This project envisioned three futures of San Francisco dominated by three notions of nature in the upcoming Data-ism age. Nature has always been the authority to justify landscape architecture design, and its definition changes all the time. When we are dealing with long-term issues, like climate change, our actions should be justified by the future notions of nature. The prediction of future nature notions is based on the theory of Data-ism. Full efficiency, holistic perception, and comprehensive understanding will be achieved with big data and the new technologies fueled by it. Accordingly, there will emerge new notions of nature: Nature as Eco-programme, Nature as Trans-reality and Nature as Post-humanity.
