This is also the time of year when farmers burn crop residue and brush to make fields ready to sow maize. <figure><img width="1500" height="692" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/2022111012110/636cd9bf9c7e80680e092ebbjpeg.jpg" alt=""><figcaption>Fire races through the undergrowth in a hardwood forest in Rautahat district on Friday afternoon, one of many big flare-ups that smothered Central Nepal in smoke on Friday.

One fire in the forests of lower Manang burnt continuously from November to January.
