ARISTIZABAL HERNANDEZ, Javier Darío. Improved cook stoves and fuelwood lots: an alternative of fuel self-supply for small farmers dependent of oak forests in the Colombia eastern cordillera. Colomb. for. [online]. 2010, vol.13, n.2, pp.245-256. ISSN 0120-0739.

In order to improve thermal efficiency of typical cookstoves used in rural area of Encino, Santander, three improved cookstoves prototypes were built, by means of a modification carried out at com bustion chamber. The improved cookstoves were tested by using Controlled Cooking Test ( CCT) and compared against a typical cookstove. Scores displayed a mean performance of 14.66% among im proved cookstoves and typical cookstove, which implies a saving in fuelwood consume of 0.86 ton/year. Likewise, farm fuelwood lots design is proposed by comparing four tree species used for cooking purposes in that place. Finally, impact in terms of avoided deforestation and carbon dioxide emissions is assessed, under a focus that it could integrate both improved cookstoves and farm fue lwood lots.
