At the end of America’s southern border wall with Mexico, James Naughtie meets the people helping recently-arrived migrants survive in the extreme conditions. Beginning his day's journey at a church in Tucson, Arizona, James hears how members of the congregation support a programme helping migrants find work. And at the end of the border wall with Mexico, he meets recently-arrived migrants from around the world seeking asylum in the United States. He watches them being collected by Border Patrol for processing, and speaks to the humanitarian workers about what might happen to their claims for asylum.

Born in 1924 in Harlem, New York, James Baldwin's novels, essays and speeches articulated the racial oppression facing African-Americans. In works like Notes on a Native Son and The Fire Next Time, Baldwin expressed how colour is not a human or personal reality, but a political one. In Giovanni’s Room, a frank portrayal of a gay relationship, he draws on his own life as a gay man. In the wake of Black Lives Matter, the US continues to grapple with tension and division, with race and identity still huge cultural and social issues. Cianna Greaves looks at how Baldwin’s life and works still matter and inspire artists today, including Detroit based artist Sabrina Nelson whose exhibition Frontline Prophet: James Baldwin has travelled across the US; curator Ashara Ekundayo; poet and founder The Baldwin Institute, Achille Tekiang; writer and executive director of La Maison Baldwin, Tara Phillips; as well as French journalist, film-maker and graphic novelist Rokhaya Diallo.

A bonus episode from The Conflict.

Jonny Dymond brings together a carefully assembled panel of experts, academics and journalists to talk about the conflict in the region. They assess what has happened in history to lead us to this point. And, look at what history can teach us about what might happen next.

The Taliban edict that women's voices should not be heard aloud renders women up and down Afghanistan inaudible as well as invisible in public. Women are already denied most forms of education and employment. They are not allowed to go outside without a male guardian, and have to be completely covered up, including their faces. Now the new rules say they should be quiet too. Women singing together, or even raising their voices in prayer, is forbidden.

But there's more than one way to be heard.

Our Whole Life is a Secret records the day to day life of 'Leila', a lively, energetic Afghan woman aged 23, doing everything she can to navigate the rules. From behind the walls of her home, Leila reveals her vivid interior world, and that of her female friends and relatives. She and her sisters are the first women in their family to read and write, and before the Taliban returned to power in 2021, she was a university student. Now she teaches in a secret school and is part of a dynamic online learning community. From reading Emily Bronte to working out to Zumba, Leila is determined to keep stay sane and busy.

'Leila' is not her real name and all locations are omitted for safety reasons. Her words are read by Asal Latifi.

Legendary musician, composer and producer Brian Eno has turned his attention to the climate crisis. In 2021 he founded the ground-breaking organisation EarthPercent, a charity which aims to raise $100m by 2030. The money - from royalties of partner artists - is being used to reduce the environmental impact of the music industry, as well as restoring nature, advancing policy change and securing "climate justice and fair environmental stewardship." Among the musicians with whom he is currently collaborating are Coldplay, CHVRCHES, Nile Rogers, Anna Calvi, Louis VI and Michael Stipe. A rare honour, listeners are welcomed inside the hallowed soundproofed walls of his London studio, where they experience first-hand the recording methods of his latest project.

Ghislaine Boddington aspires to be interconnected with an AI digital companion that advises and supports her, keeps her healthy and represents her around the world. A twin that could live on after her death, or for as long as someone pays the subscription. In practical terms, a digital bio-twin is made up of continuously measured multiple biological signals from your body. These might include your heartbeat, breath, temperature and muscle tension, as well as food intake, exercise and mental health - all fed into an avatar body. By combining AI and, for example, scanning our bodies and faces, cloning our voice and mannerisms, our virtual twin will become more and more like us. In a journey that involves an MRI heart scan, dancing in a Belgium basement and a discussion about digital death, Ghislaine learns how to build her own digital twin.

After publicly criticising the Ashanti King, Otumfuo Nana Osei Tutu II, journalist Afia Pokua had to apologise following a strict traditional protocol. BBC Africa's Daniel Dadzie explains how royal apologies work in Ghana, and why Afia didn't get a pardon.

Imagine waking up in the morning and going outside to discover that the air is so toxic that it makes your eyes water and can make it hard to breathe. This is happening to millions of people in South Asia right now, especially across Lahore in Pakistan and Delhi in India, and it is due to a thick smog that can be seen from space. Residents in both cities discuss the difficulties of trying to go about everyday life while negotiating lockdowns and also trying to get food and continuing to work. Host Mark Lowen also hears from three students aged 13-22 about the impact on their education, as well as their mental and physical health.

Father Michel was brought up in a devout family in a devout country. He witnessed the horrors of the Second Congo War but when he was sent to France he was nevertheless shocked to find so much material and spiritual poverty there. His first posting as a missionary was working with young people separated from the parents because of violence, addiction, abuse. Now he has a parish in Alsace, or rather 12 parishes. He tells us about the joys and pains of being an African missionary in Europe. We hear too about his experience of rejection because of his ethnic background. But above all the warm welcome he has received from active Catholics who have become dependent on these “missionaries-in-reverse” from Africa for the practice of their faith.
