What will the world look like in 2050? How secure is your water supply? Can we all be consumers? When does waste become a resource? These are just some of the provocative questions posed by this collection of cards focused on why and how our world is changing. Conceived and designed by the Foresight, Innovation and Incubation team at Arup, the influential consulting firm that advises on all aspects of the built environment, this card set features seven topics that have been chosen as headings for further discussion: energy, waste, climate change, water, demographics, urbanization and poverty. The 189 cards are divided into five domains known as the STEEP framework: societal, technological, economic, environmental, and political. Each card represents a single driver of change-for instance urban migration, ageing population, austerity-along with a challenging and thought-provoking question. The flip side of the card provides pertinent data to expand on the question, as well as maps, graphs, and other illustrations. An accompanying booklet offers tips on how to use these cards independently or in a group setting. Whether brainstorming for new ideas or facilitating a discussion, these graphically sophisticated cards are an excellent resource for anyone interested in the future of technology, design and sustainability or indeed the way we might live in the years to come.
