Since December, gangs have seized more than a thousand students and members of staff from schools in armed raids across northern Nigeria. The wave of abductions is having devastating consequences for the country, which already has the highest number of children out of education anywhere in the world. Parents face extortionate financial demands in exchange for the freedom of their sons and daughters, and many families in Africa’s most populous nation are now too afraid to send their children to class. Some have decided to flee rural areas for the relative security of cities, adding to demographic pressures and threatening food supplies as crops go untended. For Assignment, the BBC’s Mayeni Jones travels across north-western Nigeria, meeting those who have been affected by the crisis in order to understand why it has arisen – and what the authorities can do to stop it.

As you enter Lungelo Gumede’s studio, in the heart of South Africa's coastal city of Durban, you are greeted by the smell of paint, clay and other materials. Across the room, what you see is surprising. At first glance, you are looking at Nelson Mandela, the recently departed King of the Zulu Nation, Goodwill Zwelithini and Queen Elizabeth II. As you get closer, of course, you discover they are wax figures elegantly dressed in real clothes. That's what Lungelo specialises in - life size statues of prominent global figures in politics, sports and entertainment, with a special focus on African heroes. His art is celebrated across South Africa and, at only 36, he’s on a mission to create the country’s first ever wax museum. Mpho Lakaje spends a week with Lungelo to discover what it takes to make a new wax figure.

Kenneth Kaunda, the first President of Zambia was a unique African leader. He led the African continent’s fight against Apartheid, gaining a peaceful transition to power in his own country. He was influenced by reading Mahatma Gandhi yet ruled with ‘an iron fist in a velvet glove’. He loved to sing and play guitar, particularly to his wife of many years Betty and in his 27 years as president. In the end he was voted out of office but left with dignity when he admitted defeat in a multi-party election. Audrey Brown charts the rise and fall of former Zambian President Kenneth Kaunda.

Amanda Khozi Mukwashi is the chief executive of Christian Aid, leading development and humanitarian work in Africa, Asia and the Middle East, Latin America and the Caribbean.

Amanda was born in Twickenham and grew up in Zambia and Rome where her stepfather worked in the diplomatic service. She studied international trade and investment law at the University of Zambia in Lusaka and during this time she began to develop her political outlook and commitment to the issue of social justice.

She moved to the UK in 1996 where she took a master’s degree at the University of Warwick. But even with two degrees and considerable work experience she was unable to find a job and retrained as a care worker. She says her time working in nursing homes “reshaped” and “humbled” her.

Later she worked for the VSO and served with the United Nations Volunteer programme in Germany before landing what she calls her “dream job” at Christian Aid in 2018.

British-Nigerian poet and activist Femi Nylander travels to West Africa to discover the modern-day impact on its people of atrocities that took place over a century ago.

Femi traces the footsteps of a French army officer, Paul Voulet, who forged a path of unspeakable barbarity across the West African state of Niger.

Voulet’s actions closely mirror the colonial horror depicted in Joseph Conrad’s celebrated novel Heart Of Darkness, which was written at the very same time that Voulet unleashed his killing spree in 1899.

In Niger, with words and images from Conrad’s time still echoing in his mind, Femi finds painful memories and communities still living with the traumatic consequences of the violence of a century ago. But amidst this terrible history, Femi also encounters beauty and a spirit of hope: young people working together and a country determined to find its way out of the horror by harnessing the power of its most precious resource - the light of the sun.

Tony Kofi is the fifth of seven brothers and was raised by his Ghanaian parents in Nottingham in the late 1960s.

At secondary school Tony was turned down for the music course he wanted to do, told he wasn’t focused enough, and directed to do woodwork instead. He stuck with woodwork as he was really good at it, and left school at the age of 16 to become a carpentry apprentice. A few months in, working on a house construction, he fell from the roof arch to the ground floor where he landed on his head. Tony says he experienced the fall in slow motion and he had clear visions of unknown faces and places and saw images of himself playing an instrument. During his recovery it was that image which kept coming back to him. Tony made the decision to quit his apprenticeship and announced his intention to become a musician. He bought a saxophone and taught himself how to play by ear, before earning a full scholarship to the prestigious Berklee College of Music in the US.

Scroll forward many years, Tony is now a highly-acclaimed jazz saxophonist and credits the fall with turning his whole life around.

Despite being home to our early ancestors, attempts to find evidence of early burials in Africa have proved unsuccessful. That is until now. Professor María Martinón-Torres explains how findings from a 78,000-year-old Kenyan grave shed light on how our ancestors related to the dead.

In keeping with the theme of clues from the past, Cardiff University academics have been studying the remains of crew who drowned on King Henry VIII’s favourite ship, the Mary Rose. As it turns out, Tudor England was more ethnically diverse than we previously thought.

During the 1980s and 1990s, DJ Andy Kershaw travelled around Africa and the Americas searching out great music and taping it on his Walkman Pro, a new broadcast-quality cassette recorder that was bringing about a revolution in mobile recording. He also used it to capture his celebrated Kitchen Sessions, held in his small flat in Crouch End.

In this episode, Andy meets Kenyan harpist Ayub Ogada on a beach in Cornwall, the Antioch Gospel group in a car park in New Orleans, Cuarteto Iglesias on a roof top in Cuba and a young Ballake Sissoko next to the railway tracks in Bamako, Mali. On his very first day recording with his Walkman Pro, Andy visits the Edale Bluegrass Festival then travels to Leeds to record a rare performance from guitarist Mark Knopfler in a pub with his early group The Duolian String Pickers. Back in Andy’s kitchen Louisiana comes to Crouch End with sessions from blues man Lazy Lester and Cajun stars DL Menard, Eddie LeJeune and Ken Smith. Plus we pay another visit to Wilkinson's HiFi in Nelson to find out just why the compact cassette format is so enduring and well loved.

The First Congress of Black Writers and Artists in Paris 1956 staged debates about colonial history which are still playing out in the protests of the Gilets Noirs. New Generation Thinker Alexandra Reza leafs through the pages of the journal Présence Africaine, and picks out a short story by Ousmane Sembène tracing the dreams of a young woman from Senegal. Her experiences are echoed in a new experimental patchwork of writing by Nathalie Quintane called Les enfants vont bien. And what links all of these examples is the idea of papers, cahiers and identity documents.
