These services help to reduce the incidence of infec- tious diseases and respiratory disorders, and assist with adaptation to climate change. Access to nature offers many other direct health benefits, including oppor- tunities for physical activity, reduction of developmental disorders and improved mental health. Economic valuations of green spaces in several cities globally have found that nature provides billions of dollars in cost savings for health services. Protected areas are increasingly common in, and around, cities to protect biodiver- sity and ecosystem services, including these benefits for health. Many cities are also launching programmes to enhance the health and environmental benefits of parks, based on a model of Healthy Parks, Healthy People, by Parks Victoria  in Australia. Partnerships between conservationists, city planners and health authorities are criti- cal to maximise these benefits. In some places, medical professionals prescribe time in nature, and some cities specify standards for urban green spaces to enhance their health benefits. The United Nations  Sustainable Development Goals provide an important global framework for such partnerships from global to local level.
