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

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

3

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

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

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

And in fact we do have lots of evidence of these types of barriers being important

10

Barriers Enablers

Low income Extension information Collective action

Labor and capital barriers to adoption

Evidence from Zambia Maize systems

• Yield is higher under MSD in dry areas

• MSD is more capital and labor intensive

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

Improved seed, soil and water conservation and collective

Barriers to income diversification

Barrier Effect

Coefficient of variation of rainfall, 1983-

2010 (+++)

Long term mean rainfall, 1983-2010

(mm) (+++)

Rainfall anomaly, 2009-10 rainy season (- -)

Access to extension service (+++)

Access to Fertilizer subsidy (+++)

Access to safety-net +/-

17

• Coordination between CC & Ag. Planning

• Linking climate and agriculture finance

Enablers II

19

Climate finance

Can represent a significant but small share of overall yearly investment requirements for agricultural growth

27 20

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

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
