How and what we eat, and where our food comes from, these everyday choices that we often think very little about, have become increasingly relevant to climate change.
With a global population projected to reach 10 billion by 2050, it is not unreasonable to ask: how are we going to feed all these people... and without causing more damage?
In this episode we’ll cover everything from how climate change will affect the way we grow and eat food, to the pros and cons of ‘non-poo’ fertiliser. Sound appetising?
Giles Oldroyd, professor of plant science at the new Cambridge Crop Science Centre, Helen Anne Curry, lecturer in the history of modern science and technology, and developmental economist, Shailaja Fennell, helped us connect the dots between food and climate change. They discuss how we ensure people around the world will still have food to eat as the climate becomes more unpredictable.

My current research focuses on the history of efforts to understand and use crop diversity as a resource for agricultural development. In August 2020 I launched the project 'From Collection to Cultivation: Historical Perspectives on Crop Diversity and Food Security'. This project has its origins in my investigation of history of genetic conservation, especially the preservation of seeds and other plant materials in seed and gene banks. It is also the subject of my current book project, Endangered Maize: Indigenous Corn, Industrial Agriculture and the Crisis of Extinction.
