Constructing a Database for Food Security Assessments in Southeast Asia summed up into an aggregate score. The food groups with high energy content, good quality protein, and micronutrients receive the highest weight of 4, and sugar and oil the lowest of 0.5. Households with a FCS <35 are then classified as food insecure. A score of 21 was indicated to be the minimum. The household diet diversity score (HDDS) is also derived from consumption recall surveys, but preferably for a 24 hours recall period (Hoddinott 1999; Jones et al. 2013; Jones, Shrinivas, and Bezner-Kerr 2014). It is an indicator for dietary q uality and captures how many food items or food groups a household has consumed. It distinguishes between 11 food groups and simply sums the number of different food groups. Accordingly, the HDDS ranges between 0 and 11 for households with the most diverse diet. Thresholds dividing households into high- or lowdiversity groups are not provided. Finally, the household food insecurity access scale (HFIAS) (Swindale and Bilinski 2006) is a survey-basedoutcome indicator where respondents answer a set of nine questions that give a subjective measure of a household’s food insecurity status. These include domains like anxiety/uncertainty about food access, quality of food, and quantity of food. The set of questions identified for each domain represents the experience of food insecurity (access) under that domain. The questions are meant to be universally understandable and in principle can be adapted to different cultural contexts provided consistency of the concept is maintained. Anthropometric measures are usually applied as a proxy of food utilization and reflect chronic or acute mal- or undernourishment (Jones et al. 2013). The most frequently used measures are weight for age (WFA) and height for age (HFA), both referred to children with age <5 years. If the weight of a child is too low for the height, the term “wasting” is used. Stunted children are too short for their age, indicating maland undernutrition (de Haen et al. 2011). Child underweight combines the two indicators and is defined as a low weight for age ratio. To sum up, the choice of indicators for assessing the food security status is crucial. Different indicators often come to very different assessments for the same food security situation (de Haen et al. 2011). Development organizations such as FAO often suggest that food security assessments should include several indicators in order to capture the multidimensional facets of food security. There is currently no consensus which indicators should be given priority to and to what extent they are complements or substitutes (see, e.g., Maxwell, Vaitla, and Coates 2014; Headey and Ecker 2013; Coates 2013; Jones et al. 2013; Carletto, Zezza, and Banerjee 2013). Headey and Ecker (2013) stressed that the accurate measurement of food security at micro or macro levels is of vital importance as policymakers and NGOs respond to it. Carletto, Zezza, and Banerjee (2013) noted that a consensus on appropriate indicators would benefit the measurement of global food security and the coordination between organizations. Consequently, more research is needed. Such research should not be limited to just measuring the extent of the food security problem but should focus on the causes of food insecurity. 82
