The Shamba Chef Educational Entertainment Program to Promote Modern Cookstoves in Kenya: Outcomes and Dose-Response Analysis.

BACKGROUND: Globally, an estimated 3.6 billion people rely on solid fuels for cooking over open fires or in simple cookstoves. Universal access to clean cooking fuels and technology by 2030 is a United Nations' Sustainable Development Goal. METHODS: The Mediae Company created a home makeover television and radio show, Shamba Chef, designed to promote modern, cleaner, safer cooking methods and improved nutrition in Kenya, which reached 5 million homes in late 2017. This was accompanied by a mobile phone platform called iChef. Researchers evaluated the effects of Shamba Chef on cookstove purchase, use, and attitudes, beliefs, and intentions. RESULTS: The study revealed dose-response effects of Shamba Chef exposure on several key outcomes. Exposure to the program was associated with an awareness of improved biomass stoves (OR 4.4; 95% CI 2.8 to 6.9), and aspirations to own an improved biomass stove (OR 2.0; 95% CI 1.4 to 2.9). Receiving information about modern stoves from two or more sources generated greater awareness of liquefied petroleum gas (LPG) stoves (OR 2.0; 95% CI 1.3 to 3.1). The qualitative study revealed that Shamba Chef explained how the stoves worked, communicated their benefits, and encouraged participants to trust and purchase those cookstoves. CONCLUSION: Shamba Chef was successful in influencing determinants of cookstove purchase and use, and there is evidence from the qualitative study that it influenced the purchase and use of improved biomass stoves.

Evaluation of Behavior Change Communication Campaigns to Promote Modern Cookstove Purchase and Use in Lower Middle Income Countries.

Nearly three billion people worldwide burn solid fuels and kerosene in open fires and inefficient stoves to cook, light, and heat their homes. Cleaner-burning stoves reduce emissions and can have positive health, climate, and women's empowerment benefits. This article reports on the protocol and baseline data from the evaluation of four behavior change communication (BCC) campaigns carried out in lower to middle income countries aimed at promoting the sale and use of cleaner-burning stoves. Interventions implemented in Bangladesh, Kenya, and Nigeria are using a range of BCC methods including mass media, digital media, outdoor advertising, and inter-personal communication. The mixed methods evaluation comprises three large-scale surveys: one pre-BCC and two follow-ups, along with smaller scale assessments of stove uptake and patterns of use. Baseline results revealed varying levels of awareness of previous promotions and positive attitudes and beliefs about modern (i.e., relatively clean-burning) cookstoves. Differences in cookstove preferences and behaviors by gender, socio-demographics, media use, and country/region were observed that may affect outcomes. Across all three countries, cost (lack of funds) a key perceived barrier to buying a cleaner-burning stove. Future multivariate analyses will examine potential dose-response effects of BCC on cookstove uptake and patterns of use. BCC campaigns have the potential to promote modern cookstoves at scale. More research on campaign effectiveness is needed, and on how to optimize messages and channels. This evaluation builds on a limited evidence base in the field.
