Squealed to a stop to examine a driveway that has turned into a promise... Bulbs: tulips, daffodils. These will come every spring forever.
In ancient times the Incas fed an empire with marginal land utilizing sustainable farming techniques—even managing to store 3-5 years worth of extra food in case drought, hail or frost ruined a year's crops. Today, The Seedling Project is working to record current farming methods as passed down through generations.
The researchers concluded that these beginnings in plant domestication “served as catalysts for rapid social changes that eventually contributed to the development of intensified agriculture, institutionalized political power and towns in both the Andean highlands and on the coast between 5,000 and 4,000 years ago.”
The evidence at Ñanchoc, Dr. Dillehay’s team wrote, indicated that “agriculture played a more important and earlier role in the development of Andean civilization than previously understood."
