Crossing Continents

South Korean women, tradition says, are hard-working, respectful to family, and know their place in Korea's Confucian hierarchies. But the country's rapid economic development has meant some startling changes below the surface of that conservative social structure. Perhaps the most controversial is the advent of Host Bars - all night drinking rooms where female customers can select and pay for male companions, sometimes at a cost of thousands of dollars a night. Originally set up to cater to off-duty 'hostesses' and female escorts, they're now proving popular with many other women too. The growth of the industry is throwing up new questions for South Korea's sociologists and politicians as they struggle to reconcile the country's traditional values with the effects of its rapid development. The BBC's Seoul correspondent Lucy Williamson reports.

Karachi is facing a drugs epidemic. Pakistan's sprawling port city has an estimated half a million chronic heroin addicts. The drug is cheap and easily available as it comes across the Pakistan/Afghanistan border, before being shipped to Europe and the US. Mobeen Azhar finds out how a charity is trying to help addicts and their families.

An NGO called the Edhi Foundation operates what is thought to be the world's largest drug rehabilitation centre. It's here that Mobeen meets brothers Yusaf and Husein who have checked themselves in. Patients who volunteer for treatment like this can leave whenever they feel ready. But the majority of patients, like 24-year-old Saqandar, are brought in by their desperate relatives, and according to Edhi rules, only the family can decide when they will be released.

The centre offers heroin users food and painkillers to ease the physical symptoms of withdrawal - but conventional treatment like methadone is not available. So does enforced cold turkey really work?

Mobeen follows the stories of three heroin addicts and finds out how the stress of their addiction takes its toll on them and their families.

Rwanda is a nation of bicycles; large cumbersome machines, piled high with sacks of coffee or potatoes, so heavy they can only be pushed up the steep winding roads in this "land of a thousand hills."

Rwanda -- a country known only for the genocide of 1994, when an estimated 800,000 people, mainly ethnic Tutsis, were murdered in cold blood in a mere 100 days -- is also a nation in need of heroes.

It may now have found them: lycra-clad athletes in helmets and wrap-around sunglasses on five thousand dollar racing bikes. They are Team Rwanda, the national cycling team, its tightly packed and brightly coloured peloton now a familiar sight on their training rides on the roads around Ruhengeri in the country's north-west, not far from the border with Uganda.

For this week's Crossing Continents Tim Mansel has spent a week with Team Rwanda as they prepare for their latest international competition, the Tour of Eritrea. The team assembles on a Monday night from all over Rwanda. They come by bike, some after riding for three or four hours, one after a ride of six. Their week is a series of gruelling rides, nutritious food, and daily yoga, all under the critical eye of their outspoken American coach, Jock Boyer.

It's impossible to spend time in Rwanda without being confronted by the genocide. A large purple banner adorns the main street in Ruhengeri, its message unmissable - Jenocide, it proclaims - and this year's slogan: "Learning from History to build a bright future." And only a few hundred yards from where the riders live is the town's genocide memorial, a walled garden dominated by a disturbing monument - the figure of a man pleading for his life and a machete that appears to be dripping in blood.

Team Rwanda is not immune from the genocide, indeed it makes explicit connections. Its website features biographies of several of its riders: Rafiki Uwimana, a small child in 1994, sent by his parents to live in the countryside to escape the horrors of the capital Kigali, forced to hide in the forest from the Hutu militias, and almost dying of malaria before being saved by the Tutsi RPF militia invading from Uganda; or Obed Rugovera, who lost three siblings and two uncles in the carnage.

"The genocide has affected every one of the riders profoundly and you can feel it even without talking about it," says the coach, Jock Boyer. "Cycling...gives them the hope that they can buy a house, provide for their family, do something they're good at and that they're recognised for and that the country is not just going to be known for a genocide.".

The state-of-the-art Aeropuerto Don Quijote in Ciudad Real opened for business at the end of 2008. The vision was to create an air hub in the heart of Spain, and its backers believed it would bring business, jobs and tourists to this underdeveloped region. But just over three years later the airport closed - bankruptcy proceedings are on-going. Now it lies abandoned and empty, the silence broken only by birdsong and the occasional whoosh of a high speed train.

In Crossing Continents, Pascale Harter tells the story of a project with its roots in Spain's building boom-years. Was the airport doomed by the economic crisis, as its supporters claim? Or was it always fanciful to imagine that a region with little industry and tourism could sustain an airport with a capacity for five million passengers a year? And what does the building of the airport tell us about the relationship between local business, politicians and the now defunct local banks - the Cajas?

In just three years China's main microblogging site, Sina Weibo, has surpassed Twitter's entire global membership. More than 300 million Chinese are now tweeting, with millions more joining the national conversation every month. Shanghai-based journalist Duncan Hewitt finds out how microblogging is changing China.

Thanks to social media China is witnessing the emergence of a civil society of activists and justice-seekers. These 'netizens' are using Sina Weibo and other services to publicise miscarriages of justice, instances of corruption and environmental issues and force local and central government to act. The victim of a horrific attack shows Duncan how her desperate plea for redress on Sina Weibo led to a nationwide outcry. In Beijing he meets the dogs saved from a grisly death in the dog-eating South thanks to flashmob rescuers organised on Sina Weibo. And a group of mothers who met on Sina Weibo tell him about their campaign to promote breastfeeding across China. None of this was possible before the internet - but where will it all lead?

While some subjects are banned, Sina Weibo has also given Chinese people a new freedom to voice opinions on the news, their lives and their country.

Duncan meets the young people of Chengdu in Western China who are now part of a small but growing graffiti, hip-hop and dance scene. Just 15 years ago there was no way they could communicate with fellow fans, never mind the outside world. He'll visit Youku, China's YouTube, to watch their online X-Factor-style competition as it is filmed. And he'll meet the famous cartoonist using animation to ask questions about the materialism of the young and the detention of his fellow artist and friend, Ai Weiwei.

Writer and broadcaster Maria Margaronis follows the route taken by migrants fleeing war or poverty who are risking their lives to reach the Europe Union. It is estimated that around 75 thousand people are attempting to make the perilous journey each year in the hands of unscrupulous traffickers. They are fleeing from war-torn countries like Afghanistan and Somalia or simply in search of a better life where their economic prospects aren't so bleak. Some of them never make it, suffocating in the back of a crowded lorry or drowning in the fast flowing river that marks the border between Turkey and Greece.

The programme meets up with migrants in Istanbul, on the narrow Bosphorus Strait, which has served as the crossroads of the world for thousands of years. There are children making the journey on their own and one man who has lost his fingers and toes to frostbite on a perilous journey over the mountains from Iran. Two of his companions died. The Turkish authorities confess to being overwhelmed by the numbers which are estimated to be up to 250 people a day. Illegal migrants are detained but seldom, it seems, sent back to the countries they came from. There has been an attempt to clamp down on the people traffickers but there are huge profits to be made.

The most dangerous part of the trip is along Turkey's border with Greece. The Greeks are supposed to be building an eight mile fence but that still leaves a river which is 125 miles long. Traffickers put their charges into cheap inflatable boats and push them across, regardless of whether they are able to handle a boat or to swim. Many of them can't.

For those that do make it, there is no Promised Land but an economic crisis and yet more troubles ahead.

In this week's Crossing Continents, Mukul Devichand tells the stories of Shanghai's rapidly ageing population.

Shanghai's image is youthful and contemporary, of a globalised metropolis buying into a new lifestyle at chains like Ikea. But the Ikea Shanghai store is home to a different category -- and age -- of customer. The store canteen has become a meeting point for elderly singles, looking for love and friendship. It's a story repeated across Shanghai: in places you may expect to millions of young people, you'll see the elderly.

Like the rest of urban China, Shanghai is growing old. A quarter of the city's resident population is now retired, putting it in the same demographic league as countries like the UK or Germany. But ageing in China is different. Its fertility rates have dropped at a speed unprecedented in modern history because its "One Child" policy. 30 years after the policy started, the speed of ageing is faster in China than anywhere else. The burden of ageing is not only coming faster, it's also much also harsher here, because China is still a developing country -- with hundreds of millions of poor people to support, as well as hundreds of millions of additional elderly. That has led to a deep seated anxiety in China: will the country grow too old to get rich?

Nestled amid skyscrapers, Mukul tells the stories of the old Shanghai of inner city districts, a place of tumbledown old blocks where the elderly are concentrated. He meets the couples and families struggling with new complaints, such as dementia and alzheimers, under the burden of low incomes and limited welfare. This story of poverty amid plenty symbolises the deeper worry: of the expense of an ageing China in a country where elderly care has traditionally been managed by the family.

In the same city districts, public and private nursing homes are now opening their doors. These cater to a growing demand from families who can't manage the traditional custom of "many generations under one roof" and represent a big cultural change in China. But who will pay for this kind of care nationally? Mukul tells the stories of the rural migrants, caught between the gaps of China's welfare system -- the millions for whom such care is simply not an option.

What can be done? One solution is to encourage more babies in each family. But that is antithetical to China's historically draconian "One Child" family planning, which is now deeply entrenched in the culture. Mukul visits a family planning centre, which now encourages some couples to have more than one -- and finds the couples aren't always listening. He speaks to Shanghai's leading family planning officials to ask if they are changing the "One Child" policy, and how fast.

At its root, the real problem is not just too many elderly. Rather it's a shortage of young workers, threatening China's economic model itself. A lack of willing youth is a huge issue for a country whose entire business model is based on millions of cheap workers. In the industrial zones south of Shanghai, Mukul tells the stories of a crisis in labour. Will China's factory of the world collapse under the burden of ageing?

Lucy Ash visits Russia's new energy frontier in the Arctic Yamal region and explores the impact oil and gas extraction is having on the indigenous people there.

Gradually but inexorably, reindeer give way to railroads and gas rigs. She goes to stay with a family of herders near the base of the Yamal Peninsula, whose name in the local Nenets language means "the end of the earth." Yamal is home to the largest single area of reindeer husbandry in the world and unlike many indigenous people of the north in Canada, the USA and other parts of Russia, the Nenets herders have proved remarkably resilient. They survived both collectivisation in Soviet times and the chaos of the transition to a market economy in the 1990s. But now there is a new threat as Vladimir Putin has vowed to "turn Yamal into the new oil and gas province of Russia."

Lucy's host in the tundra, Nikolai Khudi, is philosophical about the changing world around him and wary of criticising the state monopoly Gazprom. The flow of oil and gas revenue to the region has brought social benefits such as decent schools and hospitals. Many nomads have willingly given up their traditional lives, and even those who've remained on the tundra now enjoy snow mobiles, satellite dishes and mobile phones. But Nikolai's brother Yevgeny worries their way of life is endangered and that fish may soon disappear from lakes and rivers because of the drilling.

But Moscow is determined to exploit the treasures under the permafrost. The president elect is heavily dependent on hydrocarbons and is counting on them to fulfil recent campaign promises. At the current levels of price and consumption, the natural gas reserves in Russia's Arctic region, would generate enough fuel to feed Europe for around 75 years, with a total value of almost $17 trillion. The fate of this frozen territory thousands of miles from the Kremlin speaks volumes about the Russian state both past and present.

Honduras has the highest murder rate in the world. The People's Funeral Service deals daily with the fall-out from these extreme levels of violence. Set up by the Mayor of Tegucigalpa, the capital city, it distributes coffins, maintains two funeral homes, and even offers a mobile service where employees take everything necessary for a wake - including bread and coffee - to someone's house or local church. All of these services are totally free for poor people in the city.

In Crossing Continents, Linda Pressly profiles this unique organisation, and meets some of the families using its services. Among them, is the family of Ramon Orlando Varela, a 26 year old gunned down in the street after dropping his children off at school. It isn't clear why Ramon was targeted. But a toxic mix of gangs, guns, drug cartels - and fear - pervades Honduras. And it's unlikely his killers will ever be caught. Police corruption is endemic, impunity almost a given.

But in spite of the everyday challenges, the workers at the People's Funeral Service offer what help they can. At least they can lend some dignity to proceedings for families who have almost nothing.

In Bangladesh, twenty percent of girls are married before their fifteenth birthday. Jemy is likely to be one of them. She is thirteen years old and due to marry a cousin in three days time.
