Undernourished population:

  • Persons whose food intake falls below the minimum requirement or whose food intake is insufficient to meet dietary energy requirements continuously.

World food status as at 2017:

  • The number of people who suffer from hunger has been growing over the past three years to reach 821 million people (or 11% of world population).
  • About 515 million (11.4% of Asians) of them live in Asia, and 256.5 million (20.4% of Africans) in Africa.
  • 1.5 billion people in the world are affected by one or more forms of micronutrient deficiency (hidden hunger).
  • Prevalences of anaemia in women and obesity in adults are increasing. More than one in eight adults in the world is obese and one in three women of reproductive age is anaemic.
  • 7.5 percent of children under five (50.5 million) are affected by wasting (low weight for height) consequently putting them at a higher risk of mortality.
  • Conflicts and violence, as well as climate variability and extremes (mainly severe droughts, but also floods and tropical storms) are the leading causes of severe food crises.
  • 580 million (17.4%) people in countries with high exposure to climate extremes are undernourished.
  • The percentage of household income spent on food by the richest nations is 10% to 15% only, but reaches 70% to 80% of household income in the poorest nations;
  • Rises in food prices threaten to add additional millions of people to those already suffering from hunger.
