Waru waru fever

Traditional Inca waru waru farming technologies and techniques appear have the potential to triple food production:

Potatoes and grains such as quinoa are grown in the elevated earth, while underwater ferns in the canals provide a home for nitrogen-rich green algae that provide a natural fertilizer. The water in the canals allows for ``splash irrigation'' and even creates a slightly warmer micro-climate that protects crops from the killer frost of the harsh altiplano nights. By absorbing the strong equatorial sunlight during the day, the water retains enough solar radiation to raise overnight temperatures by nearly 4 degrees Fahrenheit.
