Table 1 Description of data and data sources for biomass fuels consumption
From: Environmental and economic accounting for biomass energy in Ethiopia
Notation | Data type | Source | Description of data | Notes |
|---|---|---|---|---|
EUEI | Biomass fuels consumption | [12] | Consumption of firewood, charcoal, residues, and dung by users (in tons) in 2013 | Adjustments are made to 2015 assuming 1% annual growth rate [11]. The consumption in services sector is the difference between the total and households’ consumption |
MoWIE | Biomass fuels consumption | [7] | Consumption of firewood, charcoal, and agricultural wastes by users (in terajoules) in 2015/2016 | The value for agricultural wastes is equally divided into crop residues and dung following the average proportion from [12, 30]. The energy values (in terajoules) are converted to mass units (in tons) for easier calculation of the economic values |
AFREC | Biomass fuels consumption | [34] | Consumption of firewood, charcoal, and agricultural wastes by users (in tons) in 2015 | The value for agricultural wastes is equally divided between crop residues and dung using the average proportion from [12, 30] |
COMB | Biomass fuels consumption | [11] | The consumption of firewood (in cubic meters) and charcoal (in tons) in 2013 | The firewood consumption in 2013 (= 110.644 million m3) is adjusted to the year 2015 assuming 1% annual growth rate [11]. The value is converted to tons using the rate of 0.6 t/m3 [10]. Two percent of the total firewood consumption is allocated to services based on shares from [7, 12, 34]. Charcoal use in industries is taken as charcoal use in services |
COMB | Biomass fuels consumption | [30] | Estimated harvested area and output per crop (as potential resource for residues) and cattle population (as potential resource for dung) by smallholder farmers in 2015/2016 | The potential supply for agricultural wastes is calculated based on crop production and cattle population [30] which is later adjusted using relevant coefficients from the literature (e.g., [13, 18, 35–37]) to arrive at the actual consumption |
