Extreme heat waves are becoming longer and more frequent

,
A study on abnormal heat phenomena, involving researchers from the United States and Chile, reveals an acceleration of the trend on a global scale. Tropical regions are the most affected

The trees that weren’t there: a new map reveals previously unseen plants in the tropics

, ,
New research reconsiders the presence of trees in tropical regions. Until now models excluded one in six plants. Thus ignoring the related ecological benefits

Drought, the Mediterranean in the hotspot in the world is small

,
Un nuovo rapporto dell'UNCCD ha individuato gli impatti, ambientali, sociali ed economici della siccità nelle zone più colpite nel biennio 2023-2024. Tra loro, Spagna, Marocco e Turchia. "Una catastrofe globale che si estende su milioni di km quadrati e colpisce milioni di persone"

Drought is once again a major threat to European agriculture

,
Agricultural drought is affecting northwestern Europe, the Baltic and some eastern and southern regions of the Continent. In contrast, following heavy rains higher yields are expected in Italy, Greece and the Iberian Peninsula

A public database collects information on soil fungi

,
After years of study, a group of U.S. researchers has mapped the spore traits of 344 species of arbuscular mycorrhizal fungi. Gaining relevant information to assess their distribution and resilience to stresses
Drones can photograph the health of crops providing crucial information to farmers. Photo: Nikola Tomašić Pexels free to usePhoto: Nikola Tomašić Pexels free to use

Drones are the new allies of hemp farmers in the US

, ,
Processing of images captured by drones, a study from the University of Florida states, makes it possible to assess the health and growth status of plants by providing guidance on the optimal fertilizer dose

Europe’s soil carbon sink declines (but the trend can be reversed)

,
According to the EU Environment Agency, from land use, land use change and forestry, Europe saves almost 200 million tonnes of carbon each year. Compared to 330 recorded on average between 1991 and 2013
Peat soils in Ireland are more widespread than previously thought as they cover 30% of the land area compared with previously estimated 24%. Photo: SoilScience.info Attribution 2.0 Generic CC BY 2.0 DeedSoilScience.info Attribution 2.0 Generic CC BY 2.0 Deed

Ireland has mapped its peat soils (through AI and gamma rays)

, ,
By combining AI machine learning with radiometric data, researchers at the University of Galway managed to identify not previously detected peat soils
Grasslands are home to a wide variety of plant species and provide numerous ecosystem services, such as carbon sequestration, support for pollinators and grazing for livestock. But they are also some of thh most threatened ecosystems due to human activities, including land use change and intensive agricultural practices.

Study reveals how much nitrogen grasslands can tolerate

, ,
According to researchers, applying more than 80 kg of nitrogen per hectare in a year would make grasslands “functionally poor, highly unstable and vulnerable to extreme weather events”

How AI will ensure better prediction of erosion

,
L'Università dell’Illinois, ha testato un sistema di apprendimento automatico che combina diversi modelli predittivi dell'erosione. Con risultati migliori rispetto a quelli ottenuti dai singoli algoritmi
