Earlier this month, the United Nations released a final report on the Millennium Development Goals (MDGs), the framework that has guided global development efforts for the last 15 years. The document examines each of the eight MDGs and finds that “despite many successes, the poorest and most vulnerable people are being left behind.” As one of the first global poverty reduction movements nears its end, the report calls for better data collection practices to create a post-2015 development agenda that can overcome the MDG’s shortcomings.

In 2007, the world crossed a threshold:  for the first time in human history, the majority of people lived in urban areas. Today, Africa and Asia are the only remaining continents where the rural population outnumbers urban, but they are urbanizing at unprecedented rates. This rapid growth is a double-edged sword. While urbanization spurs economic opportunity and often increases access to infrastructure, it is also widening disparities in health and development, according to a new data sheet by the Population Reference Bureau.

“With current neglect of family planning, the UN’s recent projection of a 2100 world population of up to 12.3 billion is a possibility,” says a report from the University of California, San Francisco’s Bixby Center for Global Reproductive Health. Increased voluntary family planning efforts are needed, the authors contend, to meet existing demand for contraceptives, stabilize the threat of global food insecurity, and reduce carbon emissions that contribute to climate change.

Although treating wastewater generally ranks alongside police and fire safety, schools, and transit as the top priorities of any sensible city hall, new ideas about cleaning up sewage almost never attract headlines or TV airtime. In its 90-year history, for instance, The New Yorker, the most urbane and expansive magazine in the country, has never published a feature article on sewage treatment.

In March 1999, not long after he was sworn in as the 47^th mayor of Oakland, Jerry Brown called Lesley Estes, the supervisor of the city’s watershed protection program. Brown, who is now California’s governor, wanted the city staffer he called “Creek Lady” to describe the most formidable ideas she had to conserve natural areas, make parks more beautiful, and clean up the city’s waters.

Karachi, the world’s second largest city by population, is emerging from the grips of a deadly heatwave. A persistent low pressure system camped over the Arabian Sea stifled ocean breezes and brought temperatures in excess of 113°F (45°C) to the city of 23 million people in June. The searing heat disrupted electricity and water service, making life nearly unbearable. All told, officials estimate the heatwave killed at least 1,200 Pakistanis, more than twice as many as have died in terrorist attacks this year.

“Tackling climate change could be the greatest global health opportunity of the 21^st century,” asserts the newest report by the Lancet Commission on Health and Climate Change.

A new article from the Wilson Center’s own Roger-Mark De Souza explores how population trends can bolster community resilience in the face of climate change and other security threats. De Souza argues that demographic trends such as age structure help determine how well a population is able to respond to and bounce back from shocks, especially environmental ones like drought and famine.
