At UN food summit, Ban Ki-Moon warns of rise in child hunger deaths

The summit marked the third time in a decade that leaders had met to discuss food security, yet there are more hungry people today than in 2002 when the first gathering was held, said the London-based think tank International Policy Network.

"Instead of making bland commitments, it is time for governments to take action to reduce the barriers to trade that currently inhibit investments in new agricultural technologies and economic diversification. Only then will they end hunger," said executive director Julian Morris.
