Crossing Continents

Chloe Hadjimatheou tells the astonishing story of a group of young men from Raqqa in Syria who chose to resist the so-called Islamic State, which occupied their city in 2014 and made it the capital of their "Caliphate". These extraordinary activists have risked everything to oppose IS; several have been killed, or had family members murdered. IS has put a bounty on the resistance leaders' heads. But the group continues its work, under the banner 'Raqqa Is Being Slaughtered Silently'. Chloe meets the group's founders, some of whom are now organising activists in Raqqa from the relative safety of other countries.

Dave Edmonds travels to the mid-western city of St Louis (location for the musical 'Meet Me In St Louis', starring Judy Garland) for the US chess championships. The city has become a world centre for the game of chess. Its status has partly been achieved by funding from a controversial multi-millionaire, whose childhood included time in an orphanage. Rex Sinquefield is well known for his fascination with the game and his enthusiasm is shared by many others. There is a thriving chess centre, elite tournaments which attract some of the top players, a Chess Hall of Fame and chess lessons in local schools.St Louis is one of America's most violent cities and has most recently been in the news for race riots which erupted when an unarmed black man was shot by police. Can the game of chess serve to lessen racial tension and unite its citizens across the board?Producer: Mark Savage.

Now that China has ended its One Child policy, one group of state employees may soon be out of a job - the country's hated population police. Hundreds of thousands of officers used to hunt down families suspected of violating the country's draconian rules on child bearing, handing out crippling fines, confiscating property and sometimes forcing women to have abortions. But with an eye on improving child welfare in the countryside, there is a plan to redeploy many of these officers as child development specialists. Lucy Ash visits a pilot project in Shaanxi Province training former enforcers to offer advice and support to rural grandparents who are left rearing children while the parents migrate to jobs in the big cities. If successful, the scheme could be rolled out nationwide to redeploy an army of family planning workers and transform the life prospects of millions of rural children.

Nkem Ifejika cant speak the language of his forefathers. Nkem is British of Nigerian descent and comes from one of Nigeria's biggest ethnic groups the Igbo. He's one of the millions of Nigerians, who live in the diaspora - almost two hundred thousand of them living here in Britain. Nkem wants to know why he was never taught Igbo as a child and why the United Nations Educational Scientific and Cultural Organisation, UNESCO, has warned that Igbo faces extinction in the next fifty years. In this week's Crossing Continents, Nkem travels to the Igbo heartland in the southeast of Nigeria to explore the demise of a once proud language. He discovers that recent history has had profound effects on Igbo culture and identity. He discovers too that some Igbos are seeking to reassert their language and culture. Part of this is a resurgence of Igbo identity under a new 'Biafran' movement. Is this likely to find traction or will it ignite painful divisions from the past and lead to renewed tensions across Nigeria. From Nkem's own London-based family - where his wife is teaching both him and their son to speak Igbo - to the ancestral villages of Anambra State, 'Forgetting Igbo' reveals shifting perspectives on Nigeria's colonial past, emerging new ambitions for its future - and deep fault lines at the heart of its society.Produced by Michael Gallagher.

Norway's widely regarded as one of the world's most progressive societies, yet it's at the centre of an international storm over its child protection policies. Campaigners accuse its social workers of removing children - some from immigrant backgrounds - from their parents without justification, and permanently erasing family bonds. Tim Whewell meets parents who say they've lost their children because of misunderstood remarks or "insufficient eye contact" - and Norwegian professionals who call the system monstrous and dysfunctional. Is a service designed to put children first now out of control?

In 1994 apartheid ended in South Africa and Nelson Mandela was elected president. He promised in his inauguration speech to "build a society in which all South Africans will be able to walk tall, without any fear in their hearts ... a rainbow nation at peace with itself and the world." These promises were enshrined in South Africa's post-apartheid constitution, the first in the world to outlaw all forms of discrimination. In 1994 Motshidisi Pascalina Melamu was born, making her one of the first of the so-called 'born free generation'. Pasca, as she was known, dreamed of becoming a politician, and studied hard at school. She loved singing, dancing and football. And girls - Pasca was a lesbian.In December last year, Pasca's body was found in a field. She had been beaten and mutilated. She was one of three LGBTI (lesbian, gay, bisexual, transgender or intersex) people murdered in a six-week period last year. Hate crimes against the LGBTI community have long been a problem in South Africa, and the government has tried to tackle them. But activists say these recent crimes are just one sign that things aren't getting better. James Fletcher travels to the townships south of Johannesburg to speak with Pasca's family and friends, and to ask whether the government is failing LGBTI South Africans.

An unholy spat is stirring the Sangha, Thailand's top Buddhist authority - who will become the next Supreme Patriarch, Thailand's most senior monk? Meanwhile, allegations of 'cheque-book Buddhism', cronyism and corruption abound - including allegations about tax-evasion on an imported vintage Mercedes car. In Thailand, where the majority of the population profess Buddhism, seeking ordination isn't unusual. But salacious stories about monks who commit serious crimes - everything from sex offences to wildlife trafficking - continue to shock. Watching quietly from the side-lines is the Venerable Dhammananda - female, and a Buddhist monk since 2003. Although the Sangha bars women from ordination, there are now around 100 bhikkhunis, as female monastics are known, in Thailand. And their growing acceptance by some Buddhist believers might partly be explained by a widespread disillusionment with the behaviour of some male monks. For Crossing Continents, Linda Pressly explores the rifts and sexual politics challenging Thai Buddhism and its devotees.

Lucy Ash asks why thousands of angry Romanian shepherds recently stormed the parliament in Bucharest. Sparked by an amendment to Romania's hunting law, the unprecedented protest was over plans to limit numbers of sheepdogs and restrict grazing rights. The increasing size of flocks is leading to growing conflict with both hunters and conservationists over land use. Romania has an influential hunting lobby - around two thirds of MPs are hunters - and they accuse shepherds dogs of scaring off or sometimes even killing their quarry. They also claim overgrazing is damaging the natural habitat of the deer, the boar and other wild animals they hunt. Environmental campaigners are concerned that winter grazing by ever larger flocks is having a catastrophic effect on biodiversity. At heart this is an argument about what the countryside is for. Is its main purpose an economic one? Is it primarily for leisure? Or should it be about the people who live there? Shepherds insist the law is an attack on centuries of sheep-rearing and their culture and traditions.

After the terror attacks in Paris, the world's attention turned to an inner-city district of the Belgian capital, Brussels, where several of the attackers came from. Molenbeek has been notorious for many years as a breeding-ground for Islamist extremism - and the Belgian government vowed to "clean it up". But do the authorities really have any plan to prevent the radicalisation of young Belgians? Tim Whewell has been travelling back and forth to Brussels since the Paris attacks to talk to local people as they hold up a mirror to themselves and search for explanations - and attempt to have a dialogue with a sometimes dysfunctional state.

Brazil is in crisis. Confronted with a massive downturn in the economy, its currency has crashed, while its political class sinks in a quagmire of corruption allegations linked to the state oil company, Petrobras. In the northern state of Maranhao - dominated for decades by the powerful Sarney family - a new governor from the Communist Party of Brazil is attempting to bring a fresh broom to one of the country's most undeveloped states. Already he claims to have cut expenses by millions of Reals just by removing seafood and champagne from state banquet menus. But the malaise runs deep in Maranhao. In the small community of Bom Jardim, a 25-year-old mayor is under house arrest accused of skimming the education budget and running council business remotely using WhatsApp. And with the cancelling of a project to build a huge Petrobras refinery, Maranhao is feeling the economic pressure. Linda Pressly reports from one of Brazil's least known regions.
