IUFRO Spotlight #58: To build a healthier city, build a better forest
Recent innovative studies conducted in Canada and the U.S. show that trees remove air pollution – both gaseous and particulate pollutants – and this has a beneficial effect on human health. And, while the concepts of trees scrubbing the air and cleaner air having beneficial effects are not particularly new, "the innovation derives from linking pollution removal by trees to human health in cities," said Dr. David Nowak of the US Forest Service, and one of the authors of the studies. Dr. Nowak, Coordinator of IUFRO's Research Group 6.07.00 – Urban forestry, also highlights free tools available to aid cities and forest managers globally in assessing their current forest structure and benefits (www.itreetools.org).
