However, Lappe and Collins's assessment may be correct for countries with predominantly poor rural agricultural economies. The failure of a city-state such as Hong Kong to grow enough to feed its urban population has hunger implications that differ greatly from the failures of predominantly rural African countries whose export earnings are low. For poor agricultural populations, whose entitlements to food may come in large part from home production, their country's deteriorating position of food self-sufficiency may be an indicator of their own reduced access to food and resources to produce food.
