Soil fertility depletion is considered the main biophysical limiting factor to increasing per capita food production for most smallholder farmers in Africa. The adoption and diffusion of sustainable agricultural practices (SAPs), as a way to tackle this impediment, has become an important issue...

This article evaluates the impact of the adoption of improved wheat varieties on food security using a recent nationally-representative dataset of over 2000 farm households in Ethiopia. We adopted endogenous switching regression treatment effects complemented with a binary propensity score...

Since the beginning of 1970’s, more than 40 improved maize varieties have been released and disseminated to maize potential areas in Ethiopia. Using cross-sectional survey data collected in 2011 from 39 districts in five Regional States, this paper examines smallholder farmers’ knowledge,...

The lack of land ownership can discourage agricultural technology adoption, yet there is scarce evidence of the impact of land rental contracts on the adoption of improved crop varieties in developing countries. The current study investigates such impact using a nationally representative survey...

A procedure is developed to examine the ex-post impacts of improved maize varieties on poverty in rural Ethiopia. Yield and cost effects of adoption are estimated econometrically under assumptions of both homogeneous and heterogeneous treatment effects. A backward derivation procedure is...
