In the valleys of the empire, irrigation farming was used. Dams diverted water from natural springs to ...
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.
Capping the top of the terrace was a layer of topsoil about 1 metre (3.3 ft) thick. The result was a terrace providing "well-drained rich soil and a level surface for growing crops." [9] At prestigious or royal sites, such as Machu Picchu, finely cut stone was used as the outer (visible) face of the retaining wall. The planting surface of an ...

These three radically different environments were all part of the Inca Empire (1438-1533 CE) and required different technologies for agriculture .
These changes made agriculture far more productive, supporting population growth, urbanisation, and increased stratification of society. The revolution was first described by the historian Antonio Garcia Maceira in 1876. [7] The name was coined by the historian Andrew Watson in an influential [5] [8] but at the time controversial 1974 paper.
Agriculture terraces were (and are) common in the austere, high-elevation environment of the Andes. Inca farmers using a human-powered foot plough. The earliest known areas of possible agriculture in the Americas dating to about 9000 BC are in Colombia, near present-day Pereira, and by the Las Vegas culture in Ecuador on the Santa Elena peninsula.
It has the fifth-largest amount of land used for rice cultivation in the world and is the world's largest exporter of rice. [46] Thailand has plans to further increase its land available for rice production, with a goal of adding 500,000 hectares to the 9.2 million hectares of rice-growing areas already cultivated. [ 47 ]
