Abstract BackgroundBiomass is the most dominant source of energy for both food cooking and lighting in rural parts of Ethiopia. Energy conversions are carried out in open fires using inefficient traditional stoves, results in poor quality of life due to smoking-related health outcomes, and consume a large quantity of wood. This resulted in increased costs of health and cutting trees which facilities climate change. To change the situation, improved cooking stoves (ICS) have been introduced through youth cooperatives in the study area.Objective The study examined the major sources of energy for the rural households, evaluate the health and related benefits of using improved cook stove and assessing the determinants for its adoption.MethodData were collected from 344 households using a questionnaire in supplement with interview schedule. The collected data were analyzed using both descriptive and econometric models.ResultsThe findings of the study showed that only 22.97% of the respondents adopted the ICS whereas the vast majority (67.03%) still rely on traditional stoves that are highly inefficient. The positive and significant variables in predicting the adoption of ICS were the educational level of household head (OR 1.23; CI at 95% 0.029-0.040), access to ICS (OR 5.88; CI at 95% 1.05-2.48), affordability (OR 2.31; CI at 95% 0.11-1.56) and demonstration about the stove (OR 6.74; CI at 95% 1.13-2.68). Family size (OR 0.74; CI at 95% -0.45-0.12) and Availability of firewood (OR 0.27; CI at 95% -2.00-.56) significantly and negatively affected the adoption of the ICS.ConclusionsLow adoption levels of ICS were found in the study area. This has been triggered by socio-economic, institutional, financial, and resource endowments. Therefore, it is recommended that increasing access to improved stoves, diversifying income sources, creating awareness about ICS health benefits, climate changes, and providing reasonable prices will facilitate its adoption.

Abstract Traditional biomass-burning stoves are used for cooking and heating across the globe. These stoves generate smoke that results in household air pollution, which poses a significant risk to human health. In the past decades, there have been many efforts to promote the adoption of improved cookstove designs, but uptake of improved stoves is often slow due to high costs, inconsistent supply chains, and incompatibility with local cooking practices. This paper presents survey results from rural villages in Uttarakhand, India regarding routines and attitudes on cooking and space heating. Significant findings include the dual use of liquified petroleum gas and biomass fuels, the interconnected and seasonal nature of cooking and space heating, the cultural significance of traditional cookstoves, and the prominence of locally available materials in cookstove construction and maintenance. Comparisons of these surveys’ findings to previous investigations on energy use in the Himalayan region show many common trends, but also reveal regional differences. The paper concludes that due to the significance of culture and context in cookstove design, understanding user needs and behaviors and working with local communities are integral parts the design methodology for clean cookstoves. These results provide a case study which agrees with existing literature on the importance of participatory design in global development.

Set against the United Nations Sustainable Development Goal 7, and the need to increase biomass Improved Cookstove (ICS) adoption and sustained use across the globe, this paper presents an evaluation of Practical Action Nepal’s (PAN) Results Based Financing for Improved Cookstove Market Development in Nepal (RBF) project, which was conducted between January and April 2020. Nepal has a long history of International Development assistance, yet 65.8% of rural households still use firewood as their primary source of energy. With this in mind we aimed to understand the barriers, enablers and engagement strategies for the adoption and sustained use of Improved Cookstoves (ICS), map key stakeholder role perceptions and interactions, and identify areas for improvement to increase the sustained use of ICS in the focus communities. This paper uses the methodological approach from the qualitative Technology Implementation Model for Energy (TIME) for the data collection and analysis elements. Our core results show a direct need for improved communication between all key stakeholder groups, the impact of demand and supply side financial incentives in creating reputational risk for community-based key stakeholders, and how the RBF mechanism promotes initial end-user adoption but not sustained use of ICS due to a focus on immediate results.

Abstract Introduction Cooking- and cookstove-related burns (CSBs) comprise a large proportion of burn injuries globally. A cookstove is any apparatus that provides heat and is used for cooking (e.g., three-stone fire, traditional or improved cookstove). There are limited data on patterns of cooking behaviors and CSBs to inform prevention initiatives and advocacy. We aimed to describe the epidemiology, risk factors and outcomes of cooking-related burns and CSBs, specifically. Methods Patients with cooking and non-cooking related burns from 2018 to 2020 were identified in the World Health Organization (WHO) Global Burn Registry (GBR). Patient demographics, cooking arrangement, injury characteristics [mechanism, total body surface area (TBSA), revised Baux score] and outcomes were described. Differences in proportions and medians were compared. Bivariate regression was performed to identify risk factors associated with occurrence of CSB. Results GBR contained data of 6,965 burn-injured patients from 17 countries; 88% were from middle-income countries. One quarter of burn injuries (1,723 burns) were cooking-related. More than half of cooking-related burns (55%) occurred in females. Median age for cooking-related burns was 11 years (IQR 2–35). Of cooking-related burns, 22% were cookstove-related burns (CSBs; 311 burns). The most common mechanism in CSB was flame (87%), whereas the most common mechanism in other cooking burns was scald (62%). Patients with CSBs were more often female (65% vs 53%; p< 0.001) and much older than patients with other cooking burns (32 years, IQR 22–47 vs 5 years, IQR 2–30). CSBs were significantly larger in TBSA size (30%, IQR 15–45% vs 15%, IQR 10–25%; p< 0.001), had higher revised Baux scores (70, IQR 46–95 vs 28, IQR 10–25; p< 0.001) and more often resulted in death (41 vs 11%; p< 0.001) than other cooking burns (Table1). Patients with CSBs were more likely to be burned by fires (OR 4.74; 95% CI 2.99–7.54) and explosions (OR 2.91, 95% CI 2.03–4.18) than other cooking injuries. Kerosene had the highest odds of CSB than all other cooking fuels (OR 2.37, 95% CI 1.52–3.69). Conclusions Cooking-related burns are common and have different epidemiology than CSBs, specifically (e.g., more often female, older, larger burn size, higher mortality). CSBs were more likely caused by structural factors (e.g., explosion, fire) than behavioral factors (e.g., accidental movements) when compared to other cooking burns.

Biomass cookstove is widely used in the rural areas of Nepal for cooking and space heating. Its thermal and emission performance keeps importance environmentally, economically and socially.  Chimney operated two pot raised mud Improved Cookstove (ICS) is one of Nepal’s most promoted cookstoves. The goal of this study is to evaluate the thermal and emission performance. Thermal and emission performance has been obtained by water boiling test and emission parameters have been measured by using Laboratory Emissions Monitoring System (LEMS). The thermal efficiency of cookstove has been improved from 17.99% to 24.7 % i.e. Tier 1 to 2 with the fabrication of appropriate material and accessories. Similarly total emission performance has been found in Tier 1 and fugitive emission performance has been found in Tier 5. Experimental results of thermal efficiency and fugitive emission complied with the performance target of the cookstove.

Abstract Background Household air pollution from biomass fuels burning in traditional cookstoves currently appeared as one of the most serious threats to public health with a recent burden estimate of 2.6 million premature deaths every year worldwide, ranking highest among environmental risk factors and one of the major risk factors of any type globally. Improved cookstove interventions have been widely practiced as potential solutions. However, studies on the effect of improved cookstove interventions are limited and heterogeneous which suggested the need for further research. Methods A cluster randomized controlled trial study was conducted to assess the effect of biomass-fuelled improved cookstove intervention on the concentration of household air pollution compared with the continuation of an open burning traditional cookstove. A total of 36 clusters were randomly allocated to both arms at a 1:1 ratio, and improved cookstove intervention was delivered to all households allocated into the treatment arm. All households in the included clusters were biomass fuel users and relatively homogenous in terms of basic socio-demographic and cooking-related characteristics. Household air pollution was determined by measuring the concentration of indoor fine particulate, and the effect of the intervention was estimated using the Generalized Estimating Equation. Results A total of 2031 household was enrolled in the study across 36 randomly selected clusters in both arms, among which data were obtained from a total of 1977 households for at least one follow-up visit which establishes the intention-to-treat population dataset for analysis. The improved cookstove intervention significantly reduces the concentration of household air pollution by about 343 μg/m3 (Ḃ = − 343, 95% CI − 350, − 336) compared to the traditional cookstove method. The overall reduction was found to be about 46% from the baseline value of 859 (95% CI 837–881) to 465 (95% CI 458–472) in the intervention arm compared to only about 5% reduction from 850 (95% CI 828–872) to 805 (95% CI 794–817) in the control arm. Conclusions The biomass-fuelled improved cookstove intervention significantly reduces the concentration of household air pollution compared to the traditional method. This suggests that the implementation of these cookstove technologies may be necessary to achieve household air pollution exposure reductions. Trial registration The trial project was retrospectively registered on August 2, 2018, at the clinical registry database ( with the NCT03612362 registration identifier number.
