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 ... -
Multi-Temporal analysis of remotely sensed information using wavelets
(Scientific Research Publishing, 2012)Land cover changes (LCC) are an important component of Global Change. LCC can be described not only by its occur-rence, but also by the land cover replacement, causal agent and change duration or recuperation. Nowadays, ... -
Informe trimestral de la red de monitoreo hidrológico de la cuenca del río Arrecifes (Abril-junio 2018) : sistema de monitoreo hídrico rural-urbano
(AER Arrecifes, 2018-07)En este informe se presentan los resultados obtenidos para el segundo trimestre de 2018 de la red de monitoreo hidrológico de la cuenca del río Arrecifes. Esta red se encuentra operativa desde 2009 y actualmente cuenta con ... -
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) ... -
Impact of land use during winter on the balance of greenhouse gases
(Wiley, 2018)The increase in atmospheric greenhouse gases (GHGs) can be mitigated by capturing CO2 from the atmosphere and/or by reducing their emissions. Replacing winter intercrop fallow by cover crops (CCs) can sequester carbon and ... -
Has climate change opened new opportunities for wheat cropping in Argentina?
(Springer, 2013-03)As a result of climate change, and in particular rainfall changes, agricultural production is likely to change across the globe. Until now most research has focused on areas which will become unsustainable for agricultural ... -
Relationship between biophysical parameters and synthetic indices derived from hyperspectral field data in a coastal marsh from Buenos Aires Province, Argentina
(Springer, 2016-02)Remote sensing tools allow the environmental evaluation of coastal wetlands at a landscape scale, but a deeper understanding is needed of the interactions between biophysical parameters and the electromagnetic signal. The ... -
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 ... -
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 ... -
The agro-ecological suitability of Atriplex nummularia and A. halimus for biomass production in Argentine saline drylands
(Springer, 2014-09)The choice of the best species to cultivate in semi-arid and arid climates is of fundamental importance, and is determined by many factors, including temperature and rainfall, soil type, water availability for irrigation ... -
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 ... -
Long-lasting floods buffer the thermal regime of the Pampas
(Springer, 2018-01)The presence of large water masses influences the thermal regime of nearby land shaping the local climate of coastal areas by the ocean or large continental lakes. Large surface water bodies have an ephemeral nature in the ... -
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 ... -
CO2 and N2O flux balance on soybean fields during growth and fallow periods in the Argentine Pampas—A study case
(Elsevier, 2017-06)The estimation of the GHG balance of agroecosystems is essential to evaluate the impact of agriculture on the composition of the atmosphere. Cultivated soils may act as a sink or a source of CO2 and usually emit N2O. The ... -
Development of agroclimatic zoning model to delimit the potential growing areas for macaw palm (Acrocomia aculeata)
(Springer, 2017-08)The growing biodiesel production requires the use of new technologies and alternative feedstocks to maintain the growing demand of this biofuel. The macaw (Acrocomia aculeata) is a palm native to Argentina whose fruits ... -
Ammonia emissions from the agriculture sector in Argentina; 2000–2012
(Elsevier, 2018-04)Agriculture is one of the key economic sectors in Argentina and, in the last decades, the increase in prices and competitiveness of some grains has imposed important changes. In this process, crop cultivation occupied ... -
Propuesta de sistematización agrohidrológica en cuencas de llanura con énfasis predial y consorciado = Proposal for agro-hydrological systematization in basins plaines with emphasis predial and consortial
(Universidad Nacional del Litoral. Facultad de Ciencias Agrarias, 2017)Existe escasa tecnología para el manejo de aguas superfi ciales en áreas de planicie extrema e inundable, aumentada por la controversia de opinión en cuanto al modo de encarar la solución de los excesos y défi cit hídricos. ... -
Validación de sistemas de pronóstico del impacto de la fusariosis de la espiga en cultivares de trigo
(2016-07)En Argentina, el principal agente causal de la enfermedad conocida como fusariosis de la espiga de trigo (FET) es el hongo Fusarium graminearum (Schwabe) (teleomorfo Gibberella zeae (Schwein)). La FET es una enfermedad ... -
Remote sensing and cropping practices: a review
(2018)For agronomic, environmental, and economic reasons, the need for spatialized information about agricultural practices is expected to rapidly increase. In this context, we reviewed the literature on remote sensing for mapping ... -
