ABSTRACT: The
objective is to describe the hydraulic infrastructure and social organization
in a small system of non-conventional irrigation locally known as presas. The technique consists in
controlling runoff and retaining the soil, which has dragged with it. For that
the local inhabitants must increase the height of a series of walls built with
stones arranged in beds of dry streams. The information was obtained with field
tours, interpretation of topographic charts and interviews with users of the presas. We conclude that the permanence
of the system depends on the knowledge to control runoff, the availability of
plant varieties adapted to the local ecology, the widespread use of oxen for
agricultural work, as well as the social arrangements that allow the
maintenance of the hydraulic infrastructure.
