On top of the Schieblock officebuilding in the center of Rotterdam the largest rooftopfarm in Europe is situated: “the DakAkker”. Here fruits, vegetables and herbs are grown and honey bees are kept. The DakAkker functions as a testsite to experiment with different ways of greenroofs and farming in the city. The Dakakker was created in April 2012 by Binder Groenprojecten and initiated by ZUS [Zones Urbaines Sensibles] and developed by ZUS in collaboration with the Rotterdams Milieucentrum (Environmental Centre Rotterdam). The DakAkker is one of the projects of the City Initiative The Luchtsingel and exhibition-site during the International Architecture Biennale 2012.
