De decentralisaties van de zorg aan langdurig zieken en ouderen, jeugdzorg, en werk en inkomen die vanaf 2015 zijn doorgevoerd in Nederland hebben geleid tot een transitie van een centraal naar een lokaal stelsel van zorg en welzijn. Deze transitie beoogt zorg en ondersteuning dichter bij de inwoners…

Flying is cheaper than driving a car, but a disaster for the environment. Yet few politicians dare to levy excise duty on kerosene. This is only one example from a world where emotions and yelling are burying facts, and in which scientists lose connection with society.

Life returned to something resembling normal after Covid but other crises soon took its place. These great challenges are also being felt at the University and our researchers are working on solutions. The nitrogen crisis, problems with young people’s services and an increasingly urgent climate crisis:…
