Clean cookstoves don’t just save lives; they add healthy years to someone’s life.
In November of last year, Trees, Water & People and our Nicaraguan partners, Proleña, partnered with Aprovecho Research Center to compare the emissions from open-fire stoves to those from Proleña’s improved stoves, manufactured in Managua. The results were alarming, which is why we are raising $8,000 to provide 60 clean cookstoves to those 60 study participants still cooking over open fires.
This study took place near Jinotega, Nicaragua with half of the families using traditional open fire stoves, and the other half using Proleña’s clean cookstoves. Each stove user volunteered to wear a small monitoring device that attaches to the shirt near the woman’s face to approximate her exposure to smoke for a 24-hour period. These monitors collect small airborne particles, referred to as PM2.5 in the air quality monitoring field, that are the most commonly measured pollutant coming from wood smoke. PM2.5 particles are widely accepted as a principle source of illnesses like chronic obstructive pulmonary disease, lower respiratory infections, lung cancer, and cardiovascular disease.
The average traditional stove user in this study was consistently exposed to 245 µg/m3 of particulates, qualifying their kitchens as a “HEAVY POLLUTED” environment, according to the EPA’s Air Quality Index. In homes where an improved stove had been introduced and adopted, exposure to indoor air pollution was reduced by an average of 63%.
Averted Disability Adjusted Life Years (ADALY) is a commonly used metric for public health studies that represent the number of years of healthy life made possible by reducing exposure to particulate matter in smoke. Using the ADALY methodology, we determined that if clean cookstoves were installed in 500 homes (helping 2,500 people), we could extend life in that population by 286 years. This is why we’ve launched the “Clean Cookstoves and Healthy Families in Nicaragua” campaign because, quite frankly, cooking shouldn’t kill!
Overall, this study was an excellent reminder that clean cookstoves are indeed critical, tangible tools that can help improve a person’s quality of life measurably. It is difficult to put a price on extra years of health, but with $8,000 we’ll be able to complete funding for 60 stoves needed in Jinotega.
Help thank the women in this study who opened their kitchens to us, and who are still breathing smoke as you read this. Give Health. Give Hope. Give Today!
