Nazca Scoops Mystery Answered?
Swales are used here in the Desert Southwest, as well. These scoops can capture water from precious rains and prevent rain from just washing away on the hard-baked earth.
Above is a photo of the swales in Niger, an area of North Africa that is turning desert transition over to green again.
It reminded me of something else -
These scoops (above) go on for many miles in Nazca, Peru. Perched atop a ridge line, they are ideal for capturing rains. Was their purpose similar to the permaculture project in Niger, Africa?
I leave y'all to contemplate that one!
