Steve Lansing, a senior fellow at the Stockholm Resilience Centre, is helping preserve the centuries-old water-temple system in Bali that distributes water from a volcanic lake to over two hundred farming villages. Lansing and landscape architect Julia Watson are working with the people of Bali to craft a plan to enable tourists to explore the area and preserve it. Watson says the idea is to protect “the most resilient system and the most bio-diverse agro ecosystem known to man.”

Watch now: Steve Lansing, a senior fellow at the Stockholm Resilience Centre, discusses the Byzantine system for the distribution of water from a volcanic lake in Bali to over two hundred farming villages. It’s worked since the 12th century, it’s egalitarian and it’s still-sustainable. “It’s one of the few functioning, ancient democratic institutions that we know about. It’s kind of beautiful.”
