Kate Adie introduces stories from North Korea, Canada, Guinea-Bissau, Peru and Jamaica. North Korea sealed its borders when the pandemic struck, and little news from the isolated, oppressive state has leaked out since. The BBC's Jean Mackenzie, with Daily NK, an organisation with sources inside North Korea, has managed to make contact with North Koreans who reveal lives defined by fear - and the growing threat of starvation. Canada is on course for its worst year for wildfires on record. Unusually, there have been many blazes in Quebec - a province not used to wildfires, and which subsequently lacks the specialist firefighters needed to tame forest fires. Nadine Yousif hears how they're already exhausted - and it's still only June. Guinea-Bissau is a major hub for drug traffickers from South America transporting drugs to Europe - and this has fuelled high levels of addiction to crack cocaine. Yet the country has only two drug rehab centres - one of them run by a Pentecostal pastor, who claims to cure addiction through prayer. Sam Bradpiece paid a a visit, and found evidence of staff cruelty and residents being chained to bars and cages. Peru has become the world's largest exporter of blueberries - a fruit native to the northern hemisphere, where it thrives in colder temperatures. So how do they grow it in tropical Peru? Stefania Gozzer has been to a blueberry plantation along Peru's arid Pacific coast to find out. The Empire Windrush docked at Tilbury in Essex 75 years ago. On board were 802 people from the Caribbean, who had made the voyage to find better jobs, and build a better life - but the Windrush Generation also faced hostility and prejudice. Horatio Clare recently visited Jamaica, and found that amid the warm welcomes was a demand for a different relationship between the UK and its former colony.
