Ichma, Ychma, Yschma, Ychsma, Ichmay, Irma, Izma, Ishmay or Ishma (old Quechua for cinnabar, vermilion, crimson color) was a pre-Inca indigenous polity later absorbed by the Inca Empire and reorganized as a wanami (province). For the Inca it was known as Pachakamaq (Pachacamac), rather than its original name of Ishma. Despite occupying a desert, the inhabitants of Ishma had a high standard of living, thanks to their expertise in devising multiple irrigation channels as far as the river waters could reach, to give life to an extensive orchard and forest.
