Keeping things simple could be the answer to the planet’s greatest challenges. We discuss the joys of making, the philosophy of simple living and the importance of doing things properly.

So often these giant conurbations and the challenges they pose to inhabitants, city-planners, businesses, politicians and more, are discussed in pejorative terms. On ‘The World Ahead’ we’re interested in hearing from people whose insights and experience show that bold decisions can make a positive difference – and on a huge scale. We discuss what cities are doing to affect positive change, the expansion of our urban environment and the role that both public and private resources should play in meeting challenges.

In the latest instalment of our special documentary series, which seeks to answer some of the toughest questions that are confronting the world today, we focus on the issue of ageing populations.
