Table 4 Included land-use harmonization (LUH) variables.

From: Land-use change is associated with multi-century loss of elephant ecosystems in Asia

States (units: fraction of grid cell)

Transitions between land use states (units: fraction of grid cell per year)

Management—irrigation (units: fraction of crop area)

primf: forested primary land

primf_harv: wood harvest area from primary forest

irrig_c3ann: irrigated fraction of C3 annual area

primn: non-forested primary land

primn_harv: wood harvest area from primary non-forest

irrig_c3per: irrigated fraction of C3 perennial area

secdf: potentially forested secondary land

secmf_harv: wood harvest area from secondary mature forest

irrig_c4ann: irrigated fraction of C4 annual area

secdn: potentially non-forested secondary land

secyf_harv: wood harvest area from secondary young forest

irrig_c4per: irrigated fraction of C4 perennial area

pastr: managed pasture

 

irrig_c3nfx: irrigated fraction of C3 nitrogen-fixing area

c3ann: C3 annual crops

 

flood: flooded fraction of C3 annual crop area

c3per: C3 perennial crops

  

c4ann: C4 annual crops

  

c4per: C4 perennial crops

  

c3nfx: C3 nitrogen-fixing crops

  
  1. Note that although wood harvest rates are labelled as “transition” variables representing land-use conversions between years, they quantify the percentage of a pixel harvested within a given year and so can be used alongside the other two types of annual layers.
