The number of hungry people globally has declined from about one billion 25 years ago to about 795 million today, or about one person out of every nine, despite a surge in population growth, the United Nations reported Wednesday. In developing regions, the number of hungry people has fallen to 780 million today, or 12.9 percent of the population, from 991 million 25 years ago, or 23.3 percent of the population at the time. Despite the finding that nearly 800 million people in the world remain hungry, the report described the progress made as a significant achievement. It said that 72 of the 129 nations monitored by the Food and Agriculture Organization had achieved the target under the so-called Millennium Development Goals of halving the percentages of hungry people in their populations and that developing regions had missed the target by only a small margin. The Millennium Development Goals are a set of eight international objectives, including hunger eradication, established by the United Nations in 2000. "The near-achievement of the M.D.G. hunger targets shows us that we can indeed eliminate the scourge of hunger in our lifetime," said Jos Graziano da Silva, the director general of the Food and Agriculture Organization. Progress was most pronounced in East Asia, Southeast and Central Asia, Latin America and the Caribbean. But the report also illustrated failures, especially in parts of Africa, where ... "extreme weather events, natural disasters, political instability and civil strife have all impeded progress."
