Abstract: Urban green space, such as parks, forests, green roofs, streams, and community gardens provide critical ecosystem services, as well as promote physical activity, psychological well-being, and the general public health of urban residents. Recognizing these benefits, many US cities have implemented strategies to increase the supply of green urban space, especially in park-poor neighborhoods. However, urban green space strategies may be paradoxical. Strategies that are “just green enough”, and that protect both social and ecological sustainability, deserve more attention, as the creation of new green space can lead to gentrification and displacement of the very individuals it is intended to benefit.View this article featuring Jennifer Wolch on “eco-gentrification”.
