The FGGD changes in undernourishment map is a global vector datalayer at scale 1:5 000 000. The map depicts the differences among countries with respect to the difference between the share of the population estimated to be undernourished in 1990-1992 and in 2000-2002, as reported in the FAO publication The State of Food Insecurity (SOFI) in the World 2004. The method used by FAO to estimate the number of undernourished by country is described in FAOSTAT.

The FGGD estimated number of stunted children map is a global raster datalayer with a resolution of 5 arc-minutes. The number of stunted children is estimated according to the lowest available sub-national administrative units: all pixels within the unit boundaries will have the same value, that means the estimated number of stunted children in the unit. Data have been compiled by FAO using three main information: the prevalence of stunting, LandScan global population database and the percentage of children under five. This last information is at national level and its source is UNICEF.

The FGGD prevalence of stunting map is a global raster datalayer with a resolution of 5 arc-minutes. The percentage of stunted children undev five year old is reported according to the lowest available sub-national administrative units: all pixels within the unit boundaries will have the same value. Data have been compiled by FAO from different sources: Demographic and Health Surveys (DHS), UNICEF MICS, WHO Global Database on Child Growth and Malnutrition, and national surveys.

The FGGD prevalence of undernourishment map is a global vector datalayer at scale 1:5 000 000. The map depicts the differences among countries with respect to the share of the national population estimated to be undernourished in 2000-2002, as reported in the FAO publication The State of Food Insecurity (SOFI) in the World 2004. The method used by FAO to estimate the number of undernourished by country is described in FAOSTAT.

The FGGD Digital Atlas consists of more than 100 global maps that allows to analyse food insecurity and poverty in relation to environment. It is subdivided into 6 modules as follows: Module 1 Boundaries and Topography Module 2 Population Module 3 Socio-Economic and Nutrition Indicators Module 4 Environmental Conditions Module 5 Land Use Patterns and Land Cover Module 6 Land Productivity Potential
