Abstract

Fast-developing countries, particularly in Southeast Asia, are critically susceptible to high concentrations of inhalable fine particulate pollution (PM2.5), which threatens public health and economic development. This study evaluates the incremental reduction in PM2.5 concentrations and its potential health and economic benefits, focusing on sustainable air quality management in vulnerable communities, particularly in the fisheries sector in the Philippines. Using satellite-derived PM2.5 data and the Environmental Benefits Mapping and Analysis Program–Community Edition (BenMAP-CE) model, the estimated premature mortality rates and the associated costs under various concentration reduction scenarios (25%, 50%, 75%, and 100%) for the regions of Navotas, Bohol, and Davao Del Sur revealed substantial health and economic benefits. Under 25–50% reduction scenarios, it could prevent annual premature mortalities of 55–104 in the three regions, generating approximately USD 1.15 million in monetary benefits. A more considerable 75–100% reduction scenario could prevent up to 206 mortalities annually, yielding USD 2.07 million in monetary benefits. These benefits were notable in areas with higher baseline PM2.5 concentrations, such as Navotas and Davao Del Sur, which experienced significant reductions in premature mortality within the range of 1–3% of the fisherfolk population. These findings highlight the incremental reduction strategies in a sector-specific approach to protect vulnerable communities crucial for economic development. The developed approach aims to improve the air quality in fishing-dependent regions to ensure sustainable livelihoods across the Philippines while meeting national and global health targets.
