A study reported in Nature analyzed floods and droughts that affected the same place twice, finding that the second occurrence caused more damage, generally speaking. The authors included scientists affiliated with the University of São Paulo.
To confirm this hypothesis, researchers in Brazil and France are conducting an experiment to find out how tree diversity influences carbon uptake and drought tolerance. The project was discussed by participants in an event held at IPT, the São Paulo State Technological Research Institute.
Brazilian researchers investigated the complexity of the world’s largest wetland biome, predicting heavier rainfall and longer dry periods, and proposing six guidelines for sustainable governance of the region.
An investigation conducted in Brazil analyzed all the microorganisms present in the feces of Nelore bulls and found biomarkers that can identify animals with a low-emission, feed-efficient phenotype.
Conclusion came from a Brazilian study that analyzed active fire occurrences between 2003 and 2020 in the nine countries with Amazon Rainforest areas. Brazil accounted on average for 73% of the fires detected in the period.
Using models based on a reserve created by the government for geological research and protection of mineral assets, Brazilian researchers estimated that opening the area up to mining would lead to the destruction of 183 km² of forest and further loss of 7,626 km² due to the direct and indirect impacts of the infrastructure required to implement and operate projects.
The process is associated with warming of the ocean subsurface resulting in a reduction of surface salinity due to the release of huge iceberg armadas from glaciers.
An article in Disaster Prevention and Management describes the course of discussions involving Brazil and the UK on how to improve flood risk governance. The project has produced an application and learning guide resulting from community participation.
In a special issue of the journal Science, some of the leading experts on the subject argue that rehabilitating degraded areas requires more complex solutions that take the biome’s specificities into account.
Conservation of CO2 stocks in the biome is highly affected by forest degradation, which could lead to at least 30% higher emissions than those produced by climate change. The warning comes from a paper by Brazilian scientists published in Science Advances.
The topic was discussed by French historian Serge Gruzinski in a lecture delivered at the FAPESP 60 Years School in Humanities, Social Sciences and Arts.
The need to adapt was emphasized by Guy Brasseur, director of the Max Planck Institute for Meteorology, Nobel Peace Laureate in 2007, and keynote speaker on the last day of the FAPESP 60 Years School.
A study using satellite imagery and machine learning techniques shows that many deforestation hotspots lie outside the 11 municipalities currently monitored by the Brazilian federal government under its Amazon Plan 2021/2022.
A study conducted at the University of São Paulo highlights the importance of riparian forests in the process.
The world’s largest tropical forest has already lost 30% of its carbon storage capacity owing to human activity. This and other topics were discussed at a webinar held to honor FAPESP’s 60th anniversary by the São Paulo State Academy of Sciences.
The finding comes from a study reported by scientists from Brazil, China, Australia and Germany in the journal Geophysical Research Letters. The group used a novel methodology focusing on low rainfall and severe drought.
Grasslands are endangered everywhere on Earth, warns a group of researchers from several countries in Nature Reviews Earth & Environment. The solution involves restoration and the pursuit of sustainable economic development alternatives.
A research group at the State University of Campinas proposes treating the solid waste produced by breweries with ultrasound before submitting it to the process of digestion by microorganisms. The strategy obtains larger amounts of methane, which can be used by the brewery itself to generate electricity and heat. The final waste can be used as crop fertilizer.
Results of studies conducted at the Research Center for Greenhouse Gas Innovation (RCGI) have fed into a bill before the Senate to set up a legal framework on carbon capture and storage as an economic activity.
In the laboratory, tadpoles of the species B. ibitiguara kept in water 3 °C warmer than the highest temperature recorded in their habitat were unable to complete metamorphosis, indicating a threat to the species from climate change.
FAPESP and 19 other research foundations will invest BRL 50 million in collaborative science projects aiming at sustainable development in the Amazon.
The workshop was a side event to the Annual Meeting of the Global Research Council. The need to dialogue with and learn from traditional communities, especially Indigenous peoples, was emphasized in the discussions.
Monitoring since 2011 shows that emission levels vary significantly from one part of the complex to another, making the standards used in environmental impact assessments and the carbon credit market unreliable.
El Niño-driven extreme drought and forest fires in 2015-16 caused the loss of 3 billion trees and emissions of 495 million metric tons of carbon dioxide in the ensuing three years, destroying more than deforestation throughout the Brazilian Amazon.
A study published in Science shows that secondary forests are more resilient than previously thought and can recover quickly, helping to mitigate the adverse effects of climate change and conserve biodiversity.
