Strategies to use Biofuel Value Chain Potential in Sub-Saharan Africa to respond

to Global Change

Enhancing low-productivity Farming in Tanzania and linking to SMEs

409. June 2010, ICRAF Nairobi

Objectives Better-iS

• To identify the potential for linking low-productivity

farming to small and medium enterprises (SME) to

enhance livelihoods through biofuel value chains

• To provide farmers, regional organizations and local • To provide farmers, regional organizations and local

authorities in sub-Saharan Africa with feasible

strategies

– to benefit from biomass production potential

and

– to mitigate food insecurity.

Survey Area: Tandai Village

(Kinole Ward, Morogoro District)

09. June 2010, ICRAF Nairobi 88

Survey Area: Tandai Village• Location within the

– Uluguru Nature Forest Reserve (UNR)

– Community forest

• Tandai: 1040 households including 4211 individuals

• Sample size 30% (stratified random sampling): 314 households

• Wood value chain (firewood, charcoal, timber..)

• Jatropha as a host plant for spices e.g. black pepper, vanilla, also passion fruit.

Vanilla on Jatropha

What has been done so far:• Survey 314 households on agricultural production patterns and

interlinkages between households• Energy consumption and production • Focus on important value chains of cash crops (banana, pineapple, • Focus on important value chains of cash crops (banana, pineapple,

spices) and agroforestry.• GPS coordinates including altitude of 80% of the households• Timepreferences of the farmer• Perception of soil erosion and yield losses

09. June 2010, ICRAF Nairobi 12

Value chain analysis: Applied methods:

• Development of a social accounting matrix (SAM) extended by natural resource accounts for soil on village levelnatural resource accounts for soil on village level– Impact assessment via multiplier analysis

• Scenario analysis supported by an economy-wide planning model developed for the village economy– Feasibility study comprising different biofuel value chains

• Consumer surveys in selected European countries – Exploring WTP for certified biofuels (and ecosystem services) from Sub-

Saharan Africa

How might Certification Schemes be Designed ?

1. Standard → principles and criteria to guarantee certain characteristics, certain methods etcmethods etc

2. Principles → guidelines describing how to meet a standard

3. Criteria → requirements describing how to achieve the principles

4. Indicators → concrete measures to verify that principles and criteria are met

• How could Co-Benefits between Biofuel production, Carbon savings and other ecosystem services be handled and what kind of market regulation is necessary?

• How could persistent funding and provisioning of ecosystem

• How could persistent funding and provisioning of ecosystem services be secured ?

• What certification scheme is best ?• What are the preferences of consumers and suppliers?
