Résumé
Energy plays a significant role in a country’s development. Usage of an improved stove that produces biochar could help to reduce the pressure of deforestation, amend soil productivity, and provide cleaner technology for cooking. In Kwale, a county located on the south coast of Kenya, firewood is still used as the primary cooking fuel followed by charcoal. This research aims to investigate the improvements for a Top-litUpDraft (TLUD) biochar-producing gasifier stove, which the users aspired through co-designing. Transformative mixed methods were used as the research design to empower the users’ involvement in the biochar and smallholder farmers in Kenya – improved use efficiency of farm-level organic resources in relation to energy, crops and soil project. Triangulation was used to process the collected data through structured user observations, a focus group discussion, and a semi-structured interview. Between two stakeholders, TLUDgasifier stove users and the manufacturer, there was a difference of opinion for the main priority. Ease of use was the main concern for the users while the manufacturer put forward energy efficiency. Further, the users desired for an increase in the stove’s dimension as its capacity to produce biochar would increase.
