At the 1996 World Food Summit, 186 countries made a commitment to reduce th
e number of chronically undernourished people by half by 2015. In order to
formulate effective policies for reaching this goal, a thorough understandi
ng of the location and causes of food insecurity is needed. This paper prov
ides a broad overview of the current character of food insecurity in develo
ping countries, focusing on two questions: (1) Why are they food insecure?
and (2) Why are the food insecure? To answer the latter question data from
58 developing countries with high prevalences of food insecurity are employ
ed to examine the relative importance of two of food insecurity's most basi
c causes: national food availability and the inability of people to access
food due to poverty. Using child malnutrition as a proxy (along with descri
ptive controls for non-food determinants of malnutrition). the paper finds
little correlation between national food availabilities and food insecurity
. The group of countries that exhibit the highest severity of food insecuri
ty are those with high poverty and food (dietary energy) surpluses, consist
ent with the view that poverty is the most widespread cause of food insecur
ity in the 1990s. The paper concludes by considering the implications of th
e analysis for appropriate geographical and policy targeting to improve foo
d security for the greatest numbers of people at the fastest pace, now and
into the 21st century. (C) 2000 Elsevier Science B.V. All rights reserved.
