The mountainous archipelago of SãoTomé and Príncipe was once the world’s biggest exporter of cocoa. The twin island nation in the Gulf of Guinea was uninhabited until their discovery by Portuguese explorers in the fifteenth century. They brought slaves to work the land producing cash crops like sugar and coffee. In the 1890s these crops were replaced by cocoa and the islands became known as the biggest cocoa exporter in the world. The plantations were farmed first by slaves and then by forced, exploited islanders. When the horrific working conditions were exposed in the 1920s, chocolate manufacturers switched their source of beans to Ghana and Ivory Coast. SãoTomé’s ignominious reputation as the chocolate nation was over. Presenter Tamasin Ford went to visit the islands to take a look at the cocoa sector now.

Thousands of Russian and Ukrainian sailors crew cargo ships that carry goods around the world, so how are they coping living in such close quarters while their countries are at war? We hear from those anxiously watching events back home, and we get an update on the hundreds of ships stranded in the Black Sea, unable to sail in case they are caught in the crossfire.

The price of bread is soaring in Lebanon. More than half of the country's wheat imports came from Ukraine - they've now stopped because of the conflict.

Inflation also continues to rise to record levels. We speak to ordinary people who are struggling to buy food. Brant Stewart, the founder of Mavia Bakery in Beirut, explains how he's found a solution in growing and milling his own wheat - as well as helping local women.

Rami Zurayk, the Director of the Food Security programme at the American University of Beirut, tells us he believes Lebanese people need to be less reliant on bread in their diet.

We're taking the long view on Europe's energy headache. For decades, Russia has been using its vast natural gas reserves as a powerful political tool. So what can the past teach us about the current crisis? Vivienne Nunis speaks to the author and journalist Oliver Bullough who's been following the gas trail from the USSR to Russia's invasion of Ukraine. Also in the programme, Ajit Niranjan reports from the German coastal resort of Lubmin, where the Nord Stream pipelines transporting Russian gas to Europe come to an end. What do people there make of a future without Russian gas? Producer: Carmel O'Grady. Image: Part of the Nord Stream 2 pipeline. Credit: Getty Images

The BBC’s International Business Correspondent Theo Leggett is in France ahead of the Presidential elections to explore an issue important to many voters – youth unemployment.

In the northeast of the country a quarter of young people aren’t in work, education, or training. We explore what the issues are, the problems with inequality and recruitment.

We hear from Sebastien Bento Soares, CEO of Darquer, a lace manufacturer based in Calais that is struggling to recruit younger workers, André Dupon, director of Vitamine T, a social enterprise that helps unemployed people reintegrate the world of work. Salomé and Soufiane, young people based in Boulogne-sur-Mer, tell Theo what’s going on in their lives and Florence Jany-Catrice, economist at the University of Lille talks about the political issues underpinning the youth unemployment problems.

Technology is being used in creative ways to help Ukrainian people stay safe. From offering refugees spare rooms to targeting humanitarian aid to specific shelters, tech entrepreneurs are developing software solutions to try and help in the war effort. Ukraine is an innovation hub. Before the Russian invasion it was home to hundreds of tech start-up firms. Now many of those young entrepreneurs have had to leave the cities where they worked. Eugene Gusarvo and Andrii Tagansky tell Sam Fenwick they felt like traitors leaving their home city, Kyiv on February 24th but they have found purpose creating a website which has helped more than 3,000 refugees find temporary shelter. Four million people have left Ukraine for neighbouring countries, according the United Nations. Those arriving in Georgia can find support from a service set up by 37 year old Stanislav Sabanov. Originally from Russia he says he wants to help because he disagrees with the war. But there are concerns this new tech might be exploited by criminal gangs. Human Rights organisations are warning that there are not enough online checks and sex and human traffickers might use them to target vulnerable people. So could this new technology do more harm than good? Presenter / Producer : Sam Fenwick (Image: tech entrepreneurs; Credit: Eugene Gusarvo and Andrii Tagansky)

We’re in Queensland, home to a tourism industry that – usually – contributes billions of dollars to the Australian economy. The coronavirus pandemic saw the country's borders close for the best part of two years, so how did business owners cope without their usual customer base? Vivienne Nunis speaks to the owner of a mini golf course, a scuba diving company and a restaurant on the Queensland coast. We also hear the tale of José Paronella, a Spanish migrant who built a pleasure garden and ballroom deep in the tropical rainforest. Image: a kangaroo on an Australian beach. Credit: Getty Images.

Millions of Ukrainians have fled the country since the Russian invasion began, some leaving with little more than the clothes on their backs. It's prompted an outpouring of support from around the world - with ordinary people loading lorries with donations and shipping them thousands of miles to help refugees. We follow the aid trail from a small business in north west England to the Ukrainian border and explore whether it's better to give goods or money.

We'll hear from Bob Kitchen, the International Rescue Committee's head of emergencies about giving cash directly to refugees and from Joung-ah Ghedini-Williams, Head of Global Communications at UNHCR about sustaining the support going forwards.

Rahul Tandon reports on the thousands of young Russians who have decided to leave the country since it invaded Ukraine. Economist Konstantin Sonin tells us as many as 300,000 may have travelled to countries like Armenia, Georgia and Turkey. Sanctions have made it harder to do business and the weaker rouble has devalued assets. Two businessmen, now living in exile, tell their stories, and we also hear from those who’ve chosen to stay, like Moscow journalist Tatyana Felgenhauer. Plus, former Russian prime minister Mikhail Kasyanov explains the economic impact of losing skilled workers.

The secretive Wagner Group has a history of violence in Africa. In this episode, we ask why leaders are outsourcing security to an unaccountable army accused of murders, rapes and torture. We look into the crimes they're accused of committing, the governments they're keeping in power and the business deals making it all possible.

Aanu Adeoye, an Africa expert at London's Royal Institute of International Affairs, tells us about the propaganda machine behind Wagner. Keir Giles, a Russia specialist at Chatham House, explains just how intertwined the group is with the Russian state, and Dr Sorcha MacLeod, chair of the UN Working Group on the use of mercenaries, explains why the presence of groups like Wagner in unstable countries often makes things worse.
