At the meeting of the Gila Native Plant Society on Friday, November 16, 2018, George Farmer will give a talk entitled “Ollas: Ancient Irrigation - Past, Present and Future”. Olla irrigation has been in use for thousands of years. Chinese texts well over 2000 years old mention clay-pot irrigation. The Romans, too, used clay pots for irrigation. Olla irrigation can be found today in the Middle East, India, and Central and South America. It’s clear that olla irrigation has been used successfully across the planet. This begs the question: How does it work? What is the science behind the function? And how can it be used now, here in the Southwest, to conserve water, restore ecological habitats and successfully grow food? Free and open to the public. Refreshments following the program.
