In practice, the best way to monitor food security is to look at outcomes — that is, to count how many people are going hungry. There are two principal measures used in this case, and they are also used as food targets for MDG: (i) proportion of the population undernourished, and (ii) prevalence of underweight children. On either of these measures, a look at the Asia Pacific region presents some disturbing facts. The most comprehensive data on undernourishment are available up to 2005-06, which is prior to the most recent food crisis.
