Detection of Agave angustifolia and Agave cupreata with geomatic techniques in Guerrero, Mexico. Cienc. Tecnol. Agropecuaria [online]. 2022, vol.23, n.2, e2241.  Epub 31-Abr-2022.

The agave plant has significant economic and cultural value, it is considered an agricultural and forestry product, and is also used in the production of a significant number of products. In Mexico, one of the most representative derivatives of agave are distilled beverages of mezcal and tequila, whose sales have increased outside the country. In response to this demand, Guerrero has reported an annual growth in production of 1.5 %, with an increase in area of more than 1,000 hectares between 2015 and 2020. This commercial boom has generated an expansion and intensification of planting and production of Agave spp. (Asparagaceae), as well as the use of inadequate agricultural production techniques and changes in traditional technology. That is why the objective of this work was to spatially locate the mezcal agave, in particular the species Agave cupreata Trel. & Berger and Agave angustifolia Haw., with geomatic technologies to identify the diversified environments of the agave (wild or cultivated) that strengthen the agro-productive processes and enhance the by-products of the crop. The study found that the potential area for agave cultivation is more than 25,000 hectares higher than that reported by official sources and that the calculations made with geomatic technologies have an accuracy of 91 % to identify suitable areas for the use and conservation of these two species of economic importance.
