The actual concept of food security focuses on four food security dimensions: food availability, food access, food utilization and food stability. This study aims to evaluate chronic food and nutrition insecurity, one of the food stability types, in Ethiopia in relation to the four dimensions of food security when affected by longterm shocks characterizing the spatial dimensions of vulnerability defined by contributing and outcome indicators. The results are transformed into geographical information to guide decision making to find where the vulnerable to food and nutrition insecure areas are located. In addition, the study evaluates if there are inclusion and exclusion errors in the number of districts and population receiving assistance under the Productive Safety Net Program (PSNP) and identifies a food security dimension related to child undernourishment.
