Field Crop Residue burning Induced Particulate Pollution in NW India - Policy Challenges & Way Forward

Abstract

The study aims to provide insights into the effectiveness of numerous policy interventions to curb FCRB-induced air pollution in NW India. The problem is addressed by examining the trend and co-existence of VIIRS retrieved thermal anomalies in NW states and PM2.5 concentrations in New Delhi during the two harvesting seasons (April-May &Oct-Nov) over the period 2014-2020. The findings reveal that various governmental measures that primarily revolve around sustainable residue management practices cannot holistically curb the stubble burning practice in NW India and the related air pollution in neighboring states. The study suggests that besides the short-term residue management measures, crop diversification or discontinuing dual rice-wheat cultivation is the only long term measure to regulate widespread stubble burning and the deteriorating air quality.
