From the cultural hub of Lahore down to the bustling ports of Karachi, smog is king in Pakistan, with citizens enduring unhealthy air quality for much of the year. The smog, generated mostly by crop and garbage burning and diesel emissions from furnaces and cars, could get worse by the end of this year when Pakistan opens five new Chinese-built coal power plants, funded by a $6.8 billion venture under the China-Pakistan Economic Corridor (CPEC) initiative. These five plants are just the beginning of the Pakistan government’s planned 7,560 MW expansion in coal power, which are CPEC-energy priority projects. “It’s a perfect storm for a pollution crisis,” said Michael Kugelman of the Wilson Center’s Asia Program. “The poor will continue to burn a variety of polluting materials to produce fuel, and now you’re also going to be introducing dirty coal into the mix. Combine that with crop burning in the countrywide and car exhaust fumes in rapidly growing cities, and you’ve got a really smoggy mess on your hands—and in your lungs.”

This year, 2018, marks the 60^th anniversary of a landmark publication by a pair of academic social scientists who first recognized the close relationship between population age structure (the distribution of a country’s population, by age) and development. In Population Growth and Development in Low Income Countries (Princeton U. Press, 1958), demographer Ansley Coale (1917-2002) and economist Edgar M. Hoover (1907-1992) theorized that eventual declines in fertility would transform developing-country age structures. Coale and Hoover demonstrated that these newly transformed age structures would exhibit larger shares of citizens in the working ages, and smaller shares of dependent children and seniors (Fig. 1). This transition, they argued, would someday help lift countries with youthful populations in Asia, Latin America, and Africa out of the low-income bracket.

For this World Cities Day, the UN’s theme calls for “building sustainable and resilient cities.” Cities across the Global South are assessing their physical preparedness against future shocks. Can cities that leave out—or often push out—poor workers claim resiliency? These moves are, in fact, weakening any preparedness. The foundations of truly sustainable and resilient cities lie in their residents’ abilities and agency.

Environmental activists in Brazil are under attack. Last year—the worst year on record—57 of them were assassinated in Brazil, the most dangerous country for environmental activists in the world. The last few years have seen a dramatic uptick in killings of people who take a stand against companies and other actors that commit environmental crimes.

“Historically, resource conflicts have often centered on fuel minerals, like oil. Future resources conflicts may however focus more on competition for non-fuel minerals that enable [modern] technologies,” said Andrew Gulley, Mineral Economist at the United States Geological Survey. America’s 2018 National Defense Strategy says that great power competition is the country’s most important defense challenge. Its key competitor for resources is China. Gulley was among several experts gathered at New America on September 20 to discuss the new competitive space and prospects for conflict or cooperation.

In Judy Brady’s iconic essay, “I Want a Wife,” the feminist activist enumerates the dozens of practical and emotional tasks wives perform as a matter of duty. At the end, she asks: “My God, who wouldn’t want a wife?”

While the World Population Prospects—the UN Population Division’s demographic estimates and projections—will never land on anyone’s non-fiction best-seller list, the latest version holds some noteworthy true stories. And the most remarkable demographic story of all may be Bangladesh’s.

The silver tsunami is approaching: Many countries, not all of them rich, are facing the challenges of an ageing population thanks to growing life expectancies and shrinking birth rates.
