Graduated as a philosopher of culture I joined the Nature For Health foundation in 2013. Therefore I was a member of the provincial parliament of the Province of North Brabant (leading the GreenLeft Party), and after that an alderman (the first alderman for biodiversity and climate in the Netherlands) and vice mayor in my home town Oisterwijk in the Netherlands, one of the first so called ‘dementia friendly municipalities’ in the Netherlands. Dementia being one of the greatest societal challenges in the Netherlands, and the world. After that I became president of the Dementia Cooperation Oisterwijk, that strives to, because you cannot change people suffering from dementia, change society. And nature can play a part in this. As Nature for Health we have conducted two scientific researches with Dutch Universities on how nature can play a part in this societal challenge. A research on nature interventions, resulting in an Nature4Dem method to improve through nature the quality of life of people suffering from dementia,. And a research ‘Green for Gray’, how you can improve public space for people suffering from dementia. Both researches were nominated for the International Dementia Wards in 2015, category, Dementia Design Innovation of the Year.
