation to expected ecosystemic services. We will discuss the methods that research could provide for helping to identify adapted traits and design ideotypes.
