US researchers test a sensor to assess nutrient loss

,
A research project at the University of Missouri describes the potential of a new instrument to detect the presence of phosphorous- and nitrogen-based nutrients in the soil. An innovation that would pave the way for a more sustainable use of fertilisers
By applying the most suitable forest restoration system in each location, 31.4 billion tonnes of CO2 could be sequestered globally. Photo: Neb Attribution-ShareAlike 4.0 International CC BY-SA 4.0 DeedPhoto: Neb Attribution-ShareAlike 4.0 International CC BY-SA 4.0 Deed

Mixed forest regeneration optimises carbon sequestration

,
An American study quantifies the efficiency of different forest regeneration methods. By applying the most cost-effective system for each location, around 10 billion tonnes more CO2 can be sequestered at the same cost

Are China’s solar parks a viable tool against desertification?

,
In China, the expansion of photovoltaic installations is reportedly helping to combat desertification. An interesting hypothesis given the scale of the problem. But the issue is still controversial

“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"
The rate of permafrost erosion could even triple by the end of the century, thus impacting the climate. Photo: Brandt Meixell, USGS CC0 1.0 Universal CC0 1.0 DeedBrandt Meixell, USGS CC0 1.0 Universal CC0 1.0 Deed

Permafrost erosion reduces carbon sequestration in the oceans

,
A German study shows how permafrost erosion on the coast of the Arctic Ocean leads to an almost 15 per cent decrease in the seawater's ability to store CO2

Ecoacoustics: how soil sounds measure biodiversity

,
Australian research has highlighted the correlation between the complexity of noise produced by invertebrate communities and the level of soil biodiversity

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

Indigenous communities in the forest pay the price of drought

,
Drought leads to a prolonged lowering of river levels in the Amazon causing local communities to become isolated, a study by the Autonomous University of Barcelona has found. This problem affects more than 50% of indigenous villages
