Wild fauna and flora are facing variable and challenging environmental disturbances. One of the animal groups that is most impacted by these disturbances are pollinators, which face multiple threats, driven to a huge extent by the spread of anthropogenic chemicals, such as pesticides. In an effort to put biodiversity back on a path to recovery and preserve ecosystems and their services, the European Executive Agency (REA) has funded two new research projects under the Horizon Europe framework. Their shared ambition is to provide a better understanding of the exposure routes and toxicological and ecological impacts of chemical pollution on terrestrial biodiversity and ecosystems.
