Mega-dairies are among the largest ammonia emitters, contributing to fine particulate matter pollution that causes respiratory illnesses and premature death.

They found that the new footpaths encouraged 9% to 27% of the surveyed respondents to walk instead of using motorized transport, which led to a reduction in greenhouse gases and particulate matter.

In this, the researchers show that measures to combat slash-and-burn techniques significantly reduce the concentration of particulate matter in the air.

Levels of larger particulate matter - PM 10 - reached an average of 495, more than 10 times the daily amount considered safe by the WHO.

The level of fine particulate matter in the air, the most damaging to health, also soared well into hazardous levels.
