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

How soil microbes influence our emotions

,
When they come into contact with us, soil microbes can modulate key hormones and neurotransmitters such as dopamine, serotonin, and oxytocin, Australian researchers explain. This is how they influence our emotional states
Nei deserti l’impatto delle azioni antropiche ha interessato soprattutto il carbonio organico particolato nel terriccio e quello di origine microbica e vegetale nel sottosuolo. Foto: Circe Denyer CC0 1.0 Universal CC0 1.0 Deed

Human activity causes carbon loss in deserts

,
Some human-induced disturbances cause significant carbon loss in the soil of hyper-arid environments, a Chinese study claims. Among the most impactful activities even some practices considered “sustainable” such as seasonal harvesting and irrigation

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

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

Soil microbes tell the story of oil contamination

,
An international study has revealed how microbes can act as markers to distinguish between recent and ancient oil pollution. This overcomes the limitations of traditional chemical analysis

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

Congo peatlands are over 40,000 years old, researchers find

,
An international study reveals Congo peatlands are much older than expected. The discover provide new insights to the studies on the global carbon cycle
