Feeding the world and the Green Revolution

In February 2024, the renowned Indian geneticist Dr. MS Swaminathan was posthumously awarded the country’s highest civilian honour, the Bharat Ratna. This was in recognition of the dramatic increase in the yields of food staples, such as rice and wheat, that Indian agriculture experienced under his stewardship of the ‘green revolution’ in the 20th century. That revolution is credited with saving many people from hunger and malnutrition across Asia and Latin America. And yet, half-a-century on farmers’ incomes in Africa, Asia and Europe are falling and in many countries farmers are on the streets protesting. At the same time, the environmental impacts of intensive food production are becoming increasingly clear. So do we need a new ‘green revolution’? And is the use of the latest agricultural technology, from robots to AI the answer?

Rajan Datar discusses the past and present of food growing with Professor of Economics Douglas Gollin, crop scientist Professor Nigel Halford, historian of science Dr. Madhumita Saha, robotics project manager Andreas Hofland and listeners from around the world.

The unfolding history of the magazine

When magazines first emerged, they were the preserve of an elite who could afford to pay for them. But as time went on, the cost of paper fell, printing technology became more streamlined, literacy improved and would-be publishers spotted an opportunity to connect with audiences hungry for information and entertainment.

Magazines found a place to appeal to all types of interest, in the same way that the internet does today. In their heyday they attracted some of the best writers such as Charles Dickens and Ernest Hemingway, sometimes acting as a vehicle to establish literary careers. Later magazines were to become the go-to place for quality photography and design.

Falling advertising revenues have largely contributed to the decline of printed magazines, as well as editions moving online. However some titles have found a way of reinventing themselves in the 21st century.
