Nasa satellite images reveal the diversity of agricultural patterns as seen from space
Agricultural fields south-west of Perdizes, Brazil, photographed from the international space station. A mix of regularly gridded polygonal fields and circular centre-pivot fields mark the human land use of the region. Small tributary streams (and their adjacent floodplains) of the Araguari river extend throughout the agricultural landscape. The visual diversity of field forms is matched by the variety of crops produced here: sunflowers, wheat, potatoes, coffee, rice, soybeans and corn.
Resembling a work of modern art, variegated green crop circles cover what was once shortgrass prairie in south-western Kansas. The most common crops in this region are corn, wheat, and sorghum. Each of these crops is at a different point of development, accounting for the varying shades of green and yellow.
Sand dunes spill across the Snake River plain in Idaho. Freshly harvested fields line the southern boundary of the dunes, and to the north is a darker brush-covered lava plain.
