" Literacies for the 21st century" is the Theme for International Literacy Day 2013.
Literacy is at the heart of basic education for all, and essential for eradicating poverty, reducing child mortality, curbing population growth, achieving gender equality and ensuring sustainable development, peace and democracy.
