The Paris Institute for Advanced Study (Paris IAS) and the Fondation 2100 in partnership with the Institute for Futures Studies are launching the first Positive Future competition in order to encourage the development and dissemination of mobilising imaginations that convincingly and realistically describe a liveable and desirable world. These are not utopian futures, but possible futures, the advent of which is based on scientifically, technically, socially and politically proven scenarios. Open to all and international in scope, this competition aims to stimulate alternative and hopeful discourses on the horizon of the century.
