The Human Impacts Database

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

This quantity comes from a time series measurement and the most recent value (2015) is reported.


Value:		(5.7 ± 1.1) × 10¹⁰ m² / yr see this value in other units This is equivalent to... (5.7 ± 1.1) × 10⁴ km² / yr (5.7 ± 1.1) × 10⁶ Ha / yr
HuID:		96098
Relevant Year(s):		2015
Summary:		The global area deforested in 2015 due to commodity-driven deforestation. Deforestation is defined as involving "abrupt transition from land with trees to land without trees with no subsequent regrowth." Commodity-driven deforestation is defined "by the long-term permanent conversion of forest and shrubland to a nonforest land use such as agriculture (including oil palm), mining, or energy infrastructure.
Method:		The value of 5 MHa/yr is reported in second paragraph on page 1112 of the source and is apparent in Fig. 3 A. Commodity driven deforestation is 27 ± 5 % of total forest loss. Uncertainty represents a 95% confidence interval.
