A Vision for Climate Smart
Agriculture
Bruce Campbell, Director
CGIAR Program on Climate Change, Agriculture and Food Security
(CCAFS)
1. What is CSA?
2. Mitigation options
3. Adaptation options

• Positive on CSA: national governments,
regional organisations, regional farmer’s
organisations
• Informal feedback: More clarity needed on
CSA
A multitude of trade-offs……..
• Across sub-sectors (e.g. residues to soils or
livestock?)
• Across spatial scales (e.g. more productive
agriculture can result in forest clearance)
• Different kinds of households (e.g. some risk
insurance exclude female-headed households)
• Short-term vs. long term benefits (e.g.
livestock risk insurance can promote land
degradation)
CSA will differ significantly…

2) Mitigation
options
Where to invest?
GHG reduction
Cropland management
Land cover change
Manure-biosolid
management
Bioeenergy
Livestock management
Restoration of degraded lands
Management of organic
soils
Grazing land management
• Agronomy
• Nutrient management
• Tillage/residue management
• Water management
• Rice management
• Agro-forestry
• Set-aside, land use change
Five areas for investment
1. Sustainable intensification &
forest governance
2. Sustainable land management
(SLM) practices
3. Alternate wetting and drying
systems in irrigated rice
4. Improved nitrogen use
efficiency
5. Increased intensity of ruminant
production in Africa to reduce
GHG++ per unit of product

Key adaptation strategies Incremental adaptation to progressive
climate change
• Closing the yield gaps
• Raising the bar – breeding for 2030s
Climate risk management
• Technologies (e.g. flood-resistant varieties)
• Institutions (e.g. index-based insurance)
• Climate information systems (e.g. seasonal forecasts)
Transformative adaptation
• Changing production systems
• Changing livelihood portfolios
Mali farmer climate advisories
• Climate information to farmers for decision
making
• National Met Service, WMO, ACMAD
• Forecasts provided for three‐days, ten‐days,
and seasonal (inc. crop health...)
• Major increases in yields for participating
farmers
• Lessons learning and scaling up across Sahel?
EA Regional Learning
partnership • Information exchange, capacity strengthening, building
consensus around issues and priorities
• =
• National and regional
agencies
• Research providers
• NGOs & policy think tanks
• Regional economic
community
• Advisory services
• Farmer organisations
Activities
• Common messages
to UNFCCC COP17
• Communities of
practice
– Synergies across
diverse projects
– Carbon markets for
agriculture

Transformative adaptation
Relocation of grape
production or wineries to
cooler regions
Shifts to other crops
Diversification

4) Which way forward for CSA?
CSA, in summary:
• Takes into account: food security, adaptation and
ecological footprint
• foremost about development itself and address
smallholder concerns
• Crucial to deal with trade-offs
• Context matters: CSA differs widely
• Development & ecological footprint → green economy
What is needed?
• Analytics and tools – choices, options,
investments
• What kinds of knowledge products are
needed to advance action
– especially at farmer, district and national
levels?
– but also for coherent messaging and
dialogue?
More analytics on resource
efficiency? E.g.

X Rice

Questions
• What kinds of knowledge products are
needed to maintain momentum?
• Is it time to give more formalisation to the
partnership between the CGIAR and WB?
