Main outputs of
MAIZE SIs
2. New germplasm
– Disease and pest
resistant variety
– Drought tolerant
– Heat tolerant
3. Crop and resource
management practices
and knowledge
– Minimum or zero
till
– Crop rotations
– Crop residue
retention
– Soil and water
management
– Weed control
– IPM
Outcomes as factors that
determine 1 st order impact
(how, by whom and
assumptions)
NARS partners adapt the
new stress‐tolerant varieties
to local conditions.
NARS extension and NGOs
provide information to
farmers.
Seed companies and farmer
organizations produce seed.
Private sector provides key
inputs.
Men and women farmers
plant new risk reducing
varieties.
NARS partners integrating
better management into
maize cropping systems.
Extension systems unpack
relevant information and
demonstrate best‐bests for
adoption.
Extent of expression in target
environment.
Other value chain actors
package seed, fertilizer and
other inputs and make it
available to farmers.
Farmers adopt new CA‐based
practices along with
improved varieties.
First order impact
(Adopter level changes)
Higher yields in the face of biotic and
abiotic stress.
Area expansion at the farm level.
Increased production.
Reduced vulnerability (risk) from
disease and pest attack.
Increased yields.
Increased farm level production.
Lower per ha level input use (labor,
fossil fuels, fertilizer, pesticides,
irrigation water, etc).
Reduced production costs.
Higher profitability of maize
production.
Diversification of production.
Diversification of diets and nutrition
(crop rotations/intercrops).
Diversification of income sources.
Reduced farm level demand (per
area unit) for water.
Improved soil health (SOM, reduced
erosion, nutrient depletion).
Change in farmer attitudes and gain
in sustainability.
Factors that determine
2nd order impact (how,
by whom and
assumptions)
Increased participation
of seed companies for
production and wider
diffusion of quality
seed of improved
varieties.
Information flow and
knowledge creation
through extension.
.
Farmer participation in
local adaptive trials and
demos.
Provision of finance to
enable investment in
new equipment and
inputs.
Local delivery of key
inputs (fert, CA tools)
by the private sector.
Local manufacturing of
CA tools by artisans.
Scaling out/up of
successful innovations
by government and
NGOs for wider impact.
Second order impact
Reduced vulnerability to
pandemic disease and pest
outbreaks.
Increased food security in
the face of disease and pest
attack.
Reduced inter‐seasonal
maize price fluctuation
(resulting from stability of
production).
Increased adaptation to
climate change.
Improved food security at
farm, national and regional
scale.
Farm level water saving
that may also translate to
basin level sustainability of
water use.
Greater system resilience.
Improved adaptation to
climate change.
Soil carbon sequestration
and reduced emission of
green house gases
(mitigation of climate
change).
Improved air quality from
reduced burning of crop
residues.
