The paper, published in the Proceedings of the National Academy of Sciences (PNAS), is the result of a collaboration between scientists from 28 countries. They analysed abundance indices of 170 bird species that have been consistently monitored over 37 years in more than 20,000 study plots. The authors linked the bird indices to publicly available environmental data from sources such as Eurostat, the European Environment Agency, and the FAO, including information on land use and climate.

The data collected leaves no doubt: the main driver of environmental change leading to serious biodiversity loss is agricultural intensification.
