Africa is a centre of world history — a fact that's been deliberately obscured, says journalist Howard W. French. In this talk based on his book, The Second Emancipation, he explores the surprisingly early seeds of 20th century Pan-African thought, and how Kwame Nkrumah of Ghana went from reluctant student to influential leader of a free Ghana.

From Joan of Arc to Kim Kardashian, and Davy Crockett to Donald Trump, celebrity culture has deep and wide roots. Famous people who elicited Kardashian-level feelings of love and hate in the public were present centuries ago — long before screens and social media. Though, as we find out in this podcast, they all share similar qualities. *This episode originally aired on June 30, 2022.

Heated Rivalry, Love is Blind or Boyfriend on Demand all underline the global appetite for passionate swooning. But let’s not forget the source for all of it: the romance novel. It may have a reputation problem but sales in 2023 reached 39 million copies or romance fiction globally — ringing in at $1.5 billion dollars. The books and readership continue to evolve as popularity increases. What is it about romance novels that women are drawn to? Is it unhealthy escapism, harmless fun or a kind of opiate? IDEAS looks back to a 1992 episode called Paperback Love to understand the enduring acclaim of romance novels.

In the days before her medically-assisted death, journalist Elaine Dewar made it her mission to finish writing her book revealing ignored history. For more than three years, the author investigated how Canada's health care system cruelly mistreated Indigenous people — including forcing them to use segregated hospitals. Dewar's extensive research uncovers not only a shameful past, but that our collective obliviousness to it all was deliberately manufactured.

For thousands of years, estuaries were central to Indigenous agriculture on the West Coast. Then, when colonists arrived, they diked many of these ecosystems to create western farmland. Now, Cowichan Tribes is working with a group of scientists and conservationists to restore an estuary as an ecosystem and a food system — and the project has sparked an unexpected controversy. At the heart of the debate are two questions. What does agriculture really mean? And when the waters start to rise, do we work with them, or against them?

This is the second and final part of this series, What the River Wants to Be. Listen to Part One.
