Three-study comparison of fuelwood or charcoal usage
| Study | Number of household surveys conducted (n) | % of HHs using fuelwood or charcoal | Comment |
|---|---|---|---|
| BAMGa | 24 | 50% | Stove-use monitors indicate that 12/24 HHs used wood during the monitoring period |
| 2015 BUSb | 165 | 28% | 29% of surveyed biodigesters users “regularly used other sources of fuel”, including collected wood (86%), purchased wood (6%), charcoal (6%), and LPG (3%). Dropping LPG users leaves 28% of the total. |
| HIVOSc | 25 | 48% | Around 36% of the biogas households use a wood-fired stove on a daily basis and 48% use a wood-fired stove on a weekly basis. |
