English: Along the banks of this river, roughly 100 kilometres inland from where the river empties into the Atlantic Ocean, irrigation projects take advantage of water from the river and soils from the floodplains to grow produce, turning parts of a normally earth-toned landscape emerald green. A network of bright rectangles of varying shades of green contrasts with surroundings of grey, beige, tan, and rust. Immediately south of a large collection of irrigated plots, faint beige circles reveal centre-pivot irrigation fields apparently allowed to go fallow.
