Grassland based systems (LG): A subset of solely livestock systems in which more than 10% of the dry matter fed to animals is farm produced and in which annual average stocking rates are less than 10 LU per hectare of agricultural land. Three sub-categories are recognised, based on the ecosystem where they are practised:
Temperate and tropical highland grassland based systems (LGT)
Humid/subhumid tropics and subtropics grassland based systems (LGH)
Arid/semi-arid tropics and subtropics grassland based systems (LGA)
