Forest

Let’s talk about risks: if your forest were a country, which one would it be?

Japan is among the countries that are best prepared for natural disasters, those with the most hospital beds, the highest levels of education, prevention plans, adapted urban designs and so forth. Why, then, is it also one of the countries whose inhabitants are most at risk from such disasters?

Climate change-induced decline in winds could delay leaf-fall at high latitudes

Wind dynamics need to be factored into studies that measure the impact of climate change on the rhythms of nature. A study published in PNAS and co-authored by CREAF-based CSIC researcher Josep Peñuelas concludes that a decline in winds is currently benefiting plant productivity.

Nutrient-rich forests absorb more carbon

The study, published in the journal Nature Climate Change, showed that forests growing in fertile soils with ample nutrients are able to sequester about 30% of the carbon that they take up during photosynthesis. In contrast, forests growing in nutrient-poor soils may retain only 6% of that carbon. The rest is returned to the atmosphere as respiration.
