Writer Andrew Brown tries to find out if the rural heart of Sweden still lives on in the modern age. In an entertaining and unpredictable journey he goes in search of wolves, egg-tossing merrymakers and the ideal of the Swedish summer.

Brazil is getting ready to host the 2014 World Cup. But the preparations have become marred in controversy. And leading the charge against over-budget stadiums, vested interests and corruption is an unlikely figure: Romario. Brazil's World Cup-winning footballer has transformed himself into a serious, hard-working politician. Tim Franks meets him for Crossing Continents. Is this a genuine transformation for one of Brazil's most notorious celebrity bad-boys?

Two and a half years ago, oil started flowing from Ghana's first commercial offshore oilfield. Shortly after the taps were turned on, Rob Walker visited the hub for the new industry: the once sleepy port of Takoradi. He found a mixture of ambition and uncertainty in a rapidly expanding boomtown. Rob now returns to Takoradi to meet people he met last time and find out whether their dreams have been realised.

Mobeen Azhar travels to the Pakistani city of Quetta to investigate how it has become the scene of violent and indiscriminate attacks by Sunni militants against the local ethnic Hazara community. It's a city which has become effectively a no-go area for foreign journalists due to the persistent and intensifying violence. Mobeen tells the story of a single day in January of this year when over 100 people lost their lives in twin bombings in Quetta. Claiming responsibility was the Sunni militant group Lashkar-e-Jhangvi. Mobeen retraces the story of the bombings, and examines the growing security concerns in a district dominated by the Shia Hazara community.

He speaks to Fayyaz Mohammed, a candidate in the forthcoming elections who has links to Lashkar-e-Jhangvi, and talks with Paul Bhatti, who until recently was the Pakistani Minister of National Harmony. Bhatti blames the government's inability to enforce "effective policy" on Pakistan's long history of military dictatorship. Azhar meets blast survivors and the families of victims, and finds out how the security situation is causing many young Hazaras to leave Quetta to seek a better life elsewhere - despite the dangers of putting their lives in the hands of people smugglers.

Belarus has been described as the last dictatorship in Europe. Few dare speak out against President Alexander Lukashenko and his ruling elite. But the opposition has found a way of making its voice heard through an academic community which has taken refuge abroad.

Lucy Ash visits the European Humanities University which teaches Belarusian students on its campus in neighbouring Lithuania. She talks to teachers and students, many of whom commute back and forth across the border. Is the EHU devoted to intellectual freedom and training future leaders of Belarus or is it a "trampoline for emigration" to the west?

Insecurity dominates the lives of millions of Mexicans, who are caught between the murderous drug cartels and absent or corrupt law enforcement. So, communities have begun to take the law into their own hands, and Crossing Continents reporter Linda Pressly travels to the southern state of Guerrero to meet a fledgling vigilante force which has grown into an organisation numbering thousands of members.

Since coming into force earlier this year, dozens of arrests made by untrained, armed civilians hailing from local pueblos and the local community has largely been supportive of their work.

But these community police organisations, as they are known, have no legal authority, and should not be carrying guns in the street - and amid claims that some are using violence to enforce the law, Crossing Continents asks who is keeping the vigilantes in check?

Twelve years ago Lucy Ash investigated Ukraine's fight against HIV infection, which was mainly caused by injecting drug users. After the Orange Revolution in late 2004, the government promised to do everything it could to fight the disease and the situation seemed to improve. But now Ukraine has the second highest infection rate in Europe, surpassed only by Russia. Around the world, other countries are managing to reduce rates of HIV infection and AIDS-related deaths. Lucy Ash travels to Kyiv and Odessa to see why fighting HIV is so difficult in Ukraine.

The fate of hundreds of people who went missing during Nepal's brutal civil war is threatening to undermine the country's fragile democracy. Around 100,000 people were displaced during the bloody insurgency and an estimated 17 thousand were killed. A peace agreement was signed six years ago in which both sides promised that war crimes would not go unpunished. But relatives are still waiting for justice. Joanna Jolly finds out why the scars from the conflict are still raw despite attempts by both sides to bury the past.

The Oyu Tolgoi mine in Mongolia's freezing Gobi Desert is one of the the world's biggest - extracting a vast seam of copper, gold and silver the size of Manhattan. It's turned this country of camel and yak herders into the world's fastest growing economy. Fancy boutiques, top-end car dealerships and coffee shops are springing up across the capital. But, as Justin Rowlatt discovers, riding the boom is not easy. He meets a rapper who says the government is simply selling the country's assets to its old rival, China. And there are fears from foreign investors about attempts by the government to increase its income from the Oyu Tolgoi mine. Can Mongolia become prosperous while sharing its new-found wealth - or will it kill the goose before it has laid any gold (or copper) eggs?

In a major investigation, Natalia Antelava reports on the abduction of tens of thousands of young girls in India for forced marriages. Thousands more are sold as prostitutes and domestic servants. She follows the route of the traffickers, who take girls from destitute households in places like West Bengal to wealthier areas in Northern states, where a shortage of women is blamed by many on sex-selective abortions. It's a problem the United Nations describes as of 'genocidal proportions'. Natalia joins campaigners and police fighting the trade and hears the stories of the trafficked girls and from a trafficker himself.
