Approximately three billion people in Asia, Africa, and the Americas cook with biomass, cleaner cooking technologies with the potential to reduce household air pollution exposure. It is necessary to assess the adoption and long-term use of these stoves, measure perceived benefits among users, and use this information to provide feedback to programs that are implementing new cooking technologies. The aim of this study is to determine the level of adoption and impact of improved biomass cookstoves in the rural area of Lambayeque, Peru, in 2017.
A descriptive cross-sectional study was conducted. A total of 52 homes were surveyed in the districts of Pacora and Íllimo where improved biomass stoves were introduced between 2005 and 2013. A questionnaire for the assessment of adoption and impact indexes proposed by the was applied. The STROBE checklist was used.
The mean number of years with the improved biomass cookstove was 9.1 (standard deviation: 2.9); 51.9% always used the improved stove, and 34.6% never used it due to destruction during the El Niño phenomenon in 2017. The median impact index was 5.62; 19.2% had a very good/good adoption. The median adoption index was 6.5; 25% had a very high/high impact. The use of the traditional or open fire biomass stove persisted in 61.5% of the houses.
The adoption and impact of improved biomass cookstoves were acceptable, but traditional stove use persisted in more than half of the houses. Households used a mix of different stove technologies. Gas stoves were used more frequently for breakfast or dinner, while the traditional biomass stoves were used for larger lunchtime meals.
亚洲、非洲和美洲约有 30 亿人以生物质为炊，清洁烹饪技术有可能减少家庭空气污染。有必要评估这些炉灶的采用情况和长期使用情况，衡量使用者的感知效益，并利用这些信息为正在实施新烹饪技术的方案提供反馈。本研究旨在确定 2017 年秘鲁兰巴耶克农村地区改良生物质炉灶的采用水平和影响。
采用描述性的横断面研究。在帕科拉和伊利莫区共调查了 52 户家庭，这些地区在 2005 年至 2013 年间引入了改良的生物质炉灶。应用了 评估采用和影响指数的问卷，采用了 STROBE 清单。
使用改良生物质炉灶的平均年限为 9.1 年（标准差：2.9）；51.9%的家庭始终使用改良炉灶，而 34.6%的家庭因 2017 年厄尔尼诺现象导致炉灶被毁而从未使用过改良炉灶。影响指数中位数为 5.62；19.2%的家庭采用率非常好/好。采用指数中位数为 6.5；25%的家庭影响非常高/高。传统的生物质炉灶在 61.5%的家庭中仍在使用。
改良生物质炉灶的采用和影响是可以接受的，但传统炉灶的使用在一半以上的家庭中仍然存在。家庭使用了不同的炉灶技术组合。煤气炉更多地用于早餐或晚餐，而传统的生物质炉灶则用于较大的午餐时间用餐。
