P3 Ghana Cookstove Study

Background:

Despite their potential health and social benefits, adoption and use of improved cookstoves has been low throughout much of the world. Explanations for low adoption rates of these technologies include prices that are not affordable for the target populations, limited opportunities for households to learn about cookstoves through peers, and perceptions that these technologies are not appropriate for local cooking needs. The P3 project employs a novel experimental design to explore each of these factors and their interactive effects on cookstove demand, adoption, use and exposure outcomes.

Methods:

The P3 study is being conducted in the Kassena-Nankana Districts of Northern Ghana. Leveraging an earlier improved cookstove study that was conducted in this area, the central design of the P3 biomass stove experiment involves offering stoves at randomly varying prices to peers and non-peers of households that had previously received stoves for free. Using household surveys, electronic stove use monitors, and low-cost, portable monitoring equipment, we measure how prices and peers' experience affect perceptions of stove quality, the decision to purchase a stove, use of improved and traditional stoves over time, and personal exposure to air pollutants from the stoves.

Discussion:

The challenges that public health and development communities have faced in spreading adoption of potentially welfare-enhancing technologies, like improved cookstoves, have highlighted the need for interdisciplinary, multisectoral approaches. The design of the P3 project draws on economic theory, public health practice, engineering, and environmental sciences, to more fully grasp the drivers and barriers to expanding access to and uptake of cleaner stoves. Our partnership between academic institutions, in the US and Ghana, and a local environmental non-governmental organization creates unique opportunities to disseminate and scale up lessons learned.

Exclusion criteria

  • Clusters that are close to the S1 clusters, creating a set of clusters far enough from the original R group that will create the S2 cluster.

Treatment and study plan

P3 Bio Intervention

Behavioral

Two types of improved biomass burning cookstoves (ACE1 and Greenway Jumbo) are offered to participants in both arms at varying prices.

Primary outcomes

  1. Stove Purchases | Number of households that order stoves and complete payments

    Time frame: up to 13 months

    Number of households in each arm that place orders for and subsequently complete all payments on the two types of stoves.

Secondary outcomes

  1. Cooking Behaviors | Household use of both traditional and improved cookstoves over time

    Time frame: up to 13 months

    Use of traditional and improved stoves over time across intervention arms.

  2. Perceptions of Stove Quality | Smoke production, efficiency, ease of use, quality of food, etc.

    Time frame: up to 13 months

    Likert-scale and subjective expectation questions measuring perceptions of stove quality / performance for both stove types along multiple dimensions. Example scale question: "How much smoke do you think the ACE1 stove would produce?" Response options: 1 = A lot less smoke than a 3 stone fire, 2 = A little less smoke than a 3 stone fire; 3 = About the same amount of smoke as a 3 stone fire; 4 = A little more smoke than a 3 stone fire; 5 = A lot more smoke than a 3 stone fire; 99 = Don't know / not sure.

  3. Exposure to CO and PM 2.5

    Time frame: up to 13 months

    Kitchen concentrations of and personal exposure to carbon monoxide (CO) and particular matter (PM2.5) among study participants
