The theme of International Literacy Day 2012 is Literacy and Peace. This theme was adopted by the United Nations Literacy Decade (UNLD) to demonstrate the multiple uses and value that literacy brings to people. 

Literacy contributes to peace as it brings people closer to attaining individual freedoms and better understanding the world, as well as preventing or resolving conflict. The connection between literacy and peace can be seen by the fact that in unstable democracies or in conflict-affected countries it is harder to establish or sustain a literate environment.

Literacy is a human right, a tool of personal empowerment and a means for social and human development. Educational opportunities depend on literacy.

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. There are good reasons why literacy is at the core of Education for All (EFA).

A good quality basic education equips pupils with literacy skills for life and further learning; literate parents are more likely to send their children to school; literate people are better able to access continuing educational opportunities; and literate societies are better geared to meet pressing development.
