Abstract
In sub-Saharan Africa, reliance on subsistence-level farming is a significant source of risk since
farmers face protracted periods of drought and the frequent incidence and expanding reach of
diseases and pests. It is likely that such occurrences will be exacerbated by global climate
change, given recent forecasts and scientific findings. One strategy to mitigate these effects is
through the adoption of new technologies. Following the established literature on technology
adoption and productivity, this work is a reassessment of a 2004 AT Uganda farmer-led seed
multiplication and dissemination project for groundnut growers. The major objective of this
research is to determine the lasting impact of the project with respect to the adoption of rosette
resistant varieties of groundnuts (RRVs). Panel data for the 2004 and 2013 growing seasons are
used and include a set of participating farm households (HHs) and non-participating (control)
HHs. The control sample is composed of both a neighboring and a non-neighboring farm group,
which makes it possible to account for spillover effects and selection bias. In order to further
control for possible biases, our identification strategy employs propensity score matching and
instrumental variables methods. In this way, we examine the sustainability and lasting impact of
the original intervention a decade after the fact.
