"In a speech to his fellow Ghanaians in the early 1900s, the visionary educator, Dr. J.E. Kwegyir Aggrey, declared, “The surest way to keep a people down is to educate the men and neglect the women. If you educate a man you simply educate an individual, but if you educate a woman you educate a family.” According to the World Bank, the good news today is that girls have crowded into school in record numbers over recent decades. This is very valuable progress, since the education of girls and women is one of the most crucial elements of lasting and sustainable economic and social development. Although there is hope and obvious improvement at a global level, certain regions are still falling behind." from
