Carved into the mountains of Ifugao in the Philippines by ancestors of the indigenous people, the Banaue Rice Terraces also known as Payew, are 2000-year old terraces known to be 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. Rice and vegetables are planted on the terraces by the people, although more and 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.
Ifugao rice terraces were declared free from Genetically Modified Organism (GMO)in March, 2009. An event was organized in Dianara Viewpoint for this announcement where it was graced by Gov. Teodoro Baguilat, Mayor Lino Madchiw, Greenpeace campaigner for Southeast Asia Daniel Ocampo, and Cathy Untalan who was executive director of the Miss Earth Foundation. Before the announcement ceremonies, 3 Mumbakis performed an Alim, a tribal ritual to ask for blessings where an animal is offered to the gods.
Many terraces are found in the province of Ifugao and the Ifugao people have been its caretakers. Ifugao culture is basically woven around rice and the culture displays an elaborate array of rice culture feasts linked with agricultural rites from rice cultivation to rice consumption. Harvest season generally calls for thanksgiving feasts while the concluding harvest rites tungo or tungul (the day of rest) entail a strict taboo of any agricultural work. Partaking of the bayah (rice beer), rice cakes, and betel nut constitutes an indelible practice during the festivities and ritual activities.
The Ifugao people spend most of their labor at their terraces and forest lands while occasionally tending to root crop cultivation. The Ifugaos have also been known to culture edible shells, fruit trees, and other vegetables which have been exhibited among Ifugaos for generations. Indigenous rice terracing technologies have been identified with the Ifugao’s rice terraces such as their knowledge of water irrigation, stonework, earthwork and terrace maintenance. As their source of life and art, the rice terraces have sustained and shaped the lives of the community members.
Aside from the Banaue Rice terraces there are 4 other similar terraces, the Batad Rice Terraces, Mayoyao Rice Terraces in Mayoyao, Hapao rice terraces and Kiangan rice terraces. The Batad rice terraces are located in Barangay Batad in Banaue, which resemble an amphitheatre. The Mayoyao rice terraces are for a rice variety called tinawon, a rare type of organic rice which is grown in red and white variety in these terraces. The Hapao rice terraces are located in Hungduan, these terraces are stone-walled and date back to 650 AD. The Kiangan rice terraces is similarly located in Banaue, here they grow the rice varieties of nagacadan and julungan.
Apart from rice, the locals have found another way of living; tourism. The Tourism industry has developed a number of activities for visitors which may include the traditional sightseeing of the terraces and visits to the tribes at the foot of the terraces. A Mumbaki meaning traditional Ifugao witch doctor is also recommended to visitors, these doctors can perform spiritual healing rituals.
