For centuries, specialists in art conservation and nature conservation have been developing strategies to conserve, preserve, and protect cultural and natural heritage. Until now, these fields seem to have developed independently of each other – save some exchange of metaphors perhaps. Starting from a broad realization that the aims of fixating in time or restoring into a former pure state are essentially flawed ideals in caring for both nature as well as the arts, it is clear we need to reconsider practices of conservation and central concepts and motives that guide our work. This workshop brings together researchers from both domains for a fruitful cross-disciplinary dialogue on the challenges decision-making and the sustainable management of change.
