The Use of Behaviour Change Techniques in Clean Cooking Interventions to Achieve Health, Economic and Environmental Impact: A review of the evidence and scorecard of effectiveness, 2014. (Executive summary)

Authors: Nicholas J. Goodwin, Sarah Ellen O’Farrell, Kirstie Jagoe, et al.

The aim of this study was to review the use of behaviour change approaches in clean cooking interventions in resource-poor settings. Using publicly available data, the report synthesises the evidence of the use of behaviour change techniques (BCTs) for human and environmental outcomes and impact. The report includes a set of case studies on selected interventions that use BCTs and applies a scorecard to assess the effectiveness of each intervention’s approach to behaviour change. The report then discusses the findings from the review and case studies and includes a set of recommendations for the clean cooking sector to consider. A planned task was to compare interventions through an economic return on investment (cost-benefit) lens, however the availability and consistency of data did not make this possible.



Behavioral Attitudes and Preferences in Cooking Practices with Traditional Open-Fire Stoves in Peru, Nepal, and Kenya: Implications for Improved Cookstove Interventions. Int. J. Environ. Res. Public Health 2014, 11(10).

Global efforts are underway to develop and promote improved cookstoves which may reduce the negative health and environmental effects of burning solid fuels on health and the environment. Behavioral studies have considered cookstove user practices, needs and preferences in the design and implementation of cookstove projects; however, these studies have not examined the implications of the traditional stove use and design across multiple resource-poor settings in the implementation and promotion of improved cookstove projects that utilize a single, standardized stove design.

We conducted in-depth interviews and direct observations of meal preparation and traditional, open-fire stove use of 137 women aged 20–49 years in Kenya, Peru and Nepal prior in the four-month period preceding installation of an improved cookstove as part of a field intervention trial. Despite general similarities in cooking practices across sites, we identified locally distinct practices and norms regarding traditional stove use and desired stove improvements. Traditional stoves are designed to accommodate specific cooking styles, types of fuel, and available resources for maintenance and renovation. The tailored stoves allow users to cook and repair their stoves easily. Women in each setting expressed their desire for a new stove, but they articulated distinct specific alterations that would meet their needs and preferences.

Improved cookstove designs need to consider the diversity of values and needs held by potential users, presenting a significant challenge in identifying a “one size fits all” improved cookstove design. Our data show that a single stove design for use with locally available biomass fuels will not meet the cooking demands and resources available across the three sites. Moreover, locally produced or adapted improved cookstoves may be needed to meet the cooking needs of diverse populations while addressing health and environmental concerns of traditional stoves.

Background – Three billion people are exposed to household air pollution from biomass fuel use. Exposure is associated with higher incidence of pneumonia, and possibly tuberculosis. Understanding mechanisms underlying these defects would improve preventive strategies.

Methods – We used human alveolar macrophages obtained from healthy Malawian adults exposed naturally to household air pollution, and compared with human monocyte-derived macrophages exposed in vitro to respirable-sized particulates. Cellular inflammatory response was assessed by: IL-6 and IL-8 production in response to particulate challenge; phagocytosis of fluorescent-labelled beads and intraphagosomal oxidative burst capacity; ingestion and killing of Streptococcus pneumoniae and Mycobacterium tuberculosis measured by microscopy and quantitative culture. Particulate ingestion was quantified by digital image analysis.

Results – We were able to reproduce the carbon loading of naturally exposed alveolar macrophages by in vitro exposure of monocyte derived macrophages. Fine carbon black induced IL-8 release from monocyte derived and alveolar macrophages (p<0.05), with similar magnitude responses (log10 increases of 0.93 [SEM 0.2] vs 0.74 [SEM 0.19] respectively). Phagocytosis of pneumococci and mycobacteria was impaired with higher particulate loading. High particulate loading corresponded with a lower oxidative burst capacity (p=0.0015). There was no overall effect on killing of M. tuberculosis.

Conclusion Alveolar macrophage function is altered by particulate loading. Our macrophage model is comparable morphologically to the in vivo uptake of particulates. Wood smoke exposed cells demonstrate reduced phagocytosis but unaffected mycobacterial killing, suggesting defects related to chronic wood smoke inhalation limited to specific innate immune functions.

This paper presents results of three United States Environmental Protection Agency (U.S. EPA) sponsored field studies which assessed the fuel consumption impacts of household energy programs in Benin, Uganda, and Gujarat, India. These studies expand on a previous round of U.S. EPA supported efforts to build field testing capacity and collect stove performance data in Peru, Nepal, and Maharashtra, India. Daily fuel consumption estimates of traditional and intervention technologies were made using the Kitchen Performance Test (KPT) protocol to determine the potential fuel savings associated with the respective programs.

The programs in Benin and Gujarat, India resulted in significant fuel savings of approximately 29% and 61%, respectively. In Uganda, the homes using liquefied petroleum gas (LPG) consumed approximately 31% less charcoal than those not using LPG, although the total energy consumption per household was similar between the baseline and LPG user groups.

Published on Sep 16, 2014 – Watch to see how a simple solution can improve life for the nearly 3 billion people who rely on wood- or coal-powered open cookstoves, and reduce carbon pollution along the way.

Over three billion people worldwide cook with traditional stoves, which typically consist of three stones and an open fire. The harmful emissions produced from these types of stoves are known to cause fatal illnesses. Traditional stoves claim the lives of up to 4 million people every year and cause the death of more children under the age of five than any other single cause. In addition, widespread land degradation and deforestation have resulted from inefficient fuel consumption of traditional stoves. In order to address these issues, investigations into the use of dung-burning top-lit up-draft (TLUD) microgasifier cookstoves, that produces biochar as a byproduct, have been conducted at the University of Adelaide. Results indicate that dung from various grazing
animals burnt in the TLUD stove have similar heating properties, implying that the stove is applicable to a wide client-base. Additionally, biochar from cow-dung combustion is as good, if not better than some commercially available biochar.

Household air pollution and lung cancer in China: a review of studies in Xuanwei. Chinese Journal of Cancer, Ahead of Print, Sept 2014. DOI: 10.5732/cjc.014.10132

Over half of the world’s population is exposed to household air pollution from the burning of solid fuels at home. Household air pollution from solid fuel use is a leading risk factor for global disease and remains a major public health problem, especially in low- and mid-income countries. This is a particularly serious problem in China, where many people in rural areas still use coal for household heating and cooking.

This review focuses on several decades of research carried out in Xuanwei County, Yunnan Province, where household coal use is a major source of household air pollution and where studies have linked household air pollution exposure to high rates of lung cancer. We conducted a series of case-control and cohort studies in Xuanwei to characterize the lung cancer risk in this population and the factors associated with it. We found lung cancer risk to vary substantially between different coal types, with a higher risk associated with smoky (i.e., bituminous) coal use compared to smokeless (i.e., anthracite) coal use.

The installation of a chimney in homes resulted in a substantial reduction in lung cancer incidence and mortality. Overall, our research underscores the need among existing coal users to improve ventilation, use the least toxic fuel possible, and eventually move toward the use of cleaner fuels, such as gas and electricity.
