Implementation model


A short description of the NBS project

In the early 1970’s, Liz Christy and the original band of green guerillas decided to do something about the urban decay they saw all around them. They threw “seed green-aids” over the fences of vacant lots. They planted sun flower seeds in the centre meridians of busy New York City streets. They put flower boxes on the window ledges of abandoned buildings. The green guerillas began rallying other people to use community gardening as tool to reclaim urban land, stabilize city blocks, and get people working together to solve problems. Soon, dozens of community gardens bloomed throughout New York City, and neighbours formed vital grassroots groups. Today, more than 600 community gardens serve as testaments to the skill, creativity, and determination of New York City’s community gardens. They grow food for their families and neighbours. They connect city kids to the earth. They give seniors cool green spaces to pass summer days. They allow people to kneel down together and garden in the city. The key principals that the Green Guerrillas live and operate by are openness, transparency and the sharing of knowledge.
