The Banaue Rice Terraces (Filipino: Hagdan-hagdang Palayan ng Banawe) are terraces that were carved into the mountains of Ifugao in the Philippines by ancestors of the indigenous people. They are frequently called the "Eighth Wonder of the World".[1][2][3] It is commonly thought that the terraces were built with minimal equipment, largely by hand. The terraces are located approximately 1500 metres (5000 ft) above sea level. They are fed by an ancient irrigation system from the rainforests above the terraces. It is said that if the steps were put end to end, it would encircle half the globe.[4]

Locals to this day still plant rice and vegetables on the terraces, although more and more younger Ifugaos do not find farming appealing, often opting for the more lucrative hospitality industry generated by the terraces[citation needed].[5] The result is the gradual erosion of the characteristic "steps", which need constant reconstruction and care. In 2010, a further problem was drought, with the terraces drying up completely in March of that year.[6]

The age of the terraces are believed by many to being over a 2,000 years old as postulated by anthropologist Otley Beyer. Several researchers however dispute this and contend that the terraces were built much later.[7][8]
