Work in the El Morro catchment was only possible with the generous collaboration of local farmers and ranchers. We are particularly indebted to Alberto Panza; the Rizzati, Uke, Bosco, Rodriguez, Comelli and Bridarolli families, and the late Coco Viotto who observed many of the ongoing changes with a sharp and curious eye (they can be “met” at the “Río Nuevo” documentary, available online). People at INTA, particularly Claudio Saenz, Mario Galván and Juan Cruz Colazo; and at the local government, specially Emiliano Colazo, helped us with their field experience. At the GEA lab, George Castellanos, Silvina Ballesteros, Raul Giménez, María Poca, and Tomás Milani provided valuable help and insight in the office and the field. Leonardo Ríos provided his geological experience in the area. Long field days with Alfonsina Tripaldi, Steve Loheide, Jeff McDonnell, Steve Forman, Coco Chiesa and Guillermo Ojeda were the source of many of the ideas presented here. We deeply acknowledge Deolinda Correa´s guidance in the first steps of this research plan. Grants from the Inter-American Institute for Global Change Research (IAI) SGP-HW 056 (GovernAgua Project), from FONCYT-Argentina (PICT2018-01216), CONICET (PUE 2016); as well as support from the REM AQUA network and Gobierno de la Provincia de San Luis; financed our work.
