With colleagues at Berkeley Air Monitoring Group, the World Bank, and LIRE (Vientiane), we are developing standard methods for estimating the health benefits (in the form of ADALYs – avoided disability-adjusted life years) that can be attributed to a stove project to introduce advanced combustion stoves in villages within the Savannakhet region of Laos. This project, led by L. Drew Hill, PhD, involved air pollution field work before and after the introduction of the stoves, modeling changes in personal exposure to PM2.5, and using the Household Air Pollution Intervention Tool (HAPIT) to calculate the estimated change in adult and child disease rates that would result.
