Significance Poor air quality is the largest environmental health risk in United States and worldwide, agriculture a major source of pollution. Nevertheless, has been largely absent from discussions about impacts food. We estimate quality–related States, finding that 80% 15,900 annual deaths result food-related fine particulate matter (PM 2.5 ) pollution are attributable to animal-based foods. By estimating these exploring how reduce them, this work fills critical knowledge gap. Our results...
Air quality in the United States has dramatically improved, yet exposure to air pollution is still associated with 100000–200000 deaths annually. Reducing number of effectively, efficiently, and equitably relies on attributing them specific emission sources, but so far, this been done for only highly aggregated groups or a select few sources interest. Here, we estimate mortality attributable all domestic, human-caused emissions primary PM2.5 secondary precursors. We present detailed...
 Providing sufficient and nutritious food while reducing climate emissions footprints from systems is a Grand Engineering Challenge for India. The increasing dietary pose serious threat to achieving the national net-zero goal by 2070, yet such are not accounted in India’s Climate Action Plans. Since 1990s, transitions have been largely propelled economic development intensive urbanization, occurred unequally between urban rural regions across India.The regional temporal...
Each year, millions of premature deaths worldwide are caused by exposure to outdoor air pollution, especially fine particulate matter (PM 2.5 ). Designing policies reduce these relies on quality modeling for estimating changes in PM concentrations from many scenarios at high spatial resolution. However, typically has substantial requirements computation and expertise, which limits policy design, countries where most -related occur. Lower requirement reduced-complexity models exist but...
Abstract We present alternative methods for estimating spatial surrogates and temporal factors ammonia (NH 3 ) emissions from chemical fertilizer usage (CFU), in the USA, at scales used to simulate regional air quality deposition of reactive nitrogen ecosystems. The newly developed Improved Spatial Surrogate (ISS) method incorporates year‐specific sales data, high resolution crop maps, local demands allocate NH 4 km × grid cells. Results are compared with commonly gridded emission estimates...
Abstract Ammonia (NH 3 ) emissions from fertilizer application is a highly uncertain input to chemical transport models (CTMs). Reducing such uncertainty important for improving predictions of ambient NH and PM 2.5 concentrations, regulatory policy purposes exploring linkages air pollution human health ecosystem services. Here, we implement spatially temporally resolved inventory fertilizers, based on high-resolution crop maps, nitrogen demand process model, as the Comprehensive Air Quality...
Food, feed, and fuel production are vital for human well-being. Yet current agricultural practices have resulted in extensive multi-media damages, primarily due to reactive nitrogen (Nr) emissions (NH3, N2O, NOx). Managing Nr sustainably alleviate food feed insecurity has been identified as a Grand Engineering Challenge. Systematically analysing source contributions, flows, impacts of is crucial an agro-dominant country like India that faces the dual challenge environmental security 1.6...
India's public health is seriously endangered by air pollution and linked to ∼0.8–0.98 million 0.17 premature deaths annually from chronic exposure particulate matter (PM2.5) ozone, respectively. Air quality forecasting tools are needed assess the spatiotemporal variability of pollutants evaluate impact potential mitigation measures. Gridded concentrations PM2.5 ozone typically derived first principle models called Chemical Transport Models (CTMs). Widespread application CTMs, particularly...
