Jonah is a university student, and a gambler. For him it is the only way he can earn a living. He explains why there are so few opportunities for young Kenyans like him and why betting on foreign football matches has become such an attractive and easy way to make money to fund his university studies. Gambling behaviour expert, Dr Heather Wardle, wants tougher laws on gambling but she wonders how that might impact the University students who need the money they earn from betting.

Journalist Alok Jha argues that if humans are to survive and thrive for the rest of the 21st Century we must urgently transform our relationship with water.

Many of the serious geopolitical tensions over water as a resource that we looked at in the previous episode of this series are rooted in worsening ecological crises. In this episode, Alok shows how the global water crisis is inextricably linked to the climate crisis – and how neither can be dealt with alone.

In Bangalore, we hear how incredible pollution levels led to a lake catching fire, before revealing how local water management decisions play into the global groundwater emergency. Then former Nasa scientist Jay Famiglietti provides a satellite perspective on the problem, showing how water disasters are both a result of the climate crisis and help fuel it.

Back on earth, we hear what this means for Hindou Ibrahim’s pastoralist cattle herder community living on the edge of the rapidly shrinking Lake Chad, and Alok puts water lobbyist Maggie White on the spot to ask why water is not the urgent global priority it should be for leading politicians and policymakers.

Dr Ngozi Okonjo-Iweala's journey to head the World Trade Organisation has been particularly note-worthy. She is the first woman and the first African to hold the position. A trained economist, she was at the World Bank during the financial crisis and, as Nigeria’s finance minister, she faced down corruption.

It's not just her career that sets her apart. As a child she lived through the Biafran War. Years later she faced another crisis: the kidnapping of her elderly mother. But her friends say she does find time for a laugh and the occasional boogie.

Becky Milligan hears about her fascinating life and career from close family, friends and colleagues.

Ihlan Omar is the 37-year-old Somali-born US congresswoman - one of only two Muslim women ever elected to Congress - who's become a thorn in President Trump’s side and on the receiving end of his temper. Omar was one of four congresswomen Trump told to “go back” to where they came from. So who is Ilhan Omar, why has she got the President’s back up - and what's he really up to in targeting her? Mark Coles has been finding out.

As Libya edges towards civil war, Becky Milligan looks at the life of the man behind the most recent conflict, which began with his military assault on the city of Tripoli.

Known as "The Strongman", Field Marshal Khalifa Haftar comes from a family of soldiers and as a young man admired his fellow army student Muammar Gaddafi, who would later denounce him after their disastrous defeat in a war in Chad.

He was given refuge by the Americans and ended up living for twenty years in Langley, Virginia, home of the CIA, before returning to Libya, with the self-proclaimed aim of saving the country from extremists.
