is an economist and co-founder of Stadtgarten, a community-based gardening initiative that encourages would-be gardeners to use this public space to grow and harvest their own vegetables and share in the spoils: over 1000 servings of fresh, organic fruit and veg last year! She is also the co-creator of Mundraub, an internet platform that enables users to share the location of fruit trees lying on common or non-farmed land so they can be tended and harvested. Both projects have been awarded prizes by the German Council of Sustainable Development.
