A related issue is the position of Scotland within the United Kingdom. It has been alleged that UK transmission pricing structures are weighted against the development of renewables, a debate which highlights the contrast between the sparsely populated north of Scotland and the highly urbanised south and east of England. Although the ecological footprints of Scotland and England are similar the relationship between this footprint and the biocapacities of the respective countries are not. Scotland's biocapacity (a measure of the biologically productive area) is 4.52 global hectares (gha) per head, some 15% less than the current ecological effect. In other words, with a 15% reduction in consumption, the Scottish population could live within the productive capacity of the land to support them. However, the UK ecological footprint is more than three times the biocapacity, which is only 1.6 gha head, amongst the lowest in Europe. Thus, to achieve the same end in the UK context, consumption would have to be reduced by about 66%.
