Charcoal Devolution Community-based conservation A B S T R A C T Woodfuels are the most heavily used energy source in sub-Saharan Africa. We analyzed the ecological impacts and modes of access of five user groups (domestic consumers, gin distillers, brick manufacturers, charcoal producers, and tea companies) drawing biomass energy from natural forests in western Uganda. While domestic consumers use the most species for fuelwood (>50), their consumption is likely sustainable because they generally harvest fast-growing species from fallows on their own land or their neighbors'. Charcoal producers prefer old-growth hardwood species and are responsible for the greatest loss of natural forests. They access forests by finding landholders who, either willingly or through coercion, allow trees on their lands to be cleared. The impact of charcoal production is exacerbated by a license system that undervalues natural forests and rewards rapid harvests across large areas. The tea industry consumes mainly eucalyptus wood (Eucalyptus spp.) from corporate plantations, but they indirectly create pressure on natural forests by hiring immigrants who subsequently settle in and clear forest remnants. If such practices continue, forest remnants will soon be exhausted, leaving Kibale National Park as the last natural forest in the region. Forest remnants are a vital source of water, medicinal plants, and energy for local citizens and to protect them from over-exploitation, policy makers should target the charcoal and tea industry for reform. Support for local land management institutions governing access to fallows and successional forests will inevitably enhance the policy interventions.
Household Firewood Consumption and its Dynamics in Kalisizo Sub-County, Central Uganda
This study examined household firewood consumption and its dynamics in Kalisizo sub-county of Rakai district, central Uganda. Fifty households were conveniently selected and administered with semi-structured questionnaires to determine the preferred tree/shrub species for firewood and the socio-economic dynamic of firewood consumption in the households. Direct measurements were made to quantify the daily amount of firewood consumed by the households. Questionnaire responses were analyzed using Statistical Package for Social Sciences (SPSS), while the volume of firewood consumed per household was computed using the formula, V = (πd 2 l)/4. Findings indicated a very strong positive correlation (R 2 = 0.919) between a household family sizes and the volume of firewood consumed per day. On average, a household with a family size of about seven persons consumed 1.56 m 3 of firewood per year. The most preferred tree and shrub species for firewood were Sesbania sesban (85%), Eucalyptus (83%...

Charcoal and firewood contribute to greenhouse gas emissions in rural and urban areas. Although there is information about energy types used for cooking in Kampala urban environment, less is known about the correlates of charcoal and firewood consumption. This study investigated the predictors of charcoal and firewood use for cooking using the 2014 Uganda Census data set. Analysis was conducted on 41,250 households in Kampala City. Multinomial logistic regression model was fitted to predict charcoal and firewood use. Findings indicate that older household heads were more likely to use firewood than their younger counterparts. Charcoal and firewood were more likely to be used in households whose household heads were females, married and formerly married, and lived in dwelling units with two and more rooms. Conversely, chances of using charcoal and firewood decreased with the level of education, living in detached house and flat, and residing in shelter with cement screed or tile/conc...

Around the world, charcoal has persisted as an energy resource and retained unequivocal dominance in the energy consumption mix of some nations many years on since modern alternatives were invented. Furthermore, it has secured unyielding significance as a commodity on local and international markets and remained an aggressive competitor to electricity and gas for cooking. Here, we analyze the charcoal supply chain and highlight the rudimentary production techniques common within the sub-Saharan region, using Uganda as an example. Top global producers, importers, and exporters are discussed and, based on fieldwork from ten locations in Uganda, we describe common trade practices, economic contributions and the realities of charcoal consumption in areas with concentrated grid and electricity coverage. Indeed, forest degradation and deforestation in the charcoal trade is indiscriminate and the world’s top producers and exporters of charcoal do not necessarily have vast forest resources....

Fuelwood scarcity is evident in south western Uganda, where households are using sorghum and maize stalks for cooking as alternatives to the traditional fuelwood. The aim of the study was to assess the implications of fuelwood scarcity on livelihoods of rural communities in Nyarubuye sub-county in Kisoro district in south western Uganda. Systematic random sampling techniques were used to select participating households for the study. Data were collected using direct observation and interviews, using a structured questionnaire that was administered to 80 households in Busengo and Karambi parishes. Face to face interviews were held with key informants, using a checklist. The study showed that the main drivers of fuelwood scarcity in Nyarubuye Sub-county include: land shortage, rapid increase in population, change of land use from communal forested land to crop growing only, lack of integration of trees on farm, inefficient methods of cooking and brick burning. The study also showed that the implications of fuelwood scarcity on livelihoods in the study area were adverse and greatly affected women, as compared to men. They included sickening of eyes, breathing difficulties, snake bites and body dislocations, increased domestic violence (wife beating) and sexual abuse (rape), school attendance inconsistencies for school going children, loss of tree cover and low crop yields. Suggested strategies to reduce fuelwood scarcity in area include: promotion of on farm tree planting activities (agroforestry) and energy saving technologies, availing alternative energy sources such as electricity, enhancing family planning methods, skilling of communities on income generation enterprises especially girls. A byelaw on school children with emphasis on girls to collect firewood during weekends only should be formulated and enforced.
This study investigated an increase in deforestation and its impact in charcoal supply for households in Tanga district (urban). Tanga district was chosen because it has high urban population as compared to her neighbor Districts of Muheza and Mkinga. The district was also chosen because it is so close to natural and reserved forests in both Muheza and Mkinga districts in which effect of deforestation on charcoal supply can be clearly seen and determined. The study involved 61 respondents including (households, charcoal venders and forest officer). Questionnaire survey, interview and documentary review methods were employed in data collection. A quantitative data were analyzed using Statistical Package for Social Sciences (SPSS 20 th version). While qualitative information was analyzed using content analysis. The study findings show that majority 56 (92%) of the respondents reported that there is high rate of deforestation which was mainly contributed by charcoal production in the study area. The study further revealed that the observed high rate of deforestation affect the availability and supply of charcoal for domestic use. The scarcity of charcoal coupled with high and fluctuating price give the evidence on presence domestic energy crisis in the study area. Along with other recommendations, the study recommends that the Government Regulator (Energy and Water Utilities Regulatory Authorities-EWURA) should consider reducing tariff on other sources of energy particularly gas and electricity to allow many people afford and resorting to alternative energies for their domestic use and hence reduce the extent of deforestation.

Wood charcoal (WCH) is a sustainable biofuel for rural and urban users because of its higher energy density and emission of marginal smoke when compared with firewood. Besides helping the poor majority who cannot afford kerosene, electricity or liquid petroleum gas (LPG), WCH is a key source of income and livelihood. This work aimed at quantifying the volume of WCH production as well as appraising its socio-economics, including environmental impacts, especially the impact of long-term deforestation and forest degradation in Africa. Historically robust data from the databases of UN-FAO, FAOSTAT, International Energy Agency (IEA), United Nations Statistics Division, UN-DESA energy statistics yearbook, and the Forest Resources Assessment (FRA) were used. The data analysis involved descriptive statistics, multivariate analysis, and geospatial techniques. The result revealed that East Africa had the highest average wood charcoal production which was 32,058,244 tonnes representing 43.2% o...
Coping with Firewood Scarcity in Soroti District of Eastern Uganda
This study investigated how rural households cope with firewood scarcity in dryland areas of Eastern Uganda. A household survey was conducted in December 2008 to January 2009, where 490 respondents were randomly interviewed. Focus Group Discussions (FGDs) were also held with community elders and women. Responses were analyzed both descriptively and qualitatively. Findings indicated that 99% of the households used firewood for cooking with a per capita consumption of 542.32 Kilograms. Commonly used tree species included Combretnum molle (42.7%) and Acacia polyacantha willd (18.2%). Over 78% of the households have a preference for acacia tree species for firewood. In particular, Acacia polyacantha willd (60.3%), Acacia hockii (16.9%) and Combretum collinum (9.6%) were the most preferred tree species. The scarcity of firewood supply was eminent from the average distance (2 ± 7 Km) traveled by collectors in search of them. Firewood collectors spent 1 to 10 hours with an average of 3 hours weekly in firewood collection activities. This resulted in per annum estimated opportunity cost of Shillings 432,000 (US 232 dollars) for those who collected on weekly basis and Shillings 1,080,000 shillings (US 580 dollars) for those who collected on daily basis. The frequency of collection decreased as distance increased among 89% of the households. Minority of households (1%) have resorted to deliberately planting trees on their own farms to ease problems of firewood shortage, and to modification of biomass stove so as to use less firewood. Households in their endeavour to circumvent the problem of continued scarcity have resorted to poorer quality tree/bushes for firewood (71.2%), alongside other coping strategies such as cooking meals once a day, avoidance of cooking some food types (70%), and using crop residues as fuel source (60%). There is a need for scaling-up on-farm tree planting as well as the use of improved biomass cook stoves in the region.

Consumption of fuelwood contributes to forest degradation and greenhouse gas emissions in developing countries. The aim of the present study was to assess the household energy sources and their contribution to climate change. Multi-stage sampling procedure was employed to select sample households. A total of 152 households with different wealth status were included in the present investigation. Firewood consumption and GHG emission at household level were estimated. Average annual firewood consumption per household was 2781.30 kg (2.78 t). The amount of firewood consumed per household could emit 337.62 kg CO 2 e/yr. Use of improved stove could help to save 1.05 t of firewood and protect 4 × 10 −3 ha of forest degradation per year per household. To reduce the use of biomass as household energy source and its environmental impacts, all stakeholders need to work on awareness creation and provision of alternative household energy sources and improved fuel-saving stoves.
