Ancient Agricultural Systems Provide Sustainability Model

One author of a paper published in World Archaeology writes on The Conversation that lessons from some past agricultural systems could help make agriculture more sustainable today. One example is the pre-Incan system called Waru Waru, which utilizes raised beds surrounded by water channels to manage water and moderate the local climate, as well as raise fish alongside crops. Waru Waru is particularly resilient to both flooding and drought. Another strategy practiced since ancient times is fish-rice farming, in which fish in the rice fields help control pests and increase rice yields as well as providing an additional protein source.
