“Literacy is a bridge from misery to hope”, in the words of the former Secretary-General, United Nations Kofi Annan. Women literacy and education is crucial to the advancement of girls and women. Education helps in improving the lives of individual families, in turn facilitating economic development of the poor communities world-wide, reiterates the World Bank Report of 2014. In 2015, the United Nations in its universal call, to cease hunger, poverty, AIDS and discrimination against women and girls adopted the Sustainable Development Goals or SDGs or the Global Goals. The seventeen SDGs are intertwined and integrated in a way, if action is taken in one area it has a rippling effect in the other areas too. The aim of SDGs in short is to protect mother earth, its inhabitants, especially humans so that prosperity and peace is ushered in by 2030. In many societies across the globe, draconian traditions and values, issues and problems prevent the girl from accessing her right to education. Her gender with its accompanying inequality; age- old customs and traditions such as the child marriage; economic conditions; the social stigma associated with women’s and girl’s education keep her out of the portals of personal, social and sustainable development. What follows is the endless vicious cycle of poverty, overpopulation, poor health, a country’s sustained social and economic paralysis and rampant gender- based violence. The interconnectedness of the SDGs means that success in achieving one SDG will only help achieve the next SDG. So simply put education of girls and women is not a standalone SDG it can in fact be the key to achieving all the SDGs. The chapter Women Education: The Key to Sustainable Development will explore and delve into how women education becomes the key not just for development of the half of the population of the world, but lead to the sustainable development and the achievement of all SDGs which are important for global development and well-being of humankind!
