1 CARRYING CAPACITY …the maximum number of people that an area of land (locally) can support. = ÷ Population carrying capacity Productive land Productive land per person

2 CARRYING CAPACITY …the maximum number of people that an area of land (locally) can support. = ÷ Population carrying capacity Productive land Productive land per person Consumption habits (local) Production yields ( local ) Short -distance quantity

3 CARRYING CAPACITY …the maximum number of people that an area of land (locally) can support. = ÷ Population carrying capacity Productive land Productive land per person ECOLOGICAL FOOTPRINT Productive land per person = ÷ Population Productive land Consumption habits (local) Production yields ( local ) Short -distance Consumption habits (local) Production yields ( global ) Long -distance quantity quantity …the amount of land (globally) each person requires.

4 Ecological footprint interface (appropriated carrying capacity) - Input: local consumption choices global production - Output: land usage (global hectares)

5 Ecological footprint interface (appropriated carrying capacity) - Input: local consumption choices global production - Output: land usage (global hectares) Carrying capacity interface - Input: local consumption choices local production - Output: population & land usage

6 Ecological footprint interface (appropriated carrying capacity) - Input: local consumption choices global production - Output: land usage (global hectares) Carrying capacity interface - Input: local consumption choices local production - Output: population & land usage

7 INPUTS Basic needs Time-scales Space-scales

8 FOOD: amount, meat-eggs, red meat, activity level, avoidable waste, recycling CLIMATE VARIABILITY, AGRICULTURE: organic farming, irrigation TEXTILES: amount, natural fibre, wool FUEL: liquid fuel, biofuel TIMBER, INFRASTRUCTURE, NATURE RESERVE INPUTS Basic needs Time-scales Space-scales

9 Short-term defaults INPUTS Basic needs Time-scales Space-scales

10 LESS: - meat - wastage - liquid fuel - infrastructure MORE: - physical activity - recycling - organics - timeframe - natural textiles - biofuel - timber - nature reserve Long-term defaults INPUTS Basic needs Time-scales Space-scales
