ROME (AFP) - Millions more are going hungry across the world as governments fail to deliver on promised aid, officials warned Thursday on World Food Day. Only a tenth of the some 22 billion euros in assistance for food and agriculture pledged for 2008 has reached the UN food agency, its chief Jacques Diouf said Thursday. "Despite enthusiastic speeches and financial commitments, we have received only a tiny part of what was pledged," Diouf said as he marked World Food Day at the Rome headquarters of the Food and Agriculture Organisation (FAO). His comments came as an expert warned that soaring food prices had pushed up the number of people in the world classed as hungry to 925 million, while more than 100 million had been driven into extreme poverty. Olivier De Schutter, the UN special rapporteur on the right to food, said in a statement in Geneva that the whole system of food production needed to be radically overhauled to ensure an equitable outcome. "The violation on a daily basis of the right to food for hundreds of millions of people worldwide has its roots in an outdated and inadequate production system, rather than in the actual quantity of food available," he said. In Dublin former UN secretary general Kofi Annan said aid for the world's hungry must not be hit by the global financial crisis, which cannot be "an excuse for inaction" at a "critical juncture". "We must maintain our resolve. We can end hunger and poverty. Doing so is critical to Africa and to a healthy and resilient global food system," he told a conference Thursday aimed at highlighting global hunger and advocating better ways to combat it. To underline his point FAO figures revealed Thursday that about a million Burundian children under the age of five suffered chronic malnutrition, while in Ethiopia World Food Programme officials said that 84,000 children were suffering from malnutrition in famine-hit regions of Ethiopia. Nearly 9.5 billion dollars were pledged at an emergency summit on the world food crisis that Diouf hosted in June. "Only 10 percent of the 22 billion euros announced (overall) was disbursed," Diouf said, adding that most arriving funds were earmarked for food aid rather than urgently needed investment in agriculture. Diouf reiterated his fear that the global financial crisis is taking attention away from the continuing food crisis, saying the "number of malnourished, instead of diminishing, grew by 75 million in 2007." Meanwhile, the financial crisis risks further widening the gap between rich and poor, with people on lower incomes bearing the brunt of economic slowdown, the International Labour Organisation warned Thursday. "The gap between richer and poorer households widened since the 1990s," said Raymond Torres, director of the ILO's research arm which produced its "World of Work Report 2008". Global unemployment currently stands at 6.1 percent and is likely to rise, though Torres said it was far too early yet to give any specific prediction for 2009 given continued instability on financial markets. Governments worlwide have thrown hundreds of billions of dollars in taxpayers' money into bank bail-outs but the ILO warned that a large part of the costs will be borne by low-paid workers whose incomes did not rise during boom times. "Ongoing attempts to overcome the financial crisis are of course welcome and, in principle, should help avoid another Great Depression," Torres said. While, Latin America is losing its fight against hunger, as the rising price of staples drives millions to malnutrition, the UN's Food and Agriculture Organization (FAO) said Wednesday. "The good news is that eight million fewer people suffered from malnutrition in Latin America between 1990 and 2005. The bad news is all the benefit of these 15 years has been lost," FAO regional delegate Jose Graziano da Silva told reporters. He presented a FAO report showing that from 1990-2005 the number of people going hungry in Latin America dropped from 53 million to 45 million, while in the rest of the world it grew from 842 million to 848 million. Starting in 2007, however, the trend reversed and now 51 million people in Latin America and 923 million around the world are affected by hunger, the report added. The regression is blamed on the rising price of commodities, in particular wheat and rice in Latin America.
