One of the most common assumptions underlying current policy and development interventions in Sub-Saharan Africa is that the use of all modern agricultural inputs – like chemical fertilizer, improved seed varieties, irrigation, agro-chemicals, and machinery – remains dismally low. But when you examine the evidence underlying this basic claim, it’s easy to feel misled. Most of the well-perpetuated numbers we hear about are from highly aggregated macro-data sources while others are derived from small or purposively chosen samples. Even further, many of the studies that continue to be cited are a decade or two old and may no longer be accurate in an environment influenced by pledges made via the Abuja Declaration on fertilizer.
So what’s a policy analyst to do when the evidence base is likely problematic? Just wish and hope that more appropriate data existed? For a set of eight countries in Sub-Saharan Africa, the wait is over. The Living Standards Measurement Study Integrated Surveys on Agriculture now provide nationally representative and highly disaggregated data from farmers’ agricultural plots to help rebase our understanding of African agriculture and rural spaces.
