    • Distribución espacial y controles ambientales de las represas (tajamares) en el Chaco Árido 

      Niborski, Marcos Javier; Murray, Francisco; Jobbagy Gampel, Esteban Gabriel; Nosetto, Marcelo Daniel; Fernandez, Pedro David; Castellanos, George; Magliano, Patricio Nicolás (Asociación Argentina de Ecología, 2022-02-24)
      Las regiones áridas tienen déficit hídrico a lo largo de todo el año, lo cual limita el crecimiento de la vegetación y la provisión de agua para bebida animal. El Chaco Árido (~10 Mha) sostiene una producción ganadera ...

    • Modeling Rainwater Harvesting and Storage Dynamics of Rural Impoundments in Dry Chaco Rangelands 

      Niborski, Marcos Javier; Martin, Osvaldo Antonio; Murray, Francisco; Jobbagy Gampel, Esteban Gabriel; Nosetto, Marcelo Daniel; Paez, Ricardo Andrés; Magliano, Patricio Nicolás (MDPI, 2023-06)
      Transporting water to supply livestock is one of the great challenges of the drylands. Ranchers usually make impoundments, filled by runoff, to access freshwater for cattle supply in flat rangelands. The aim of this study ...

    • Productive performance of alternative land covers along aridity gradients: ecological, agronomic and economic perspectives 

      Murray, Francisco; Baldi, Germán; Bernard, Tamara von; Viglizzo, Ernesto Francisco; Jobbagy Gampel, Esteban Gabriel (2016-11)
      The replacement of natural vegetation by pastures and extensive crops is generally driven by economic incentives and supported by technology improvements and multiple subsidies. However, towards areas of increasing aridity ...

    • Rainwater harvesting in Dry Chaco: Regional distribution and local water balance 

      Magliano, Patricio Nicolás; Murray, Francisco; Baldi, Germán; Aurand, Santiago Javier; Páez, Ricardo Andrés; Harder, Wilbert; Jobbagy Gampel, Esteban Gabriel (2015-12)
      Rainwater harvesting (RWH) has been essential for the establishment of human settlements in many dry regions of the world that lacked suitable surface or groundwater resources. A vast fraction of the South American Dry ...

    • Represas puntanas: Acceso, gestión y gobernanza del agua en las tierras áridas de San Luis 

      Magliano, Patricio Nicolás; Niborski, Marcos Javier; Murray, Francisco; Heider, Guillermo; Petit, María Victoria; Calderón Archina, Aldana; Ballesteros, Silvina I.; Paez, Ricardo Andrés; Jobbágy, Luis; Milani, Tomás (Asociación Argentina de Ecología, 2024-08)
      Los pobladores de la llanura árida del noroeste de San Luis cosechan agua de lluvia en pequeñas represas (tajamares) para producir ganado bovino y caprino en bosques nativos. Esta es una tecnología antigua que en las últimas ...

    • Soil physical changes after conversion of woodlands to pastures in dry Chaco rangelands (Argentina) 

      Magliano, Patricio Nicolás; Fernandez, Roberto J.; Florio, Eva Laura; Murray, Francisco; Jobbagy Gampel, Esteban Gabriel (2017-03)
      The conversion of dry woody rangelands into pastures can alter key soil physical properties that regulate ecosystem water circulation and storage. Based on three paired stands of native woodlands and pastures established ...

    • South American Dry Chaco rangelands: Positive effects of cattle trampling and transit on ecohydrological functioning 

      Magliano, Patricio Nicolás; Breshears, David D.; Murray, Francisco; Niborski, Marcos Javier; Nosetto, Marcelo Daniel; Zou, Chris B.; Jobbagy Gampel, Esteban Gabriel (Wiley, 2022-12)
      Livestock production in drylands requires consideration of the ecological applications of ecohydrological redistribution of water. Intensive cattle trampling and the associated increase of surface runoff are common concerns ...

    • Vegetation Productivity in Natural vs. Cultivated Systems along Water Availability Gradients in the Dry Subtropics 

      Baldi, Germán; Texeira González, Marcos Alexis; Murray, Francisco; Jobbagy Gampel, Esteban Gabriel (2016-12)
      The dry subtropics are subject to a rapid expansion of crops and pastures over vast areas of natural woodlands and savannas. In this paper, we explored the effect of this transformation on vegetation productivity (magnitude, ...
