Kate Adie presents stories from France, India, the US, Panama and Spain.

It’s been a year since the UK signed a deal with France to help reduce the number of boats crossing the Channel and break up the smuggling gangs. And whilst the number of crossings is falling, there’s been a sharp rise in migrant deaths, mostly by drowning, as they take ever greater risks to reach the UK. Andrew Harding is in Calais to find out why.

South Korean women are increasingly shunning the dating scene and choosing not to have children. And the country's birth rate recently fell again, to just 0.72. This poses a serious problem for South Korea's economy and its security, with politicians describing it as a national emergency. But, as Jean MacKenzie finds, they've been unable to reverse the trend.

Kate Adie presents stories from Gaza, Turkey, Somalia, Ecuador and Japan.

US President Joe Biden raised hopes that a ceasefire deal was close to being reached this week over the release of Israeli hostages and Palestinian prisoners. But these hopes faded after a tragic incident in which more than 100 people were killed as aid was being delivered to Gaza City. Paul Adams says the incident also highlighted wider problems as the war continues.

Lizzie Porter follows the story of a family who fled Gaza early on in the war, and who fled to Turkey as dual nationals, leaving family, friends and valuables behind. They told her about their new life in Turkey and their fears for those left behind.

After the militant group, Al Shabaab withdrew from the Somalian capital Mogadishu, the city has become safer. Nonetheless the group remains a potent threat. Yet there is an even greater menace in the country: climate change, after severe droughts, followed by flooding forced farmers off their land. Peter Oborne met some of those who were displaced and who are trying to support themselves in other ways.

A project in Ecuador is using the Amazon’s “ancestral highways” – rivers – and a fleet of solar-powered boats run by Indigenous communities to provide a sustainable model of transport for the future.

And we're in Inazawa in Japan, where the Hadaka Matsuri - or Naked Festival - has come up with a solution to flagging numbers of participants: involve women. Shaimaa Khalil met a group of 40 women who took part (in robes) for the first time.

Kate Adie introduces dispatches from Ukraine, Russia, the USA and Georgia.

Sarah Rainsford was in Ukraine when Vladimir Putin first launched his full-scale invasion two years ago, reporting on the defiance and rush to defend the country. On a recent trip back to the border city of Kharkiv, she found a much more sombre mood.

Steve Rosenberg reflects on how the death of Russian opposition leader Alexei Navalny, along with two years of war with Ukraine, has affected the outlook of many ordinary Russians. Many wish for change, but are unclear on how that can be achieved.

Over recent months, the stalled passage of a $60bn military aid package through the US Congress has heightened concerns that Washington’s support for Ukraine is on the wane. Anthony Zurcher reflects on how the current US position has changed since his trip to Kyiv in the weeks before the Russian invasion began.

Georgia has become a prime destination for Russians fleeing the war with Ukraine, especially those escaping conscription. The sudden arrival of tens of thousands of Russians has proved overwhelming at times, and given Georgia’s own past conflict with Russia, not everyone is happy to see them, reports Vitaliy Shevchenko.

Since Russia’s invasion, more than 6 million Ukrainians have sought refuge overseas – but many people have stayed put, often by choice, determined to carry on living their lives as they have always done. Caroline Eden meets some market traders in Ukraine’s southern port of Odessa, who are trying to ensure it's business as usual.

Our Central Europe correspondent, Nick Thorpe, is never far from a border flash-point, and reflects on the characters he has crossed paths with on the frontier of Hungary and Serbia.

Costa Rica is often portrayed as a gold standard of eco-tourism and its Corcovado national park is one of the best places on earth to watch wildlife. But, there are concerns that some species there are in decline, in part due to illegal gold mining, hunting and logging in the region. Qasa Alom has been exploring the challenges.

Kate Adie presents stories from Israel and Gaza, Guyana, Finland and the USA.

More often, news organisations have relied on Palestinian journalists already living and working in Gaza, who

After Guyana discovered it had substantial oil reserves almost ten years ago, its economy was quickly transformed and it's now the world's fastest growing economy.

Michelle Jana Chan went to see how the country had changed.

Alexander Stubb was elected as Finland's president in polls last weekend, heralding a more hawkish approach to Russia.
