Abstract:
... On-site open burning is a common practice for handling rice straw, but its negative impacts, e.g., biomass loss and air pollution, are largely debated worldwide. To address the negative effects of open burning, many efforts have been made to ‘ignite’ worldwide bans. However, these bans are likely based on a singular view in which some positive aspects of open burning are overlooked. In this study, ...
