[Stoves] Journal article on household cookstove wood consumption

[Nolbert Muhumuza]

Hello Bryden,

I would be very happy to have a copy of this report.  We are based in
Uganda, we are working on promoting TLUD stoves, and ofcoure fuels. So
it will be helpful in comparing things and learning from this reoport.

Nolbert.

> Abstract -- This study examines the factors that affect fuelwood consumption
> in cookstoves and estimates fuelwood consumption associated with the use of
> cookstoves in a rural isolated West African village with a population of
> 770. Five primary applications of cookstoves were identified: cooking meals,
> heating water for washing, roasting peanuts, making medicine, and steeping
> tea. Six factors were identified that significantly impacted cooking energy
> use: the type of cookstove application, family size, total mass of wet and
> dry ingredients, mass of dry ingredients, the use of burning embers as an
> igniter, and the number of fires used during a cooking event. Annual village
> fuelwood use for all cookstove applications was 234 metric tons; cooking
> meals and heating water accounted for 65% and 27% of this fuelwood use,
> respectively. Fuelwood consumption per person was strongly linked with
> family size. As family size increased from five to twenty members, fuelwood
> consumption decreased from 20.6 MJ cap-1 day-1 to 10.5 MJ cap-1 day-1.

> significance, nonetheless the results are interesting and indicate that
> stove stacking should be considered in our stove programs.
