Considerable poverty and food insecurity in Ethiopia, combined with the overwhelming majority of Ethiopians who depend on agriculture for their livelihoods, make agricultural transformation a crucial development goal for the country. One promising improvement is to increase production of teff, the calorie- and nutrient-rich but low-yielding staple. The Economics of Teff: Exploring Ethiopiaís Biggest Cash Crop examines key aspects of teff production, marketing, and consumption, with a focus on opportunities for and challenges to further growth. The authors identify ways to realize teffís potential, including improving productivity and resilience, selecting and scaling up new technologies, establishing distribution systems adapted to different areasí needs, managing labor demand and postharvest operations, and increasing access to larger and more diverse markets. The bookís analysis and policy conclusions should be useful to policy makers, researchers, and others concerned with Ethiopiaís economic development.
