Hunger is often measured by its impact: the rate of undernourishment. A rights-based approach to monitoring the right to food would also look at policies, processes, and outcomes. The World Food Programme’s Voluntary Guidelines to support the progressive realization of the right to adequate food in the context of national food security is a helpful guide; additional handbooks provide concrete advice on how to implement and monitor this right.
The Hunger and Nutrition Commitment Index ranks governments on their political commitment to tackling hunger and under-nutrition. The index is built from 22 indicators focused on laws, programs, and government spending. Data on child underweight rates, wasting, and stunting are available from the WHO’s Global Health Observatory, and disaggregated data related to child nutrition are available through the ICF-Macro’s Demographic and Health Surveys, UNICEF’s Multiple Indicator Cluster Surveys/a> surveys.
