People Fixing the World

In this talent show, it doesn’t matter if you can sing or dance, the winner just has to be honest and good at their job. It’s called Integrity Idol and the aim is to “name and fame” honest government workers - people who reject corruption and refuse to take bribes. The idea is that this creates positive role models to change society for the better. The competition is being run in seven countries around the world. Hundreds of candidates are found from each country, a panel of judges choses the five best, and the public votes on the winner. World Hacks visits the final of the competition in Nepal and asks what difference this approach can make. Reporter: Tom Colls Image Caption: The winner of Integrity Idol Image Credit: BBC

People in many parts of the world are having fewer babies than they were 60 years ago, and that’s worrying some countries. So in order to maintain the proportion of people of working age, governments have come up with campaigns to try to get people to have more children. Polish couples have been encouraged to “breed like bunnies” and speed dating events have been laid on for singles in Georgia. Nicola Kelly visits Norway, which has tackled the issue in a different way, ensuring gender equality, healthcare and education make it attractive to have more than one child. But as the global population grows, does the world really need more babies? We ask whether this just puts greater strain on the planet’s resources.

Do you ever wonder what happens to the people and projects we feature? This week we revisit innovators around the world to see how their schemes have developed. We catch up with the team catching junk in space, and the PODD disease detectives in Thailand tell us how they’ve successfully stopped the spread of infections. We also check in with the man who planned to give QR codes to homeless people so that passers-by can scan them with their mobile phones and donate money.

In 2009, Todd Bol built a small box in the shape of a school, filled it with books and placed it on his front lawn in Wisconsin, in the US. The book exchange soon became a focal point for the community. Now there are more than 75,000 Little Free Libraries in 88 countries across the world, including Sudan, Russia and the UK. They are open to everyone, they never close and have no paperwork or overdue fines. With the motto “Take a book, leave a book”, the aim is to bring people together and get more books into people’s homes.

Many African countries face huge challenges in education. Millions of children completing primary school still struggle to read and teachers that should be in classrooms are routinely absent. Two US entrepreneurs think they have a solution: a network of profit-driven low-cost private schools, called Bridge Academies, that can be created and staffed at lightning speed. Lessons are scripted by ‘master educators’, and teachers read them aloud, word for word, from e-readers. Along with awards, the model has attracted a tidal wave of criticism from teaching unions, NGOs and governments too. World Hacks visits a Bridge Academy in Kenya to ask whether the controversial idea can work. Presenter: Kat Hawkins Reporter: Sam Judah Photo Credit: BBC
