Built Land Footprint

This component includes all areas that have been built on, for example industrial sites, roads and houses. The built land ecological footprint for the South West in 2001 was 1.3 million gha (0.26 gha per person). This accounted for 5% of a South West resident's ecological footprint. The built land type with the largest ecological footprint was commercial/industrial (incl. hydro) with 0.12 gha per person. Table 10 shows a breakdown of the built land ecological footprint, by land use.

The built land ecological footprint is affected by several factors:

  • Population size;
  • Local land types and uses;
  • Bioproductivity;
  • How much area is available; and
  • Efficiency of land use, for example dense urban living compared to suburban sprawl.

The average UK built land ecological footprint is 0.32 gha per person, whereas due to its rural nature, the South West's built land ecological footprint per person is considerably smaller.
