Sustainable lifestyles to inform development & masterplanning
Aim of my talk What is sustainable? How sustainable lifestyles inform masterplanning
The Challenge Kofi Annan, former UN Secretary General, 2001. Our biggest challenge this new century is to take an idea that seems abstract sustainable development and turn it into a reality for all the world s people
Origins of Eco-footprinting human consumption - food, materials & energy can be converted in areas of biologically active land required to produce them Examples: Per annum 25 hectares of fishing grounds / tonne of fish 1.3 hectares of forest / m 3 timber 0.35 hectares forest / tonne CO 2 from fossil fuels
Planet Earth s Productive Capacity cropland 1.3 billion hectares grazing land 4.6 forest 3.3 fishing grounds 3.2 built up areas 0.2 TOTAL 12.6 billion hectares
Global Biocapacity versus Consumption
Bringing it home global target - 1.9 hectares per person UK footprint 6 hectares per person + + =?

Solar orientation as a driver for masterplanning? Do you save energy by facing south? East-west light for wellbeing? Solar acess for public space and gardens? Are other drivers more important such as making streets legible and make local shops work well?
