Clemens Stolk carries out program management for the research program Better Plants for New Demands – which includes about 50 public-private research projects in the field of plant breeding. From 2014 to 2016, this was commissioned by TKI Propagation Materials, the executive body of the Topsector policy for the plant propagation material industry. As of 2017, the research program has its own supervisory committee to which Clemens reports. The secretariat of this committee is held by Plantum. The emphasis in this assignment is on increasing the impact of the projects.
