Interesting facts about terraces (earthworks)

rice terraces

In agriculture, a terrace is a piece of sloped plane that has been cut into a series of successively receding flat surfaces or platforms, which resemble steps, for the purposes of more effective farming.

This type of landscaping is therefore called terracing.

Graduated terrace steps are commonly used to farm on hilly or mountainous terrain.

Machines such as tractors and chemical appliers aren’t used on terraces because of the structures’ highly irregular shapes. This lack of mechanized labor promotes traditional ways of living, such as farming small pieces of land with hand tools. Without machines and chemicals, terrace farming has a much lower carbon footprint than conventional farming.

Terrace farming is commonly used in Asia by rice-growing countries such as Vietnam, Philippines, and Indonesia.

Terrace farming is also commonly used in islands with steep slopes. The Canary Islands present a complex system of terraces covering the landscape from the coastal irrigated plantations to the dry fields in the highlands.

Apart from rice cultivation which is the most common, terraces are also used to grow wheat, barley, potatoes, and maize.

Terraced farming was developed by the Wari culture and other peoples of the south-central Andes before 1000 AD, centuries before they were used by the Inca, who adopted them.

The Inca built these terraced farms wherever mountain villages have existed in the Andes. They provided the food necessary to support the populations of great Inca cities and religious centres such as Machu Picchu.

The Banaue Rice Terraces are not part of the Rice Terraces of the Philippine Cordilleras. The terraces are occasionally called the “Eighth Wonder of the World”. It is commonly thought that the terraces were built with minimal equipment, largely by hand. The Banaue Rice Terraces are located approximately 1,500 metres (4,900 feet) above sea level. These 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 of the globe.
