“Desertification is the greatest environmental challenge of our time”

,
The phenomenon involves 168 countries, over 3 billion people and 10% of the world's soils. Alain-Richard Donwahi, President of the UNCCD (UN Convention against desertification) explains the importance of the "forgotten COP"

Bacteria help predict soil acidity in grasslands

,
A new Chinese model based on bacterial analysis allows to estimate changes in grasslands. By 2100, soil acidity will decrease especially in North-East Asia, Africa and Oceania

Amazon, land protection initiatives have reduced deforestation by 83%

,
In the first decade of the century, the Amazon experienced a sharp decline in deforestation, explains an international study. But the economic benefits for the indigenous people have been limited. This is why new initiatives are needed
Due to their carbon sequestration potential, forests are an essential resource in climate change mitigation. Photo: USDA Nicholas A Toneli Creative Commons; Attribution 2.0 Generic (CC BY 2.0)USDA Nicholas A Toneli Creative Commons; Attribution 2.0 Generic (CC BY 2.0)

Forests still offset half of global fossil emissions

,
The world's forests, an American study notes, absorb between 3.5 and 4 billion tonnes of carbon each year. Equivalent to "nearly half of the carbon dioxide emissions from burning fossil fuels between 1990 and 2019."
