Green farming: food production in the city

The Erbenheimer supermarket tries to combine urban food production and the supply of the urban population. To this end, herbs are grown on the roof of the market. In the basement, the supermarket breeds fish that are then sold in the shop. In an interview with Merkurist, Benjamin Kraff, an employee of the Spatial and Infrastructure Planning Department, reports on the contribution that green agriculture can make in the course of sustainable urban development.
