Stove and fuel
Improved cookstove (natural draft)
Non-traditional, Household, Rocket
Sun-dried hardwood of Acacia species used. Two additional experiments were carried out for each stove using a combination of wood, pigeon pea crop residues, and cattle dung in a 2:1:1 ratio to reflect mixed fuels in their every day usage.
