Abstract

ANDRADE-MARTINEZ, Everardo et al. Identification of Suitable areas for rainfed agriculture with maize and beans in the Basin of Autlán, Jalisco, México. Rev. Geog. Amer. Central [online]. 2019, n.62, pp.1-32. ISSN 2215-2563.  http://dx.doi.org/10.15359/rgac.62-1.1.

Currently, there is little research on the identification of areas suitable for implementing rainfed agricultura activity using corn and bean crops in the basin of Autlan. To delimit suitable surfaces in the area of study, a multicriteria methodology (Analytical hierarchical Process) and the Geographic Information Systems were implemented, using information from semi-structured surveys as the main source. The parameters obtained meet the ideal conditions of soil and climate to cultivate maize and beans in surfaces with rainfed agriculture activity, identifying suitable areas in the 38.08 por ciento of the total surface area of the basin. For the 14.23 por ciento it is suggested to implement agriculture with practices of soil and water conservation, taking into account the existing increase in the slope of the terrain and the presence of shallow soils; these characteristics can increase the risk of erosion. The remaining area should be identified as a zone of protection as it is distributed in mountain areas.

Keywords : Multicriteria analysis; prioritization; rainfed agriculture.
