Controlling nature's data

Luke Jerram creates spectacular art installations all over the world. He reached millions of people with his work Play Me, I’m Yours, inviting anyone to make music on the 2,000 pianos he had placed on the streets of more than 70 cities. He has also created large sculptures of the moon, the planet Mars and the sun, which were suspended in spaces like cathedrals so that visitors could admire the celestial bodies up close. Julian May follows the creation of the Jerram's latest work, made for Bradford, this year’s UK City of Culture. A Good Yarn plays on the double meaning of the word “yarn” – both a length of thread and a story. It looks like a giant multi-coloured ball of wool, three metres high, which will be rolled through the city’s streets. Luke Jerram collaborates with Bradford residents to create a kilometre-long rope, made from woollen fabric donated by the public or from second-hand shops.

Puerto Casado is a remote village in Paraguay, in South America. It’s not dissimilar to many other rural towns in the area: red-brick houses, small grocery stores and unpaved roads. But what makes Puerto Casado an exception is that it’s at the centre of a land dispute between the Paraguayan state, local residents and the Unification Church, a controversial religious group from South Korea. Ronald Avila-Claudio from BBC Mundo has recently been there.

Israel faces growing international isolation over the shocking images of starvation in Gaza. Although Israel says there are no restrictions on aid deliveries – which it co-ordinates – or any starvation, charities warn the aid being allowed in is only a fraction of what is needed.

Bergen-Belsen Concentration Camp in Germany was the only camp liberated by the British Forces in April, 1945. Prior to that, over 50,000 people were murdered there. After liberation, the British Forces, alongside the American Jewish Joint Distribution Committee (AJDC) set up another camp about 2km away, the Bergen-Belsen Displaced Persons (DP) Camp, the largest DP camp in Europe, where over 2,000 babies were born. Known as ‘Bergen-Belsen Babies’, Susan Schwartz and Karen Lasky were two of the many born there and still hold the label ‘stateless’ after their families were eventually accepted and immigrated to Canada. On the 80th anniversary of the liberation, survivors and Bergen-Belsen Babies gather for the week, trying to fill in the gaps of what happened to their families and reflect on their childhoods.

The JNIM branch of al-Qaeda is one of the world's deadliest jihadist groups. It has firmly planted its flag in the Sahel. Sub-Saharan Africa has emerged as a key battlefront for jihadists: around 50 percent of deaths from terrorism in 2024 were registered in the Sahel region alone, according to the Global Terrorism Index. JNIM is an eclectic yet united coalition, rooted in the tribal desert regions of Mali, Niger, and Burkina Faso. We look into its leaders, its narrative, and its modus operandi, and analyse the complexity of a region beleaguered by military coups, ethnic violence, and climate change.Contributors: Barry Marston, Jacob Boswall Producer: Kriszta Satori, Elchin Suleymanov Presenter: Krassi Ivanova Twigg

Until this year Greenland rarely made the international news and probably only the islanders themselves took much time to contemplate their future. But then US President Donald Trump said he wanted to annexe it for its strategic position and mineral wealth. So the question has become a lot more pressing. With a population of just over 55,000, the biggest island in the world has its own parliament, but foreign policy is controlled by Denmark, something many residents are unhappy about.Denmark subsidises Greenland to the tune of around $10 000 per person per year. On an island where fishing is the primary source of income, independence would mean either increasing tourism or allowing the mining of minerals like rare earth metals. However the islanders have always favoured strict environmental controls when it comes to mining and it’s expensive for tourists. Hedi Nermin Aziz travels from Denmark to Greenland and talks to politicians, musicians and influencers about Greenland’s Innuit identity and to find out if it can and should go it alone.This episode of The Documentary comes to you from Assignment, investigations and journeys into the heart of global events.
