Milpa is the term used in Central America for a system of shifting cultivation. This agricultural technique involves clearing a piece of land by cutting down trees and burning them, planting a variety of crops on the cleared field for one or more seasons, and then moving on to a new plot, leaving the old one to regenerate. This system is particularly noted for its role in growing maize (corn), beans, and squash together, which are staple crops in the region.

(b) Conuco is a term used in the Caribbean, not specifically Mexico, for a form of mixed cropping, and while it may involve some traditional practices similar to shifting cultivation, it's not exclusively identified with Mexico.
(c) Ladang refers to a form of shifting cultivation in Southeast Asia, particularly in countries like Indonesia and Malaysia, not Central Africa. Central Africa's shifting cultivation is more commonly referred to by other local names, depending on the specific region and country.
