The goal for pro-poor mitigation activity, is to develop a low-cost protocol to quantify greenhouse gas emissions and to identify mitigation options for smallholders at whole-farm and landscape levels. Learn more: www.ccafs.cgiar.org

Mariana Rufino 2013: Identifying Pro-Poor Mitigation Options for smallholder agriculture in the developing world
1. Identifying pro-poor mitigation options for
smallholder agriculture in the developing world:
a multi-criteria and across-scales assessment
Mariana Rufino, Todd Rosenstock, Lini Wollenberg, Klaus Butterbach-Bahl
3. The concerns
• Mitigation not linked to livelihoods
• Fragmented and diverse landscapes
• No data on mitigation
• Multi-criteria approaches missing
4. The goal
Develop a low-cost protocol to quantify greenhouse gas
emissions and to identify mitigation options for
smallholders at whole-farm and landscape levels
5. How to identify mitigation options at farm and
landscape level?

18. Step 1. Landscape analysis
Targeting:
- Landscape units, farm types,
field types, soils
- Site selection
Step 2. Installing measurement
stations
Site characterization:
- Soils, crops, biomass
Installation of Informing and
chamber frames interviewing farmers
19. Step 3. Measurements applying
gas pooling
Field work:
- Overcoming spatial variability
by gas pooling method
Gas sampling(closed Storage of gas
Arias-Navarro et al., Soil Biol. Biochem. submitted chamber method) samples in vials
Step 4. Lab analysis and flux
calculations
Determination of trace
Lab work: gas concentrations via
- Analyzing gas samples gas chromatography
- Calculating concentrations and
fluxes

Synthesis of GHG measurements: information useful to derive emission factors,
empirical models, calibrating and validating of detailed models
Upscaling: using the targeting approach (assigning emissions to landscape elements)
and/or of GIS coupled biogeochemical models
