By 2050 there will be five billion urbanites but, with pressure on resources and climate disruption, how will cities cope? New technology and conceptual design will be vital, says Emma Stewart, head of sustainability solutions at Autodesk.

“If we play our cards right, the 2050 city will:

  • recognise its context, situated within a natural and agricultural ecosystem that provides its denizens’ abundant raw materials, free crop pollination, and genetic diversity;
  • be resilient, responding to long-term shifts through adaptive re-use and short-term shocks through high-tech smart devices and low-tech biomimetic designs;
  • be water neutral, drawing from its aquifers only as much as it can recharge, and the rest from the sky or recyclers now part of basic plumbing;
  • be inhabited by citizens who emit no more than one ton of greenhouse gases per person per year, due to their heavy reliance on efficient building design, decentralised generation, district energy systems, and multi-modal transit.”
