Fig. 4: Sensitivity of India-wide particulate matter exposure to a reduction of burning in different locations.
From: Air quality impacts of crop residue burning in India and mitigation alternatives

a Percent reduction in contribution to air quality impacts per 1% reduction in agricultural burning emissions in wheat residue burning season (April-May) in different states. b Zoom-in of a, i.e. districts in northwestern India. c, d are same as a and b but for rice residue burning season (October–November), hence the greater color bar limits as shown in d compared to b. India administrative maps are obtained from the Database of Global Administrative Areas, Version 4.150. Coast outlines are plotted based on data in Python Matplotlib Basemap Toolkit, Version 1.2.1.
