African Cassava Agronomy Initiative (ACAI):
Taking agronomy to scale in cassava-based systems
in sub-Saharan Africa

Introduction – Tackling the yeild gap
A yield of 30 – 40 t/ha is
attainable in Africa, as has
been shown by well
managed on-farm trials
(Fermont, 2009)
Designated project
countries in Africa
Nigeria, Tanzania, DRC,
Ghana and Uganda

Key Challenges in taking cassava
agronomy to scale
• Inadequate information on cassava growth and nutrient
requirements to develop best agronomic practices,
• lack of site-specific recommendations to reduce the cassava
yield gap based on smallholder farmer resources and
production objectives,
• lack of a decision support framework to interact with partners
and farmers and bring such recommendations to scale
• limited scientific capacity in the NARS
• Ineffective linkage between research and end users of relevant
research products
• Inadequate and haphazard political will for agricultural
development including cassava

ACAI objectives
Reducing the
yield gap
Reducing the
extension
support gap
Generating basic information on
cassava growth and nutrient
requirements to enable the
development of improved agronomic
recommendations
Developing site specific
recommendations based on
smallholder farmer resources
and production objectives
enabling farmers to reduce
cassava yield gaps
Developing a decision support
framework for development
partners interacting with
smallholder cassava farmers that
allows bringing recommendations
to scale
Developing scientific capacity
within the national research
systems by engaging them in
transformative cassava R4D

Implementation framework
Need-oriented approach
(i) Address the cassava agronomy
needs expressed by
development partners as priority
needs,
(ii) project activities will be
embedded in existing
smallholder dissemination
networks,
(iii) the project will facilitate
extension agents to deploy
decision support tools/tools with
direct beneficiaries (mainly
smallholder farmers), and
(iv) an effective ME&L framework
will underpin all the above

Capacity development of national institutions to
engage in transformative cassava agronomy R4D
• Enhanced capacity of national research institutions to conduct
effective cassava agronomy research
• Enhanced capacity of national research institutions to develop
and manage standardized databases
• Enhanced skills of national research institutions in geospatial
data analysis (in coordination with AfSIS)
• Strengthened capacity of national research institutions and
primary development partner organizations in project
management
• Standardized soil and plant analytical laboratories network
including Standard Operating Procedures to support cassava
agronomy

developed and validated
• A cassava fertilizer site-specific recommendation decision support tool for extension agents
developed and validated
• A best planting practice decision support tool for extension agents/farmers developed and
validated
• A cassava intercropping decision support tool for extension agents/farmers developed and
validated
• A staggered planting decision support tool for farmers supplying the processing sector
developed and validated
• A decision support tool advising on best agronomic practices for high root starch content at
harvest for farmers supplying the processing sector developed and validated
• Specific decision support tools and tools developed within the context of cassava value chain
initiatives, managed by partners

ACAI Goal
ACAI will engage over 150,000
households including at least
30% women farmers in the target
countries and lead to the creation
of a value of at least US$ 40
million.
