More than a billion people – a sixth of the world’s population – are undernourished and global hunger is getting worse.The UN food agency is warning that efforts to cut the number of hungry people in the world are doomed to failure without a more focused international approach. The UN’s Food and Agriculture Organisation says the global economic downturn has made matters worse. The World Food Programme’s Executive Director Josette Sheeran said: “Today is world food day but for one out of six people on earth they are not even sure that they can fill this cup today. So I am going to rename this as the ‘no food day’ and call upon the world to remember that there are people who have nothing in the cup. One out of six people on earth will go to bed hungry tonight.” The FAO says Asia and and the Pacific has the largest number of hungry people, 642 milion, followed by sub-Saharan Africa with 265 million. The organisation says the World Food Summit target of reducing the number of malnourished people by half by 2015 will not be met without international investment in agriculture and economic safety nets for poorer countries.
