The theme of Doors 8 – ‘Infra’ – is indeed rather broad. Today we’ve posted a list of adjacent organisations and projects that we’ve learned about in developing the programme. Doors 8 is about collaborative innovation – not about charity, aid, or top-down development – so we have not listed that vast part of the NGO swarm. A priority in Delhi is to identify design challenges that are not already being tackled by someone else. The list of speakers begins that selection process – but the main work will be done, with you, at the event itself.
