For Sustain & Decay, we invite researchers, design practitioners, and artists to investigate data for sustainable development and to think about effective and provocative ways to represent complex interdependencies within and between ecological, socio-technical, political, and urban systems, as well as other types of interfaces between dynamic systems. An example of such interdependencies is what Prof. Hausmann calls the “collective knowhow” of countries and regions. He argues that this knowhow is an important building block of the wealth of nations, and that data collection and data visualization can help to identify feasible and effective paths for economic progress, which can be used to orient the efforts of both the public and private sector. In parallel, two years ago more than 190 world leaders committed to seventeen SDGs, including eradicating extreme poverty, fighting inequality and injustice, and fixing climate change. New explorations of the use of data and visualization will play a considerable role in achieving these highly interdependent goals. In addition, we encourage submissions to focus on the myriad relationships between process and artifact. What are the creative and practical processes that are required to produce data-driven interactive artworks, visualizations, and installations? We are interested in how submitted works can influence and transform the way we understand the world around us, but also in how the design processes that go into the creation of these works can influence the way we perceive and understand them. Sustain & Decay took place in Phoenix, Arizona in October 2017, and featured work by Ozge Samanci, Adriene Jenik, Giorgia Lupi, and many others.
