A US government aid agency has formed an alliance with a group headed by former UN chief Kofi Annan to try to boost African agriculture.Mr Annan has called for a "green revolution" to solve the food crisis.
The new partnership aims to invest in Africa's inadequate infrastructure, as well as developing new seeds and fertilisers.
Mr Annan says that 40% of African crops are lost after being harvested - a problem which new roads could ease.
The alliance between the US Millennium Challenge Corporation (MCC) and the Alliance for a Green Revolution in Africa (Agra) focuses on small-scale farmers.
Akin Adesina, Agra's vice-president, said the partnership would focus on boosting production in three "breadbasket areas".
These were the Sahel region where millet and sorghum crops dominate; humid zones where root and tuber foods do well and the east and south of the continent where maize is the dominate crop.
"We believe that we can have a green revolution that allows farmers and households in the Sahel to be able to feed themselves while also allowing those who are eating maize, yams and cassava to be able to feed themselves," he told the BBC's Network Africa programme.
