Follow the journey of the mighty Zambezi - Africa's wildest river.

It floods across endless plains, fuelling the migration of 30,000 wildebeest, turning villages into islands accessible only by boat. It plunges over cliffs, creating the largest curtain of water on Earth - Victoria falls. It swells up to form great rapids, a challenge for elephants to cross, and it carves out deep, treacherous gorges where the mysterious Zambezi Wave offers the ultimate surfing experience.

Zambezi spreads out to fill one of the greatest man-made lakes on Earth, home to giant crocodiles and the iconic African fish eagle, and it flows through 'lost worlds', some of the best places to see African wildlife, where unusual 'wild guests' check in at a safari lodge.

Finally, as it nears the Indian Ocean, the vast Zambezi delta gives local scientists a sign of hope for the future - a glimpse of the legendary herds of elephant and buffalo that once roamed here before the devastation of civil war.

Deeply moving and laugh-out-loud funny, Mission: Joy gives unprecedented access to the friendship between His Holiness the Dalai Lama and the late Archbishop Tutu. The self-described ‘mischievous brothers’ were filmed over five days by an award-winning team who captured a relationship built on truth, honesty and, most importantly, joy.

The film goes behind the scenes at the Dalai Lama’s residence in Dharamsala, where Archbishop Tutu and the Dalai Lama recount stories from their lives, both having lived through periods of incredible difficulty.

With genuine affection, mutual respect and a healthy dose of teasing, the two friends impart lessons gleaned from experience, ancient traditions and cutting-edge science to show that it is possible to live with joy in the face of all of life’s challenges, from the extraordinary to the mundane. Mission: Joy is an antidote for our times.

The confectionery, given to all soldiers during the conflict, was discovered in a stately home.

Jahawi is an underwater camera operator who is passionate about preserving the coastline of Kenya, his home country. The ocean is home to a whole host of marine wildlife, but one species here is particularly under threat: dolphins. This fun and curious mammal is facing a number of issues, as their habitat is being destroyed and the fish they eat are being depleted.

There is also significant human activity on this coastline, which is damaging the marine life. However, Lamu has stood the test of time and is a marine sanctuary for them, with a new port being built and things about to change. Working with the Kenyan Marine Mammal Network, Jahawi is hoping to get the area protected as a marine reserve before it’s too late.

It doesn’t take long for Jahawi to find the resident bottle-nosed dolphins as they enjoy swimming at the bow of the boat, and he soon gets into the water with the dolphins to get a closer look at these magnificent creatures. One species of dolphin he is hoping to find and film is the rare humpback dolphin.

New Generation Thinker Louisa Egbunike from Manchester Metropolitan University considers images of war and ghosts of the past. News reports of the Biafran war (1967-1970), with their depictions of starving children, created images of Africa which have become imprinted. Biafra endured a campaign of heavy shelling, creating a constant stream of refugees out of fallen areas as territory was lost to Nigeria.

Within Igbo culture specific rites and rituals need to be performed when a person dies. To die and be buried 'abroad', away from one's ancestral home or to not be buried properly, impedes the transition to the realm of the ancestors. Louisa Egbunike explores the legacy of the Biafran war and considers the image of those spirits unable to journey to the next realm, and left to roam the earth.

In the second part of her two-part journey through West Africa which began in Mali, Celeste Hicks crosses the border to Burkina Faso. Whereas the crisis of the last year and take-over of northern Mali by radical Islamists has forced ordinary Muslims there to examine their faith and the role of Islam in the rebuilding of their society, Burkina Faso has a reputation and a tradition similar to that of Mali pre-crisis – a moderate Islam where respect between Muslims and the country’s 40% Christian population is paramount; a country where animist practises survive alongside Christianity and Islam. And a country which has watched the social strife and political crisis in its neighbour and is praying that it can escape such turmoil.

Celeste visits the street brewers making the sweet millet beer in the shadow of one of the country’s mud mosques, and then she explores the animist traditions which have survived the introduction of Islam and Christianity and now prosper alongside the two main religions and she finds that some even worship both.

Celeste then takes a trip to meet the huge catfish considered so sacred they are given a human burial when they die, with help from the local blacksmith.

It is one year now since a coup in Mali which plunged the country into an almost unimaginable crisis, and led to the north of the country being over-run by radical Islamist groups intent on enforcing strict sharia law. When these groups threatened to storm the capital Bamako, the French army intervened, sending troops to chase them out of the three main towns in the north. But the horror of the last year has had a deep impact on the spiritual and community life of Malians, who until the crisis described themselves as moderate Muslims with a tradition of tolerant and pluralistic Islam.

In the first of two programmes from West Africa, Celeste Hicks reports on how Malians are struggling to understand what has happened to the north of their country, and how they’re also asking themselves deep questions about who they are and what will happen to the ‘Malian Islam’ that has shaped their country.

As the capital prays in the vast Mosques, she finds out how traditional worship fits in with this particular strain of Islam and how the culture of this vibrant country which has produced internationally famous singing stars also came under threat from the Islamists looking to redefine what the faith means in Mali.

This week Sue Lawley's castaway is judge Albie Sachs. The Jail Diary of Albie Sachs, his account of being placed in solitary confinement by the South African authorities, highlighted the dangers of campaigning against apartheid in the 1960s. After a long exile in Britain, Albie Sachs returned to his homeland in the 1990s to help shape its new constitution and become one of its most senior judges.
