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.

Solar farms—just like regular farms—cover large swaths of land, requiring between 3.5 to 16.5 acres per MW of generating capacity. The largest solar plant in the world, the 648 MW Kamuthi facility in Tamil Nadu, India, covers ten square kilometers. But it will be dwarfed by the 3,450 MW facility under construction on China’s Tibetan Plateau, which will span 298 square kilometers when completed. Building these large plants requires fundamentally changing how the land they sit on is used, which—without careful planning—could have negative impacts on the environment and local communities that could potentially lead to conflict. The backlash could not only derail solar projects, but could also fuel resistance to future renewable energy development.

“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.

“The PHE [population, health, and environment] approach addresses the relationship between human health and environmental health, to improve primary healthcare services, conserve biodiversity and natural resources, and develop sustainable livelihoods,” said Sarah Harlan, the Learning and Partnerships Director at K4Health, introducing a recent webinar featuring three PHE leaders from Madagascar, East Africa, and the Philippines.

More than 17 years ago, I came to the United States as part of a refugee group known as the “Lost Boys” of Sudan. In 1987, civil war separated me from my parents for almost 10 years. After 13 years of living in limbo in refugee camps, I was given the opportunity to settle in Tucson, Arizona, where I quickly integrated myself into the American society as a productive citizen. My story demonstrates the resilience paradox: Exposure to prior hardships helps us become more resilient.

“There is a close relationship between fertility rates and health on one hand, and economic growth on the other,” said Peter McPherson, President of the Association of Public Land-Grant Universities and former USAID Administrator, at the final event in a three-part series on the role of population and family planning in supporting economic growth, health, and education.

“Resilience isn’t an outcome, it is a process—and capacity-building is crucial,” said Chelsea Keyser, Deputy Chief of Party for USAID’s PREPARED program, during a recent event at the Wilson Center marking the end of the five-year project. PREPARED (Planning for Resilience in East Africa Through Policy, Adaptation, Research, and Economic Development) developed 14 different tools to help communities adapt to the impacts of the changing environment in the East African region, including unreliable rainfall and rising temperatures.
