Chimor
Subsistence and agriculture

The Chimú developed mainly through intensive farming techniques and hydraulic work, which joined valleys to form complexes, such as the Chicama-Moche complex, which was a combination of two valleys in La Libertad. The Lambayeque linked the valleys of La Leche, Lambayeque, Reque, and Saña Jequetepeque. They developed an excellent agricultural techniques which expanded the strength of their cultivated areas. Huachaques were sunken farms where land was withdrawn to work the moist, sandy soil underneath, an example of which is Tschudi.

The Chimú used walk-in wells, similar to those of the Nazca, to draw water, and reservoirs to contain the water from rivers. This system increased the productivity of the land, which increased Chimú wealth, and likely contributed to the formation of a bureaucratic system. The Chimú cultivated beans, sweet potato, papaya, and cotton with their reservoir and irrigation system. This focus on large-scale irrigation persisted until the Late Intermediate period. At this point, there was a shift to a more specialized system that focused on importing and redistributing resources from satellite communities. There appears to have been a complex network of sites that provided goods and services for Chimú subsistence. Many of these sites produced commodities that the Chimú could not.

Many sites relied on marine resources, but after the advent of agriculture, there were more sites further inland, where marine resources were harder to attain. Keeping llamas arose as a supplemental way of attaining meat, but by the Late Intermediate period and Late Horizon, inland sites used llamas as a main resource, although they maintained contact with coastal sites to use supplemental marine resources. They also made masks.
