In a major endorsement for investment in women – the bulk of food growers in the developing world – United Nations Secretary General Ban Ki-moon said food security could not be achieved without women, and that the world’s hungry also needed leaders to prioritise actions. 'Girls and women are society’s best chance to overcome hunger,' Ban told a gathering of world leaders, researchers, farmers and policy-makers at the presentation of the 2012 World Food Prize. Global leaders meeting in the midwest U.S. state of Iowa to discuss strategies to boost food production worldwide say the particularly challenging food security situation in Africa will require mobilising the continent’s best scientific minds, including those of African women.
