Due to its favourable location, the Netherlands harbours at times large numbers of migratory birds, and bears an international responsibility to accommodate them. Many of these birds spend the summer above the Arctic circle. Because climate changes faster in the Arctic than elsewhere, the question arises whether these birds are under threat. In this project, we combine the latest climate models with existing and new data on migratory birds and their food web in the Arctic. We assess the vulnerability of these migratory bird populations to climate change, and which mitigation measures are possible outside the breeding range.
