Abstract

LANZELOTTI, Sonia  and  BUZAI, Gustavo. Spatial suitability models for prehispanic agriculture and current agriculture in the Santa María valley, Catamarca, Argentina. Estudios Socioterritoriales [online]. 2015, vol.18. ISSN 1853-4392.

This study was performed with the objective to identify suitable areas for development of pre-Hispanic and contemporary agriculture in Santa Maria Valley (Catamarca, Argentina) through the application of multicriteria evaluation techniques using Geographic Information Systems. The base map was based on data obtained from satellite images in combination with thematic maps specially prepared about geomorphological units, phytogeographic provinces, hydrography and areas with archaeological evidence of prehispanic agriculture. It was observed that the area with the greatest potential for agriculture is located in the piedmont sector of the Aconquija mountain, followed by the bottom of the valley. This pattern coincides mainly with the pre-Hispanic archaeological record, but not with the spatial distribution of existing farms. The relationship between society and nature, mediated through technology, is presented as the key to interpretation

Keywords : Suitability models; Pre-Hispanic agriculture; Multicriteria evaluation techniques.
