The future is urban – but is it sustainable?

For decades – centuries, really – warnings have been issued: The burgeoning human population will outgrow the planet’s capacity to sustain us. The formula seems simple. More people equals fewer resources and greater environmental damage.

Population growth “is highly concentrated in what are today the poorest and least well-governed areas of the world,” said George Mason University professor Jack Goldstone at the Wilson Center on December 5.

Goldstone was joined by Suzanne Ehlers, president and CEO of Population Action International (PAI), and Matthew Erdman, population-health-environment technical advisor at USAID, to discuss the implications of seven billion people and counting for the environment as part of the joint Wilson Center-George Mason University Managing the Planet series. [Video Below]

With the start of part two of Circle of Blue and the China Environment Forum’s Choke Point: China series, the focus has broadened from looking more narrowly at water scarcity and energy to including the effects of food security and pollution in China too.

“From an environmental point of view,” said Circle of Blue Senior Editor Keith Schneider, the question is, “can a nation that big, operating at such a scale maintain its sustainability?”

“Why should you consider taking a demography course in college?” That’s the question Joel Cohen, noted demographer and professor at Rockefeller and Columbia University, looks to answer in a 45-minute introduction to demography produced by the Floating University and released for free on YouTube.

In mid-September, the fishing season got under way as usual in Ningbo, on China’s east coast, after the three-month season when fishing is forbidden. Over 2,000 steel-hulled boats headed out to sea. But, on board, there was little cause for optimism.

Where the wide, muddy waters of the Songhua River flow north from Jiamusu to the Russian border, just 150 kilometers (90 miles) distant, the whole of China’s largest treeless prairie sweeps to the horizon. This expanse of fertile grasslands endures the dark fright of cold Siberian winters and the raging winds of Mongolian summers. At night, in the scattered villages, the sky fills with stars so thick and bright that walking along unlit streets is easy.

Quantifying the role population plays in food security is “an incredibly powerful piece of information,” said Kathleen Mogelgaard in an interview with ECSP. Malawi is a case in point.

Mogelgaard saw the connections between food, population, and climate change firsthand on a recent trip to the southeast African country, whose population of 15 million is largely dependent on subsistence, rain-fed agriculture. “One in five children in Malawi is currently undernourished,” Mogelgaard said, and climate change paints a bleak picture for the future.

The water-energy-food nexus seems to be garnering more and more attention in the media and elsewhere, and it’s easy to see why: it’s a relatively simple way to illustrate how interconnected the world is today and the kind of domino-like effects that scarcity can have.
