The Human Impacts Database

A collection of useful numbers for quantifying the impacts of the human presence on Earth.

This quantity is a single measurement of the quantity at a given point in time (2001 — 2015).


Value:		(0.2 ± 0.1) × 10¹⁰ m² / yr see this value in other units This is equivalent to... (0.2 ± 0.1) × 10⁴ km² / yr (0.2 ± 0.1) × 10⁶ Ha / yr
HuID:		19429
Relevant Year(s):		2001 — 2015
Summary:		The amount of forest area disrupted globally in 2015 due to expanding urbanization. Forest area disruption due to urbanization is defined as "forest and shrubland conversion for the expansion and intensification of existing urban centers."
Method:		Value is calculated from map based measurements that commodity-driven deforestation is ≈ 5 MHa/yr accounting for 25% of all forest disruption (see HuID: 96098 ) and that 0.6 ± 0.3 % of all forest disruption comes from urbanization. Uncertainty represents a 95% confidence interval. See Table 11 and Figure 3 of source material.
