“…The two reasons are frequently mentioned in Rwanda and other countries as well. This constitutes a serious drawback to the development of biogas as noted by Amigun et al (2012) since people cannot adopt techniques unknown to them. In this context, lack of reliable information on the benefits of biogas and uninformed or poorly informed authorities mean that there is little dissemination about biogas by departments in charge of renewable energy, especially EWSA.…”

“…Biogas is promoted as alternative source of energy because of its multiple advantages. Biogas technology is mastered in Africa since 1950s (Amigun, et al, 2012) and therefore its use should not pose technical problem. It is not only a cheap source of energy and cheap way of handling waste products but also a clean and renewable source of energy.…”

“…In Africa, biogas system is not a new technique as the first biogas plants were installed in 1950s in South Africa and Kenya (Amigun, et al, 2012). In Rwanda, the National Domestic Biogas Programme provides clear guidelines and funding scheme for the construction of biogas digesters in households and institutions (MININFRA, 2011).…”

“…The labor reductions in wood fuel provision are merely shifted to crop residue provision, biogas plant management and effluent return to fields. This challenges the argument of workload reduction often made in favor of biogas production as an alternative to wood fuel [18,19]. The labor data is associated with large uncertainty, and, therefore, the sensitivity analysis has included a range of˘30% labor input.…”

Environmental Assessment of Integrated Food and Cooking Fuel Production for a Village in Ghana

2016

Small-scale farming in Ghana is typically associated with synthetic fertilizer dependence and soil degradation. The farmers often rely on wood fuel for cooking imported from outside the farmland, a practice that is associated with deforestation. Integration of food and energy production may be a holistic approach to solving these issues. We study four approaches to providing food and fuel for cooking in a small-scale farming community. Present practice (PP) of synthetic fertilizer based food production and provision of wood fuel from outside the farming area is compared to three modeled, integrated technology options: integrated food and household-scale biogas production (HH Biogas), integrated food and village-scale biogas production (Village Biogas), and integrated food and wood fuel production (Agroforestry). Integrated approaches are able to eliminate the import of wood fuel, reduce synthetic fertilizer use by 24%, 35% and 44% and soil loss by 15%, 20% and 87%, respectively, compared to present practice. An Emergy Assessment (EmA) shows that integrated approaches are relevant substitutes to present practice considering biophysical efficiency indicated by Unit Emergy Value (in solar emjoules (sej) per J of output) and dependence on renewable inputs indicated by the Global Renewability Fraction (in %): 2.6-3.0ˆ10 5 sej/J and 38%-48% (PP), 2.5-2.8ˆ10 5 sej/J and 41%-46% (HH Biogas), 2.4-2.6ˆ10 5 sej/J and 45%-47% (Village Biogas), 1.7-2.4ˆ10 5 sej/J and 49%-66% (Agroforestry). Systematic recycling and use of local resources may play a pivotal role in reducing the dependence on non-renewable resources in Ghanaian farming, ensuring long-term soil fertility and stemming the current deforestation of wood reserves.

“…According to the UNEP (2010), nearly half of the forest loss in Africa is due to removal of wood fuel. On the other hand, rural women are the ones who are directly affected by the rural energy crisis (Amigun et al, 2012;Smith et al, 2005).…”

This study was conducted to assess socio-economic and environmental benefits of biogas energy and its challenges. The study used descriptive type of research design consisting of quantitative and qualitative research approach. The data collection instruments were household survey, key informants interview and self-observation to collect quantitative and qualitative data types. The study revealed that the biogas installation made each household to save on average 144 min per day from fuel wood collection, cooking, cleaning utensils/kitchen materials) and the reduction in the physical stress was also remarkable. Use of biogas provide an annual saving of 3833.28 Birr from fuel wood, Birr 1243 .20 from charcoal, Birr 128.50 from dung cake and Birr 266 and 717.65 from kerosene and chemical fertilizer, respectively, with net cash flow of Birr 1530 per HH/year. The households encountered lack of skills for adding raw materials to the biogas digester and fertilizer application to their farm land. Training for operation and liquid bio-slurry application is vital for the continuity of the project and revision of feeding material to the digester in different season needs consideration.
