Monty Don continues his extraordinary journey in the Mediterranean - the cradle of European civilization.

In Italy, Monty visits some of the elaborate high Renaissance gardens of stone and water which have hugely influenced western garden design. He also visits the remains of Emperor Hadrian's palatial retreat.

Monty then looks at the artistic achievements of the Moorish culture. He travels to Marrakesh, where he visits The Aguedal - one of the oldest continuously maintained gardens in the world; and in Spain he visits The Alhambra, thought by many to be the most perfect garden in the world.

Travel documentary. Simon Reeve travels the Tropic of Capricorn, the line of latitude that cuts across South Africa, South America and Australia. Simon is distraught when he witnesses the Zimbabwean refugee crisis. He watches giant rats clear land mines in Mozambique and eats soup made from the penis of the Xebu. He visits a shanty town where thousands of impoverished Madagascans are digging for sapphires.

Following the success of Equator, Simon Reeve embarks on a journey along the tropic of Capricorn, the line of latitude which cuts through Southern Africa, Australia and South America. During his epic journey around the world, he uncovers extraordinary stories from the southern hemisphere.

The first leg sees Simon crossing the beautiful landscapes of Namibia and Botswana. He has a close encounter with hungry cheetahs and visits the world's largest diamond mine. He crosses the Kalahari Desert in search of the famous Bushmen, who claim they have been evicted from their ancient homelands.

Melvyn Bragg and guests discuss the Algerian-French writer and Existentialist philosopher Albert Camus. Shortly after the new year of 1960, a powerful sports car crashed in the French town of Villeblevin in Burgundy, killing two of its occupants. One was the publisher Michel Gallimard; the other was the writer Albert Camus. In Camus’ pocket was an unused train ticket and in the boot of the car his unfinished autobiography The First Man. Camus was 46. Born in Algeria in 1913, Camus became a working class hero and icon of the French Resistance. His friendship with Sartre has been well documented, as has their falling out; and although Camus has been dubbed both an Absurdist and Existentialist philosopher, he denied he was even a philosopher at all, preferring to think of himself as a writer who expressed the realities of human existence. Awarded the Nobel Prize for Literature in 1957, Camus’ legacy is a rich one, as an author of plays, novels and essays, and as a political thinker who desperately sought a peaceful solution to the War for Independence in his native Algeria. With Peter Dunwoodie, Professor of French Literature at Goldsmiths, University of London; David Walker, Professor of French at the University of Sheffield; Christina Howells, Professor of French at Wadham College, University of Oxford.

In a Top Gear special, Jeremy, Richard and James face one of their greatest challenges as all three are sent to Africa and each told to buy a second hand car costing no more than £1500. It must not be a 4x4 and must not be designed in any way to go off road. Which could be a problem, since their task is then to drive across the wilds of Botswana, negotiating massive salt pans, treacherous rivers and reserves full of animals, most of which will want to eat them.

Along the way they face fierce heat, suffocating dust and an encounter with the Stig's African cousin in what becomes one of Top Gear's most epic adventures.

Kirsty Young's castaway this week is Joel Joffe. For many years he was the chairman of Oxfam, before that he set up a hugely successful insurance company and most recently he's been campaigning for terminally ill people to have the right to die. But the career in which he has had the greatest impact is the one he was forced to give up more than 40 years ago - law.

In 1963, Joel Joffe was a young defence solicitor, so dismayed by the apartheid system of his native South Africa that he was on the brink of emigrating. Then he was asked to take over the defence of a group of ANC activists including Walter Sisulu, Govan Mbeki and Nelson Mandela.

The trial gripped the world and was all the more extraordinary because, far from aiming to secure his clients' freedom, Joel Joffe was simply fighting for them not to receive the death penalty. He tells Kirsty how, even in his prison clothes, Nelson Mandela was a figure of calm authority, who guided them through the trial.

David Attenborough's documentary series which celebrates our planet in all its eclectic wonder. He reveals the greatest woodlands on earth, from the evergreen forests of the frozen north to the deciduous dry forests of the equator.

The Taiga forest is a silent world of stunted conifers cloaked in snow and ice. The trees form a belt that circles the globe, broken only by ocean, and contains a third of all trees on earth. Here, animals are scarce, with just a few charismatic loners like the wolverine and lynx.

By contrast, the broadleaf forests of North America and Europe bustle with life. The most startling illustration happens just once every 17 years, when the nymphs of the periodical cicada burst from the soil in the biggest insect emergence on the planet.

In California, witness the cameras fly up the tallest trees on earth: giant redwoods over 100 metres high. See General Sherman, a giant sequoia, ten times the size of a blue whale, and the largest living thing on the planet. Close by are bristlecone pines, so old they pre-date the pyramids and were already 2,500 years old when Jesus Christ was born.

The baobab forests of Madagascar are the strangest of all. The bizarre upside down trees store water in their swollen trunks and harbour strange wildlife, such as the tiny mouse lemur, the world's smallest primate.

For almost four years, an Algerian Islamist has been under scrutiny in New Zealand. Ahmed Zaoui was initially placed in solitary confinement and is now under effective house arrest.

Sue MacGregor goes to Johannesburg to reunite a group of former political prisoners who were incarcerated on Robben Island when Nelson Mandela was there throughout the 1960s and 70s.

But it also became a place where many of the country's future leaders learnt the skills which would later bring them to power. We hear the extraordinary stories of five former prisoners.
