The jailing of former South African president Jacob Zuma sparked huge unrest in the country, but was there more behind the riots than the fact of his imprisonment?While some believe the riots were not only a reaction to Zuma’s jailing for contempt of court, but a planned attempt to bring the country to its knees, others say poverty and inequality also played its part.Paul Connolly examines the factors behind the riots and asks how the country can rebuild from disturbances that have left many dead and parts of the country in ruins.Producers: Rob Cave and Olivia Noon(Rioters loot the Gold Spot Shopping Centre southeast of Johannesburg, July 12 2021.

Haiti was the first Caribbean country to gain its independence after a successful revolt against slavery. But the country has been troubled ever since, suffering dictatorships, coups and natural disasters.Now its most recent president, Jovenel Moise, has been assassinated. His controversial rule was marred by the rise of gang violence, and protests against corruption and impunity. He upset people in the fields of politics and business too. And as he failed to hold elections, parliament is no longer functioning. So in this edition of The Inquiry, Charmaine Cozier asks: why was the president of Haiti assassinated? And where can the country go from here? Producer: Arlene Gregorius(President Jovenel Moise in the capital Port-au-Prince in 2016. Photo: Hector Retamal /Getty Images.)

China’s decades-long One Child Policy has led to a low birth rate, and a shrinking workforce. It has also been placing a heavy burden on the younger generations who will have to support two parents and four grandparents. It’s predicted that in five years’ time, a quarter of the population will be over 65. With a smaller workforce, the country risks becoming poorer.China tried to address the problem by allowing couples to have two children instead of one, but except for an initial uptick, the birth rate has continued to fall regardless. So now China has introduced a three-child policy. But couples continue to worry about the lack of affordable childcare, and the high financial and emotional cost of raising children. So in this edition of The Inquiry, Tanya Beckett asks: can China raise its birth rate? Producer: Arlene Gregorius(A mother and her child waving Chinese flags near Tiananmen Square in Beijing, China.

Rich people are often able to pay little or no tax compared to their wealth because of the way the system works. In recent years, many have called for changes and reforms so that instead of income, wealth is also taxed. But, wealth taxes are not a new thing. Many argue that they are key for addressing inequality but some say they simply aren’t an effective way of gaining revenue.Charmaine Cozier asks can we make the super-rich pay more tax?Producer: Olivia Noon Researcher: Bethan Head(Activists March In Manhattan NY, calling for a tax on Billionaires.

For the last year discussions about the origins of Covid-19 have divided people all over the world. Some say it came from nature and others believe it could have escaped from a lab. The idea of a lab accident was originally dismissed as a conspiracy theory but it’s starting to gain attention all over again.Now President Biden has given the US intelligence service 90 days to try and investigate the virus's origins further. Many still believe the virus jumped to humans from animals but some say that we need to be open minded until we have all of the data. But could Covid-19 really have come from a lab?

In November 2021, Britain will host the next UN Climate Change Conference, otherwise known as COP 26. Some 200 countries will come together to try to speed up attempts to make the world carbon neutral by the middle of the century. But many countries are already struggling to ramp up renewable energy sufficiently to meet their greenhouse emission reduction targets. So is there another answer out there? Around a tenth of the world's electricity is generated by nuclear reactors. Global generation has slowed in recent years after the nuclear accident in Fukushima a decade ago prompted governments to take a more cautious stance. But with the urgent need to reduce carbon emissions, many prominent environmentalists are now taking another look at nuclear energy.Tanya Beckett asks if nuclear energy can helps us transition away from fossil fuel power.Produced by Soila Apparicio.(Exhaust plumes from cooling towers at the coal-fired power station at Jaenschwalde Germany.
