Interdisciplinary Workshop on the Potential of Small-Scale Biogas Digesters in Sub-Saharan Africa

The workshop was organized by Addis Ababa University, the University of Aberdeen, and James Hutton Institute of Scotland on May 16-18, 2011 at Semen Hotel Addis Ababa. Efd Ethiopia research fellow Dr. Zenebe Gebreegziabher presented a paper on the workshop entitled 'Biogas for poverty reduction and climate change mitigation: The case of Ethiopia'.

Biogas for poverty reduction and climate change mitigation: The case of Ethiopia

The paper assesses the role of biogas in redressing the twine challenges of poverty and climate change, in the context of Ethiopia, using farm dataset referring to 2002 (G.C.) production year from stratified sample of 200 farm households in Tigrai, northern Ethiopia, employing simulation technique. We found that biogas reduce poverty by up to ten percentage points depending on the biogas financial benefit and poverty measure used. We also found that biogas technology provides an excellent opportunity for mitigation of greenhouse gas (GHG) emission through (a) methane capture (mitigating emissions from livestock systems) and (b) substituting firewood for cooking, kerosene for lighting and cooking and chemical fertilizers. The reduction in greenhouse gas emission also means substantial amount of money if linked to the clean development mechanism (CDM) or other carbon markets.
