Essential non‐essentials: COVID‐19 policy missteps in Nigeria rooted in persistent myths about African food supply chains

Food supply chains are extremely important for food access and livelihoods across Africa, but their role is often overlooked and underappreciated. Under normal conditions, the gap between myth and reality can result in the design of policies and programs with limited or negative impacts on food security and welfare. The shock of COVID‐19 has heightened this disconnect, with potentially dire consequences for food security.

Rapid transformation of food systems in developing regions: Highlighting the role of agricultural research & innovations

Developing regions' food system has transformed rapidly in the past several decades. The food system is the dendritic cluster of R&D value chains, and the value chains linking input suppliers to farmers, and farmers upstream to wholesalers and processors midstream, to retailers then consumers downstream. We analyze the transformation in terms of these value chains' structure and conduct, and the effects of changes in those on its performance in terms of impacts on consumers and farmers, as well as the efficiency of and waste in the overall chain.

Post-harvest losses in rural-urban value chains: Evidence from Ethiopia

We study post-harvest losses (PHL) in important and rapidly growing rural-urban value chains in Ethiopia. We analyze self-reported PHL from different value chain agents – farmers, wholesale traders, processors, and retailers – based on unique large-scale data sets for two major commercial commodities, the storable staple teff and the perishable liquid milk. PHL in the most prevalent value chain pathways for teff and milk amount to between 2.2 and 3.3 percent and 2.1 and 4.3 percent of total produced quantities, respectively.
