World hunger has been on the rise for a decade with more than a billion people undernourished this year.
A report from the U.N. Food and Agriculture Organization (FAO) found that declining aid and investment in agriculture had been steadily increasing the number of hungry people for more than a decade.
The number of undernourished people started climbing, reaching 1.02 billion this year under the combined effect of high food prices and the global financial meltdown.
"Even before the food crisis and the economic crisis, the number of hungry people had been increasing slowly but steadily," the report said. "With the onset of these crises, however, the number of hungry people in the world increased sharply."
The figure topped the one billion mark in June, compared to 963 million one year ago.
"No nation is immune," the report warned. "As usual, it is the poorest countries and the poorest people that are suffering the most."
The FAO is scheduled to host a World Summit for Food Security in Rome, Italy on November 16 -18.
