“…Surprisingly, these figures are by far higher than the finding of [18] which states that Mirchaye and Lakech charcoal stove has the potential to reduce GHG emission by 25% and 11% respectively. Even when compared with the research finding of [41] which studies the fuel-saving potential of Lakech and Mert-Kum firewood stoves in Awassa town. These significant differences might be associated with the types of charcoal fuel and variation in the design of charcoal produced at the different localities of the country.…”

“…This implies that higher time and fuel-saving potentials of locally produced improved stoves have a great contribution for allowing the community to have more time to participate in different socio-economic activities like agriculture, education, etc. Several research findings pinpointed this as improved stove have multidimensional function like providing more time for children and women to participate in education [36], [37], reducing working load, enhancing health benefits [24], reducing the emission of indoor air pollutants [38]- [40], and reducing the impact on forest resources [11], [41], [42].…”

Background: Energy plays an indispensable role in social, and economic development. It is primarily obtained from biomass and converted to required energy using traditional stoves in most developing countries. Currently, the market is dominated by different shapes and sizes of locally produced cooking stoves. Their impact on fuel-saving, and emission reduction, however, has not been exhaustively investigated. Objective and Method: Hence, the objective of this study is to test the fuel efficiency and emission reduction potential of locally produced charcoal stoves. Accordingly, four charcoal stoves and three plant species that are commonly used were collected for conducting laboratory tests following a controlled cooking test. Results: The overall findings revealed that about 62.69% of the respondents use locally produced charcoal stoves compared to the traditional metal stoves (37.31%). However, individual stove-wise analysis indicates that traditional metal stoves are majorly used stove type followed by Lakech (29.36%) and Mirchaye (13.46%) stoves. Overall, a traditional metal stove consumes a huge amount of fuel (0.23ton/year) which is around 0.0046ha of forest and is responsible for the emission of 77.07ton of CO 2 e per year whereas the mean consumption of improved stoves is 0.16ton/year which is about 0.0032ha of forest and emits 13.69tons of CO 2 e per year. Furthermore, these differences were among improved stoves. Accordingly, the highest annual greenhouse gas emission was recorded by Mirchaye stove (14.64ton of CO 2 e) followed by lakech, and kib stoves 13.69, and 12.74ton CO 2 e respectively. The types of wood used for charcoal preparation, in addition to stoves types, also have an impact on the amount of fuel consumed and pollutants emitted. Conclusions: Generally improved stoves significantly contribute to reducing emission and fuel consumption which in turn reduces the impact on forest resources, human health, and global warming of the energy sector. Hence, this finding discloses the distribution of these improved stoves for local communities by government and concerned stakeholders to assure affordable and clean energy for all and reducing pressure on forest and human health.

“…These data, which are consistent with previously published productivity rates (Pohjonen, 1989;Burns & Honkala, 1990;Muchiri et al, 2002;Bekele, 2011;CABI, 2020), indicate the significant benefits that are achieved from CYG and PY quality scenarios compared to the AY baseline (e.g., 73% and 84% for MAI V u and MAI BRA, respectively, for the woodlot production option with the PY quality scenario). The last figure of 84% for branch biomass improvement indicates the fuelwood benefits of the higher quality scenarios, which could substantially support meeting rural households' energy requirements in Ethiopia (Yigezu & Jawo, 2020).…”

“…Globally, energy demand is continuously increasing due to population growth and the need for more energy for domestic and industrial uses [1,2]. Reliably, International Energy Agency (IEA) and other energy sources have forecasted that the demand for energy will increase by approximately 50-65% by the year turn of the year 2040 [3,4].…”

Sub Saharan African (SSA) region rely heavily on fuelwood for their energy needs and will potentially increase in the foreseeable future due to increased population growth in the region. The continued utilization of fuelwood in the region subject to inefficient technology of energy conversion is projected to put more increasing pressure on forest cover and resources. The decline in forest resources is a precursor to exploration of other resources that may provide energy to human, in which agroforestry comes in mind. Therefore, the aim of this discussion paper was to review the status of fuelwood consumption patterns in Kenya, while highlighting the status and sustainability of fuelwood sector in the country. One of the approaches to deal with fuelwood problem is to enhance adoption of agroforestry, with an aim of reducing the harvest of wood and non-wood products in forests through sustainable planting of trees in the farms. However, the main constraints identified in adopting agroforestry for sustainable forest management were: Lack of suitable laws, legislation and policy framework, unavailability of planting material, inadequacy of research and extension services, long gestation time, access to credit, and finally land tenure and security. In order to expand the adoption of agroforestry for sustainable forest resource use, there is a need for logical approach aimed in promoting a multi-purpose agroforestry system under local farming systems where there is still large land capable of sustaining the practice.
