First developed in 2006, the Index captures three dimensions of hunger: insufficient availability of food, shortfalls in the nutritional status of children, and child mortality. Using data from the Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO), and the United Nations Children's Fund (UNICEF), the Index ranks countries on a 100-point scale, with 0 being the best score (no hunger) and 100 being the worst. A score over 30 is deemed to be 'extremely alarming'.
Since 2006, an update of the GHI is published annually by the International Food Policy Research Institute (IFPRI) in collaboration with two non-governmental organisations - Ireland's Concern Worldwide and Germany's Welthungerhilfe - to make the challenge of hunger more transparent and to report to policymakers, civil society and the media about progress and regress in tackling hunger. The GHI is available in English, German, French, Italian and Spanish.
Despite a moderate decline in world hunger since 1990, the situation remains at a level characterised as 'serious', according to the 2012 Global Hunger Index (GHI). The GHI is a tool designed to comprehensively measure and track hunger globally and by region and country. Re-calculated each year, the GHI provides a simple way of ranking countries with regard to their food security and illustrates trends in hunger worldwide, thereby raising awareness, improving understanding and hopefully triggering hunger-reduction activities.
