Organization for Women in Science for the Developing World

The Organization for Women in Science for the Developing World (OWSD) is an international forum that awards fellowships in science to women postgraduate students from developing nations. Established in 1993, the organisation is based in Trieste, Italy at the headquarters for The World Academy of Sciences. Following the Fourth General Assembly and International Conference in 2010, members voted to change the organisation's name from Third World Organization for Women in Science (TWOWS) to the Organization for Women in Science for the Developing World.

Its former president Lydia Makhubu, encouraged young girls to start at the earliest level primary school in order to be ready to embark on a career in science.
