Ultrasound device measures the impact of drought on plants

,
A new device developed by a team of Lithuanian and Spanish researchers allows detection of the alteration produced by drought on certain key parameters of the plant's physiological state

Desertification halves soil functionality in Brazil

,
The calculation is contained in research conducted by two universities in the country, which analysed degraded areas in the north-east of Brazil. A confirmation of the impact of desertification on the soil's ability to sequester carbon

Despite inequalities, women are forefront against drought

,
The UNCCD-FAO Report: "Women are most vulnerable to drought but are also at the forefront in developing solutions to the problem." They produce up to 80 per cent of the food in developing countries, but represent less than 20 per cent of landowners

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"
In some Asian countries, the frequency of flash drought events has increased from 20% to 80%.

Flash drought is becoming increasingly frequent in Asia

,
In some Asian countries, says research, the frequency of sudden drought events has increased from 20 to 80 per cent in just two decades. But the phenomenon is now global
Globally, scientists explained, wetlands are rich in biodiversity and provide various services including water supply for agricultural use and carbon storage.

Here is how the climate will affect the wetlands in North America

,
Wetlands, a study from the US explains, will experience substantial drying during the summer. Impacting habitat and biodiversity from Florida to Mississippi to southeastern Canada

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
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
