A food security indicator for technology impact assessment is needed that can be constructed with available data, is comparable over time and space, and represents the multiple dimensions of food security.
In this chapter, we review some commonly used food security indicators, analyze the extent to which these indicators satisfy key criteria, and introduce a food security indicator constructed for use in an economic impact assessment and that exhibits a number of desirable properties.
This income-based indicator is similar to a consumption-based poverty indicator, utilizing an estimate of the income required to purchase a food “basket” that meets nutritional requirements and comparing the food security income requirement to a household’s per capita income.
The applicability of the indicator is illustrated with an analysis of the impacts of legume inoculation technology developed for smallholder farms in Tanzania and other parts of Africa. We conclude with a discussion of suggested improvements for food security indicators used for technology impact assessment.
