Land use: how humans are using the land e.g. agriculture, urban culture
Land-use change: alteration of the landscape
impacts carbon sequestration and fire distribution
effect on biodiversity
increased dead zones due to fertilisers and pesticides
Control variables:
Global: Area of forested land as % of original forest cover
Biome: area of forested land as % of potential forest
