France is the latest victim of global desertification

,
Late last year, France was added for the first time to the UN list of countries declared affected by land degradation and desertification. A phenomenon that impacts more than 3 billion people worldwide

Climate change increases mortality caused by extreme temperatures

,
Study tracks future climate mortality in Europe: fewer deaths from cold weather but many more casualties from extreme heat. The Mediterranean will pay the highest price
Worldwide, land degradation is growing by 1 million square kilometers per year, explains the Potsdam Institute for Climate Impact Research. Drylands include three-quarters of Africa. Photo.

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"

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
