Why sugar beet leftovers matter at an airport

A harvested field can still offer geese a meal. After sugar beets are lifted, pieces and other crop residue remain on the ground. That food can draw birds into the open fields around Schiphol, including areas between runways. Geese in those areas pose a particular risk: if they take off or cross an aircraft’s path, they can be struck by a plane or pulled into an engine.

Pigs turn cleanup into bird management

Schiphol sends a herd of twenty pigs into recently harvested beet fields to eat what the harvest leaves behind. The aim is not to chase geese off a runway, but to reduce the food that makes nearby fields attractive to them. By removing the residue, the pigs help change the conditions that can bring birds close to aircraft.

The timing matters: the pigs are placed in the fields after the crop has been harvested, when leftover beets are available. It is a targeted way to manage a specific attractant in airport grounds. The striking detail is that the effort to keep geese away begins not with the birds, but with the food left behind in a field.
