Understanding Bahraich Air Quality

Bahraich, in Bahraich district, is embedded in Uttar Pradesh's sugarcane belt - one of the most agriculturally intensive regions in India and a major driver of seasonal air quality cycles.

The air quality calendar in Bahraich follows the sugarcane agricultural cycle precisely. The crushing season (October–April) brings sustained emissions from sugar mill stacks, while bagasse burning provides thermal energy but adds to ambient PM. Simultaneously, paddy field burning from the kharif harvest (October–November) and wheat stubble burning after the rabi crop (April–May) create two agricultural burning peaks annually. The Saryu River (Ghaghra); Sarda River basin's flat terrain ensures minimal natural dispersion.

Winter months (November–February) combine all sources simultaneously: sugar mill operations, agricultural burning, widespread biomass cooking fuel, and brick kiln activity under temperature inversions that are among the most severe in the Indo-Gangetic Plain. PM2.5 readings of 150–250 µg/m³ are not uncommon during peak episodes. The monsoon (July–September) provides the year's cleanest air as rainfall suppresses all dust and temporarily interrupts agricultural burning cycles.

  • Biomass burning
  • Brick kilns
  • Sugarcane mill emissions
  • Vehicle exhaust
  • Road dust

Geography: Nepal border district; Sarda River terai zone; Dudhwa Tiger Reserve proximity; sugar belt

Frequently Asked Questions — Bahraich

When is air quality worst in Bahraich?

Air quality in Bahraich is at its worst during November through February, when winter temperature inversions over the Gangetic Plain trap emissions from agricultural burning, biomass burning, and biomass burning near the surface. The combination of post-kharif agricultural burning (October–November), brick kiln activation, and cold inversion episodes creates PM2.5 readings that frequently exceed 150 µg/m³ and sometimes approach 300 µg/m³ during the most severe episodes.

What are the main air pollution sources in Bahraich?

Bahraich's main pollution sources are: agricultural burning, biomass burning, brick kilns, sugarcane mill emissions. Like most Uttar Pradesh cities, the seasonal pattern is defined by agricultural burning cycles (kharif in October–November, rabi in April–May), year-round brick kiln operations during the dry season (October–April), and persistent biomass burning for domestic energy. The agriculture activities add a distinctive industrial or agricultural dimension specific to Bahraich.
