A new report says thousands of lives could have been saved in East Africa if aid agencies and governments had helped the starving people there more quickly.
Oxfam and Save the Children say it took over six months to get help to areas suffering from famine.
They say aid could have reached the region a lot sooner.
Between 50,000 and 100,000 people died in Kenya, Ethiopia and Somalia last year.
The charities say that the governments of Kenya and Ethiopia did not admit to how big a problem there was.
They also say that aid agencies were slow to respond because they felt they'd seen the same problem too many times before.
