Ackroyd & Harvey create multi-disciplinary works that intersect art, activism, biology, ecology and history. Referencing memory and time, nature and culture, urban political ecologies and biosphere degradation, their time-based practice reveals an intrinsic bias towards process and event. Processes of germination, growth and decay (organic and inorganic), feature in artworks that often evolve through extended research in response to people and place, interfacing their interest in local ecologies and global environmental concerns. They have exhibited worldwide in contemporary art galleries, museums, public spaces and sites of special interest. In 2019, they co-founded Culture Declares Emergency in response to the climate and ecological emergency.
