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.

Mariko Oi investigates forced confessions of suspects in the Japanese criminal justice system. She asks if the use of prolonged questioning and other dubious tactics by police and prosecutors might be one reason for Japan's astonishingly high conviction rate.

Lucy Ash asks what the explosion in popular protest over a Chinese-backed copper mine says about changes in Burma and asks if this is a test case for the government's commitment to democratic reforms.

Farmers' daughters Aye Net and Thwe Thwe Win have led thousands of villagers in protest against what they say is the unlawful seizure of thousands of acres of land to make way for a $1 billion expansion of a copper mine run by the military and a large Chinese arms manufacturer. They have been thrown in jail and they have been harassed by their own police and military, and yet they have refused to back down.

Their bravery has been celebrated by the poet Ant Maung from the nearest big city Monywa, who wrote: "The struggle made them into iron ladies. . .This is life or death for them - they will defend it at the cost of everything."

Burmese officials and the Chinese company say the Monywa copper mine will create jobs and bring prosperity to one of the poorest and least developed nations in Asia. But the villagers complain about pollution, damage to crops and the loss of fertile land.

A violent crackdown on the protestors was a stark reminder that the country's transition to democracy remains fraught with difficulties. Some suspect the government acted to avoid scaring away foreign investors. Others say the brutal response shows Burma's military leaders are still in charge behind the scenes and that they are not prepared to tolerate any dissent which encroaches on their economic interests.

Meanwhile there is a rising tide of Sinophobia in a country which feels overshadowed by its powerful northern neighbour. How the mine dispute is resolved may provide vital clues about the future of Burma.

For decades, Poland has been a country of emigrants travelling to build new lives abroad, not least in the UK. But could things be about to change? Paul Henley travels to the country at the eastern edge of the EU, where the financial crisis has, so far, been avoided. He meets the migrants already making a life in Europe's least multicultural society, and explores the conditions that suggest Poland could be on the cusp of becoming a destination; home to a new wave of migrants.

The city of Misrata arguably suffered the most during the Libyan conflict as missiles rained on it for months on end. By the end of the revolution though, fighters from Misrata had exacted their revenge on neighbouring towns and had been responsible for the capture of Colonel Gaddafi, as well as Gaddafi strongholds. More recently Misratan fighters have been in action against the city of Bani Walid. Many residents of Bani Walid, accused of being Gaddafi supporters, have been expelled from their homes. Misrata has, effectively, set itself up as a city state, outside the control of Libya's new government.

Linda Pressly investigates why rape and sexual abuse is so common in America's huge prison system - and asks if new measures to fight it will succeed.

Many schoolchildren in South Africa's northern Limpopo province have gone for months without school textbooks. There was money to buy them. There was also a contract to deliver the books. Yet they didn't arrive. Students and parents are furious with politicians of the governing ANC - and say the problem is due to mismanagement and corruption. They say the issue typifies the faults of the political system, and that their children have been the victims. Rob Walker investigates the mystery of the missing textbooks.
