"Asphalt to Ecosystems: Design Ideas for Schoolyard Transformation" (Sharon Danks, New Village Press, 2010) makes the case for "green schoolyards" and for improving the ecology, learning, and play potential of school grounds.
It is intended as a resource and idea book to inspire schoolyard designers, teachers, parents, school principals, and other members of school communities. The book is filled with examples that show that many things are possible on school sites, and supports that idea with approximately 500 colorful photographs from roughly 150 schools in 11 countries. The book is fully indexed and includes an extensive resource section and bibliography.
