Muslim Malaysians often have complex and tangled views about polygamy. Their feelings and beliefs are not always mirrored by their actions. What role does pragmatism play? What role does faith play? ABC producer Damien Carrick meets an adventure sportsman, an academic researcher, a feminist activist and Malaysia's first female Shariah High Court judge and examines the different attitudes towards polygamy.

Colombia produced a record 1.5 million kilograms of cocaine last year - about 70% of the world’s supply. In the regions where coca is grown, gangs fight for control of territory and smuggling routes, killing anyone who stands in their way. These are some of the most dangerous places in South America. A peace deal signed in 2016 with the FARC rebel group was meant to reduce coca growing by offering farmers alternatives. But instead, cocaine production has rocketed, flooding markets in the US and Europe.

In this Assignment, Michael Buchanan investigates what’s behind Colombia’s booming cocaine trade. He gains rare access to smugglers and producers, as well as meeting the indigenous people who are standing up to the traffickers, and often paying with their lives.

Climate change is lapping at the shores of Poruma, a tropical island in Australia’s Torres Strait. It is a dot in the Pacific Ocean, just two kilometres long and 300 metres wide, that sits halfway between the northern tip of Australia and the south of Papua New Guinea. Christianity came to the Torres Strait in the late 1800s and it has been embraced by the Islanders. But when the people of Poruma gained this faith, they lost parts of their culture and language. Siobhan Hegarty journeys to the Torres Strait where the locals are fighting to save their land, their language and their cultural traditions – before it’s too late.

Academic expectations, job competition and financial pressures are forcing some young South Koreans to give up on relationships, marriage and kids. This phenomenon is known as the ‘sampo’ or ‘give up’ generation. The daily struggle to succeed within a patriotic and competitive culture is a shared experience. The suicide rate in Korea is the second highest among developed countries. In recent years, the quality of life reached such a low point, young people started referring to the country as, ‘hell Joseon’.

In the heart of Hitler’s Nazi Germany, members of the Resistance worked tirelessly and at great risk to themselves to help those whose lives were threatened. Amongst them was Elisabeth Charlotte Gloeden – known as Liselotte or “Lilo” – who, along with her husband Erich, hid Jews in their home in Berlin, before arranging safe passage for them out of Germany. The couple’s efforts went undetected until 1944 when they took in General Fritz Lindemann, who was being hunted by the Gestapo for being part of the plot to assassinate Hitler.

How do you achieve net-zero carbon emissions in just fifteen years? In Finland, a fisherman-turned-climate scientist believes he has part of the answer: re-wilding the country’s peat fields.

Why do we hold our opponents in contempt? Former British politician Douglas Alexander believes that disagreement is good - it is how the best arguments get refined. But, today, public discourse has become so ill-tempered, snide and lacking in respect that we are no longer engaged in a battle of ideas but a slanging match. Time to dial down the rhetoric, rein in the insults - they will persuade no-one that your opinion is worth listening to - and pay attention.

“Did you actually kill hundreds of people, Dad?” This is certainly not a question that many people feel the need to ask their parents. But for a group of young women in Argentina, it was one they could no longer ignore. Their fathers have been accused, held under trial and in some cases sentenced for some of the worst crimes in Argentina’s history – all members of the military and police forces during the country’s last military regime, that kidnapped, tortured and killed thousands of people over a period of seven years. Forty years later, these women have come together and decided to speak up against their fathers. The BBC’s Valeria Perasso followed them on their journey to become a voice in the ongoing public conversation about human rights to help heal the country – and themselves.

Kate Molleson visits the world’s largest island to explore the role of traditional and new music for its communities today. Between the capital of Nuuk and smaller fishing town of Maniitsoq, Kate encounters drum dancers resurrecting a traditional Inuit practice which almost died out on Greenland’s west coast, discovers the political and sonic influence of the Greenlandic language on music from hymn singing to hip-hop, meets artists using their lyrics to engage with issues from the climate to the country’s deep-rooted social problems, and visits a music school offering a safe space to young people.

Psychedelic plants, the spiritual tourism backlash - and sexual abuse. Increasing numbers of tourists are travelling to the Peruvian Amazon to drink ayahuasca, a traditional plant medicine said to bring about a higher state of consciousness. Foreigners come looking for spiritual enlightenment or help with mental health problems like trauma, depression, and addiction. But not everyone is happy about Peru’s booming ayahuasca tourism industry. A group of indigenous healers are fighting back against what they see as the exploitation and appropriation of their cultural heritage by foreigners - who run most of the ayahuasca retreats popular with tourists. This coming together of cultures has thrown up another serious problem too: vulnerable women being sexually abused while under the influence of charismatic healers and this powerful psychedelic.
