Blue house, open door - Summer dreams for city birds.

Today I read that the Stadtfarm in Landschaftspark Herzberge has to close for good due to income losses - missing sales to the catering industry, fewer customers, and rising energy costs.¹ That’s a real loss for the area, because the concept of aquaponics is really fascinating.² By utilizing natural cycles, the breeding of edible fish (African catfish³) is combined with the cultivation of vegetables. The liquid excretions of the catfish serve as valuable plant fertilizer: they pass through a biofilter, where bacteria convert the ammonium into nitrate. The water is then used to feed tomatoes, peppers, chilies, and herbs, before cycling back to the fish. It’s a closed-loop system that works without soil or additional irrigation.⁴

Every evening when the sun goes down, I see the spotlights and bright glow of the Christmas market near Frankfurter Allee. It feels like a foreign object that’s suddenly materialized, distorting the whole area. I wonder if they chose extra spotlights just because cultural events and folk festivals have an exemption in the EnSikuMaV¹. I can totally understand why people living directly in front of the market might be upset² - especially on cold, foggy nights when the light is just eerie and overwhelmingly bright.

Two weeks ago, a friend sent me an article¹ about the current exhibition at Schloss Biesdorf featuring the works of Jürgen Wittdorf (1932–2018). The idea of homoerotic art in the GDR intrigued me, so we decided to visit. For me, it was a fascinating experience - a retrospective of Wittdorf’s work, and to my surprise, I recognized some of his illustrations. One room later, I found out why: he was the illustrator for the children’s book “Tiere im Zirkus” by Wladimir Durow², a book I still own, though I’d never known anything about the artist behind it.

K is for Kumulus. Sometimes the sky and the city are on the same wavelength.
