Crossing Continents

Growing numbers of tourists are travelling to the Peruvian Amazon to drink ayahuasca, a traditional plant medicine said to bring about a higher state of consciousness. Foreigners come looking for spiritual enlightenment or help with mental health problems like trauma, depression, and addiction. But not everyone is happy about Peru’s booming ayahuasca tourism industry. A group of indigenous healers are fighting back against what they see as the exploitation and appropriation of their cultural heritage by foreigners - who run most of the ayahuasca retreats popular with tourists. This coming together of cultures has thrown up another serious problem too: vulnerable women being sexually abused while under the influence of charismatic healers and this powerful psychedelic.

Ninety year old Galina is one of the last witnesses to the wild natural world that preceded the Chernobyl zone in southern Belarus. 'We lived with wolves' she says 'and moose, and elk and wild boars.' Soviet development destroyed that ecosystem. Forests and marshland were tamed and laid to farmland and industrial use. But when the Chernobyl reactor exploded in 1986, the human population was evacuated; their villages were buried beneath the earth as though they had never existed. A generation on, it seems that the animals Galina knew are returning. But how are they are affected by their radioactive environment? And what can we infer about the state of the land? Monica Whitlock visits the strange new wilderness emerging in the heart of Europe. Produced and Presented by Monica Whitlock Editor, Bridget Harney

Fatmata, Jamilatu and Alimamy all see themselves as failures. They’re young Sierra Leoneans who risked everything for the sake of a better life in Europe. Along the way, they were imprisoned and enslaved. They saw friends die. Eventually, they gave up. Now, they’re home again - facing the devastating consequences of what they did to their families before they left, actions that have left them ostracised by their nearest and dearest. Who will help them to survive back home? Can they rebuild their lives, and achieve any reconciliation with their parents? And if they can’t, will they be tempted to set off again, to seek their fortunes abroad? Produced and presented by Tim Whewell Editor, Bridget Harney

Iceland's glaciers are melting at an unprecedented rate, with scientists predicting that they could all be gone 200 years from now. How is this affecting the lives of local people, and the identity of a nation that has ice in its name? Maria Margaronis talks to Icelandic farmers and fishermen, scientists and environmental activists about their (sometimes surprising) responses to climate change, and asks why it’s so difficult even for those who see its effects from their windows every day to take in what it means.

How do you achieve net-zero carbon emissions in just fifteen years? In Finland, a fisherman-turned-climate scientist believes he has part of the answer: re-wilding the country’s peat fields. Gabriel Gatehouse travels to the country's frozen north to meet Tero Mustonen, as he battles lobbyists and vested interests in government and the peat industry, in a race to mitigate the consequences of climate change.
