Transforming Staple Food Value Chains in Africa: The Case of Teff in Ethiopia

We study changes in the last decade in the teff value chain, Ethiopia's most important staple food crop by area and value. Upstream, there is increasing adoption of modern inputs and new varieties - especially by those farmers living close to cities - leading to higher land productivity. Mid- and downstream, we find improved processing costs and increasing willingness-to-pay for convenience and quality, as illustrated by the emergence of one-stop retail shops and the rise of more expensive teff varieties. Because of the large numbers of teff producers and consumers, this transformation has important implications on the country's food security.
