Biomass and bio-waste are currently the most efficient and abundant renewable resources, serving as the cornerstone of a bioeconomy. In the coming decades, the bioeconomy will rely on biomass for energy production. Despite being aware of its advantages, farmers nevertheless burn a huge amount of crop residues so that the land is ready for the next cultivation. Crop residue burning on farms is an issue that has worsened by mechanized farming, lack of low-skilled farm labor, and high associated costs. Rice, wheat, cotton, maize, millet, sugarcane, jute, rapeseed-mustard, and groundnut residue burning has increased in irrigated areas where numerous crops are cultivated annually, as well as in areas adjacent to the national capital region and satellite cities. Northern India’s stubble burning is a substantial contributor to atmospheric particulate matter (PM) and trace gases, which have a negative impact on the local and regional climate and pose serious health hazards. There is currently a lack of scientific data on how these burnings affect the air quality over the national capital Delhi. The current analysis evaluates the contribution of CO and PM2.5 from such biomass-burning activities to the pollution load in Delhi based on the satellite-retrieved stubble-burning activities in the year 2021 and the MODIS active fire count data for Punjab and Haryana. Some alternatives of stubble burning are also suggested in this chapter, which includes compositing, mulching, briquette formation, biochar, and bioenergy.
