Theme: Urbanism Unlocked

Today, some 56% of the world's population lives in cities and this number is expected to rise to 68% by 2050. The shift in residence away from rural areas is reshaping our world and redefining the ways that humans are interacting with each other and their physical spaces. With the impacts of climate change and population density reaching new thresholds, the world needs creative solutions more than ever before. At TEDxRiverdaleCountrySchool we want to take you on a journey of ideas, stories and innovations that will unlock our conception of urbanism and provide hope and optimism for a sustainable future.
