Precipitous mountain roads, specially modified bikes, and deadly consequences. Simon Maybin spends time with the young men who race down the steep roads of Colombia’s second city Medellin. Marlon is 16 and he’s a gravitoso - a gravity biker. He hooks onto the back of lorries or buses climbing the precipitous roads to reach high points around the city. Then, he lets gravity do its thing and - without any safety gear - hurtles back down the roads, trying to dodge the traffic. This year, two of his friends have died gravity biking and Marlon has had a near-fatal accident. But he’s not quitting. So what drives young men like him to take their lives into their own hands? And what’s being done to stop more deaths? Produced and presented by Simon Maybin.

Marawi in the southern Philippines is a ghost town. In 2017, it was taken under siege for five months by supporters of Islamic State who wanted to establish a caliphate in the predominantly Muslim city. After a fierce and prolonged battle, the Philippine army regained control – but Marawi was left in ruins. Two years on, reconstruction has barely begun and over 100,000 people are yet to return home.

China’s New Silk Road reaches across all parts of the globe; building roads, bridges and towering cities where before there were none. In Kazakhstan, China’s neighbour to the west, this vast project has created a port. But there’s no water there, just desert… and trains running all the way from China through to Europe and the Middle East. Meeting the hundreds of shoppers and traders, it’s astonishing to think that just a few years ago this border was a closed military zone - the frontier between two giant communist states. But turn the clock back further and we discover this part of Central Asia has always been closely tied to China, in languages, culture and contested history. For Crossing Continents, Rose Kudabayeva returns to her home country Kazakhstan, to meet people living along the New Silk Road and record how their world is changing.

Everybody in Romania knows someone who has died in a road accident. The country has the highest road death rate in the European Union – twice the EU average and more than three times that in the UK. A young businessman, Stefan Mandachi, has built a metre long stretch of motorway near his home in the rural north-east of the country, as a visual protest against political inaction and corruption. For Crossing Continents, Tessa Dunlop travels to one of Romania’s poorest regions, Moldova, to meet this new champion of road safety, and the families who have paid the highest price for the country’s poor transport networks.

Who will shape the future of the hurricane-hit, tropical isle of Barbuda? In 2017, category-5 hurricane Irma devastated much of Barbuda's 'paradise' landscape, and its infrastructure. The national government – based on the larger, neighbouring island of Antigua – evacuated the population of some 1800 people. But within days, although the people weren’t allowed to return, bulldozers were clearing ancient forest to build an international airport. Critics called this another case of, 'disaster capitalism' – governments and business taking advantage of catastrophe to make a profit.

Barbuda has long been viewed as ripe for more tourism – Hollywood actor Robert De Niro is part of a commercial enterprise working on the opening of an exclusive resort. One of the obstacles to widespread development has been the island’s unique system of tenure – all land has been held in common since the emancipation of Barbuda’s slave population in the 19th century. But last year the government repealed the law guaranteeing those communal rights, partly to attract investment to the island. Meanwhile, although the hurricane season began on June 1st, families are still living in tents.

With the main opportunity to earn revenue coming from tourism, the national government is thoroughly irked by Barbudans' resistance to profit from top-dollar visitors. It argues that projects can be environmentally-friendly. But in the wake of Irma, the impact of climate change hangs heavily on Barbuda. How can this pristine island preserve its future and still develop the economy?

An icon of Italian design; a centrepiece of a community; a tragedy waiting to happen? When the Morandi bridge opened in 1967, it was one of the longest concrete bridges in the world, connecting the port of Genoa with the rest of Italy and Italy with northern Europe. Built during the post-war economic boom, it was the centrepiece of Italy’s plans to modernise its roads and was a proud symbol of the country’s engineering and architectural expertise. But all that came to a tragic end in August last year when a section of the bridge collapsed killing 43 people and leaving 600 people without a home. Helen Grady speaks to people whose lives have been touched by the bridge from the moment it was built to the moment it collapsed. And she asks how such a vital piece of infrastructure, carrying thousands of cars and lorries every day, could be allowed to fail.

A small town goes on life-support after its lone hospital closes. The story of Jamestown, Tennessee, recorded in the emotional hours and days after its 85-bed facility shut. Rural hospitals are closing across the United States, leaving patients dangerously exposed. Can Jamestown buck the trend and reopen?

When Azeteng, a young man from rural Ghana, heard stories on the radio of West African migrants dying on their way to Europe, he felt compelled to act. He took what little savings he had and bought reading glasses with a hidden camera – his “secret spectacles”. Then he put himself in the hands of people smugglers and travelled 3,000 miles on the desert migrant trail north, aiming to document the crimes of the traffickers. Along the way he saw extortion, slavery, and death in the vast stretches of the Sahara. In this edition of Crossing Continents we tell the story of his journey – a journey that thousands of young Africans like him attempt each year. Reporter, Joel Gunter.

In 2009, Mennonite women in a far-flung Bolivian colony reported mass rape. Now leaders of this insular Christian community with its roots in Europe are campaigning to free the convicted men. More than 100 women and children were attacked in the colony of Manitoba, and their courage in telling their stories secured penalties of 25 years for the rapists. But within Mennonite circles, doubts continue to be aired about the imprisonment of the men. They too protest their innocence, claiming their initial confessions in Manitoba were forced under threat of torture. The culture of abuse in the old colonies – physical and sexual – has often been commented on. And, as Linda Pressly reports, it’s partly this that gave the impetus for the foundation of one of Bolivia’s newest Mennonite communities. Hacienda Verde has been hacked out of virgin forest, and is home to 45 families. These are people who were excommunicated in their old colony homes, often because they rejected the harsh rules of conservative Mennonites – rules that govern every facet of life, from the clothes and hairstyles that are allowed, to the rejection of any kind of technology.

The dangers of flying in the great wilderness of the Brazilian rainforest. When a light aircraft carrying two families from a local Indian tribe disappeared over the Amazon in December, relatives scoured the rainforest for weeks until hunger and sickness forced them to give up. The Brazilian authorities ignored appeals for an official ground search – just as they’ve ignored appeals over many years to regulate local flights in the Amazon. Without air traffic control, pilots must fly clandestinely – making already-hazardous travel between the tiny landing strips even more dangerous. Now, Brazil has a new right-wing president, Jair Bolsonaro, who has spoken out against the communal rights of indigenous people – and, as Tim Whewell reports, tribal leaders fear the failure to find the missing plane may be a sign of growing official indifference to their needs. Producer in Brazil, Jessica Cruz.
