Sea level rises threatening wetland carbon

,
L'ascesa del livello del mare mette a rischio la capacità di stoccaggio del carbonio alterando la presenza dei microbi e la vegetazione, osservano i ricercatori americani

Heat and drought drive carbon loss in tropical forests

,
A warmer and drier climate will impact the carbon balance of forests in the future, says a US study. The phenomenon will accelerate the loss of the oldest element and reduce the supply of the new one

Soil bacteria survive by cooperating with each other

,
With gene sequencing, researchers at Ohio State University have shown how bacteria cooperate to thrive in environments characterised by different pH levels
In California the rate of erosion after post-fire floods increased between 3.5 and 4.6 times. Photo: Tomwsulcer CC0 1.0 Universal CC0 1.0 DeedTomwsulcer CC0 1.0 Universal CC0 1.0 Deed

In California, fires and subsequent floods accelerate erosion

,
According to a study by the US Geological Survey, erosion on California coasts is closely linked to extreme weather events enhanced by progressive climate change

The price of climate change is getting higher for Africa

,
Climate change impacts Africa's agriculture and food security. High costs and insufficient investment remain the biggest problems, latest report by the UN Development Programme has found
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

Invasive plants threaten Arctic biodiversity

,
Biodiversity at risk: Norwegian research provides a picture of the growing presence of invasive plants on Svalbard. "We need to prevent the phenomenon," scientists explain

“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"

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
