2. Outline of the presentation
• Barriers to adopting what?
• Changing weather patterns means farmers need to adapt
• Though CSA is a site specific concept, there are key features of
what it will take & specific barriers associated with them
• Policy levers to reduce barriers
• Policy coordination and financing needs
2
3. Barriers to what?
• Changing agricultural production systems
– Increase productivity, incomes, reduce variability and
environmental damage
– Covers a wide range of possible options/combinations
• But goes beyond agricultural practices
– Income diversification
– Efficient charcoal production
– Value chain management

4. Just to get an idea of the variation in agricultural practice
sets farmers could adopt – evidence from Malawi

8. II. Although CSA benefits & costs are site
specific – we can identify some universal
characteristics of CSA practices and
technologies
… as well as the barriers to their adoption
8
9. CSA characteristic Examples and means Potential barriers
Resource use efficiency Correct timing & dose
of inputs
Input recommendations
for heterogeneous
conditions
Timely delivery of inputs
Extension packages designed
for specific agro-ecologies
Increased resilience of agro-
ecosystem
Improved water holding
& drainage capacity;
Delay/time frame to build
ecosystem services results in
financing gap
Labor constraints
Coordination across
landscapes
Protect watersheds
through tree planting
Restore degraded lands
through grazing mgmt
Lack of social organizations to
manage collective action
9
10. And in fact we do have lots of evidence of these
types of barriers being important

Evidence from Zambia Maize systems
• Yield is higher under MSD in dry areas
• MSD is more capital and labor intensive

15. Enablers 1
• Information (e.g. via extension, radio) but
needs to be more effective esp for poor
• Input supply (timely and amount --- input
subsidy program design – agro-dealers)
• Participating in organizations
• Safety nets /insurance

Rainfall anomaly, 2009-10 rainy season (- -)
Access to extension service (+++)
Access to Fertilizer subsidy (+++)
Access to safety-net +/-
17
18. • Coordination between CC & Ag. Planning
• Linking climate and agriculture finance
Enablers II

20. Climate finance
Can represent a significant but small share of overall yearly
investment requirements for agricultural growth
27 20
21. Summing up II
- Weather variability is key determinant of
which practices will give yield, stability and
income increases
- We already know a lot about the
characteristics of the practices we need for
CSA & the types of practices that can generate
them under some condition
21
22. Summing up II
• We also have a pretty good idea of which levers are key, but
need more info on how to best operate them
• We need to look beyond changing ag. Practice for CSA, but
in many cases we will be dealing with the same levers
• The scale & urgency of transformation needed indicates the
need for enhanced (e.g. coordinated) policy & financing
response
