People Fixing the World Folgen

Thousands of places in the world don't officially exist on a map. If you're not on a map, it can have implications for how people find you - in times of disaster for example. But a project called Missing Maps is solving that, by using the power of volunteers to make 'invisible people, visible'. At a mapathon in London, volunteers are sitting around their laptops plotting the world. And then in Malawi, mapping experts are putting in essential details to the map. World Hacks travels there to see the finished maps and what impact they could have on communities living there.

to stop people getting caught short. What do you do if you're out and about and can't find a public toilet? Do you sneak into a cafe and hope no one notices, buy something you don't want just for the privilege of using the facilities, or hold it in until you can get home? The number of public toilets around the world is decreasing, making this an increasingly common dilemma. But not in many parts of Germany thanks to a scheme called "Die Nette Toilette", or the nice toilet. Local authorities pay businesses a monthly fee to let anyone wonder in and go to the loo for free. Not only does this dramatically increase the number of available toilets, it leads to big savings for the public purse.

Around 75% of the world's population, approximately 4 billion people, don't have an address. Take a country like Mongolia, with a largely nomadic population, where street names and postcodes can be few and far between. But that could all be changing thanks to just three words. Mongolia's Postal Service was the first in the world to sign up to What3Words, an idea from a British former music executive fed up of bands and equipment constantly getting lost. He's divided the entire world into 3m squares and given each one a different three word phrase, and it could mean that everyone in the world will soon have an address.
