Off the coast of Rotterdam, Netherlands, a floating farm is providing locals with a fresh supply of milk.
The farm-boat-combo, created by a company aptly named Floating Farm, has been selling the milk of its 35 seafaring cows since May, CBC News reports.
The mostly automated operation is intended to help make cities more self-sustaining in the face of a changing climate that threatens the area’s infrastructure.
The farm is a three-story barge, according to CBC. The cows live on the top floor. They can wander ashore when the barge is docked—eating local grass clippings, potato peels, and beer broth, and supplying manure to nearby fields.
A staff of two maintain the farm with three classes of robots: milkers, feeders, and poop scoopers.
“The entire process is completely automated,” CEO Peter van Wingerden told CBC. “What we are trying to do here is produce the highest yield of food with less people.”
