A land cover map of Latin America and the Caribbean in the framework of the SERENA project
(Elsevier, 2013-05-15)Land cover maps at different resolutions and mapping extents contribute to modeling and support decision making processes. Because land cover affects and is affected by climate change, it is listed among the 13 terrestrial ... -
A MODIS based tool to assess inundation patterns: an example for the Paraná Delta River
(Gerencia de Comunicación e Imagen Institucional, DG-SICyP, INTA, 2020-04)Wetlands are one of the most productive yet altered ecosystems due to human activities across the world. They rely largely on their water flow to provide several ecosystem functions. Then, to develop a land use plan that ... -
A multi-resolution approach to national-scale cultivated area estimation of soybean
(2017-06)Satellite remote sensing data can provide timely, accurate, and objective information on cultivated area by crop type and, in turn, facilitate accurate estimates of crop production. Here, we present a generic multi-resolution ... -
An integrative index of Ecosystem Services provision based on remotely sensed data
(Elsevier, 2016-12)We present an approach to generate estimates and to map Ecosystem Services (ES) related to C and water dynamics (Soil Carbon sequestration, evapotranspiration and groundwater recharge) and biodiversity (Avian Richness) ... -
Caracterización funcional de la estepa magallánica y su transición a matorral de Mata Negra (Patagonia austral) a partir de imágenes de resolución espacial intermedia
(Facultad de Agronomía, Universidad de Buenos Aires, 2011)La PPNA es indicadora de la biomasa disponible y se relaciona con la capacidad de carga de los sistemas pastoriles extensivos. Es posible estimarla a partir de índices de vegetación obtenidos de sensores remotos. El objetivo ... -
Caracterización regional de la estructura y de la productividad de la vegetación de la Puna mediante el uso de imágenes MODIS
(Asociación Argentina de Ecología, 2012-04)La Puna es una región semiárida ubicada por encima de los 3300 m.s.n.m. en el noroeste argentino. Si bien existen descripciones florísticas parciales de la vegetación en el área, no existen trabajos que describan su fisonomía ... -
Changes in vegetation seasonality and livestock stocking rate in La Pampa Province (Argentina) = Cambios en la estacionalidad de la vegetación y la carga animal en la provincia de La Pampa (Argentina)
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019)Crop production is traversing expansion and intensification processes all over the planet and in consequence the large scale cattle production is being displaced to marginal lands with lower stocking capacity. The objective ... -
Climatic determinants of photosynthetic activity in humid subtropical forests under different forestry activities
(Elsevier, 2022)Forests are key ecosystems providing a variety of contributions to societies that are based on the ecological processes occurring in them. Understanding the relationship between ecological processes and the climate system ... -
Desertification and ecosystem services supply : the case of the Arid Chaco of South America
(Elsevier, 2018-12)New integrated perspectives are increasingly needed to bridge the gap between biophysical and ecosystem services' based assessments of desertification. For a vast area of the dry Chaco region we sought to: (1) assess the ... -
Dinámica de la fenología de la vegetación a partir de series temporales de NDVI de largo plazo en la provincia de La Pampa
(Asociación Argentina de Ecología, 2013-08)La cubierta vegetal es un indicador natural de la salud ambiental y tendencia climática, y la actividad fotosintética permite detectar esas variaciones. No obstante, su evaluación a escala de región es una tarea complicada ... -
Dónde, cuándo y cómo ocurren grandes incendios en la provincia de La Pampa, Argentina. Una caracterización basada en sensores remotos.
(Asociación Argentina de Ecología, 2023-02-12)Los incendios son fenómenos catastróficos, devastadores, peligrosos y costosos para una región. A pesar de su relevancia, se conoce poco sobre su dinámica espacial y temporal en la provincia de La Pampa. El objetivo general ... -
Estudio de la relación entre el NDVI-MODIS y el rendimiento de trigo en el Noreste de Buenos Aires
(Facultad de Agronomía y Veterinaria, Universidad Nacional de Río Cuarto, 2010)En países cuya economía depende en gran medida de la producción de cultivos, la estimación de las cosechas agrícolas es un requisito elemental para que puedan generarse medidas que favorezcan a todo el proceso productivo ... -
Evaluación del desempeño de productos satelitales para estimar evaporación en la región pampeana (Argentina)
(Sociedad Argentina de Informática, 2019-09-16)La evapotranspiración es una variable de importancia, después de la precipitación, por sus efectos en los ciclos hidrológicos. Su cuantificación es necesaria por su dependencia, en el área agrícola, del tipo de uso y humedad ... -
Functional syndromes as indicators of ecosystem change in temperate grasslands
(Elsevier, 2018-09-24)The lack of an organizing conceptual framework to address ecosystem changes reduces our capacity to distinguish biophysical from direct human impacts on grassland dynamics. This is particularly important for subhumid ... -
Influence of fuel conditions on the occurrence, propagation and duration of wildland fires: A regional approach
(2015-09)Wildfires affect Earth's surface every year. Fuels conditions influence fire occurrence and behavior; therefore, their characterization is important for fire risk studies. We analyzed vegetation conditions influencing fires ... -
Phases or regimes? Revisiting NDVI trends as proxies for land degradation
(Wiley, 2018-03)One of the main challenges in land degradation assessment is that a rigorous and systematic approach to addressing its complex dynamics is still missing. The development and application of operative tools at regional and ... -
Selecting control sites for post-fire ecological studies using biological criteria and MODIS time series data
(Association for Fire Ecology, 2017)Wildland fires play a key role in the functioning and structure of vegetation. The availability of sensors aboard satellites, such as Moderate Resolution Imaging Spectroradiometer (MODIS), makes possible the construction ... -
Towards a set of agrosystem-specific cropland mapping methods to address the global cropland diversity
(Informa UK Limited, 2016)Accurate cropland information is of paramount importance for crop monitoring. This study compares five existing cropland mapping methodologies over five contrasting Joint Experiment for Crop Assessment and Monitoring (JECAM) ... -
Trends in ANPP response to temperature in wetland meadows across a subcontinental gradient in Patagonia
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-06-17)Due to ongoing global warming, seasonal patterns of aboveground net primary production (ANPP) may be altered by temperature trends. Of particular interest is the seasonal association between ANPP and temperature at the ... -
