Oliver Kellhammer is a land artist, permaculture teacher, activist and writer. His botanical interventions and public art projects demonstrate nature’s surprising ability to recover from damage. Lately, his work has focused on cleaning up contaminated soils, reintroducing prehistoric trees onto landscapes damaged by industrial forestry and cataloguing the biodiversity of brownfields. Climate change is a major area of concentration and he is part of the ‘Dear Climate’ initiative along with Una Chaudhuri, Fritz Ertl and Marina Zurkow, all of NYU, who investigate the psychosocial aspects of anthropogenic climate change through a variety of media. (www.dearclimate.net) Recent writings include ‘Neo Eocene’, published in Making the Geologic Now, edited by Jamie Kruse and Elisabeth Ellsworth (Punctum 2012) and ‘Violent Reactions’ in Marina Zurkow’s Petroleum Manga (Punctum 2014). He divides his time between rural British Columbia and Alphabet City and is a part-time lecturer in sustainable systems at Parsons.
