摘要：In many Sub-Saharan African countries, fuelwood collection is among the most significant driver of forest degradation. There are few studies on improved cookstove emissions and fuel use performance in Ethiopia. Therefore, the objectives of this study were evaluating the specific fuel performance of the improved cookstove and impact of improved cookstove on fuelwood consumption and CO2 emission in Megech Watershed. For data collection, both experimental and survey designs were employed. For household survey a total of 385 households were selected for interview using multistage sampling and 10 control coking test trials were performed using Mirt stove and traditional three stone open fire for injera baking. The result revealed significant difference (t = -13.658; p = 0.0001) was seen between ICS (improved cookstove) and three stone open fire on the controlled coking test experiments. The use of Mirt stove under field conditions was saving 35.56% of fuelwood for injera baking in Megech Watershed. Generally, the ICS have dual purpose of saving fuelwood and mitigating forest degradation by saving 10071.04 tons of CO2 per year. Therefore, Mirt stove are an effective and efficient contribution to securing carbon storage in forests. The contribution of ICS to the reduction of CO2 emission, forest degradation and household workload can be improved by increasing the capacity of the households to use the ICS. Finally further study should be done particularly stove performance experiment at different seasons.
