“I used to tell young people to stand up for their ideas,” said Tiana Razafinimanana, in Antananarivo, the capital of Madagascar.

Today is International Youth Day, which focuses this year on the civic engagement of young people. As in many countries, young people are Madagascar’s greatest untapped resource. A third of the country’s population is between 10 and 24 years old; if fully empowered, they could be an engine of productivity and progress. B
