The City of Rotterdam supported the creation of the DakAkker, one of the largest smart rooftop farm in Europe. A 1000 m2 rooftopfarm on top of the Schieblock in Rotterdam. The project was undertaken by ZUS society in 2012, and created by Binder Groenprojecten, in collaboration with the Rotterdam Environmental Centre. The building is fitted with a smartroof that works as a sensor, predicting extreme rainfall and making extra waterstorage capacity available 24 hours in advance. DakAkker produces vegetables, edible flowers, fruit and bees are kept, allowing biodiversity protection and providing an educational space. It is also an area used to experiment new vertical farming methods in the city.
