World Urban Forum Highlights Opportunities for Sustainable Cities
Many cities face increasing pressure. The urban population has increased five-fold since 1950. Vehicle ownership is on course to double by 2050, while traffic accidents lead to 1.3 million deaths each year. Cities emit approximately 70 percent of global greenhouse gas emissions. All of this is even more staggering when you consider that 1.5 billion people will move into cities in the next two decades, bringing the total to 5 billion worldwide.
The reality is that well-designed cities can generate jobs, innovation, and economic growth for all. But when designed poorly—with too much sprawl, waste, and inefficiency—they can divide cities and exacerbate pollution, inequality, and political instability. Moreover, poor design has long-term consequences given that urban infrastructure often lasts decades.
Against this backdrop, some 25,000 people have gathered in Medellin, Colombia, for the UN Habitat’s World Urban Forum this week. The key question they face is: How can cities drive growth that is inclusive and sustainable at the same time?
