The action of the UNESCO in the fields of Sciences is based on the firm conviction that the International scientific cooperation  not only facilitates the sharing of scientific knowledge, but also constitutes an essential element in the establishment of Peace between Nations.

UNESCO helps Member states in conducting political reforms to strengthen their national scientific systems.

Furthermore, the Organization carries out innovative Programs in the domains of the Oceanography, Safety of water supplies, reserves of Biosphere, Geology, Ethics of Sciences, and other related themes.

The mandate of UNESCO for Sciences also covers questions from Social and Human Sciences, such as the promotion of Intercultural dialogue and Democracy, the elimination of doping in Sports, the management of Social transformations and Bioethics.
