Ukrainian President Volodymyr Zelensky knows that if he has any hope of victory in the war in his country he needs his international friends to keep backing him. Although the size of that task was pretty clear this week, in both the United States and Europe, when he returned largely empty handed - for now, at least. Russian President Vladimir Putin, on the other hand, says he remains up for the fight and talked confidently about ultimate success. It is now approaching two years of war in Ukraine. Despite both leaders talking of victory, the fighting and losses continue and neither side has been making much progress on the battlefield. In this edition, we hear conversations among Ukrainians. They talk about the emotional impact of the fighting but also how they are able to have plans despite the war. Three residents of Kyiv share their experiences, including Iryna, on how the approach of a second Christmas at war has affected her wedding plans to her British fiance. “When first he proposed I said yeah, we’re going to do it after the war, after we will win,” says Iryna. "But now it’s so long already and I feel like I just paused my life. So we decided to get married next year.” Host James Reynolds also hears from a woman whose brother was captured in the Ukrainian port city of Mariupol and brings together Ukrainians in the UK and Poland.

What does it mean to be a gay Christian in a country where many Church leaders say your sexuality is wicked and even demonic? In 2013, a group of LGBT Christians in Kenya started meeting for Sunday worship, to practice their faith free from homophobia. The community grew and became Kenya’s first openly queer-affirming Church - a sanctuary for diverse believers who feel excluded from mainstream religious spaces. But with calls for new laws to further curtail the rights of LGBT Kenyans, and increasingly open homophobia and anti-gay protests, this sanctuary may be in jeopardy. While some members consider returning to the closet, others are determined to protect their sacred space, come what may.

As hundreds of thousands of Ukrainian soldiers defend their country against Russia, many patriotic civilians are engaged in a struggle that's less risky, but that they believe is also vital. They’re battling for a fairer, less corrupt Ukraine, worthy of its heroes.

In 2013 Iceland made history by becoming the first European country to sign a free trade agreement with China. It was aimed at increasing exports from Iceland to China as well as opening up Iceland to cheaper Chinese consumer goods. Geothermal energy has meant that Iceland is effectively carbon neutral. Its expertise in this area has led to collaboration with China and its geothermal model is changing China's energy mix. One man behind this collaboration is Atli Jonsson, CEO of Arctic Green Energy. Anna Holligan asks him how will geothermal help shape the future needs of China's energy consumption and open further opportunities for collaboration?

Kengo Kuma has a philosophy: to enrich the connection between buildings and nature, “almost tuning-in” to the materials. His architecture is inspired by traditional Japanese design, and he is a serious critic of the global dominance of concrete. Kuma’s mission has manifested in iconic buildings including China’s Folk Art Museum, the V&A in Scotland, and Japan’s National Stadium, built for the 2020 Olympics. Broadcaster Nick Luscombe follows Kuma to Japan’s oldest and largest lake, and to the ancient capital of Otsu, where Kuma is attempting to represent the history of the area not by constructing a new building, but by creating a monument to a legendary cow.

Former BBC Taiwan correspondent Cindy Sui meets two young Taiwanese voters, Shirley Lin and Dennis, who have very different views about the island, its future and its relationship with Mainland China. While one is a committed peace campaigner and seeks to reduce antagonism between Taiwan and China, the other has signed up to train with a citizen's army, to be ready for Chinese aggression. We follow them in their work, with their friends and hear their differing reflections on an island and an electorate being watched by a global audience.

World leaders are currently meeting in Dubai for the United Nations’ COP23 climate summit to discuss how to cope with a changing global climate. At the same time, a new study has suggested that air pollution from using fossil fuels is responsible for 5 million avoidable deaths around the world every year.

Host James Reynolds brings together three young people in India, Uganda and Bangladesh to hear their concerns and what it’s like to live in a country struggling with air pollution.

“I got up, I looked out the window, nothing. I couldn’t even see my own lane. It was extremely sad,” said 12 year old Myra in Delhi, India. “I was getting ready to go to the school. I was going to my bus and I couldn’t see anything. Almost all days smog is covering the entire city. It’s suffocating.”

Three women from the United States, India and the UK - all in their twenties - also share why they decided to not have children in order to help save the planet.

“Every year has become more significant,” says Melissa in London, “and of course making changes in my own life to help the climate like being plant-based and not having children seems to be quite a good decision in that regard as well.”

Sarajevo’s most famous artefact, a 700 year-old Jewish prayer book called the Haggadah, captures the story the city wants to tell about itself. But is it accurate? In Sarajevo, Farrah Jarral joins members of the Jewish community to find out. In a city devastated by conflict in the 1990s, she hears stories about living together, and the wish that Jews and Muslims can still live alongside one another, as they had for hundreds of years. And the story of the Haggadah seems to capture that. Saved from the Nazis by a Muslim and a Catholic, and then again from destruction in the 1990s by another Muslim, it captures the possibility of living together, caring for one another's treasures.

Cyprus is one of the main resting stops for songbirds as they migrate between Europe, Africa and the Middle East. For centuries, Cypriots trapped and ate a small number of migrating songbirds, as part of a subsistence diet. But over recent decades, the consumption of songbirds became a lucrative commercial business and the level of slaughter reached industrial levels. Millions of birds were killed each year as trappers employed new technologies to attract and capture birds. The methods used by the trappers are illegal under both Cypriot and EU law. In the last few years, both the Cypriot authorities and environmental groups have been fighting back, dramatically reducing the number of birds being trapped. Antonia Bolingbroke-Kent sees the trappers in action, and meets those determined to stop the mass killing of birds.
