Answer:
indigenous peoples in the Americas created a variety of agricultural systems that were suited to a wide range of environments, from southern Canada to southern South America and from high elevations in the Andes to the lowlands of the Amazon River. Agriculture arose independently in at least three regions: South America, M-e-s-o-america, and eastern North America. Although the Americas had several indigenous animal species that were domesticated, none were of an appropriate size or temperament for use as draft animals; as a result, the plow and other technology reliant on heavy traction were unknown.
Sweden production, also known as slash-and-burn agriculture, was practiced from temperate eastern North America to the tropical lowlands of South America. Field fertility in Sweden systems resulted from the burning of trees and shrubs in order to add nutrients to the soil. Such systems had high ecological diversity, thus providing a range of resources and prolonging the usefulness of what would otherwise have been short-lived fields and gardens. Settlements moved when productivity significantly declined and firewood was in low supply.
