Some 52 percent of the world’s population lives in cities, a proportion that will only grow throughout the next few decades. Understanding the health challenges facing urban residents is crucial for those who seek to improve human health, especially since many of these challenges differ from those facing inhabitants of rural areas, where global health resources have traditionally been concentrated. At a private meeting on March 4 at the Wilson Center, experts described how factors ranging from climate change and greenhouse gas emissions to reproductive health and rights impact urban health.

Climate change and conflict can create a self-reinforcing feedback loop: Climate change exacerbates existing conflicts, while conflict makes adapting to climate change more difficult, said Janani Vivekananda of International Alert at the Wilson Center on February 7. [Video Below]

“My income is just right to feed us three times a day,” Jason Bostero told Sam Eaton in the rural Philippine village of Humayhumay. “It’s really, really different when you have a small family.” Eaton traveled to the Philippines to report on the connections between food security and population for Homelands Productions, creating a short film and radio piece that ran on NewsHour and Marketplace as part the Food for Nine Billion series last year. [Video Below]

Despite progress over the years, Ethiopia’s Guraghe zone, located in the Southern Nations, Nationalities, and People’s Region, faces many development challenges. As senior monitoring and evaluation officer in the Guraghe People’s Self-help Development Organization (GPSDO), I have been working in this region for more than five years trying to reduce poverty and improve socio-economic development. The organization as a whole has been here for more than 50.

Carbon offsets have fallen in and out of favor since they were established with the Kyoto Protocol in 1997. Critics say they allow wealthy organizations to placate consumers and claim their products are “green” without making any real, lasting changes. But, if the scheme works properly, some action is supposed to be taken somewhere, so what is it like at one of these credit-producing organizations?

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]

Without decisive action, global temperatures could rise by at least four degrees Celsius (seven degrees Fahrenheit) by the end of the century. A new World Bank report says that such a world would be “so different from the current one” that it would be difficult to even anticipate the challenges we would face.
