“We know that exposure to nature enhances our well-being, but we know less about the specific features that create these positive effects,” said MaryCarol Hunter, ASLA, University of Michigan, at the ASLA 2015 Annual Meeting in Chicago. A set of fascinating studies by Hunter and Marc Berman, a psychologist and neuroscientist at the University of Chicago, are beginning to converge on what those feature are. The goal is to translate knowledge of these features into design guidelines landscape architects and other designers can apply. All of this research is happening under the rubric of the TKF Foundation, which has invested millions over the past two decades creating more than 130 small, healing parks and financing research studies on the health benefits of green spaces in dense, urban areas. The TKF Foundation wants to know: with increasingly limited space in cities for green space, how can we have the biggest impact?
Humans evolved in wild lands, but we mostly live in urban environments now. While we inherently connect with our ancestral landscapes, we are constantly exposed to cacophonous city life. Wild landscapes can’t be fully translated into urban environments, but “some elements can be transported to downtowns. We can get close to the effects of wild places,” said Hunter.
