ABSTRACT.- Under the EU Renewable Energy Directive (2009/28/EC), estimating biofuel GHG emissions is essential to gauge emissions reductions compared to fossil fuels. Within this framework, the carbon footprint (CF) was calculated for four bioethanol cropping systems:a maize-wheat-sorghum rotation without the harvest of crop residues (MWS), a maize-wheat-sorghum rotation with harvested crop residues (MWS-R), switchgrass (Sw), and continuous sweet sorghum (Ss). The estimation followed a life-cycle analysis strategy. The CF varied between 0.04 and 3.68 kg CO2-eq l -1 ethanol.

ABSTRACT.- Approaches to rapidly collecting global biodiversity data are increasingly important, but biodiversity blind spots persist. We organized a three-day Datathon event to improve the openness of local biodiversity data and facilitate data reuse by local researchers. The first Datathon, organized among microbial ecologists in Uruguay and Argentina assembled the largest microbiome dataset in the region to date and formed collaborative consortia for microbiome data synthesis. © 2024 The Author(s)

INIA y Conaprole trabajan juntos en el análisis de la huella de carbono de los sistemas de producción lecheros y en la elaboración de una metodología para desarrollar estrategias para su reducción.

Los días 6 y 7 de marzo, se llevó a cabo en INIA La Estanzuela un simposio de riego, enfocado en las tecnologías de sensoramiento remoto como herramientas para un manejo eficiente del riego a nivel de cuencas y predial. El evento convocó a un centenar de profesionales, tomadores de decisión institucionales, estudiantes y productores para conocer avances en sistemas de gestión de agua para riego y experiencias de otros países en esta materia.

ABSTRACT.- Wheat blast, caused by the Pyricularia oryzae Triticum lineage (PoT), first emerged in Brazil and quickly spread to neighboring countries. Its recent appearance in Bangladesh and Zambia highlights a need to understand the disease's population biology and epidemiology so as to mitigate pandemic outbreaks. Current knowledge is mostly based on characterizations of Brazilian wheat blast isolates and comparison with isolates from non-wheat, endemic grasses.
