For many regions around the world, geographic isolation is the primary cause of seasonal fluctuations in the price and availability of foodgrain. To activate the local food market, dampen such fluctuations, and improve people’s nutritional status, Burkina Faso’s Food Security Granaries programme set up village-level cooperatives and put them in charge of buying grain from outside sources and selling it locally. This column assesses the effects of the intervention and finds that market activation considerably reduced nutritional stress, especially among young children. The nutritional improvement is driven by a change in the timing of food purchase and hence, of consumption.

Different survey methodologies are typically employed to produce estimates of global hunger. This column considers some of the methodological issues that arise. Short reference periods for each household lead to overstated variances and the confounding of chronic and transient welfare components. The column goes on to present a new approach to measuring chronic hunger which tackles this sampling problem by employing an intra-year panel.
