Contrary to persistent perceptions that sub-Saharan Africa is mired in intractable misery, many of the region’s countries have experienced sustained economic growth, deepening democracy, improving governance, and decreasing poverty in recent years.
To take just one aspect of the African Renaissance, in five of six countries for which recent data is available—Malawi, Tanzania, Rwanda, Nigeria, and Ghana—rates of child malnutrition as measured by stunting have declined in the last decade. Because so much is changing in Africa, it is crucial to take this “background” change into account when evaluating the impact of local policy interventions.
This is evident when considering the Millennium Villages Project (MVP) evaluation, which we critiqued in a peer-reviewed journal article. Recently, we examined the three peer-reviewed papers that dealt with the MVP’s impacts and showed that they do not back up the project’s claims of large impacts, in part because they don’t take “background” change into account.
There’s a new development: The MVP has just released its first study that does try to distinguish changes observed at its village sites from broader changes happening across Africa.
