USA, erosion runs 1000 times faster than normal

,
The discovery is contained in a thesis of master at Umass Amherst University. To calculate the rate of erosion, a team of researchers quantified the presence of a rare element - Beryllium 10 - in cultivated prairies in 5 US states, comparing them with virgin soils

Four U.S. universities are launching a massive soil analysis project. The initiative aims to counter land degradation which is estimated to cost $67 bn a year in America
In one year, the Planet's soils absorbed 109 million tons of synthetic nitrogen fertilizers. Photo: P177 Attribution 2.0 Generic (CC BY 2.0)P177 Attribution 2.0 Generic (CC BY 2.0)

A new project will monitor global nitrogen emissions from fertilizers

The Global Research Alliance initiative aims to increase the availability of data on the impact of fertilizers on the Planet. And to better assess the effectiveness of mitigation practices
From 2009 to 2020, sales of pesticides in Germany decreased only slightly, from about 30,000 to 28,000 tons per year. Photo: Jakob Huber/Campact Attribution-NonCommercial 2.0 Generic (CC BY-NC 2.0)Jakob Huber/Campact Attribution-NonCommercial 2.0 Generic (CC BY-NC 2.0)

Germany, the reduction in the use of pesticides is still too slow

,
The use of pesticides in Germany decreased by less than 10 percent between 2009 and 2020. The figure raises many concerns about the spread of integrated pest management, a technique designed to reduce the use of the most dangerous chemicals
By 2022, the Brazilian Amazon suffered its worst deforestation in 15 years, losing the equivalent of nearly 3,000 soccer fields a day.

Record monthly deforestation in the Amazon is alarming for Lula

,
In February, the Amazon lost more than 300 km2 of forest. Brazil's new government promised a turnaround after the woes suffered under President Bolsonaro. Between 2004 and 2012 Brazil recorded its best results in land protection
For years, the amount of sargasso algae present in Caribbean and US waters and beaches has been increasing. And it's no longer relegated to the months when the water is warmer.

Florida, behind the invasion of seaweed two actions of man on land

,
The coasts of the US state and other Caribbean states are invaded by abnormal quantities of sargasso: it is estimated that the seaweed are almost 9,000 kilometers long and weigh 20,000 tons. However, the abuse of agricultural fertilizers and deforestation are at the basis of the phenomenon. A confirmation of the bond that unites the health of the soils with that of the oceans
In poor countries, phosphorus loss could impact yields of 70 percent of rice fields. Photo: Arian Zwegers Attribution 2.0 Generic (CC BY 2.0)Arian Zwegers Attribution 2.0 Generic (CC BY 2.0)

CO2 emissions reduce soil phosphorus and put rice crops at risk

,
According to an international study, soil phosphorus is reduced due to prolonged exposure to high levels of CO2 in the atmosphere. The resulting decline in paddy field yields is a threat to food security

Green deal, new EU targets approved for carbon sequestration

,
The European Parliament approved the revision of the regulation relating to the LULUCF (Land use and forestry sector). By 2030, the sector will have to guarantee the absorption of 310 Mt of CO2, 15% more than today. Expected binding obligations for all EU Member States
