Predicting the shape of our future populations is vital for installing the infrastructure, welfare, and provisions necessary for society to survive. There are many opportunities and challenges that will come with the changes in our populations over the 21st century. We must plan for the following challenges, the impact of climate change and urbanisation, and the difficulty of feeding 10 billion people, and consider ways in which we can prepare for, and mitigate against, these challenges.

Professor Sarah Harper, Director of the Oxford Institute for Population Ageing, will explain how population change will transform the world and looks at what we can do to meet the challenges that lie ahead.
