“…Furthermore, individuals who have adopted biogas technology have relied on alternative energy sources to support their livelihood. The findings of this study are confirmed by those of [ 40 , 41 ], who found that the majority of families cook and heat using firewood and agricultural leftovers. According to [ 42 ], the annual biomass intake in Ethiopia accounts for 77% of fuelwood which is followed by animal dung and agricultural residue, respectively.…”

“…Almost 1% of the families in the study utilized electricity to illuminate their homes (Figure 4). This conclusion is consistent with that of [40,41], who found that the majority of respondents utilized kerosene lamps and battery cells for illumination, with only a few families using tiny solar panels and biogas.…”

The rapid rate of deforestation, combined with Ethiopia's rapid population growth, has resulted in increased energy scarcity, high greenhouse gas (GHG) emissions, and climate change. Biogas technology has recently been described as one of the most promising solutions to the problems of deforestation, energy supply, and climate change. Therefore, this study was aimed to investigate the potential of biogas technology in fuelwood saving and carbon emission reduction in the Central Rift Valley of Ethiopia. A multi-stage sampling procedure was employed to select a sample of 192 households (HH) (68 biogas adopters and 124 non-adopters). To conduct the Kitchen efficiency test, 25 test subjects were chosen at random from each category. The data were analyzed using descriptive statistics and an independent-sample t-test. The energy source for cooking and heating were fuelwood, biogas, animal dung, agricultural residue, and charcoal were the most common energy source for domestic use, accounting for 46.9%, 35.4%, 9.4 %, 5.2 %, and 3.1%, respectively. Kerosene lamps, battery cells, and tiny solar panels were utilized by 35 %, 32.4 %, and 18 % of respondents, respectively, for lighting. The most widely used woody plants for domestic energy usage were Eucalyptus camaldulensis and Eucalyptus saligna , according to the findings. The digester size of 6m 3 was used in 93 (56.5%) of the 165 biogas plants, while 8m 3 and 10m 3 digesters were used in 69 (43.5%) and 3 (1.8%) of the plants, respectively. Hence, the annual fuelwood savings from using biogas technology per household was calculated to be 1856.78 kg per year, with an annual Carbon dioxide (CO 2 ) emission reduction capacity of 2.75 tons per biogas plant. Consequently, it was projected that all functional biogas plants (111) would save around 305.25 tons of CO 2 e per year. Generally, Biogas has been proven to be a viable technique for reducing reliance on forest resources and mitigating climate change in general. As a result, the country's energy sector should encourage families to embrace biogas technology to enhance fuelwood availability and reduce carbon emissions.

“…This means that the distance from a water supply is an important factor in determining biogas technology adoption. This finding is consistent with prior research that found a negative significant association between distance to the nearest water source and biogas technology adoption (Abadi et al, 2017, Marie et al, 2021.…”

Despite the fact that there have been a large number of biogas plants built in Ethiopia, to what extent the installed plants have contributed to reducing energy expenditure and increasing income has not been empirically examined. Therefore, this study studied factors that influence adoption of biogas technology and effects on rural household energy expenditure in south Ethiopia. Data were collected from 246 sample households, 123 biogas adopters and 123 non-adopters. Simple random and purposive sampling techniques were used to select sample households. For data analysis, propensity Score Matching and Binary logistic regression models were used. The logistic regression results showed that access to credit (p < 0.01), access to electronic media (p < 0.05), and farm size influenced the adoption of biogas technology positively and significantly (p < 0.05), whereas distance to water sources influenced negatively and significantly (p < 0.05). The average treatment of the treated unveiled that biogas technology adoption reduces household annual energy expenditure on average by about 461 Ethiopian currency per year compared to the counterpart. Reduced energy expenditure enhanced household annual income by reducing money spent on fuel purchases. This demonstrates that the deployment of biogas technology improves rural households' energy supply and increases their annual income. To promote and raise knowledge of biogas technology and increase rural energy security and income, government energy offices, policymakers, and development partners should capitalize on variables influencing biogas technology uptake.

Abstract. Ngowi NJ, Ngalawa AA. 2022. Recycling for deforestation reduction in Tanzania: Why are households not using waste charcoal?. Asian J For 7: 1-8. Charcoal making and the subsequent waste charcoal produced to contribute to deforestation and the production of greenhouse gases, the major drivers for climate change. Whereas climate change is increasingly becoming a public issue, Africa produces 63% of the total global wood charcoal. Since 2004, the demand for wood charcoal on the continent has risen by 30%, the highest in the world. The low efficiency of locally made earth kilns, between 8% and 36%, reported in Africa has contributed to increased waste charcoal production on the continent. However, more information is needed on the cycling use of waste charcoal in low-income countries. In order to improve forest resource use, we investigated the factors influencing the cycling use of wood waste charcoal in the Kilosa District of East-Central Tanzania between 2020 and 2021. A total of 298 randomly selected households were involved in the survey. SPSS version 20 tools were used in the analysis through cross-tab descriptive statistics and the independent sample t-test. Results show that sex, age, expenditure on fuel energy, environment, and technology for cooking significantly affected household use of waste charcoal (p < 0.05). The availability of wastes (v = 0.272) was the most influential factor in the cycling use of waste charcoal. The paper shows that cycling the use of wood waste charcoal would reduce volumes of trees cleared for firewood and improve sanitation by removing rampantly disposed waste from the environment.
