In recent decades, the oasis of Mendoza and San Juan (Argentina) has been dramatically transformed into the heat of agro-exporting restructuring that took place under the current neoliberal corporate agro-food regime. These processes are only the culmination of a long history of integration into the development of capitalism as an ecology-world. In this way, we intend, from this hybrid, cross-border and relational approach, to historically rebuild the fragmented spatial trajectory of the main Cuyan oasis from their prehispanic origin to their articulation in three successive agri-food regimes. Secondly, we intend to describe the recent expansion of the agricultural border through the uncontrolled use of groundwater reserves under the last regime. We highlighted the relational processes that, based on the ecological/world approach, are at the basis of the production and marketing of three emblematic goods in these oases: wine, olive oil and pre-fried potatoes. The methodology we adopted was aimed at describing historical oasis trajectories using a selection of documentary sources and regional literature. One of the main findings was that the third agri-food regime allowed agro-industrial oasis to expand goods borders further. This was based on the systematic exploitation of groundwater, which until now was essentially complementary to the surface source. In this neoliberal framework, precision farming makes it possible to monitor the key stages of the production process on the basis of standardised criteria of international demand for quality and quantity. In conclusion, we understand that access to cheap nature sources (be it water, soil or human work) not only enabled the production of goods that can be used in demanding global markets, but also reshaped the water management model itself from a more state-oriented and socially conditional one to a more privatised, telecontrolled and autonomous one. However, these processes of expansion of the goods border are conditioned by local elements specific to pre-existing socio-ecological dynamics, which is why this border often faces insurmountable boundaries.
