Australia is famous for its unique wildlife and landscapes. But Australia also has the highest mammal extinction rate in the world, and there are big declines in frogs, reptiles, and birds caused by introduced predators and land clearing. Some species are hanging on in small numbers on private land. Could paying farmers and indigenous landowners to return parts of their properties to nature or turn them into carbon farms help solve Australia’s biodiversity crisis?

ABC producer Belinda Sommer takes you to the wide plains and sub-tropical forests of Australia to meet the farmers who are combining commerce and conservation.

The United Nations’ children agency, Unicef, has said that almost two thirds of Ukraine’s 7.5 million children have been displaced during the six weeks since Russia’s invasion.

One of Russia’s key targets has been the southern port city of Mariupol. Thousands of civilians are dead, many more have been left trapped and face an horrendous struggle for survival. Pastor Gennady Mokhnenko is a chaplain from Mariupol. He describes what he has seen and heard in the city, and his efforts to help children to escape. He is joined in conversation by Vasylyna Dubaylo, director of the charity Partnership for Every Child. She’s currently in Poland and has been helping foster children find Ukrainian families.

The war has now separated millions of people in Ukraine from loved ones/ Host Ben James introduces us to Olha and Andrii, a young married couple. Olha took an opportunity to leave with her younger siblings, but is now more than five thousand miles away in Canada. Andrii remains in Ukraine, wondering if he will be called upon to fight for his country. Neither of them know when or if they will see each other again, and they discuss how the war has changed their lives.

Beirut, 1974. It is the height of the Cold War. A prominent Yemeni politician is shot dead in his car. Some say, had he lived, Yemen would be a different country today. The killer was never caught, the assassination never investigated.

Political assassinations in the Middle East are almost always unsolved, and reliable evidence can be extremely hard to find. The lack of accountability in these cases is often seen as the reason for the pervasiveness of assassinations in the region. In Yemen, power struggles over the last 60 years have left a long list of murdered political figures. One particular case, the unsolved murder of Yemen’s former foreign minister in 1974, sent shockwaves across the country, and was covered widely in the region and then in the West. Mohamed Noman was a liberal and progressive politician who was building a different path for Yemen, away from authoritarian rule. His death at the early age of 41 had arguably paved the way for decades of military rule in Yemen.

In this documentary, his granddaughter, Mai Noman, sets off on a mission to investigate who could have been behind his murder, almost 50 years after his death.

Hundreds of thousands of Russians have fled abroad since its invasion of Ukraine, afraid of growing repression in their country, and increasing international isolation. Most of the new exiles are young, well-educated professionals – writers, teachers, artists, IT workers – who fear they could be arrested and jailed for expressing opposition to the war, and even drafted into the army. Tens of thousands have escaped to Russia’s neighbour Georgia, where some are involved in humanitarian efforts to help the Ukrainian victims of the war.

But Georgia itself, invaded by the Kremlin in 2008, has a tense relationship with Russia. Tim Whewell travels to Tbilisi, Georgia's capital, to meet some of the new exiles, and finds they’re not universally welcome. They’re accused of arrogance, of raising property prices – and possibly providing a pretext for the Kremlin to intervene again in Georgia.

In the forests surrounding Biamanga, a sacred mountain for the Yuin people of south-eastern Australia, traditional indigenous fire practitioners are preparing to bring fire back into the landscape. Not the raging fires that threatened to destroy it in the deadly Black Summer bushfires of 2019, but cool fires that will help protect and revitalise the land and help restore habitat for the elusive population of koalas who have survived in this forest against the toughest of odds.

With Russian forces withdrawing from some areas of Ukraine, details are emerging of the death and destruction they have left behind. In Borodyanka, 60 km north-west of Kyiv, the main road through the town is lined with destroyed and burnt-out buildings, vehicles and tanks. Olga and Ira lived there and have sent us messages, describing how their homes were bombed. We hear from Vitaliy Shevchenko, the Russian Editor for BBC Monitoring, who as well as covering the war for us, has been trying to get his parents out of Ukraine to safety.

It is 60 years since the Algerian War of Independence. But it still casts a shadow over the present. As France goes to the polls to elect a new president, Edward Stourton presents stories from the country's colonial past which still affect day-to-day life. He tells the surprising story of how, in the 1870s, a tiny insect called phylloxera created the climate for the Algerian War. He hears about the intriguing story of a knife abandoned in a house in Algiers on a night in March 1957. And he talks to the "Milk Bar Bomber", immortalised in the film The Battle of Algiers.

Just before Christmas, 2021, Joel Vilard was driving his cousin home on a dual carriageway just south of Rennes in Brittany. Suddenly, a bullet flew through the window and hit the pensioner in the neck. He later died in hospital of injuries accidentally inflicted by a hunter firing a rifle from a few hundred metres away. A year earlier Morgan Keane, was shot dead in his garden, while out chopping wood. The hunter says that he mistook the 25 year old man for a wild boar.

Mila Sanchez was so shocked by her friend Morgan’s death that she collected hundreds of thousands of signatures to change the hunting laws. She gave evidence to the French Senate and put the topic on the political agenda. The Green Party is now calling for a ban on hunting on Sundays and Wednesdays. But the Federation National des Chasseurs, which licenses the 1.3 million active hunters across France, is fighting back. It argues hunting is a vital part of rural life and brings the community together. Its members were delighted when President Macron recently halved the cost of annual hunting permits.

Yet public opinion, concerned about safety and animal rights, is hardening against hunting and the battle for la France Profonde is on. On the eve of presidential elections, Lucy Ash looks at a country riven with divisions and asks if new laws are needed to ensure ramblers, families, residents and hunters can share the countryside in harmony.
