Joanna's adventures in and around Iran, from where she followed the Silk Road through Azerbaijan and Georgia, finally moving on to Venice. Also presents behind the scenes footage from Joanna's travels in Haiti and Cuba.
The adventurer reaches Sri Lanka, whose strategic location and tropical spices made it a target for invaders and colonisers for centuries. In the north he visits the scenes of vicious battles between the Tamil minority and the Sri Lankan army, traumatic events from which the population is still recovering. On his way to Bangladesh, he hitches a ride on a trawler, highlighting one of the Indian Ocean's fastest-growing industries - providing prawns for the West. But as he reveals, it comes at a price for the environment.
Simon's adventure starts in the magnificent 'red centre' of the continent and onwards through South Australia, via the extraordinary Indian Pacific Railway until he reaches the west coast city of Perth. On the way, he joins an Aussie rancher in the parched outback and takes part in a spectacular camel round-up. This mad adventure, involving specially adapted off-road vehicles and a chopper, is part of an ongoing effort to stop the damaging spread of up to a million feral camels across the country. Finally in Perth, Simon discovers a full scale British invasion. Working in a mine or driving a lorry can bring a salary of a hundred thousand pounds a year, as evidenced when Simon meets a former bin man from hull who is now living the dream, with a beautiful house in the sun, private pool and his very own boat.
The final leg of Ade's tour of Africa sees him travelling from the beaches of Mozambique, through South Africa, before ending his entire trip in Zimbabwe. He begins on the golden sand beaches of Mozambique's Bazaruto Archipelago, one of Africa's highlights. At Paradise Island, he finds an abandoned hotel, a visual reminder of Mozambique's recent history - this place was once a high-end tourist destination, but 25 years of colonial and then civil war put a stop to development. But the local wildlife has benefited from the fact that so few tourists now come here, and Ade is able to snorkel with one of the world's most elusive sea creatures - a dugong. Since the wars, Mozambique has struggled to develop, and Ade meets someone for whom life is especially hard – a wheelchair user like himself. In a country where disability is viewed with fear and superstition – and believed by many to be contagious – even catching a bus proves impossible for Castigo. The best thing in his life is exactly the same thing that turned Ade's life around - wheelchair basketball - and Ade can't help getting carried away in a game. Along the coast, at one of Mozambique's largest ports, Ade finds out that China is investing a huge amount in Mozambique – and elsewhere across Africa. The money often comes with strings attached, but a poor country like Mozambique needs financial help, which has to come from somewhere. Ade's next stop is South Africa. The country is famous for its wildlife but Ade hears how Chinese influence is having a dramatic impact here – the country's rhino population has been decimated by poachers, driven by a demand for rhino horn in Chinese medicine. Ade follows rangers with a surprising way of tackling the problem - by cutting off the rhino horn themselves, they hope to deter poachers. Ade travels to Johannesburg to see how the country is faring 25 years after apartheid ended. On a tour of the city, he is upset to discover that although the black population now have voting rights, they are living in an economic form of apartheid, with 25% unemployed and many squatting on whatever land they can find. In an emotional scene, Ade visits a squatted piece of land, moments after the police have destroyed people's houses, to hear claims that Mandela's legacy has been forgotten. Land reform is the big political issue here today, with many calling for a redistribution of land from rich white farmers to the black population. The final stop on Ade's African adventure is Zimbabwe – where land reform has already happened, with disastrous results. Ade finds a country still struggling economically. His first stop is the Kariba dam, and a hair-raising boat ride on the vast and stunning Lake Kariba. Ade finds that locals are worried about the stability of the Kariba dam and work has begun to stabilize undermined foundations. The worrying decay of this crucial dam is a sign of how much this country suffered under the rule of Robert Mugabe. As Ade has seen so often on his trip around Africa, Zimbabwe is a country that should be rich. It has huge quantities of gold – enough, in theory, for the entire population to be a millionaire. But there isn't the infrastructure of investment to get at it - in a country dogged by poverty and corruption. But the departure of dictator Robert Mugabe brought a new optimism, and Ade meets gold miners who are willing to risk daily exposure to toxic mercury for every scrap of gold they can get and an entrepreneur who believes the industry can be transformed. Despite the return of violence and repression in Zimbabwe, Ade ends his journey on a high, visiting a remote hut that has been turned into the set of a music video. He joins UK indie musician Shingai Shoniwa as she shoots the video for her forthcoming debut single, Coming Home, in a country that she believes is on the up, and deserves a fresh chance.
Simon Reeve sets out on an epic journey around the island of Ireland - a place steeped in history, culture and belief, but with a complex past. Part 2: North Starting at the spectacular Giant's Causeway in Northern Ireland, Simon travels down the east coast to the great and rapidly changing cities of Belfast and Dublin. He ends his journey in the stunning Wicklow Mountains.
Giles Coren and Monica Galetti experience the warm embrace of Fogo Island Inn on a rocky, sea-sprayed outpost of remote Fogo Island in Newfoundland. White, angular and perched atop zig-zagged stilts like the local fishermen's houses.
The fourth leg of the broadcaster's journey takes him from Oman to the Maldives. He starts in the Strait of Hormuz, where oil from the Gulf is shipped through the narrow channel, then moves on to Mumbai, the ocean's biggest port. In the Maldives, Simon finds arguably the most beautiful collection of tropical coral islands in the world - but the fragile underwater environment is a barometer for the changing nature of the sea, as he witnesses how bleaching has damaged the coral and one entire island has been manufactured as a landfill dump to deal with the problem of rubbish.
