Agricultural expansion and intensification	annual & perennial non-timber crops - agro-industry farming	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	hunting & collecting terrestrial animals - intentional use (species being assessed is the target)	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	dams & water management/use - abstraction of surface water (agricultural use)	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
