A new collaborative study published in the Journal PNAS finds that agricultural intensification, in particular pesticides and fertiliser use, is the main pressure for most bird population declines, especially for invertebrate feeders.
Using ‘the most recent and largest empirical dataset ever assembled for Europe to investigate the effect of anthropogenic pressures’, the study highlighted the predominant detrimental impact of agriculture intensification on avian biodiversity at a continental scale over climate change, urbanisation, and forest cover changes.
