North Korea is considered one of the most secretive countries in the world. It is officially an atheist state. The ruling party sees religion as a threat to its authority. Instead North Koreans are expected to show complete devotion to the ruling Kim family, who many view as godlike. There are believed to be a small number of Christians practicing in secret inside the hermit kingdom, but entire families can be sent to prison camps for practicing religion. Even owning a Bible can lead to detention or even death. There are an estimated 33,000 North Korean defectors living in South Korea. The exact number of North Korean Christians living in the south is unknown, but it is believed that a significant number of defectors now identify as Christians. BBC Correspondent Danny Vincent travels to the South Korean capital of Seoul to meet a family of defectors he first met a decade earlier while fleeing Northern China.

In 1900, German colonial officers executed 19 Tanzanian leaders, including Akida Kiwelu, and shipped their skulls to Berlin for scientific study. Thousands of such skulls and ancestral remains stolen from Germany’s past colonies are still kept in Berlin museums to this day. In an administrative building in Berlin, Zablon Kiwelu encounters his grandfather’s skull for the first time. DNA testing confirmed a genetic match to this skull, held in an anthropological colonial-era collection of thousands of skulls known as the S-Collection. But despite proof of his heritage, Zablon cannot bring his grandfather home for a proper burial.

Observers are calling this possibly the biggest human trafficking event in modern times. Hundreds of thousands of people recruited – usually under false pretences - to work in massive facilities in the border areas of Myanmar, Cambodia and Laos, to promote fraudulent investment schemes and romance scams to unsuspecting citizens around the world. The scams, run by criminal gangs, are thought to be making tens of billions of dollars every year. Those recruited often find themselves, trapped, beaten and tortured. Ed Butler travels to Thailand’s border with Myanmar to investigate the scale of the trade, to speak to survivors and to some of those still involved, and to explore what role the ongoing civil war in Myanmar is playing in fuelling this apparently burgeoning criminal trade, beyond the reach of international law-enforcement.

For over 25 years Antonia Quirke has made programmes and written articles about film. After a chance comment during an interview, she was offered a small part in a screen adaptation of Jim Crace’s novel Harvest, directed by Athina Rachel Tsangari, one of the celebrated instigators of the surreal, unsettling cinema movement known as the Greek Weird Wave. Filmed over the course of one tempestuous summer on location in the remote Scottish Highlands, little did she know that she was to end up having to perform a particularly gruesome act of violence during a pivotal scene. And then watch that moment screened for the first time at the Venice Film Festival. This programme contains content that some listeners may find upsetting.

In 2019, British-Nigerian comedian Emmanuel Sonubi suffered from a near-fatal heart failure whilst on a comedy tour of Dubai. He had a condition called dilated cardiomyopathy, which means his heart was not pumping enough oxygen around his body, and he might need an urgent transplant. In the years since Emmanuel's condition has been controlled through medication but the threat of a heart transplant still looms large – as does the shortage of donors from people of his background where he lives in the UK. Emmanuel examines the cultural attitudes which stop people from taking part in organ donation and transplantation. He also hears from Dr. Beatriz Domínguez-Gil, director general of Organización Nacional de Trasplantes and Lalitha Raghuram, one of the leaders of the MOHAN Foundation, which helps spread awareness of organ donation across India.

The number of adults getting baptised in France has tripled in the last three years. Why are so many more adults joining the Church in France? We meet two of France’s new Christians, one baptised this Easter, one last Easter, and hear the strong stories they have to tell about the path they took and ask whether Catholicism is changing from a religion that baptises infants to one that baptises adults and whether that is a good thing.

Researchers in Morocco are developing dry-land agriculture at ICARDA (the International Center for Agricultural Research in the Dry Areas). It is home to a gene bank, in which around 150,000 different seed-types are kept in perfectly calibrated cold vaults, and duplicated to protect them from ‘fire, earthquake and war.’ They’re used for the creation of new varieties - such as wheat or lentils resistant to drought or disease, without pesticides. The gene bank is a public good - anyone, anywhere, can request seeds free of charge. Laaziza Atmani, head of the Al Amal women’s farming co-operative in the middle Atlas Mountains, uses ICARDA seeds and expertise to develop her couscous business. ‘Setting up the co-op changed our lives,’ she says.
