Freeing up soil is possible. Experts share regeneration experiences trough de-sealing

,
Soil sealing is a global problem affecting large urban centers. But new tools, explains the FAO, can now guide sustainable planning

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

Greener but less wet: a Chinese study reveals the global soil paradox

,
Research: in forty years, two-thirds of vegetated areas have become greener, but half of those also experienced considerable soil drying. Crucial factor: increased evapotranspiration
Il taglio del 20% nell’impiego dei fertilizzanti chimici raccomandato dall’Unione Europea non sarebbe sufficiente per raggiungere l’obiettivo fissato dal Green Deal di dimezzare le perdite di nutrienti entro il 2030. Foto: Vladimir Srajber pexels free to use

Cutting fertilizer use will not be enough to meet EU nitrogen targets

, ,
A study by the UFZ in Leipzig reveals that a 20% reduction in the use of nitrogen fertilizers will result in a relatively modest decrease in nutrient losses to soil. Regional agricultural systems are a decisive factor
Wetlands sequestered an average of one billion tons of carbon per year in the first two decades of the 21st century. Photo: Svetlana Makarova Attribution-ShareAlike 2.0 Generic CC BY-SA 2.0 Deed Photo: Svetlana Makarova Attribution-ShareAlike 2.0 Generic CC BY-SA 2.0 Deed

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

Hyperspectral images reveal the health status of vegetation in Antarctica

,
An Australian study reveals the importance of aerial survey based on a more advanced technique to assess the health and density of vegetation in an area with limited spectral range such as Antarctica. The highest accuracy exceeds 99%
Fires are the main cause of prolonged heat stress in degraded tropical forests. Photo: Bruno Kelly/Amazônia Real/11/08/2020 Attribution 2.0 Generic CC BY 2.0 DeedBruno Kelly/Amazônia Real/11/08/2020 Attribution 2.0 Generic CC BY 2.0 Deed

In the Amazon region post-fire stress can last in forests for decades

,
NASA research shows that forests in the region affected by fires remain warmer than normal for at least 30 years. This has obvious consequences for their carbon storage and climate mitigation capacity
The results of the study open up new prospects in the fight against the most dangerous bacteria for plants, such as Ralstonia solanacearum, which affects over 200 plant species, including key crops such as tomatoes and potatoes.

AI helps plants track down mutant bacteria

,
A group of Californian researchers has used artificial intelligence to design improved versions of a receptor, expanding its ability to recognize threatening bacteria. This has updated the plants' defense system.
