Introduction Relevance of domestic biogas for development PPRE Oldenburg University biogas compact course April 26 – 28, 2011 Presenters Biogas Practice Area Dr. Henri Spanjers Based in Wageningen, The Netherlands. Project Director with Lettinga Associates Foundation (LeAF) at Wageningen University. email: [email protected] Willem Boers Based in Addis Abeba, Ethiopia. Advisor to the Ethiopia National Domestic Biogas Programme and RE advisor for SNV. email: [email protected] Steven von Eye Based in Groningen, the Netherlands. Energy Analyst for the Energy Delta Institute email: [email protected] Felix ter Heegde Based in Nairobi, Kenya. Regional biogas / RE advisor for SNV email: [email protected] Domestic biogas • Large scale dissemination of household bio-digesters; • Minimum daily feeding 20kg of animal dung (cattle, buffalos, pigs, chicken) possibly with a toilet attachment, maximum feeding about 200kg; • Replacing about 5kg of firewood, 1.5 kg of charcoal or 0.6litre of kerosene per 25kg dung/day; • Investment cost in Asia between US$ 350 and 800. In Africa considerably more expensive. Biogas Practice Area Biogas: energy … • Over 2 billion people worldwide lack access to clean, safe and sustainable domestic energy services. • Lack of access to adequate, affordable, reliable, safe and environmentally benign energy is a severe constraint on development. • A lack of access to clean and affordable energy can be considered a core dimension of poverty. Biogas Practice Area and so much more … : Biogas Practice Area MDG & domestic biogas I Biogas Practice Area MDG 1 Eradicate extreme poverty and hunger Target 1 To halve extreme poverty – Construction and installation of biogas creates employment for landless rural people. – Biogas saving on the use of traditional cooking fuels increases the availability of these fuels for (very) poor members of the community. MDG 3 Promote gender equality and empower women Target 4 Eliminate gender disparity in education. – Domestic biogas reduces the workload –collection of firewood, tending the fire, cleaning soot of cooking utensils - with 2 to 3 hours per household per day. – Biogas illumination is highly appreciated for lighting, facilitating reading / education / economic activities during the evening. MDG & domestic biogas II MDG 6 Combat HIV/AIDS, malaria and other diseases Target 8 Halt/reverse incidence of malaria and other diseases. • Biogas substitutes conventional energy sources, virtually eliminating indoor smoke pollution and, hence, the related health risks (e.g. respiratory diseases, eye ailments, burning accidents). • Biogas greatly reduces the workload involved in the collection of traditional cooking fuels like wood. Biogas Practice Area MDG & domestic biogas III • Biogas significantly improves the sanitary condition of farm yard and its immediate surrounding, lowering the exposure of household members to harmful infections generally related with polluted water and poor sanitation. • Proper application of bio-slurry will improve agricultural production (e.g. vegetable gardening), thus contributing to food security for the community. Biogas Practice Area MDG & domestic biogas IV MDG 7 Ensure environmental sustainability Target 9 Integrate the principles of sustainable development into country policies and programmes and reverse the loss of environmental resources. • Particularly larger biogas dissemination programmes have a considerable governance component. As such, they positively influence national policies on sustainable development (e.g. agriculture, forestation) as well as promote participatory governance involving women and other disadvantaged groups. Biogas Practice Area MDG & domestic biogas V Biogas Practice Area MDG 7 Ensure environmental sustainability Target 10 Halve the proportion of people without sustainable access to safe drinking water and basic sanitation. • Biogas reduces fresh water pollution as a result of improved management of dung. Connection of the toilet to the biogas plant significantly improves the farmyard sanitary condition. Development at different levels • • • • Biogas Practice Area Farmers; Craftsmen, engineers and maintenance workers; Governments; International Community.
