Sapling: working in one or two places

Alternatives to crop residue burning

Give farmers affordable ways to sow through, mulch or sell crop straw so they no longer need to burn it.

Start small

Run a demonstration on 5 to 10 farms in one village using one rented Happy Seeder or Super Seeder through a custom hiring centre, side by side with a burned plot. Time: one harvest season (about 4 to 6 weeks of sowing, yields at the next harvest). Cost: hire fees of roughly a few thousand rupees per hectare, or a shared machine at a few lakh rupees with subsidy. People: one lead farmer, one tractor operator, one extension officer from a Krishi Vigyan Kendra, and a local cooperative or farmer producer organisation to run bookings.

The problem

Seasonal burning of rice straw and maize stalks releases greenhouse gases and black carbon, and creates smoke that chokes cities like Delhi and Chiang Mai every year.

Where it fits

Arises in intensive double-cropping systems with a short window between harvest and next sowing (rice to wheat in Punjab and Haryana, maize in northern Thailand, grain belts in China). Needs machines that can sow into standing residue (Happy Seeder, Super Seeder) or collect it (balers), shared access through custom hiring centres or cooperatives, buyers for straw (biomass power, fodder, industry), and a few trusted farmers to show it works.

The principle underneath

Burning persists because it is the cheapest, fastest option in a tight window. Bans alone push it out of sight; what works is making the alternative cheaper or more profitable than the match, through shared machines, a market for straw, or proof of better yields.

A pattern in nature

A forest floor: fallen leaves are left to rot in place as mulch, feeding the soil instead of being cleared.

Who to call

CIMMYT and Borlaug Institute for South Asia (BISA); Punjab Agricultural University (Happy Seeder developers); ICAR and Krishi Vigyan Kendras; The Nature Conservancy India; iFOREST (independent fire monitoring); Chiang Mai University fire tracking researchers; farmer producer organisations and custom hiring centres in Punjab and Haryana.

Watch out for

Measuring success by machines distributed rather than hectares not burned. Subsidies captured by larger farmers or the same farmers twice. Machines idle because the sowing window clashes and there are too few to rent. Relying on satellite fire counts that farmers can dodge. Overselling bio-decomposer sprays, whose field results have been politically contested. Ignoring debt and crop choice, as in Thai maize.

Where it comes from

Conservation agriculture and zero tillage, developed by public research (PAU, CIMMYT, ICAR) in the 2000s; the Happy Seeder came out of PAU and Australian collaborators. India's central Crop Residue Management scheme scaled subsidies from 2018. Open public knowledge; no custodial protocols. Local farmer knowledge of timing and soils should be credited in each place.

Where it's worked

  • Punjab and Haryana, northern India (rice to wheat systems) · Published Aug 2019

    Shyamsundar et al. in Science compared 10 residue practices: Happy Seeder systems were on average 10% to 20% more profitable than burning and could cut on-farm greenhouse gas emissions by up to 78%.

    Peer reviewedSource

  • Punjab, India · 2017-18 to 2018-19

    CAG audit: machine distribution targets met, but burning cases rose from 43,660 to 49,905, with irregular repeat subsidies and no monitoring of scheme performance.

    DocumentedSource

  • Punjab, India · 2023 to 2024

    Official fire counts fell 70% (36,551 to 10,479) as in-situ and ex-situ straw management expanded, including over 6.2 million tonnes handled ex-situ and thousands of subsidised balers and rakes.

    DocumentedSource

  • Punjab and Haryana, India · 2019 to 2025

    iFOREST burnt-area mapping from Sentinel-2 found Punjab's burnt area fell about 37% from the 2022 peak, far less than the 90% drop in official fire counts, because burning shifted after satellite overpass times.

    DocumentedSource

  • China (national) · 2001 to 2019

    Cao and Ma (Journal of Development Economics, 2023): biomass power plants that paid farmers for straw cut agricultural fires by 14%, while burning bans had limited effect and mainly reduced easier-to-spot night burning.

    Peer reviewedSource

  • Northern Thailand (Chiang Mai, Omkoi district) · 2013 to 2025

    Zero-burn periods, subsidy threats and microbial sprays have not significantly changed maize burning; Omkoi district dropped maize in 2017 for rotating vegetables and rice, but is threatened by a proposed lignite mine.

    Stories from the fieldSource

Where it failed

In Punjab, a CAG audit found crores spent on machine subsidies while burning rose from 43,660 to 49,905 cases between 2017-18 and 2018-19, with weak monitoring, poor awareness and repeat subsidies to the same farmers. Later headline drops in fire counts are partly an illusion: a 2025 iFOREST study found farmers shifted burning to late afternoon after satellite overpasses, so burnt area fell only about 37%, not 90%. In northern Thailand, zero-burn periods since 2013, subsidy threats and microbial sprays have not changed practice because burning stays cheapest for indebted maize farmers. In China, burning bans mostly just moved fires to times that are harder to see.
