This presentation on lesson learned from YieldWise efforts in the Kenyan Mango Sector was given at the 2nd All Africa Post-Harvest Congress & Exhibition. The focus of the presentation was on understanding how the YieldWise project worked in the context of the mango value chain in Kenya. The YieldWise model was pioneered by the Rockefeller Foundation and deployed in a number of agricultural value chains across Africa, including in tomato, maize, cassava, and mango. The research showed that the YieldWise model enhanced by understanding the shortcomings of its initial deployment is a valid approach. The lead researchers from the University of Maryland and Iowa State University, who prepared the presentation, are making it available via the Consortium for Innovation in Post-Harvest Loss and Food Waste Reduction slideshare account. University of Maryland and Iowa State University are members of the Consortium. The Consortium is funded in part by the Rockefeller Foundation.

5. YieldWise Four Component
Integrated Strategy
TECHNOLOGIES
• Distribution and utilization of loss-reducing technologies
for improving handling, storage and processing of crops
(many of which exist today).
• In some instances, we see opportunities for supporting
targeted breakthrough innovative technologies in specific
value chains (e.g., cold storage).
MARKET DEMAND + LINKAGES
• Linking large anchor buyers demand for fresh and
processed crops to smallholder supply and local
alternative markets to excess crops
• Linkages can include traditional market relationships or
newer procurement and sourcing arrangements.
SHF TRAINING & AGGREGATION
• Aggregation of SHFs into farmer groups is essential to
meet the quantity, quality and consistency of
requirements of buyers
• Capacity-building and other adoption measures are
ther interventions. important to ensure SHFs uptake
technology and o
• Financing will generally be required to facilitate
manufacturing, distribution and acquisition and adoption
of technologies e.g. loans and leasing models.
• Investment capital is also required to fund the scale-up of
promising technologies and innovative distribution
models.

8. Scope of Work
Overall Intent: Discover key factors that foster sustained,
scaled implementation of initiatives to reduce PHL-FW.
Qualitataive research process: 70 Extensive personal
interviews, most F2F
Participants:
Small-holder farmers
Implementing personnel
Traders and other supply chain participants
More than 68 hours of transcribed information
Conducted in early winter 2019
More interviews and analysis to be conducted

9. 10 Findings of Interest
• 3 focused on technology
implementation
• 3 link technology implementation and
other YieldWise components
• 4 emphasize markets and other
YieldWise components

10. Technology Implementation
Key technologies: Fruit fly traps, harvesting tools and tarps
• Effective implementation must provide corresponding
information, knowledge and training
• Farmers are adept at expanding the scope of the
technology’s utilization, beyond intended use
• Reliance on recall-based estimates of loss is
problematic for large scale interventions
11

11. Tech’s Interactions with Other
Components
12
• Effective interventions approach the mango supply
chain as an interdependent combination of “market”
segments
• Expansion of PHL-reducing technology use requires
on-going support which can generate entrepreneurial
action and economic development in rural areas.
• Effective interactions with appropriate government
entities can aid implementation of PHL reducing
interventions

12. Market Interactions with
Other Components
13
• Inefficiencies caused by fragmentation at the trader level
result in lower returns to producers
• Aggregation offers considerable promise, especially with a
primary focus on enhanced supply chain performance
• Especially for perishable commodities, improving the
capacity and effectiveness of downstream market
channels is an important means to reduce PHL.
• Expansion of market uses requires access to applied (R and
D) capabilities

13. Summary Thoughts
14
• YieldWise model, enhanced by learnings from experience,
shown to be valid approach
• PHL-reducing technologies, with support, can provide
value that is recognized by SHFs
• Expanded market use is essential to PHL reduction but
requires access to effective R and D support
• Support and expanded market use are important means to
foster economic development beyond SHF level
