The ecological basis of the indigenous Nahua agriculture in the sixteenth century

The study of agriculture in ancient societies is of vital importance for the understanding of their ecological basis. This article discusses data gathered from Alonso de Molina's dictionary, published in Mexico City in 1571. Molina's information on soil, rain, plants, technology, and human labor applied to agricultural activities gives a picture of the complexity of the several native agricultural systems practiced at that time. Since the Sixteenth Century, native agriculture was impacted by the introduction of new plants, animals, agricultural equipment, and techniques from the Old World. A combination of the two agricultural models conform a new Mexican model of agriculture along the Colonial times. The knowledge of Sixteenth Century agricultural systems is fundamental for the understanding of the history and the conformation of contemporary agro-ecosystems. Recent studies on ecology and social anthropology agree on the necessity to take into account historical data for the discussion of ecological sustainability.
