As a crispness starts to sharpen the August nights in Fort Collins, it can only mean two things: 1) fall is nipping at the heels of summer, and 2) it’s time to head back to Honduras. Admittedly, the summer in Colorado has been luxurious with yoga classes, buttercream cupcakes, and Internet access everywhere- all things decidedly unavailable in the small town of La Esperanza, Honduras where we do our cookstove fieldwork.
The past three months in Colorado has also given my colleagues and me an opportunity to dig into the rich data we collected from 525 women across 14 farming villages from September 2014 through May 2015. Of this sample, we had 85 women who owned a Justa cookstove and answered questions about stove preferences and behaviors.
Initial Findings from Justa Cookstove Users
The Justa (pronounced ‘who-sta’) clean cookstove, originally designed by Trees, Water & People and engineers from the Aprovecho Research Center, is a cleaner-burning cookstove with an insulated combustion chamber in a “rocket elbow” shape with a built-in chimney to ventilate toxic smoke from the home. The majority of Justa stoves in this region of Honduras are provided by non-governmental organizations, and most women (92%) in our sample supplied materials or paid some money to help with construction costs of their stove. Over 95% of Justa stove owners in our sample reported their Justa stove was better than their traditional stove to cook tortillas, keep smoke out of the house, and maintain cleanliness. Every single woman with a Justa in our sample said that it used less wood than their traditional stove. These findings are especially important considering that on average, our sample of Justa owners use their stoves for 10 hours a day!
There are other models of improved stoves in this region, too. Our preliminary data suggest some differences between these models regarding their efficiency and condition. For example, 74% of Justa stoves were still in good condition based on researcher observation, while only 42% of the other improved stoves were in good condition. There are many possible reasons for these differences. One reason might be that the technicians that build the Justa stoves spend time teaching the owner how to clean and maintain their stove. This education is crucial to help owners understand how to properly use their new stove and keep it working well for the long-term.
We are learning that there is so much more to explore about stove use in this area. Our next round of the study aims to build Justa stoves for 300 women between the ages of 25-55 years. We plan to carefully measure their health and household air pollution over time to see if there are improvements as they transition away from their traditional stove.
As we pack our bags to head back to Honduras for four months of fieldwork during the rainy season (or should I call it the downpour season?), I find myself weighing the pros and cons of doing meaningful work in a developing country, versus the sinful delight of my favorite vanilla cupcake at Buttercream. Sigh. Cookstoves win, again.
