Urban planning: Ecofying Cities

TED Studies, created in collaboration with Wiley, are curated video collections — supplemented by rich educational materials — for students, educators and self-guided learners. In Ecofying Cities, speakers reveal ideas about sustainable development (and redevelopment) that aren't all about setting limits, going without or preparing for the worst. Rather, they find solutions in resourceful, hopeful, beautiful communities. Relevant areas of interest, study and coursework include: urban renewal, new urbanism, architecture, economic development, green building, transportation planning, alternative energy production, environmental justice, civil engineering, environmental engineering and biomimicry.

Learning outcomes

TED's Ecofying Cities will provide learners with a deeper understanding of:

  • The basic goals of sustainable urban design
  • The city as an ecological system
  • How energy generation can be thought of as a design problem and how waste can be thought of as a potential resource
  • Why density is such an important concept for urban design and how density affects people’s behavior
  • How cities of the future might address the challenges of climate change and reliance on fossil fuels
  • How retrofitting and reuse can improve the usability of cities and invigorate public spaces at an urban scale
  • The challenges of improving and ecofying our cities so that resources are distributed more fairly and so that cities and buildings reflect our values and provide a meaningful sense of place.
