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 ... -
The ecohydrology of ecosystem transitions: a meta‐analysis
Viglizzo, Ernesto Francisco; Nosetto, Marcelo Daniel; Jobbagy Gampel, Esteban Gabriel; Ricard, Maria Florencia; Frank, Federico Carlos (Wiley, 2015-07)A vast body of literature demonstrated that anthropogenic disturbances such as overgrazing and fire are key drivers of abrupt transition between vegetation types in ecosystems. In this study, we propose that the hydrological ... -
Flujos de agua y energía en los últimos cuarenta y dos años de agricultura en Argentina
Frank, Federico Carlos (Universidad Nacional de Mar del Plata, 2014-03-03)Una manera relevante de describir procesos ecológicos es a través del análisis de los flujos de agua y energía. Estos dos recursos son, probablemente, los insumos de mayor importancia para la agricultura en Argentina. La ... -
Hydrological and productive impacts of recent land use and land cover changes in the semiarid Chaco: understanding novel water excess in water scarce farmlands
Giménez, Raúl; Mercau, Jorge Luis; Bert, Federico Esteban; Kuppel, Sylvain; Baldi, Germán; Houspanossian, Javier; Magliano, Patricio Nicolás; Jobbagy Gampel, Esteban Gabriel (Wiley, 2020-08)Over the last decades, the rapid replacement of native forests by crops and pastures in the Argentinean semiarid Chaco plains has triggered unprecedented groundwater level raises resulting from deep drainage increases, ... -
Interacción de controles humanos y ambientales sobre la ecología y socio-economía de sistemas productivos semiáridos del Chaco y Espinal
Murray, Francisco (Universidad de Buenos Aires, 2017-04-01)El avance agrícola hacia regiones de mayor aridez crece en todo el mundo y particularmente en Sudamérica, generando cuestionamientos sobre su viabilidad productiva, sus costos ambientales y beneficios socio-económicos. ... -
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 ... -
Partition of some key regulating services in terrestrial ecosystems : meta-analysis and review
Viglizzo, Ernesto Francisco; Jobbagy Gampel, Esteban Gabriel; Ricard, Maria Florencia; Paruelo, José María (Elsevier, 2016-08)Our knowledge about the functional foundations of ecosystem service (ES) provision is still limited and more research is needed to elucidate key functional mechanisms. Using a simplified eco-hydrological scheme, in this ... -
Plants vs. Streams: Their groundwater‐mediated competition at “El Morro”, a developing catchment in the dry plains of Argentina
Jobbagy Gampel, Esteban Gabriel; Lorenzo, Santiago; Buono, Nicolás; Páez, Ricardo; Diaz, Yésica; Marchesini, Victoria; Nosetto, Marcelo Daniel (Wiley, 2021-04)Our understanding of how groundwater mediates evapotranspiration/streamflow partitioning is still fragmented and catchment studies under changing vegetation conditions can provide a useful frame for integration. We explored ... -
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 ... -
Sequía e inundación en la hiperllanura pampeana. Una mirada desde el lote al municipio
Mercau, Jorge Luis; Jobbagy Gampel, Esteban Gabriel; Viglizzo, Ernesto Francisco; Menendez, Angel N.; Di Bella, Carlos Marcelo; Bert, Federico Esteban; Portela, Silvina Isabel; Figueroa Schibber, Evelyn; Florio, Eva Laura; Giménez, Raúl; García, P.; Murray, Francisco (Universidad de Buenos Aires. Facultad de Agronomía, 2013)La variabilidad de las lluvias genera sequías e inundaciones que perjudican a campos y municipios. A nivel municipal frente al riesgo de inundación se reconoce el efecto crítico de las obras hidráulicas para defender ... -
Shallow groundwater dynamics in the Pampas: Climate, landscape and crop choice effects
Mercau, Jorge Luis; Nosetto, Marcelo Daniel; Bert, Federico Esteban; Giménez, Raúl; Jobbagy Gampel, Esteban Gabriel (2016-01-01)Depending on its depth from the soil surface, shallow groundwater can represent a valuable water resource to alleviate droughts, or a stress agent that causes waterlogging and flooding in rainfed crops. Groundwater depth ... -
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 ... -
