In the Amazon region post-fire stress can last in forests for decades

,
NASA research shows that forests in the region affected by fires remain warmer than normal for at least 30 years. This has obvious consequences for their carbon storage and climate mitigation capacity
The results of the study open up new prospects in the fight against the most dangerous bacteria for plants, such as Ralstonia solanacearum, which affects over 200 plant species, including key crops such as tomatoes and potatoes.

AI helps plants track down mutant bacteria

,
A group of Californian researchers has used artificial intelligence to design improved versions of a receptor, expanding its ability to recognize threatening bacteria. This has updated the plants' defense system.

Root bacteria help reduce the environmental impact of rice cultivation

,
A Japanese study has identified some bacteria in rice roots that are responsible for nitrogen fixation and can spread in soil without fertilizers or pesticides. This helps the plant adapt and grow

Plant roots could store more carbon than previously expected at greater depths

,
An American study reveals the existence of a second layer of roots developed by several plant species—often overlooked—that enables additional carbon sequestration

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
