Assessment of the soil water content in the Pampas region using SWAT
(2016-02)La región Pampeana ha experimentado recientemente una expansión de la agricultura hacia ambientes más frágiles, que se ha asociado con un aumento en la frecuencia de las sequías que afectan a toda la región. En el presente ... -
Attribution of carbon dioxide fluxes to crop types in a heterogeneous agricultural landscape of Argentina
(Springer, 2014-10)The increasing proportion of agricultural lands worldwide makes it necessary to intensify the research concerning the carbon exchange at agricultural sites. In order to determine the Net Ecosystem Exchange (NEE) in an ... -
Automatización de reportes agrometeorológicos
(Asociación Argentina de Agrometeorología, 2020-11-23)Disponer de información agrometeorológica es de suma importancia en el ámbito agropecuario, especialmente al momento de tomar decisiones. De esta manera, es fundamental contar con información desde distintas fuentes para ... -
Barriers and solutions to conducting large international, interdisciplinary research projects
(Springer, 2017-12)Global environmental problems such as climate change are not bounded by national borders or scientific disciplines, and therefore require international, interdisciplinary teamwork to develop understandings of their causes ... -
Building a Data Set over 12 Globally Distributed Sites to Support the Development of Agriculture Monitoring Applications with Sentinel-2
(MDPI, 2015-12)Developing better agricultural monitoring capabilities based on Earth Observation data is critical for strengthening food production information and market transparency. The Sentinel-2 mission has the optimal capacity for ... -
Calidad altimétrica de un modelo digital de elevación generado con imágenes banda L de SAOCOM
(Instituto Nacional del Agua (INA), 2023-08-28)Los modelos digitales de elevación (MDEs) constituyen un insumo clave para la caracterización y modelización hidrológica de una cuenca. Es decir, a partir de esta información se puede interpretar la dinámica del escurrimiento, ... -
Cambio climático y producción ganadera en Argentina
(Instituto de Clima y Agua, INTA, 2017)El cambio climático y los sistemas de producción ganadera se relacionan por medio de dos vías: 1. El impacto que el cambio climático tiene en los sistemas. 2. Las emisiones de gases con efecto invernadero (GEI), generadas ... -
Caracterización de rotaciones de cultivos y su impacto en el rendimiento y funcionamiento de sistemas agrícolas
(Facultad de Agronomía, Universidad de Buenos Aires, 2023-04-27)El análisis de las rotaciones de cultivos a escala regional requiere información histórica a nivel de lote que considere las diferentes condiciones presentes en el área. Esta información ha sido de escasa y dispersa en ... -
Carbon and water vapor balance in a subtropical pine plantation
(2016-10)Afforestation has been proposed as an effective tool for protecting primary and/or secondary forests and for mitigating atmospheric CO2. However, the dynamics of primary productivity differs between plantations and natural ... -
Carbon dioxide fluxes on a soybean field in Argentina: influence of crop growth stages
(Bentham Open, 2010)CO2 fluxes were measured in a soybean field in the Province of Buenos Aires, Argentina, with an eddy covariance system consisting of a CO2/H2O infrared gas analyzer and a sonic anemometer. The measurements were carried out ... -
