Pittsburgh has become the latest city to be inducted into the Biophilic City network, setting ambitions and commitments to eliminate the use of all pesticides, fungicides and herbicides, to increase the city’s tree canopy from 42 percent to 60 percent by 2030, to pursue  the daylighting of streams in stormwater management efforts and to develop more greenways.

To qualify as a Biophilic City, cities work within a number of guidelines and monitoring indicators:

Guidelines:

• Biophilic cities are cities of abundant nature in close proximity to large numbers of urbanites; biophilic cities are biodiverse cities, that value, protect and actively restore this biodiversity; biophilic cities are green and growing cities, organic and natureful;
• In biophilic cities, residents feel a deep affinity with the unique flora, fauna and fungi found there, and with the climate, topography, and other special qualities of place and environment that serve to define the urban home; in biophilic cities citizens can easily recognise common species of trees, flowers, insects and birds (and in turn care deeply about them);
• Biophilic cities are cities that provide abundant opportunities to be outside and to enjoy nature through strolling, hiking, bicycling, exploring; biophilic cities nudge us to spend more time amongst the trees, birds and sunlight.
• Biophilic cities are rich multi-sensory environments, where the sounds of nature (and other sensory experiences) are appreciated as much as the visual or ocular experience; biophilic cities celebrate natural forms, shapes, and materials;
• Biophilic cities place importance on education about nature and biodiversity, and on providing many and varied opportunities to learn about and directly experience nature; in biophilic cities there are many opportunities to join with others in learning about, enjoying, deeply connecting with, and helping to steward nature, whether though a nature club, organised hikes, camping in city parks, or volunteering for nature restoration projects;
• Biophilic cities invest in the social and physical infrastructure that helps to bring urbanites to closer connection and understanding of nature, whether through natural history museums, wildlife centres, school-based nature initiatives, or parks and recreation programs and projects, among many others;
• Biophilic cities are globally responsible cities that recognise the importance of actions to limit the impact of resource use on nature and biodiversity beyond their urban borders; biophilic cities take steps to actively support the conservation of global nature.

Indicators

• Natural Conditions (eg % of forest or tree canopy cover, % working/living within 300m of green space, area of green roofs, living walls)
• Biophilic Engagement ( eg daily visits to green spaces, flora and fauna eco-literacy, outdoor activity membership)
• Biophilic Institutions, planning and governance, (eg city budget allocated to nature conservation, restoration education)
• Human Health and Wellbeing (% spending 30 mins + in urban nature, in outdoor activities, equitable and just access to nature)

Other aspects of a biophilic city include bird friendly, water friendly (blue urbanism) and dark sky preservation.

Other Biophilic Cities include Wellington, NZ; Birmingham, UK; Victoria Gasteiz ; Spain; Portland, USA and Singapore.
