Introduction
To harness the untapped potential for the poor, the International
Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in
collaboration with national partners developed and released
severalhigh-yieldingandstress-tolerantvarietiesofpigeonpeaand
chickpeawithdesirableagronomicandmarkettraits. Assessingthe
impact of these varieties can assist with setting priorities,providing
feedbacktoresearchprogramsandguidingpolicymakersandthose
involved in technology transfer to have a better understanding of
the way new technologies are assimilated and diffused into farming
communities.
Capturing Impact of Improved Pigeonpea
and Chickpea on Rural Households in
Tanzania and Ethiopia
Farm-level effect of improved varieties
Objective
To provide rigorous empirical evidence on the role of adoption of
improvedchickpeaandpigeonpeatechnologyonhouseholdwelfare
outcomesusinghouseholdsurveydatafromarandomcross-section
sample of 1313 small-scale producers (700 in Ethiopia and 613 in
Tanzania).
· The mean value of crop income per capita of adopters is
significantly higher than non-adopters.
· Improved pigeonpea adoption increases crop income per capita
by about 109% whereas improved chickpea adoption increases
crop income per capita by about 37%.
· For non-adopters, the mean crop income per capita would have
been increased by 44% had they adopted improved pigeonpea
and by 19% had they adopted improved chickpea varieties.
· Results also confirm that adoption of improved pigeonpea and
chickpea technologies has a positive impact on consumption
expenditure per capita.
· The mean consumption expenditure per capita of improved
pigeonpea and chickpea adopters is 74% and 25% higher than
those who had not adopted improved varieties respectively.
· If non-adopters had adopted improved pigeonpea, their
consumption expenditure per capita would have increased by
70%, whereas for chickpea it is about 18%.
· These results imply that adoption of improved agricultural
technologies increased household welfare measured in terms of
crop income and consumption expenditure.
