Kassie, Menale, Mahmud Yesuf, Gunnar Köhlin, John Pender and Elias Mulugeta. 2008. “The Role of Soil Conservation on Mean Crop Yield and Variance of Yield: Evidence from the Ethiopian Highlands.” EfD Discussion Paper 08.
Stone bunds in the Ethiopian highlands showed statistically significant and positive impact on yield in low-rainfall areas, but not in high-rainfall areas, and they did not have a statistically significant impact on production risk in either area.
Stone bund performance varied by agro-ecology type, which implies the need for appropriate technologies that enhance productivity and are better adapted to local conditions.
