Between September 16th and 18th, the 2011 International Green Schoolyard Conference will be held in San Francisco and Berkeley. The green schoolyard movement is growing rapidly and flourishing around the world. Schools are re-imagining their grounds, replacing their extensive paved surfaces with a vibrant mosaic of outdoor learning and play opportunities. Schools in many different countries are leaders in this field, finding innovative ways to weave curricula into their landscapes, diversify their recreational offerings, enhance their local ecology, and reflect their unique location and cultural context.
