ABSTRACT

The study examine the efficacy of government policy interventions initiated since 2014 to curb FCRB in NW Indian states and the related air pollution in Delhi-NCR during 2014-2019. The regression analysis suggests an increase in PM2.5 of ~69 µg/m3/1000 surge in fires. VIIRS retrieved data suggest an overall declining trend of ~1606 and ~4308 fire counts per year across NW states during October-November respectively. The monthly PM2.5 concentrations in New Delhi exhibits a decline of ~2.18 µg/m3 and ~5.17 µg/m3 per year over the same period. Despite an overall increase of ~17.6 % rice productivity, a noted decrease in fire activity over the period is an encouraging move, likely a result of some control imposed by authorities on FCRB. Owing to a significant ~35.5% rise in wheat productivity, data records rising trend in wheat residue burning activities in April (~1298/year) and May (~2402/year) but do not trigger extreme pollution due to difference in intensity of fires across harvesting seasons and relatively weak northwesterly wind direction. Nevertheless, the overall high PM2.5 levels in October-November and April-May compared to NAAQS 24-hour average of 60µg/m3, disproves the overall efficacy of government policies to curb FCRB and related air pollution in IGP region.

检查政策与实践之间的差距-印度西北部的农作物燃烧引起的颗粒物污染问题

摘要

该研究调查了自2014年以来启动的政府政策干预措施的有效性,该措施旨在遏制印度西北部各州的FCRB以及2014-2019年德里-NCR的相关空气污染。回归分析表明,火灾中PM2.5的增加量为〜69 µg / m3 / 1000。VIIRS检索到的数据表明,在10月至11月期间,西北各州每年的火警总数总体呈下降趋势,分别为〜1606和〜4308。在同一时期,新德里的每月PM2.5浓度每年分别下降〜2.18 µg / m3和〜5.17 µg / m3。尽管稻米生产率总体提高了约17.6%,但在此期间,火灾活动的明显减少是令人鼓舞的,这可能是当局对FCRB施加了一些控制的结果。由于小麦生产力显着提高〜35.5%,数据记录了4月(〜1298 /年)和5月(〜2402 /年)的小麦残渣燃烧活动呈上升趋势,但由于收获季节之间火势的差异以及西北风向相对较弱,因此并未引发极端污染。尽管如此,与NAAQS 24小时平均水平60µg / m3相比,10月至11月和4月至5月的PM2.5总体较高水平,证明了政府遏制IGP地区FCRB和相关空气污染的政策的整体效力。
