**7.3 Vulnerability analysis and mapping methodology**

When conducting analyses on food security, the WFP makes use of various types of evaluations, collectively referred to as vulnerability investigation and mapping. The CFSVAs stand out as the most important of these evaluations. These studies are conducted in nations that are prone to crises and suffer from food insecurity in order to evaluate the current state of food security and investigate the underlying causes of susceptibility [35].

They obtain primary data by surveying households and rely on secondary data analytics for their research. These surveys contain 13 basic food security evaluation systems, which exemplify the complexity of measuring food security. These modules include food consumption patterns, water sources, sanitation access, household assets, household composition, housing materials, sustainable income livelihood, education, credit availability, livestock, agriculture, external aid, shocks, and coping mechanisms [35]. WFP conducts a variety of methods like food security monitoring ways, crop availability assessment operations, market assessment, emergency food security evaluation, and combined assessment operations as part of its goal to increase governments' ability to decrease hunger [36].
