We will analyze and compare the evolution of individual irrigation VS collective irrigation based on the economic and technical orientation nomenclature (Orientation technico-économiques “OTEX”), taking into account the irrigation technique (aspersion, micro-irrigation) and the farmland acreage (superficie agricole utilisée “SAU”). The first study carried out at the scale of the Languedoc-Roussillon region, solely using OTEX, did not enable the identification of clear explanatory factors. We wish to diversify this “second” analysis and perhaps proceed with factorial analysis to be able to identify these “missing” explanatory factors.
