Abstract

Traditional cooking techniques prevalent contribute to deforestation, indoor air pollution, and associated health issues. This study explores the transformative potential limitations for improved biomass cookstoves (ICS) uptake among the rural households in Kilimanjaro. ICS offer a faster, more efficient cooking process, reducing cooking time, minimizing heat loss, preserving nutrients, fostering healthier eating habits, and enhancing the flavor of meals. Data were gathered from 300 families in two districts through a crosssectional study, employing both quantitative and qualitative analysis, a binary regression analysis model was used to analyze data collected. The findings indicate that firewood is the major cooking fuel source in the region, where preferred by 83.0% of all respondents and 91.70% of population utilize traditional cookstoves while only 13.0% utilize ICS. The results show that income, education level, occupation and awareness of the household head have greater effect on the uptake of ICS, result indicates that the probability of utilize ICS would increase by 63.173 for every unit increase in monthly household income. Furthermore, households with higher education are more likely to utilize ICS technology by 4.579 times higher compared to those with lower education level. Therefore, the study suggests initiating on public campaign to raise the public awareness and encourage the uptake and utilization of improved cookstoves in rural households. The study's insights can guide policymakers, businesses, and stakeholders in promoting realistic cooking solutions, addressing and overcoming financial barriers of energy challenges, and tackling environmental issues in rapidly growth population in Tanzania.
