Populated Irrigated Cropland

The Populated Irrigated Cropland anthrome has a minor human population and expansive agricultural lands.  Variations in climate require much of this anthrome to be irrigated in order to support the agricultural use of this land.  A mix of forest and pasture take up the remainder of this anthrome though not with any great area thus land use and land cover falls into a variety of smaller categories.

Found all over the world the populated irrigated cropland anthrome is not even specific to a broad conventional biome category as it can be found in grasslands, forests, and deserts.  This illustrates how humans transform their environments to suit their needs, in the case of this anthrome, more cropland was achieved by extensive irrigation.
