Resumen
Descripción
Countries are increasingly benchmarking food assistance and labour laws on the cost of nationally recommended diets. Benchmarking is made against national annual estimates, which fail to account for sub-national and intra-annual variation in cost, blunting the impact of policies. Using monthly market price data collected by the Government of Rwanda (April 2019-March 2024), we estimate the cost of the country’s proposed food-based dietary guidelines, using a standardised diet costing methodology. We found rural areas experienced greater inflation in diet cost over the study period than urban areas (41% vs 28%), yet the recommended diet was 12.7% higher in urban locations. Diet costs were approximately 6% lower in districts with international border crossings to Tanzania, but 7% more in those with borders with the Democratic Republic of Congo. Fruits and vegetables (110% and 71%) and starchy staples (86% and 83%) contributed most to cost increases in rural and urban locations respectively. Seasonal diet cost fluctuations were also evident with a seasonal amplitude of 5.6% and 6.9% in rural and urban locations, synchronised to Rwanda’s agricultural calendar. 70% of employed Rwandans would find the recommended diet unaffordable, if spending 52% of wages on food. Diet costs varied 4.2-fold across all districts throughout the study period, meaning that uniform national policies to address costs and affordability would be systematically inadequate in high-cost settings and wasteful in low-cost ones. That such spatial–temporal variation exists in a small, relatively market integrated country like Rwanda suggests variation would be at least equally consequential in other low and lower-middle-income countries. High-frequency and sub-national monitoring of prices, diet costs, and affordability provides essential intelligence for policymakers to enable spatially and seasonally targeted interventions, improving both the adequacy and efficiency of food policy.
