The purpose of this presentation is to introduce the recently completed work that aimed to develop an integrated robust methodology by embedding the Farmland Bird Indicator (FBI) - one of the most consolidated Common Agricutural Policy indicators for years - into the agricultural economic model CAPRI. This methodological development may then be used to assess the impact of the CAP and other policies on conserving relatively common and widespread farmland birds. Using data from the Pan-European Breeding Bird Monitoring Scheme over the period 1990-2013, our analysis focuses on finding the relations between changes in farmland bird populations and changes in agricultural practices, within four macro-regions. These relations are then linked to changes in agricultural production activities and common reporting indicators from CAPRI such as, crop shares, nitrogen input, livestock density, resulting from policy change scenarios. Projections from the models are derived first to assess the predictive power of the model within each macro-region. We then use the species predicted abundances to calculate the FBI at different spacial scales. By testing the FBI performance in a scenario assessment exercise, it is possible to assess, for example, to which magnitude of changes the FBI is responding.
