The research project asks: how critical design and theory practices help to understand the long history of environmental data in the context of current digital culture? DAfED focuses especially on the space, geography, and topology of environmental data. In other words, environmental data is read in relation to the sites of emergence, distribution, and control of data as it becomes understood as spatial, architectural, and landscape-scale dynamic. From a focus on energy islands to theorising and developing “planetary gardens” the project deals with different scales of inquiry with the aim of not only developing new insights into what is environmental data in a recursive spatially located context, but what are the critical and creative methods that help us to read this spatial context.
