University of Idaho researcher Alex Maas is leading a multi-institutional study to assess how sustainable farming practices impact air quality in the western U.S. Motivated by dusty air in Moscow, Idaho, Maas will analyze air-quality sensor data spanning two decades, focusing on how weather, harvest timing, farming practices, and non-agricultural land-use factors contribute to air quality and health outcomes. Maas hopes the findings will help policymakers understand the broader environmental impact of agricultural practices and encourage new technologies that enhance sustainability while managing unintended effects on air quality.
