Theme and significance:
This year’s theme is “Multilingual education – a necessity to transform education". It is observed globally that 40 per cent of the population does not have access to an education in a language they speak or understand. The UN noted that every two weeks a language disappears taking with it an entire cultural and intellectual heritage.
At least 43% of the estimated 6,000 languages spoken in the world are endangered. Only a few hundred languages have genuinely been given a place in education systems and the public domain, and less than a hundred are used in the digital world.
