The Banaue Rice Terraces are 2000-year old terraces that were carved into the mountains of Ifugao in the Philippines by ancestors of the indigenous people. The Rice Terraces are commonly referred to by Filipinos as the "Eighth Wonder of the World". It is commonly thought that the terraces were built with minimal equipment, largely by hand. The terraces are located approximately 1500 meters (5000 ft) above sea level and cover 10,360 square kilometers (about 4000 square miles) of mountainside. They are fed by an ancient irrigation system from the rainforests above the terraces. It is said that if the steps are put end to end it would encircle half the globe.
Contrary to popular belief, the Banaue Rice Terraces are not part of the Rice Terraces of the Philippine Cordilleras UNESCO inscription but are declared a National Cultural Treasure as the Ifugao Rice Terraces. Ancient sprawling man-made structures from 2,000 to 6,000 years old, other terraces are found in the provinces of Kalinga, Apayao, Benguet, Mountain Province and Ifugao. But only those in Batad, Bangaan, Mayoyao, Hungduan and Nagacadan, all in Ifugao, are inscribed as a UNESCO World Heritage Site.
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 Rice Terraces. 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.
