A multisource information system in support of early warning systems in Brazil
Systematic documentation of disaster events is fundamental for supporting early warning systems (EWS), particularly in establishing critical thresholds and analyzing spatial patterns. Nevertheless, low-severity floods and landslides remain largely underreported because their impacts are limited and often overlooked. This study presents a comprehensive, multiscale, multisource information platform developed to strengthen early warning capacities i…
Early warning services for disaster risk reduction in Brazil
Impactos sociais dos eventos climáticos extremos
O maior desastre climático do Brasil
As inundações sem precedentes de abril a maio de 2024 no Rio Grande do Sul afetaram mais de 90% do estado, deslocando centenas de milhares de pessoas e causando 172 mortes. O fenômeno El Niño Oscilação Sul foi considerado importante para explicar a variabilidade nas chuvas observadas, consistente com pesquisas anteriores que mostram que eventos anteriores de fortes chuvas na área ocorreram durante anos de El Niño. As frentes frias que trazem chuv…
Assessing the role of compound drought and heatwave events on unprecedented 2020 wildfires in the Pantanal
The year 2020 had the most catastrophic fire season over the last two decades in the Pantanal, which led to outstanding environmental impacts. Indeed, much of the Pantanal has been affected by severe dry conditions since 2019, with evidence of the 2020’s drought being the most extreme and widespread ever recorded in the last 70 years. Although it is unquestionable that this mega-drought contributed significantly to the increase of fire risk, so f…
St Century drought-related fires counteract the decline of Amazon deforestation carbon emissions
Tropical carbon emissions are largely derived from direct forest clearing processes. Yet, emissions from drought-induced forest fires are, usually, not included in national-level carbon emission inventories. Here we examine Brazilian Amazon drought impacts on fire incidence and associated forest fire carbon emissions over the period 2003–2015. We show that despite a 76% decline in deforestation rates over the past 13 years, fire incidence increas…
Extreme seasonal droughts and floods in Amazonia
This paper reviews recent progress in the study and understanding of extreme seasonal events in the Amazon region, focusing on drought and floods. The review includes a history of droughts and floods in the past, in the present and some discussions on future extremes in the context of climate change and its impacts on the Amazon region. Several extreme hydrological events, some of them characterized as ‘once in a century’, have been reported in t…
On the associations between Hydrometeorological conditions in Amazonia and the extremes of the Southern Oscillation
Association entre les conditions hydrométéorologiques en Amazonie et les extrêmes de l’oscillation du sud L’Amazonie du nord et du centre montre une tendance vers une anomalie négative de la pluviométrie de l’été au cours des phases avancées d’événements El Niño forts comme ceux de 1982/83, 1986/87 et de 1997/98. Cependant on observe aussi une tendance vers une anomalie positive de la pluviométrie, certaines années El Niño comme 1972/73. Une inve…
