Climate change is presenting humanity with its biggest challenge ever and calls for an understanding of the interdependencies and connectedness between humanity and nature. The fields of architecture and law are both relevant in this common effort to ensure sustainable development. To facilitate this transformation, Dreyers Fond is housing a series of debates in the Valencia building on Vesterbrogade in Copenhagen under the common heading ‘agenda : EARTH’. The second ‘agenda : EARTH’ event is titled ’Materialer – vedvarende værdi og/eller cirkulation’ (Materials: Lasting value and/or circulation). The event includes performances and an interdisciplinary panel debate by Søren Nielsen, partner at the architecture firm Vandkunsten; Henriette Soja, lawyer and partner at Horten; Rolf Andersson, head of development in the non-profit housing administration organization KAB; and Justine Bell, partner at the architecture firm Djernes & Bell.
