How do farmers deal with wasted acreage at the corners of their crop circles?
Some add corner systems, so water sprayers can reach the otherwise untouched land at the edges of the sprayers' reach. But as Edible Geography points out, "ecologists are preaching the potential of pivot corners. In a simplified landscape of monoculture crop circles, the corners can restore complexity: left as native perennial grassland or managed as early successional habitat, these concave triangles can provide valuable habitat for bees, birds, and predatory insects to support crop pollination and natural pest control." A short look at the costs and benefits of pivot discards.

A viilage to reinvent the world : Gaviotas "In 1965 Paulo Lugari was flying over the impoverished Llanos Orientales, the “eastern plains” that border Venezuela. The soil of the Llanos is tough and acidic, some of the worst in Colombia. Lugari mused that if people could live here they could live anywhere.....The following year Lugari and a group of scientists, artists, agronomists and engineers took the 15-hour journey along a tortuous route from Bogota to the Llanos Orientales to settle."
"...they would need to be very resourceful. So they invented wind turbines that convert mild breezes into energy, super-efficient pumps that tap previously inaccessible sources of water [powered by a child's playground seesaw!], and solar kettles that sterilize drinking water using the furious heat of the tropical sun....They even invented a rain forest!" (from "Gaviotas - A village to reinvent the World"
, by Tim Weisman) Amidst the strife of war torn Columbia, Gaviotas persists and even flourishes
" "When we import solutions from the US or Europe," said Lugari, founder of Gaviotas, "we also import their problems."....Over the years Gaviotas technicians have installed thousands of the windmills across Colombia
....Since Gaviotas refuses to patent inventions, preferring to share them freely, the design has been copied from Central America to Chile."
Gaviotas is real
, yes, but it is also a state of mind
- as if Ben Franklin, Frank Lloyd Wright, Leonardo Da Vinci - all of the great those giants who reinvisioned the possible
- were reincarnated : as a small Columbian village on a once-desolate plain. "Colombian novelist Gabriel Garcia Marquez has called Paolo Lugari the "inventor of the world." "
