Parking Lots to Parks: Designing Livable Cities
Earth Policy Insitute
“The world’s cities are facing unprecedented challenges. In Mexico City, Tehran, Kolkata, Bangkok, Beijing, and hundreds of other cities, the air is no longer safe to breathe. In some cities the air is so polluted that breathing is equivalent to smoking two packs of cigarettes a day. Respiratory illnesses are rampant. In many places, the number of hours commuters spend sitting in traffic-congested streets and highways climbs higher each year, raising frustration levels.
In response to these conditions, we are seeing the emergence of a new urbanism, a planning philosophy that environmentalist Francesca Lyman says “seeks to revive the traditional city planning of an era when cities were designed around human beings instead of automobiles.” One of the most remarkable modern urban transformations has occurred in Bogotá, Colombia, where Enrique Peñalosa served as mayor for three years. When he took office in 1998 he did not ask how life could be improved for the 30 percent who owned cars, but for the 70 percent—the majority—who did not.
Peñalosa realized that a city with a pleasant environment for children and the elderly would work for everyone. In just a few years, he transformed the quality of urban life. Under his leadership, the city created or renovated 1,200 parks, introduced a highly successful bus-based rapid transit system, built hundreds of kilometers of bicycle paths and pedestrian streets, reduced rush hour traffic by 40 percent, planted 100,000 trees, and involved local citizens directly in the improvement of their neighborhoods. In doing this, he created a sense of civic pride among the city’s 8 million residents, making the streets of Bogotá in this strife-torn country safer than those in Washington, D.C.
In espousing this new urban philosophy, Peñalosa is not alone. Jaime Lerner, when he was mayor of Curitiba, Brazil, pioneered the design and adoption of an alternative transportation system that is inexpensive and commuter-friendly. Since 1974 Curitiba’s transportation system has been totally restructured. Although 60 percent of the people own cars, busing, biking, and walking account for 80 percent of all trips in the city.
When 95 percent of a city’s workers depend on cars for commuting, as in Atlanta, Georgia, the city is in trouble. By contrast, in Amsterdam 35 percent of all residents bike or walk to work, while one fourth use public transit and 40 percent drive. In Paris, fewer than half of commuters rely on cars, and even this share is shrinking thanks to the efforts of Mayor Bertrand Delanoë. Even though these European cities are older, often with narrow streets, they have far less congestion than Atlanta.”
Contrast this with the Public Health Committee‘s April report to the NZ Minister of Health, Healthy Places, Healthy Lives: Urban environments and wellbeing, which highlights the range of negatives caused by urban planning in NZ, particularly with reference to health impacts. It urges alternatives to create a healthy urban environment:
If designed appropriately, urban form and transport can increase physical activity, improve air quality, reduce road traffic injuries, increase social cohesion, and achieve maximum health benefits from services and facilities. Urban form can also help create a sense of place. This is important for the health and wellbeing of all populations living in urban areas, especially Maori.
