政策、实践和学术界普遍认为，采用现代烹饪方法可以使撒哈拉以南非洲受益。许多研究探讨了影响清洁烹饪选择的各种人口、社会经济和体制因素。然而，大多数此类研究没有适当考虑地理和环境因素以及燃料可用性如何影响炉灶的采用。在本研究中，我们使用基于样线的方法，从薪材丰富的地区（国有森林）到薪材稀缺的地区（穆兰加县的半干旱内陆地区）和有多种燃料选择的城郊地区（Kiambu 县的城郊地区）。我们对肯尼亚全国人口普查中使用的查点区的两条样带随机选择的 400 个家庭进行了调查，以了解各种因素如何交叉影响采用改进的生物质炉灶作为主要炉灶。概率分析表明，炉灶的采用不仅取决于人口和社会经济因素（例如收入、教育），还取决于反映生物质可用性和可及性以及市场准入的地理和环境因素。女性户主家庭采用改良生物质炉灶的比例往往较低，这主要是由于收入较低和相关有利因素（例如教育、土地面积）。通过路径分析，我们发现这些家庭可以通过更好地获得信贷服务和参与社会团体来增加采用改良生物质炉灶的机会。总体而言，这项研究表明，需要根据薪材的可用性和可及性以及市场准入考虑因素，制定不统一且空间明确的炉灶推广策略。这种考虑当地情况的策略可以促进肯尼亚和非洲大陆其他地方大规模采用清洁烹饪方案。
There is a wide consensus within policy, practice, and academic circles that the adoption of modern cooking options can benefit sub-Saharan Africa. Numerous studies have examined the various demographic, socioeconomic and institutional factors affecting the adoption of clean cooking options. However, most such studies did not properly consider how geographic and environmental factors and fuel availability can affect stove adoption. In this study we use a transect-based approach, from an area of high fuelwood abundance (a state forest) to an area of high fuelwood scarcity (the semi-arid interior of Muranga county) and a peri-urban area with many fuel options (the peri-urban area of Kiambu county). We survey 400 randomly selected households along the two transects from enumeration areas used in the Kenyan national census to understand how factors intersect to affect the adoption of improved biomass stoves as primary stoves. A probit analysis suggests that stove adoption depends not only on demographic and socioeconomic factors (e.g., income, education), but also on geographical and environmental factors that reflect biomass availability and accessibility, and market access. Female-headed households tend to have lower rates of improved biomass stove adoption, largely due to lower income and related enabling factors (e.g., education, land size). Through path analysis we identify that such households can improve their opportunities to adopt improved biomass stoves through better access to credit services and participation in social groups. Overall, this study suggests the need for non-uniform and spatially explicit stove promotion strategies informed by fuelwood availability and accessibility, and market access considerations. Such strategies that are conscious of local contexts could catalyze the large-scale adoption of clean cooking options in Kenya, and elsewhere on the continent.
