While starvation is mostly the consequence of structural poverty and deficient
infrastructures (roads, access to water, communication systems…) combined with more or
less important entitlement shocks, only major disasters (Tsunami, earthquakes, droughts or
floods) or conflicts are highlighted. The reason for that is twofold: catastrophes have an
incredible positive impact on audience ratings and it is extremely difficult to locate those who
suffer the most and explain or understand the reasons for such situation. Even specialized
agencies are not able to accurately and precisely detect food insecurity in space and time. But
they are not to be blamed. Indeed, potential food insecure populations cover huge territories
and represent billions of people in the developing countries. Moreover, in spite of the fact that
anybody naturally understands what hunger means, there is no “gold standard” measure for
food security (Maxwell et al. 1999).
