Should we eat less rice?
The Food Chain
Jan 16, 2025

Rice is the main staple for over half the world’s population.

The crop has problems though – it is vulnerable to climate change, whether that’s drought or flooding. It’s also a crop that contributes to climate change, as it uses more water than other grain crops and is frequently grown in flooded conditions. Rice production is also a big source of methane emissions.

In this programme Ruth Alexander hears about the possible solutions to these problems. Dr Yvonne Pinto, Director General of the International Rice Research Institute in the Philippines talks about their work developing new varieties of rice, and new more sustainable farming techniques.

One rice company trialling these techniques is Tilda in the UK. General Manager Jean-Philippe Laborde explains what difference it’s made to water and fertiliser use as well as methane emissions.

Given the problems with rice, should we just eat less of it?

Jakob Klein, anthropologist at SOAS University of London explains the Chinese government’s attempts to convince people to eat more potato as a staple food.

And we talk about the cultural importance of rice with listeners in the Philippines and Bangladesh.

Rethinking the potato

Potatoes are having a moment.

Once dismissed as dull, stodgy or even unhealthy, they’re now back, appearing on restaurant menus, in food magazines and across social media feeds.

But the story of the potato goes back much further.

In this episode, Ruth Alexander traces the journey of one of the world’s most familiar foods. From its origins millions of years ago to its place in today’s global food system.

AJ Shehata, senior sous chef at Fallow restaurant in London explains why the potato forces chefs to get creative.

At the Natural History Museum, botanist Sandy Knapp explains how the potato may have been born from a chance encounter between two wild plants in the Andes, an event that made it possible for potatoes to grow underground and spread across new environments.

We explore how the potato became a global food. Potatoes USA president Blair Richardson explains how demand continues to grow worldwide, and how the industry is working to reshape the potato’s image.

We ask whether the potato’s reputation is deserved. Nutrition scientist Candida Rebello shares research suggesting potatoes may be far more beneficial, and more misunderstood, than many people think.

And at the International Potato Center in Peru, scientist Julian Soto works with farmers to conserve thousands of native potato varieties. In the Andes, potatoes are not just a crop, they are part of culture, identity and family life.

From ancient origins to modern revival, this is the story of how the potato conquered the world, fell out of favour, and is now being rediscovered, just as new challenges begin to emerge.
