Migration Crisis – risk analysis for 2017

Regular passenger flows across external borders will also grow significantly in the coming years, in particular at the air border, due to increased global mobility. Visa liberalisation processes and local border traffic agreements also lead to greater responsibility for border­control authorities. Movements across external air borders are managed through a layered approach, where the border is divided into four tiers. In this context, the physical border is gradually becoming a second ary layer for risk assessment, meaning that checking and screening start well before passengers cross border­control posts at airports.
