Partial Crop Residue Burning Challenge in Air Pollution Mitigation

આ શા માટે મહત્વનું છે

It directly connects to GS3 syllabus topics on environmental pollution, monitoring challenges, and sustainable agricultural practices in the Indo-Gangetic plains.

સારાંશ

A recent study points out that 'partial burning' of crop residue—where fields are only partially torched—remains a persistent challenge in mitigating farm fire pollution affecting Delhi-NCR. This practice undermines accurate satellite monitoring and points to gaps in current residue management strategies.

મુખ્ય મુદ્દા

A study highlights that 'partial burning' of crop residue continues to be a major hurdle in tackling farm fire pollution in northern India.
Partial burning occurs when only a portion of the residue is burned or ignition is incomplete, making satellite detection difficult and distorting official estimation of farm fires.
Stubble burning remains a primary seasonal contributor to severe air pollution episodes in Delhi-NCR during the winter months.
Effective management requires moving beyond mere punitive measures to address the socio-economic and operational constraints faced by farmers regarding crop residue management machinery.

Satellite monitoring provides an accurate, complete, and real-time census of all farm fire incidents across northern India.

Aspirants often assume polar-orbiting satellites capture all farm fires accurately in real-time, missing the temporal window limitation.

Environment Agriculture Management

What are the primary in-situ and ex-situ crop residue management technologies promoted in India?

In-situ Machinery: In-situ management incorporates residue into soil using machinery like Happy Seeder, Super Seeder, Smart Seeder, and Mulcher without burning.
Ex-situ Uses: Ex-situ management involves removing residue from the field for industrial use, such as biomass power plants, bio-ethanol production, and packaging material.
Pusa Decomposer: Decomposer application involves spraying microbial bio-enzymes to rapidly accelerate the decomposition of stubble directly in the fields.
