In 2001, UNESCO adopted the Universal Declaration on Cultural Diversity. Next, in December 2002, the UN General Assembly, in its resolution 57/249, declared May 21 to be the World Day for Cultural Diversity for Dialogue and Development.

Held every year on 21 May, UNESCO leads the celebration of World Day for Cultural Diversity for Dialogue and Development highlighting not only the richness of the world’s cultures, but also the essential role of intercultural dialogue for achieving peace and sustainable development.

With the adoption in September 2015 of the 2030 Agenda for Sustainable Development by the United Nations, the message of the World Day for Cultural Diversity for Dialogue and Development is more important than ever. The 17 Sustainable Development Goals (SDGs) can best be achieved by drawing upon the creative potential of the world’s diverse cultures and engaging in continuous dialogue to ensure that all members of society benefit from sustainable development.

Why does cultural diversity matter?

Three-quarters of the world’s major conflicts have a cultural dimension. Bridging the gap between cultures is urgent and necessary for peace, stability and development.

Cultural diversity is a driving force of development, not only with respect to economic growth, but also as a means of leading a more fulfilling intellectual, emotional, moral and spiritual life. This is captured in the culture conventions, which provide a solid basis for the promotion of cultural diversity. Cultural diversity is thus an asset that is indispensable for poverty reduction and the achievement of sustainable development.

At the same time, acceptance and recognition of cultural diversity – in particular through innovative use of media and Information and Communications Technologies (ICTs) – are conducive to dialogue among civilizations and cultures, respect and mutual understanding.
