The top-line findings of a massive analysis of the growth rate of more than 20,000 tropical trees in over 30 countries may at first seem reassuring: that droughts over the past century have had a minimal effect on their growth.

Study shows that carbon and nitrogen losses from the soil persist for nearly a decade after burning, and conversion to agriculture causes even more severe impacts. Frequent forest fires and agricultural expansion are degrading soil health in the southern Brazilian Amazon. This results in lasting damage to carbon (C) and nitrogen (N) stocks, as well as to the overall functionality of ecosystem soils. These findings are presented in a study conducted by researchers from Brazil, the United [...]

One of the pillars of the Brazilian economy and one of the sectors responsible for the highest greenhouse gas emissions, beef production in Brazil, as it is currently practiced, emits more than twice the limit needed to meet international environmental targets.

Giving a second life to construction materials after demolition, engineers at the University of São Paulo and Princeton have developed an approach for recycling cement waste into a sustainable, low-carbon alternative that is comparable in performance to the industry standard.

Agricultural fertilizers are critical for feeding the world's population, restoring soil fertility and sustaining crops.

Extreme temperatures and humidity levels (excessive rain or drought) projected for the Amazon in the context of climate change may increase the volume of methane-producing microorganisms in flooded areas and reduce potential uptake of this greenhouse gas in upland forests by 70%, with global impacts, according to a study conducted by researchers at the University of São Paulo (USP) in Brazil. An article reporting their findings is published in the journal Environmental [...]

Seasonal variations with alternating dry and rainy seasons and fluctuating levels of nutrients are factors that significantly influence greenhouse gas emissions from soda lakes in the Pantanal, considered less common than emissions from freshwater lakes.

In Brazil, climate and other human-made environmental changes threaten decades-long efforts to fight a widespread and debilitating parasitic disease. In Brazil, climate and other human-made environmental changes threaten decades-long efforts to fight a widespread and debilitating parasitic disease. Now, a partnership between researchers from Stanford and Brazil is helping to proactively predict these impacts.  Schistosomiasis, spread by freshwater snails, affects more than 200 [...]

Researchers at the University of Jyväskylä have found that the key to a quick and cost-effective mapping of biodiversity has been right in front of our eyes all along, but at the same time invisible, i.e. in the air that surrounds us.
