1. Global Food Security

3.  One billion people throughout the world suffer from hunger, a figure which has increased by 100 million because of the global financial crisis, says the UN.  The UN's Food and Agriculture Organisation (FAO) said the figure was a record high.  Persistently high food prices have also contributed to the hunger crisis

4. The seriousness  In 2009 "No nation is immune and, as usual, it is the poorest countries and the poorest people that are suffering the most," said the annual report of the UN's Food and Agriculture Organization (FAO) and the World Food Programme.  The FAO says Asia and the Pacific has the largest number of hungry people - 642 million - followed by Sub-Saharan Africa with 265 million WORLD HUNGER Asia-Pacific: 642m Sub-Saharan Africa: 265m Latin America and Caribbean: 53m Middle East and North Africa: 42m Developed world: 15m Source: FAO

5. Stats  The UN said almost all of the world's undernourished live in developing countries, with the most, some 642 million people, living in the Asia-Pacific region.  In sub-Saharan Africa, the next worst-hit region, the figure stands at 265 million.  Just 15 million people are left hungry in the developed world.  "The silent hunger crisis - affecting one-sixth of all of humanity - poses a serious risk for world peace and security," said Jacques Diouf of the UN.  "We urgently need to forge a broad consensus on the total and rapid eradication of hunger in the world and to take the necessary actions."

6.  The Global Hunger Index - a survey published by the International Food Policy Research Unit (IFPRI) - reveals that the Democratic Republic of Congo has seen the steepest rise in hunger since 1990, followed by Burundi, the Comoros and Zimbabwe.  However, it says some countries have dramatically improved levels of malnutrition since 1990, including Vietnam, Brazil, Saudi Arabia and Mexico.
