In May 2016 the Swiss company ‘UrbanFarmers’ officially opened its second
aquaponics farm, this time in The Hague, the Netherlands. Compared to the first
farm in Basel (Switzerland) this second farm was more challenging: on the top
floor and roof of a six–floors industrial building in The Hague. The farm produces
12 tonnes of tilapia and 40 tons of vegetables per year.
