G8 leaders have been accused of neglecting a pledge to fight hunger in poor countries.
Anti-poverty group ONE said the drought crisis in east Africa is a "wake-up call" to Governments who pledged to help feed the hungry in Africa two years ago.
A spokeswoman from the group said leaders of the rich world meeting at the G8 summit in Italy in 2009 pledged 22 billion US dollars (£13.7 billion) to go towards agricultural projects designed to put Africa on the road towards food self-sufficiency, rather than on emergency aid during famines and disasters.
