Most people would agree that it's good to talk. Add up the number of hours a day that you spend either talking or listening - you might be surprised just how much of a communicator you are!
In Europe, the telephone is one of the main ways that we communicate with each other. Most people take it for granted that they can use either a land-line
or a mobile phone whenever they want to.
Yet around the world, many people live without any telephones at all. Imagine how hard it would be if the only way you could communicate with your friend who lived five kilometres away was to walk to their house and talk to them face to face. Think how frustrating it would be if they were out when you arrived!
These are the sort of problems facing the people of Chanta Alta, a town in the mountains of Peru. This case study tells the story of their determination to use communication systems to improve their lives.
