Abstract
The paper evaluates the impact of adoption of pushpull technology (PPT) on household welfare in terms of productivity, incomes and poverty status measured through percapita food consumption in eastern Uganda. Push-pull is a
habitat management strategy for the integrated management
of stemborers, striga weeds and poor soil fertility involving
the use of a natural repellent (push) and an attractant (pull).
This biological technology simultaneously reduces the impact
of three major production constraints to cereal-livestock farming in Africa − pests, weeds and poor soil. Cross sectional
survey data were collected from 560 households in four districts in the region (Busia, Tororo, Bugiri and Pallisa), in
November and December 2014. Generalized propensity scoring (GPS) was used to determine the intensity of adoption of
the technology (i.e., land area allocated to PPT) and also to
estimate the dose-response function (DRF) relating intensity
of adoption and household welfare. Results revealed that with
increased intensity of reported adoption of PPT, the probability of being poor declined through increased maize yield per
unit area, incomes, and per capita food consumption.
However, its impact varied with the intensity of adoption.
With an increase in the area allocated to PPT from 0.025 to
1 acre, average maize yield per unit area increased from 27 kg
to 1400 kg, average household income increased from 135
US$ (Uganda Shilling (USh) 370,000) to 273 US$ (USh
750,000) and per capita food consumption increased from
15 US$ (USh 40,000) to 27 US$ (USh 75,000). The average
probability of a household being poor (below a rural poverty
line of US$ 12.71) declined from 48% to 28%. These findings
imply that increased investment in the dissemination and expansion of PPT is essential for poverty reduction among
smallholder farmers in Uganda.
