What the photographers tried to communicate was a need: both the urgent need for infrastructure that leads to more resilient, sustainable cities, or a need to aspire to greener ideals of building sustainable communities for all.
There is no better day than today, World Cities Day, for us to share with you the 10 finalists – including 3 winners and an honorable mention for climate action – of the photo competition.
In the winning photo by Yanick Folly, one can practically feel the chaos of a city in Benin, the smell of exhaust fumes as cars crawl up alongside motorcycles and pedestrians down narrow alleyways.

The photo is also a reminder that cities are made of people. Any set of solutions for “sustainable cities” will have to make sense to a city’s inhabitants, who tread its streets daily.
In other photos, the aspiration is palpable.
Many of the photographers are nationals of developing countries from all over the world. Yet quite a few of them shared photos of cities we regard as environmentally friendly: Singapore, Amsterdam, London, and Paris... We saw many photos of parks in developed countries, and heard the same message: These green spaces and pedestrian walkways are what we want in a city.

Many photos also reflect the vast difference between the aspirational city, and what most people actually live with.
We received photos of what many of us may categorize as rural areas, but we should reconsider these preconceptions: some “cities” in developing countries are little more than makeshift towns.
So, it is all the more reason why we are excited about this winning photo by Oyewolo Eyitayo from Nigeria. You might think this is an uneventful photograph of a typical urban suburb. Except that the half dirt roads are lined with solar panels.
Already, more than half of the global population — nearly 4 billion people — live in urban areas. Two decades from now, that number will grow to 5.5 billion — more than 60 percent of the world’s population. At the same time, the total built-up area of the world’s cities is expected to be double by 2030 what it is today, if not more.
Can nature help cities address the twin problems of air that is too dirty or too hot? Based on a new report released by The Nature Conservancy – in collaboration with C40 Cities Climate Leadership Group - the answer appears to be a qualified “yes.”
The Planting Healthy Air report identifies the potential return on investment from tree planting in 245 global cities, which currently house about a quarter of the world’s urban population. By collecting and analyzing geospatial information on forest and land cover, particulate matter, and population density and leveraging existing literature, the study estimates the scope of current and future street trees to make urban air healthier. The benefits that trees could afford to cities will be even more crucial in the future, the study finds, as a quarter million people could die each year because of urban heat by 2050, unless cities take proactive steps to adapt to global warming.
