However, the proportion of people who are undernourished declined from about 20 per cent in 1990-1992 to 15 per cent in 2008-2010. Progress has been uneven across regions and the 2007-2008 food and financial crisis posed additional challenges. Under current conditions, the target of halving the proportion of people suffering from hunger by 2015 will not be met in sub-Saharan Africa and South Asia. Individuals may take in enough calories for daily subsistence, but still suffer from “hidden hunger” with low levels of micronutrients owing to the lack of diversification of diets.
