The content of this Mansholt lecture came about through a wide science-policy consultation process. Existing ‘seeds of innovation’ in the biodiversity climate-food nexus were collected in a WUR-wide dialogue on 10th May 2022, which involved some 150 interdisciplinary experts. These seeds were collated into interventions for nature-positive futures, in an interdisciplinary workshop of WUR colleagues on 13th May 2022. They were further clustered into five entry points for nature-positive changes to the food system. The resulting entry points and interventions were discussed with several EU policy makers in another workshop in Brussels on 30th June 2022. We thank everyone involved in this process for their input

Crop protection in prevailing agricultural systems in the EU is highly dependent on plant protection products (PPPs) to protect plants against harmful weeds, pests and diseases. The use of PPPs is a cause of health, environmental and public concerns, and a key question is whether their use can be reduced while maintaining adequate yields. This study provides an overview and description of current and new crop protection practices, including mechanical techniques, plant breeding, biocontrol, induced resistance, applying ecological principles, precision agriculture (PA), and emerging plant protection products. The potential and impact of the new crop protection practices is assessed. It may be feasible to design resilient systems that are economically viable, have limited environmental impact and help improve biodiversity. Diverse cropping systems would have a natural resilience to weeds, pests, and diseases, and potentially reduce the dependency on PPPs, enabled by PA technologies. The main challenge is to integrate new varieties, mechanisation, and biocontrol tools in these systems. Continuous development of all crop protection practices is needed to ensure sufficient control of pests, weeds and diseases. The drivers and enablers for implementing alternative crop protection practices are identified, and an analysis of key legislation to support their use is presented.

Arnhem-Nijmegen is een verstedelijkte regio, in het gebied waar de twee grote rivieren Rijn en Maas elkaar ontmoeten. Dat is een spannende combinatie. Want terwijl de steden groeien, krijgen de rivieren komende jaren steeds meer water te verwerken en vallen ze soms bijna droog. Niet alles kan meer overal; we moeten keuzes gaan maken. Welke ontwikkelingen krijgen prioriteit? Aan de hand van 10 perspectieven schetsen we de Groene Metropoolregio van de toekomst.
