Transforming Staple Food Value Chains in Africa: The Case of Teff in Ethiopia
研究了近十年埃塞俄比亚最重要的主食作物苔麸价值链的变化，上游农民采用现代投入品和新品种提高土地生产率，中下游加工成本降低、消费者对便利和品质的支付意愿上升，对粮食安全有重要影响。
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.
