Global change requires new fire management to preserve biodiversity

More than 4,400 terrestrial and freshwater species are threatened by changes in the fire regime. While many species are at risk by the increased frequency and intensity of fire, its suppression can be harmful to some life forms and ecosystems.

Phosphorus, once only a nutrient, has become a contaminant on a global scale

Freshwater ecosystems near densely populated areas have levels of phosphorus which are very high and out of balance with nitrogen levels. This has resulted in altered ecosystem functioning, lower water quality, and has made water conservation more difficult.

CO2 absorption in European ecosystems depends on two major climatic phenomena

The worst scenario occurs when NAO and EA are in opposite phases. This ocurred in the first few years of the previous decade and during this period, the CO2 uptake was below average. Recently, NAO and EA were in the same phase and ecosystems have been able to remove more carbon from the atmosphere.
