In this public lecture, Isabel Dedring presented new ideas for strategic, long term planning in cities against the backdrop of the London Infrastructure Plan 2050. Isabel, who formerly served as the Mayor of London’s Deputy Mayor for Transport and is currently Arup’s Global Transport Leader, combined the London experience with new insights from cities globally. The lecture focused on questions of integrating land use, urban form and infrastructure provision, while addressing the political tension between short term election cycles and the continuity required for long term planning.
