Exploring lessons from five years of biochar-producing cookstoves in the Kagera region, Tanzania
Biochar-producing cookstoves can supply fuel-efficient heat for cooking in developing countries. The produced biochar can be used as a soil amendment, providing a range of environmental and agronomic benefits and serve to remove carbon dioxide from the atmosphere. Despite these advantages, many stove initiatives have not been sustained in the long term, but very little attention has been devoted to understanding the reasons behind this. The present study contributes to filling this knowledge gap, by identifying key factors affecting the level of stove adoption and use, as well as biochar utilization. Based on a follow-up survey of 50 households in northwestern Tanzania that received microgasifier stoves in 2015, only 12 still made use of their stove 5 years later. One of the main reasons for this relates to the inadequate quality of stove material. Declining or inconsistent availability of feedstocks was also identified as a major challenge. Furthermore, the households generally did not embrace the idea of amending soils with biochar, due to a combination of local practices and perceptions, and a lack of education and awareness programs. We conclude that, under the conditions of the studied project, three factors are required to scale dissemination: improvement of the stove design, provision of training programs on biochar management and subsidies or microloans that would make more durable stoves affordable. Sustained stove deployment can only be achievable by institutionalizing financing structures that are independent from short-term grant-based initiatives. ; Funding: Swedish Research Council for Sustainable Development (Formas) within the National Research Programme on Climate "Visions and Conditions for a Fossil-Free Welfare Society" [2019-01973]; Swedish Research Council (VR) through the Swedish Government [2016-06359]; Sida through the Swedish Government [2016-06359] ; LUNETs
