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 ... -
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 ... -
Impacts of precipitation and temperature on crop yields in the Pampas
(2015-05)Understanding regional impacts of recent climate trends can help anticipate how further climate change will affect agricultural productivity. We here used panel models to estimate the contribution of growing season ... -
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 ... -
Land cover, plant residue and soil microbes as drivers of soil functioning in temperate agricultural lands. A microcosm study
(Elsevier, 2024-01-01)Feedbacks between plants and soil microbes are critical for ecosystem regulation and restoration. Soil microbial diversity is largely dependent on plant diversity, yet these relationships have received little attention at ... -
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 ... -
Modelling of the effects of environmental factors on rice grain discoloration incidence in Corrientes province, Argentina
(Wiley, 2023-01)Rice grain discoloration (RGD) is a disease of complex aetiology for which there are no resistant varieties. Due to the need to better define the environmental conditions that favour the disease, the aims of this work were ... -
Modelos basados en variables meteorológicas para estimar el progreso epidémico de la bacteriosis del nogal en variedades de distintos comportamientos.
(Universidade Estadual de Sao Pablo, Grupo Paulista de Fitopatologia, 2021-06-01)La bacteriosis del nogal es causada por Xanthomonas arboricola pv. juglandis. En Zavalla (Santa Fe), la actividad nogalera se centra en la producción de plantas injertadas en vivero. El presente trabajo tuvo por objetivo ... -
Modelos logísticos predictivos de la cancrosis de los cítricos en Bella Vista y su uso en el área citrícola española
(2015)La cancrosis de los cítricos, causada por la bacteria Xanthomonas citri subsp. citri, es una enfermedad cuarentenaria y endémica en el noreste argentino. Observaciones (1991-2008) de la intensidad de la cancrosis en media ... -
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, ... -
National-scale soybean mapping and area estimation in the United States using medium resolution satellite imagery and field survey
(2017)Reliable and timely information on agricultural production is essential for ensuring world food security. Freely available medium-resolution satellite data (e.g. Landsat, Sentinel) offer the possibility of improved global ... -
Natural forests loss and tree plantations: Large - scale tree cover loss differentation in a threatened dioviversity hotspot.
(IOP Publishing, 2020-12-14)Distinguishing between natural forests from exotic tree plantations is essential to get an accurate picture of the world’s state of forests. Most exotic tree plantations support lower levels of biodiversity and have less ... -
Patterns and controls of carbon dioxide and water vapor fluxes in a dry forest of central Argentina
(Elsevier, 2017-12)Covering 16% of global land surface, dry forests play a key role in the global carbon budget. The Southern Hemisphere still preserves a high proportion of its native dry forest cover, but deforestation rates have increased ... -
