1. Research Areas and
CRPs for CIAT and
CIAT in Asia
Certainly, CASSAVA has a
huge potential to improve
farm productivity for the
livelihoods of smallholder
farmers.
Need
to
develop
appropriate strategies for
cassava sector.

2. Cassava production systems
Dissemination of the
best adopted cassava
varieties and better
agronomy
(including
IPM and soil), to boost
profits as well as yields
while
maintaining
natural resources and
its environment.
Therefore, cassava systems should apply “ReduceRecycle-Reuse” concept in cassava-based systems: ecoefficient agriculture.

3. Our CIAT roles
 Testing/evaluating/
recommendations with
national
partners
(agriculture research
and extension staff)
and local farmers.
 Promoting and advocating best adopted varieties and
agronomic practices (up coming farmers’ cassava
manual).
 Educating about cassava-based crop and livestock
systems and participating in the policy making process.

4. Recommendations: for improved cassava-based
cropping systems options in the specific agro-ecological
location.
 Those recommended
management options
should be technical and
economically feasible,
socially acceptable, and
environmentally
sustainable.
 Building capacity into
research and extension
systems in participatory
ways.

breeders and agronomists to discuss strategies and activities for
“sustainable yield increase”. Possible topics (among others):
– breeding strategies and collaborative work to systematically evaluate varieties
in multi-locational trials

studies)
– (previous, on-going, and planned) soil fertility management trials and
technologies for soil erosion control

cassava-based livelihoods (agronomy, breeding, gender, processing, livestock
feeding)
Implementation Challenges
• Multiple partnerships (coordination, contracts, etc.)
• Develop research for development platforms for scaling-out
• Improving quality of data in on-farm research
• Increasing farmer participation in on-farm research (learning from
farmers)
• Developing technologies with significant impact for up-take
(livestock feeding)

13. SNV-CIAT Project:
Inclusive Business Models to Promote
Sustainable Smallholder Cassava Production (IBC)
• Cambodia, Laos, and Viet Nam
Jan 2013 to Jun 2015
– Cambodia: Kampong Cham (2 companies)
– Laos: Champasak (2 companies), Salavanh (1 company)
– Viet Nam: Quang Binh (2 companies)
• Objective: To develop and promote sustainable production and
business models in which smallholder farmers adopt sustainable
cassava production methods and are integrated into the value
chains of processing enterprises to form profitable long-term
business relationships with increased environmental sustainability
for both production and processing
• Cassava Witches Broom Disease (with CBB) is a serious threat to
livelihoods of smallholder cassava farmers and viability of industries
in Cambodia and southern Laos.

14. Proposed Immediate Interventions
to Address CWBD Crisis at IBC sites in Kampong Cham
and southern Laos (some activities)
-- (1 of 2)
• Farmer/Extensionist Field Days on identification of diseased cassava and
selection and management of planting materials (3 IBC communes in early
Mar 14)
–
–
–
–
Farmers, extensionists, factory representatives, traders
Pictures as posters / handouts to participants
Compare yields from infected and asymptomatic plants (5 each)
Recommendations for destruction of diseased plants, replanting from
asymptomatic plants
• Locate / Verify “clean” planting material (early Mar 14)
– As source for replacement planting (stems) and rapid multiplication (minimal
node cuttings at BU, another facility in Laos ?)
– Sampling & laboratory analysis by EPDP partners (Cambodia, Laos, VN)?
• Replacement Planting (contiguous block) with “clean stems” (3 IBC
communes in Kampong Cham in April/May)
…
