First of all, it is very important to point out that, evidently, prior to the field work, we were physically present in the following municipalities, all of them belonging to the state of San Luis Potosi; that is, Xilitla, Real de Catorce and Ciudad Valles. However, the available information and the information that was available was so vast that, of course, various lines of research were formed, all of them showing an unusual interest among the members of the project; however, it was necessary to opt for the one that had the greatest specific weight for the research itself: coffee growing. It should be noted that the decision was based on the research budget. The person in charge of the present research project is fully aware that, at another opportunity or under another project, it will be possible to venture into one of the various lines of research that are, for the time being, pending.
