For the research program Better Plants for New Demands – the ‘umbrella’ for about 50 public-private research projects in the area of plant breeding – Clemens is responsible for the program management. From 2014 until 2016 this was commissioned by Foundation TKI Propagation Materials, the executive agency of the Dutch ‘top sector’ policy for the plant propagation industry. As of 2017, the research program has its own guidance committee to which Clemens reports. The secretariat of this committee is being provided by Plantum. The emphasis in this assignment is at increasing the impact of the research projects.
