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.
