On the stone planet Earth, a layer has been added since the beginning of life, 3.9 billion years ago: our  between 5 and 20 cm thick layer of top-soil. In this thin layer, the major part of all biological activity of Earth is going on. Through our various actions  we are either nourishing or depleting this layer. The interaction of microorganisms in the top-soil and life above means without exaggeration everything for life’s further progression.
The lack of organic matter brought back to the soil  in modern large scale farming is rapidly destroying invaluable top-soil worldwide, putting the whole foodproduction of the future at risk. Recent years guerilla gardening is a fantastic movement, addressing many of the problems connected to industrial agriculture and urban – rural disconnection. For the show Hungry city, Kultivator will make an action of “guerilla composting”, that adds to this practice, and encourages people to feed – back nutrition to the ground they live on.

Prior to the opening, we will dig down a few wormtowers on green spots nearby the exhibition space/area. Inside the exhibition, we will set up a “worm campaign office”, where information on the wormtowers, (how they work, how to make them, why its good, etc) will be displayed, as well as tools, materials and of course worms. During the opening weekend , we will ask visitors to join us and make their own tower to take out and install somewhere where they think it is good to feed back some nutrition to the soil. The worm office will also have a presentation of Kultivators previous works by the poster series “Post revolutionary exercises; ten suggestions of how to prepare for a new order”, reflecting previous projects, from now back to 2006. The Guerilla composting will be the 11:th of these exercises, and a new poster will be made for it. After we leave, for the rest of the exhibition period,  the worm office will still be interactive, for those who wishes to make their own wormtower and guerrilla composting action.

A worm tower (vermicompost) is a perma culture method of composting, that simply uses free-ranging compost worms to break down organic waste and then move those nutrients out into the surrounding. A pipe, for example a drain pipe, is dug into the ground, sticking up 10 – 20 cm. Dry organic matter, like leaves or grass, and worms are inserted, and on this you can throw kitchen waste, like leftover food, potato peel, etc. The worms eat the waste and crawl out of the pipe again to spread the processed matter further. The method is often used to direct nutrition to one certain tree. A lid prevent birds or rats from picking the waste out from the top.
