Along a typical river in Bali, small groups of farmers meet regularly in water temples to manage their irrigation systems. They have done so for a thousand years. Over the centuries, water temple networks have expanded to manage the ecology of rice terraces at the scale of whole watersheds. Although each group focuses on its own problems, somehow everything works out in a way that optimizes rice harvests for the farmers in dozens of villages. How is this possible? Google Earth reveals transitory patterns in the rice paddies that closely resemble phase transitions in physics, like the onset of magnetism. This unlocked a story of hidden order that charms physicists, perplexes economists and offers everyone a startlingly new way to think about how people can interact with nature.
