About the Conference

Atmospheric aerosols, comprising solid and liquid particles suspended in the air, originate from natural sources such as wind-borne dust, sea spray, volcanic debris, and biogenic emissions, as well as anthropogenic activities including industrial emissions, agricultural practices, fossil fuel combustion, waste burning, and biomass burning. These aerosols significantly impact regional and global climate by influencing air quality, cloud formation, atmospheric chemistry, the greenhouse effect, and Earth's radiation balance.

Moreover, aerosols pose serious health risks, contributing to chronic respiratory diseases and asthma. In recent decades, anthropogenic aerosol emissions have surged due to increasing vehicular emissions, urbanization, and industrial growth. Studies, both national and international, have reported elevated air pollution levels across the Indo-Gangetic Plain (IGP) and Brahmaputra Valley regions of India. Northern India experiences severe winter smog episodes driven by stubble burning, industrial emissions, and vehicular pollution. According to a World Health Organization survey, Delhi has the poorest air quality among major global cities.

Pollutants from these regions are transported by air masses from the southwest during pre-monsoon and winter seasons, reaching high-altitude Himalayan areas, including Nepal and Tibet, via valley corridors. This transboundary pollution affects weather patterns and climate in the ecologically sensitive Himalayan region. Locally, in Uttarakhand, rising tourism, urbanization, and forest fires further exacerbate aerosol emissions.

To address these challenges, Hemvati Nandan Bahuguna Garhwal University (HNBGU), Srinagar-Pauri Garhwal, Uttarakhand, is organizing the “Third International Multidisciplinary Conference on Aerosols, Air Quality and Climate Change (IMCAAC-2025) over the Himalayan Region (Aligned with the Objectives and Themes of Bharat's National Education Policy 2020)” — "हिमालयी क्षेत्र में एरोसोल, वायु गुणवत्ता और जलवायु परिवर्तन पर तृतीय वार्षिक अंतरराष्ट्रीय संगोष्ठी — (भारत की राष्ट्रीय शिक्षा नीति 2020 के उद्देश्यों और विषयवस्तु के अनुरूप)". The event, hosted by the Department of Physics, School of Science, HNBGU, Srinagar (Garhwal), India, will take place from 13–15 October 2025.

The conference aims to foster interaction and promote the adoption of innovative techniques to mitigate air pollution and its impacts on the Himalayan region.
