Near Santa Cruz, Bolivia, the radial-pattern fields are part of a planned settlement scheme in a rainforest area. At the centre of each unit is a small community, which is surrounded by fields. A small buffer of forest separates the settlements from one another
Outside Bangkok, Thailand, rice fields fed by an extensive network of canals that is hundreds of years old appear as skinny rectangular fields. Some fields seem to be flooded (deep purple), which is part of the growing cycle of rice plants
South of Khartoum, Sudan, where the White and Blue Nile rivers join, a dizzying arrangement of irrigated fields stretches out across the state of El Gezira. Given the semi-arid climate of the surrounding area, this geometrical spectacle of fertile green fields depends on thousands of miles of canals and ditches that connect the region to the Blue Nile in the west. The man-made rivers and streams are part of an irrigation project called the Gezira scheme, which the British started in the colonial era to grow cotton for export back to Europe
