QPM in Uganda
Can QPM Contribute to Achieve the
Malabo Food Security Target in
Uganda by 2025?
What has been done so far
1. Yield trend analyses: Maize yield gap and trend analysis for Malabo target; as
well as ex-ante bio-economic analyses for the technology’s potential
contribution to the Malabo goal (2016 & 2017)
2. Identification of commodity priority areas: Identifying the maize intervention
area (hotspot) in Uganda (e.g., high potential, large gaps in yield and nutrition)
(2016)
3. Technology profiling: Profile a potential technology suitable for the hotspot
area (2016)
4. Adoption studies: KI & Focus group interviews to assess current and target
adoption levels (2017; On going)

 Desk review
 KI informant panel survey
 K Shift
• Vertical shift of the supply function
expressed as a proportion of the
initial price
• Shift in supply curve due to research
and is equivalent to the ratio of the
yield from high yielding variety to that
from conventional varieties
 Dream runs to determine Total
R&D benefits (GARB)
• Data fitted in the DREAM model
• NPV values generated

Approach and Methodology (2)
Total Benefits (B) computed from the following formula:
B= PQK (1 + K*0.5ED) (1- [(1-ED)2 ES/(ED-ES)]
Where B= Gross Annual Research Benefits (GARB); P= Price of the Product;
Q=Quantity of Product; K= Shift of the supply curve due to research; and ES and
ED are the supply and demand elasticities respectively
Kmax due to induced R&D effects is computed from the formula
Ki
Max = PiciAi
Max PPi,0 > 0
Where Pi= Probability of success which if the research is successful and the
products are fully adopted; will yield a cost saving per unit of output equal to ci
percent of the initial price PPi,0 in region i; while a ceiling adoption rate of Ai Max
percent holds in region i

Conclusions
 QPM if fully adopted in Uganda has the potential to address the current yield
gaps in maize production and contribute to the delivery of Malabo targets
 Investment in QPM production is beneficial as shown by the NPV values.
 Govt of Uganda through the national extension system should invest in
promotion in the adoption of the QPM technology
 Both public and private sector institutions should be engaged in the delivery
system for the QPM technology for wider impacts
Next steps
 Collect more adoption data from sampled regions
 Feed the input data into the DREAM model
 Develop a technical brief
 Validate the findings with stakeholders (MAAIF)
Phase II: Integrated Modeling Analysis & Publication
May–Dec2017
 Quantitative data collection
 Analytically assess technology
benefits using an integrated
modeling framework
 Spatially analyze spillover and
price effects using a market
