An accurate characterization of the seasonal and inter-annual variability of agricultural residue burning in tropics is needed to devise strategies to control or minimize substantial amounts of particulate matter and pollutants released to the atmosphere through the burning of agricultural residues. The present study quantifies the spatiotemporal changes in agricultural residue burning in Madhya Pradesh, India. In this study, the Moderate Resolution Imaging Spectroradiometer (MODIS) data on the occurrence of fire over a period of 15 years (2002–2016) was used to characterize the spatial and temporal patterns of agricultural residue burning in Central India. Overall, there was an increasing trend of fire occurrence, which increased from 1268 in 2002 to 7915 in 2016. Most of these fires were in croplands (48.1%) followed by deciduous broadleaf forests (36%). Cropland fires were increased almost 10-fold from 454 in 2002 to 4359 in 2016 at an average annual rate of 64%. The agricultural residue fires were high in Rabi harvesting period (March to May), as compared to that in Kharif harvesting period (October to December). The present study indicates an increased agricultural residue burning activity in the Madhya Pradesh and needs an immediate attention and develop sustainable alternative methods for crop residue management. The present study also suggests that Modis can be used for long-term assessment of small fires. We recommend ploughing of agricultural residues into the soil as a sustainable and eco-friendly alternative to the burning of crop residues.
