Points noted

  • Elimination of emissions
  • Planet is rapidly urbanising
  • The idea of refining clean energy is not an option for counter acting climate change
  • Solution lies in enhancing cities
  • Denser cities
  • New eco districts
  • creating all new sustainable neighbourhoods
  • infill development
    Infill development is the process of developing vacant or under-used parcels within existing urban areas that are already largelydeveloped. Most communities have significant vacant land within city limits, which, for various reasons, has been passed over in the normal course of urbanization.
  • “reweaving the urban fabric that we already have” Alex Steffen
  • We want the access of the capacity of things – surplus capacities
  • Urban Retrofitting e.g.

  • Green infrastructure
  • pollinator pathways
  • Soil and Carbon Sequestration
  • “At present we are stealing the future, selling it in the present, and calling it GDP(gross domestic product).” Paul Hawking

Seen both of is Ted Talk now and I am totally inspired. Next step is to read his book Worldchanging: a guide for the 21st century
