Biomass burning refers to the process of burning organic materials such as crop residues, forest debris, and grasslands for various purposes, including land clearing, agriculture, and energy production. This process releases large amounts of carbon dioxide, methane, and other greenhouse gases into the atmosphere, contributing to climate change and air pollution. Researchers in this area study the environmental impacts of biomass burning, including its effects on air quality, ecosystems, and human health, as well as potential solutions to mitigate its negative effects. They may also investigate the role of biomass burning in carbon cycling and global climate change.
