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.

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.

“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.

People hoard water. They queue for hours, well into the night, to fill jugs at natural springs. Like mad Christmas shoppers, they clear supermarkets of bottled water. They descend on stockers before they can fill the shelves.

“It’s not often that we have the opportunity to go back to a site 20 years later and see what happened,” said Cynthia Gill, Director of USAID’s Office of Forestry and Biodiversity during a recent Wilson Center event on a retrospective evaluation of the “conservation enterprise” approach to biodiversity. Conservation enterprises are income-generating activities that provide social and economic benefits and help meet conservation goals.
