A rose among the thorns in South American cities, few places have been as successful as Medellin in tackling social problems head-on with urbanism, architecture and greening of the urban landscape. Colombia's second-largest city has gone from drug-cartel hovel to urbanist dream. The work is nowhere near done but Medellin can inspire every other city in the world with its visionary political and social choice and its strong network of urban activists.
Often perceived as cold and expensive, Paris is a mythical city, one of luxury, gastronomy and haute couture. But beyond the clichés of the Eiffel Tower, there is another Paris - one of solidarity, wittiness, and repurposing public space. This Paris revolves around change, inspiring solutions big and small to improve everyday life for its citizens. It hopes to minimize traffic, give a new life to the banks of the Seine River, and provide adequate lodging and a sense of belonging.
Mikael Colville-Andersen lands in Toronto to meet the urban heroes working to make Canada's largest city more livable.

With 239 neighbourhoods and people coming from all over the world, it's a multi-faceted and profoundly diverse metropolis.
A chaotic mix of skyscrapers, street markets and hidden alleyways, Bangkok is a vibrant hub of life, buzzing day and night. Dubbed the Capital of Gridlock, Bangkok boasts traffic that is among the worst in the world. The city's future seems paralyzed by recurring political upheavals, but social instability hasn't undermined the locals' fierce will to better their city. They're fighting back, not with violence but with creativity and ingenuity.
Few modern cities evoke as much division as Tel Aviv, with its reputation as a laid-back and permissive party town in a hotbed of conflict and turmoil. The problems of a rising cost of living, deficient public transport, and development conflicts are often put aside in the face of cyclical religious and cultural struggles that have marked its complex history. But people from both sides of the political and cultural divide are working together to create a more functional and united city.
Modern Tokyo is a fascinating urban mystery. The largest urban agglomeration in the world, it is home to 38 million people - more than the entire population of Canada in one city. On the surface, Tokyo feels like an oversized, human-built environment, full of endless rows of towers, glittering neon and fast-moving citizens. But if you dig deeper, this megacity is much more than its impressive size.
On the southwest coast of South Africa, Cape Town makes headlines for its laidback lifestyle and natural beauty. But beneath the sales pitch, traces of a dark past still linger.

Mexico City, the largest city in the Western hemisphere, faces challenges ranging from social and economic inequity to environmental issues to its vulnerability to earthquakes.

For the past decade, Copenhagen has consistently ranked near the top in dozens of annual global livability surveys. Is Denmark's capital the ultimate life-sized city? Is this model scalable? Urban design expert Mikael Colville-Andersen explores his own city and meets the people working daily to make it live up to its reputation.
Once considered the bland financial capital of Italy, Milan is proving its capacity to redefine itself. An industrial past had left almost indelible scars on the urban fabric. But Expo 2015 sparked change: skyscrapers, new public and private initiatives, and innumerable urban renewal projects have since popped up on every block. Decades of open-mindedness, and of open doors to immigration, have made Milan the most multicultural hub in all of Italy.
The southwestern Ontario city of Windsor has always lived in the shadow of its big American neighbour, Detroit, only 3.6 kilometres away. People cross the border every day for work or leisure. In a matter of decades, Detroit went from one of the most prosperous U.S. cities to one of the most distressed, culminating in the municipality's bankruptcy in 2013. How has this affected Windsor, a city trying to make a name of its own in Canada?
Although Montreal could be described as half Paris, half Brooklyn - it is after all the most populated francophone city in North America - the city has an identity of its own. Made up of a peculiar mix of creative citizens, cobblestones and potholes, Montreal is not the biggest, nor the richest or boldest. But it's one of the best cities to live in, and it certainly is a happy underdog.

Los Angeles is home to over 13 million people who collectively make up one of the most multicultural places in the world; with over 80 neighborhoods making up a rich, diverse hub, LA's polycentrism is certainly its greatest asset.
Germany's capital city, Berlin, is a place of many contradictions. In 1961, the city was reunited, but decades of isolation left deep-rooted urban and social scars and lasting international repercussions.
Calgary, Canada's oil capital and Alberta's biggest city, is more often associated with the Stampede, cowboys, oil drilling, suburban sprawl and highways. But its economy is now diversifying, and so is the population.
