How is a global hectare used to measure demand – the footprint?
On the same tiny planet, if North Country consumes 75 kilos of the 100 kilos of AC (average crop) each year its demand is a total 3 (of four) global hectares of average crop – a per capita (cropland) footprint of 3/8 = 0.375 gha. South Country consumes only 25 kilos, so its (cropland) footprint is one of four hectares. Per capita, that’s 1/8, or a (cropland) footprint of 1/8 = 0.125 gha.
