'Growing Power' and the urban farming revolution; A peek inside the doomsday vault for seeds in the Arctic; and the D-I-Y workshop in Berlin for making bikes out of bamboo.
Until now, the US city of Milwaukee has been famous for beer, but Will Allen has planted the seeds of another legacy.
Over the last five years, the Midwestern town has gained a reputation as the home of what many are calling a "good food revolution" - the push to provide locally grown vegetables in the city. This year, the man who began that revolution, Will Allen, was named one of the 100 most influential people in the world by America's Time magazine. DW visited his farm, Growing Power.

Deep under the permafrost of the island of Svalbard, just 1500 kilometres from the North Pole, lies an unusual treasure: Half a million seed samples from all over the world are stored for posterity in the Svalbard global seed vault.
The idea is to protect them from danger. A sort of doomsday vault, where the current diversity of edible crops can be preserved for future generations in the event of a cataclysm – or just the loss of one particular species. The vault is only opened a few times a year. Roland von Bothmer, Professor of plant breeding and genetics at the Swedish University of Agriculture, is one of the few with a key to get in. He took Deutsche Welle on a trip inside.

If you've ever been to Berlin, you've probably noticed that it's a great city for getting around on a bicycle, but that's not enough for some.
Berlin's biking population has exploded in the last ten years, not least thanks to the flat terrain and the bike paths. But for some, conventional bicycles just aren't environmentally friendly enough and they've founded a D-I-Y workshop for making bikes out of bamboo. DW went along to see why – and how.
