US President Barack Obama has announced a $3bn (£1.9bn) plan to boost food security and farm productivity in Africa, US officials say.
They say the initiative is aimed at alleviating shortages as world food supplies are being stretched by rising demand in Asia’s emerging markets.
Food security is also on the agenda of this weekend’s G-8 meeting.
The summit near Washington is being dominated by Europe’s debt crisis and a possible Greek exit from the eurozone.
