Abstract

In developing countries, connections between rural households' energy access, efficiency of cooking technologies, and relevant factors are less understood. This study investigates household-level cooking stove's carbon-di-oxide (CO2) emissions, perceptions, and influencing factors in Chittagong, Bangladesh. Methods involve a survey of 176 randomly selected households with a pre-tested questionnaire, and relevant measurements of traditional cooking stoves (TCS) and improved cooking stoves (ICS) of the households in three different categories: nearby, far, and very far from a protected forest area. Results show that most of the households use double-mouthed TCS, although ICS can save 27% fuels and 25% CO2 emissions compared to TCS. Between 44% to 84% of the respondents prefer ICS because these are less labor intensive, emission-friendly as well as fuel- and time- efficient. The perception varies significantly between the households located far away and nearby the park. The amount of fuelwood and total biomass fuels used in the TCS tends to be significantly (p < 0.05) higher than those in the ICS, which corresponds to the higher emissions in TCS. We also find that a household releases six times higher CO2 emissions from burning fuelwood and other biomass fuels compared to use of non-renewable fuels. Households with pucca (brick-built) houses, financial affluency, education, large family size, away from the park, and larger homestead area tend to release more emissions from the use of fuelwood and non-renewable fuels. This study finding can help policymakers make informed decisions in implementing ICS and other cleaner biomass-based projects.

家庭炉灶排放、认知和影响因素:从孟加拉国吉大港Rangunia Upazila获得的经验教训
在发展中国家,人们对农村家庭能源获取、烹饪技术效率和相关因素之间的联系了解较少。本研究调查了孟加拉国吉大港家庭炉灶的二氧化碳(CO2)排放、认知和影响因素。方法包括对176个随机抽取的家庭进行问卷调查,并对这些家庭的传统炉灶(TCS)和改良炉灶(ICS)进行相关测量,这些家庭分别位于离森林保护区近、远和非常远的三个不同类别。结果表明,大多数家庭使用双口TCS,尽管与TCS相比,ICS可以节省27%的燃料和25%的二氧化碳排放。44%到84%的受访者更喜欢ICS,因为ICS的劳动密集程度较低,排放友好,省油省时。距离公园较远的家庭和距离公园较近的家庭之间的感知差异很大。在TCS中使用的薪材和总生物质燃料的数量趋于显著(p <0.05)高于ICS,这对应于TCS更高的排放量。我们还发现,与使用不可再生燃料相比,一个家庭燃烧薪材和其他生物质燃料释放的二氧化碳排放量高出六倍。拥有砖房、经济富裕、受教育程度高、家庭规模大、远离公园、宅基地面积大的家庭,在使用薪材和不可再生燃料时往往会释放出更多的排放物。这一研究发现可以帮助决策者在实施ICS和其他更清洁的生物质项目时做出明智的决定。
