Tracking soybean to stop deforestation with chemistry and AI

, ,
An innovative method combines chemical fingerprinting and machine learning to pinpoint the origin of soybeans with unprecedented accuracy. A practical tool to support the enforcement of stricter traceability rules

Beyond the Amazon: a forgotten carbon reserve in Brazil’s wetlands

,
In the Brazilian savanna, wetlands store enormous amounts of carbon, but they are threatened by climate change and agricultural expansion. Moreover, conservation policies, which focus almost exclusively on forests, tend to ignore them

A new index measures soil health in mangrove forests

, ,
Brazilian researchers have developed an indicator to measure the ability of mangroves to provide ecosystem services, ranging from biodiversity conservation to carbon sequestration. The greater the soil degradation, the lower the score
The study has important implications for climate change, as tropical forests are essential carbon sinks for the planet.

Nitrogen doubles the regeneration speed of tropical forests

,
When provided with adequate nitrogen tropical forests can recover from deforestation twice as fast as they would under normal circumstances, a research led by the University of Leeds has found
The construction of new roads is a particularly significant sign of deforestation. However, many of them are difficult to identify.

A map of future roads helps fight deforestation

,
A team of Australian researchers managed to develop a deforestation risk index based on the probability that an area may be affected by new road construction

Meat and soybean (plus coffee) are driving deforestation in the Amazon

,
The latest WWF report identifies the main factors behind the ongoing phenomenon in the Amazon. Meat and soy top the list in terms of impact, ahead of cocoa, palm oil, and coffee

Carbon balance in Amazon rainforest shows 370 million tons deficit in a decade

,
Between 2010 and 2020, carbon losses increased due to deforestation and other underestimated phenomena such as fires and fragmentation, according to new study. Emission intensity is higher in protected areas

Drought, climate change, and scientific diplomacy: a collective response from Latin America

,
Science cannot act alone to combat the climate crisis, and without it, no transformation is possible. Some experiences developed by South American countries highlight the importance of acting jointly

A Chinese study has quantified 20 years of carbon sequestration in wetlands

,
Research by the Chinese Academy of Sciences reveals that wetlands sequestered an average of one billion tons of carbon per year in the first two decades of the century. Seventy percent of this capture takes place in tropical areas
