Hardwood forests rise from the flatland like islands in a sea of dry vegetation, and a plant called vinal sprouts thorns up to a foot long -- so destructive to livestock that Argentina once declared it a national plague. This is the Paraguayan Chaco, the Region Occidental: sixty percent of the country's landmass, watered by barely 400 millimeters of rain per year, home to indigenous nations whose presence predates any colonial map and Mennonite farmers who arrived less than a century ago.
