World cities day: growing urban poor populations face unique nutrition challenges

For the first time in history, more than half of the world’s population lives in cities. This figure is expected to rise to 68 percent by 2050, presenting a host of new challenges and opportunities. The theme of this year’s World Cities Day (Oct. 31) is “Building Sustainable and Resilient Cities.” Sustainability and resilience are often defined in terms of cities’ capacity to adapt to rapidly-changing technological, environmental, and economic realities. Resilience also relates to the preparedness of cities to respond to global climate challenges and population growth. But what about the resilience of city dwellers?
