Radio is the mass medium reaching the widest audience in the world. It is also recognized as a powerful communication tool and a low cost medium. Radio is specifically suited to reach remote communities and vulnerable people: the illiterate, the disabled, women, youth and the poor, while offering a platform to intervene in the public debate, irrespective of people’s educational level. Furthermore, radio has a strong and specific role in emergency communication and disaster relief.

2019 Theme: Dialogue, Tolerance and Peace

Broadcasts that provide a platform for dialogue and democratic debate over issues, such as migration or violence against women, can help to raise awareness among listeners and inspire understanding for new perspectives in paving the way for positive action. Radio programming can also build tolerance and surpass the differences separating groups by uniting them under common goals and causes, like ensuring education for one’s children or addressing local health concerns.
