A bonus episode from HARDtalk, in-depth, hard-hitting interviews with newsworthy personalities.

For a period earlier this month, the historic city of Chiang Mai in northern Thailand had the worst air of any city in the world.

The city gained the same unwanted accolade last year. The practice of agricultural burning in the hills around Chiang Mai renders the air so toxic from February to April that it becomes unsafe to breathe. Respiratory problems and allergies caused by PM2.5, a type of pollution, led to more than 12,000 people being admitted to hospital in 2023.

The bad air affects everyone, including the young and physically fit. In December 2023, Krittai Tanasombatkul, a 29-year-old doctor and basketball fanatic, succumbed to lung cancer. Like 40% of people with the disease in the city, he was not a smoker.

Victoria Uwonkunda makes an emotional journey back to Rwanda, where she grew up. It is the first time she has visited since the age of 12, when she fled the 1994 genocide with her family. Victoria retraces her journey to safety out of the capital Kigali, to the border with the Democratic Republic of Congo. Along the way she speaks to survivors of the violence – both victims and perpetrators - to find out how the country is healing, through reconciliation and forgiveness. Victoria meets Evariste and Narcisse, who work together on a reconciliation project called Cows for Peace. Evariste killed Narcisse’s mother during the 1994 genocide. And she meets Claudette, who suffered unimaginable horrors at the hands of a man, Jean Claude, sitting next to her as she tells her story.

Michael Volle is a baritone singer who has made his name with magisterial operatic performances, particularly Wagner. Helmut Deutsch has been playing the piano alongside the great and the good of the classical world for five decades, including the soprano Ileana Cotrubas and the tenor Jonas Kaufmann. Performing the 24-song cycle that Franz Schubert wrote at the end of his short life, Die Winterreise, or the Winter’s Journey, is considered the pinnacle of the recital repertoire, even for such accomplished musicians. The trust between singer and pianist must be absolute, because the two performers are, in Volle’s words, “naked and pure on stage”. Deutsch and Volle have a 20-year friendship and working partnership to build on, a musical connection that brings them together to perform this “summit” of singing over and over again. Yet their next performance will be something out of the ordinary. They are undertaking a staged performance at the Gran Teatre del Liceu, in Barcelona. The musicians will be joined by actresses on the stage, photographs accompanying the music, and newly developed poems interspersed between songs. How will the staging affect the relationship between singer and pianist, and how will it impact the music? Writer and journalist Lluís Amiguet joins rehearsals in Barcelona to find out.

Bjarke Ingels is the Danish architect who is responsible for creating the flood defence project for Manhattan. In 2012 Hurricane Sandy saw flood water rise up to 2.4 metres. Lives were lost, the city’s transportation system was brought to a stand-still and the New York Stock exchange was closed for two days. As a child, Bjarke wanted to draw comic books and walk on roofs and the buildings that he’s designed include a power station with a ski slope. How can he build his sense of fun and creativity into vital protection against climate change?

Long lines of tractors have become an increasingly common site in recent months on the streets of many European cities. In Poland, farmers blocked roads this week in protest at rising costs and competition from cheaper imports from Ukraine. Farmers have also been protesting in the UK, Hungary, Belgium, Spain, Greece and Italy on a range of issues from fuel prices to new environment rules. To understand the challenges farmers are facing – but also get an insight into their lives, we speak to farmers in the UK, France and an aspiring farmer in Germany who share their experiences. We also bring together three farmers in India. With a forthcoming national election, thousands recently marched – once again – on the capital Delhi. They tell us why they farm and share with us their emotional connection to the land.

Next Year will mark 50 years since the start of a seven-year violent military dictatorship in Argentina. During this period, many who opposed the fascist regime were detained, kidnapped, tortured – and in some cases they disappeared never to be seen again. The Catholic church has always been very powerful in Argentina, and closely linked to the state. While some in the church were victims themselves, the hierarchy of the Church has been accused of playing a role in the dictatorship. At best, it has faced allegations of knowing what was going on and not doing enough to stop it. At worst, it has faced allegations of being actively complicit in some of the abuse the military was perpetrating. A group of mothers and grandmothers during this period set up a campaign to try and find their missing children. The ‘Madres’ and ‘Abuelas’ of Plaza de Mayo movement started on a pilgrimage in 1977, where the women wore the white cloth of their missing children’s diapers on their heads to identify themselves. Today, many of them are still looking for their children, and still identifiable by the white headscarves they wear to campaign each week. In this episode of Heart and Soul, the BBC’s Ione Wells and Jessica Cruz travel to Argentina to speak to some of the victims of the dictatorship. These include people who were kidnapped, detained and in some cases tortured themselves – sometimes in the presence of Church officials. And one of the ‘Madres’, aged 93, who still hopes to find her missing son before she dies. How did this affect their relationship with the Church? And how did witnessing atrocities like this impact their faith? Presenter: Ione Wells Producer: Jessica Cruz / Ione Wells Researcher: Emma Smith Series Producer: Rajeev Gupta

Thousands of people every day are on the move across Mexico towards the border with the US. But for migrants, this is one of the most perilous journeys in the world: land routes are dominated by powerful drug cartels and organised crime groups.

In this episode of Border Stories, Linda Pressly hears terrifying stories of kidnap and extortion from those who have risked everything to enter the United States.

The US/Mexico border has become the most important battleground for Americans in this year’s presidential election, but it seems no one can stop the men with guns who operate with impunity south of the border in Mexico.
