The impact of wildfires on understorey and biodiversity rises in Australia

,
In areas affected by wildfires, which are increasingly severe and frequent in Australia as in the rest of the planet, there is a decrease in plant diversity
In China, the addition of biochar to agricultural soils has generally increased the organic carbon content of soil aggregates.

Here is how biochar promotes the sequestration of organic carbon

,
Biochar promotes the formation of soil aggregates and, with them, carbon sequestration, a research explains. In some Chinese farmland, the presence of the substance has increased by 60 per cent
Water that does not evaporate first passes through the canopies and carries nutrients to the soil through leaves and branches or along the stems. Photo: Stuart Rankin CC BY-NC 2.0 DEED Attribution-NonCommercial 2.0 GenericStuart Rankin CC BY-NC 2.0 DEED Attribution-NonCommercial 2.0 Generic

This is how canopies affect the distribution of soil nutrients

,
Chinese research analyzed nutrient precipitation dynamics by identifying and quantifying soil enrichment mechanisms in relation to climate and vegetation
The researchers' hope is that by predicting drought in advance, farmers and ranchers can better plan for water management. Photo: jackoscage CC BY 2.0 DEED Attribution 2.0 Genericjackoscage CC BY 2.0 DEED Attribution 2.0 Generic

NASA follows the light and anticipates flash droughts

,
Space Agency researchers have found a correlation between flash drought and the intensity of induced fluorescence. A phenomenon related to photosynthesis and observable from space

Soil, wildfires and recovery: how much do we know?

,
A U.S. study reviews current knowledge about wildfires and the resilience of ecosystems. Some factors can promote regeneration. Others end up impeding it

Legacy of soil sealing studied in Strasbourg

,
The PerméaSol project will study the ecological trajectory of "liberated" urban soil over the next 3 years. Thus assessing the long-term effects of sealing
According to the United Nations, degradation affects up to 50 percent of the Planet's rangelands. Photo: ILRI/Stevie Mann CC BY 2.0 DEED Attribution 2.0 GenericILRI/Stevie Mann CC BY 2.0 DEED Attribution 2.0 Generic

“Half of the Planet’s rangelands are degraded,” UN says

,
A snapshot from the latest UNCCD Report: degradation affects up to 50 percent of rangelands, twice as much as previous estimates. Central Asia and North Africa are the hardest hit areas
In the Tibetan Plateau, the benefits of vegetation enhancement for erosion control will be undermined by climate change. Photo: McKay Savage CC BY 2.0 DEED Attribution 2.0 GenericMcKay Savage CC BY 2.0 DEED Attribution 2.0 Generic

Climate mitigation is the first barrier against erosion in Tibet

,
Climate change will be decisive in increasing erosion in the Tibetan Plateau, a Chinese study finds. So curbing rising temperatures becomes decisive

How organic carbon accumulates in acidified forest soils

,
A study by the Chinese Academy of Sciences reveals how forest soil acidification promotes both mineral protection and plant-derived carbon accumulation

Mountain meadows are threatened by climate change

,
Rising temperatures drives the loss of humus in mountain meadows and, with it, the release of CO2 into the atmosphere. This is reported in a study by the Technical University of Munich
