People Fixing the World

There are an estimated 350,000 autistic children in Turkey, but only 20,000 to 30,000 of those children are thought to be in education. And because of stigma around the condition, many parents are reluctant to get a diagnosis. Zafer Elcik’s younger brother is autistic and was unable to read or write. But Zafer noticed that while his brother’s attention span was usually very short, he would happily spend an hour playing on his smartphone. So Zafer created Otsimo, an app with a range of games, to help his brother read and write. Now Otsimo has 100,000 users in Turkey, the US and Canada. Otsimo says it’s “democratising education” for people with special needs. But can an app really make much difference?

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.
