Air pollution has become a matter of great concern, particularly in megacities and urban areas, and rapid industrial development coupled with emission from the transport sector, which are recognized as the prime sources. Natural sources, such as sand and dust storms also add to the air pollution burden. The situation is alarming and gradually becoming more severe, and it is expected to increase with the population expansion. Either natural or anthropogenic sources may cause air pollution, and the latter is broadly categorized through industrial, commercial, and vehicular activities. The 1st International Conference on Applications of Air Quality in Science and Engineering (ICAAQSE), 10–12 February 2020 is an international dissemination hub of air quality studies, research, and their applications in science and engineering. The conference is to be held in the State of Kuwait. The ICAAQSE 2020 aims to bring together leading academic scientists, researchers, and scholars to exchange and share their experiences, practices, and results about all aspects of air quality and its applications in science and engineering. It also provides the premier interdisciplinary forum for scientists, researchers, practitioners, government officials, and educators to present and discuss the most recent innovations, trends, concerns, and practical challenges encountered and the solutions adopted in the field of air quality and its applications in science and engineering. Over the years, the topic of air quality has increased its prominence as a critical issue for achieving sustainable development and to reduce health impacts in all regions of the world. Scientific research has revealed the complex nature of the impact of air pollution, which spans multiple scales and involves numerous physical and chemical interactions including climate change. As always, the conference brings together participants from the air quality, climate, health research, and user communities to discuss the latest research advances, studies, practices, and new applications to highlight the significant implications for the policies and the users. The outcome of such research needs to be contextualized within wellformulated communication strategies that help the policy makers and the citizens to understand and appreciate the risks and rewards arising from air quality management.
