🗞️ Why in News A February 5, 2026 study published in the journal Science by researchers at the University of Kaiserslautern-Landau, Germany, found that pesticide toxicity is rising globally, with India, China, Brazil and the US driving 53-68% of global pesticide toxicity. India’s Indo-Gangetic plains show toxicity levels exceeding the global average.

The Study — Key Framework

  • Reviewed 625 pesticides used globally across 201 countries (2013-2019)
  • Assessed impact on eight species groups: pollinators, aquatic invertebrates, fish, soil organisms, terrestrial arthropods, terrestrial plants, birds and mammals
  • Uses Total Applied Toxicity (TAT) — a metric formally adopted at CBD COP16 (2025) — which weighs pesticide volume against toxicity to specific species groups
  • Purpose: track progress towards the Global Biodiversity Framework goal to halve pesticide risks by 2030 (relative to 2010-20 levels), adopted at CBD COP15 (2022)

Global Findings

  • Of 65 countries with national data (covering 79.4% of global crop acreage), only Chile is on track for the 2030 halving goal
  • China, Japan and Venezuela are moving closer to the target
  • Thailand, Denmark, Ecuador and Guatemala are moving away — with at least one toxicity indicator doubling in 15 years
  • Even where total pesticide volume appears stable, ecological impact is intensifying for six of eight species groups
  • Steepest global rise: terrestrial arthropods (insects) at 6.4% per year, followed by soil organisms at 4.6% per year
  • Reversing entrenched toxicity trends requires “systematic transformation” — integrated biological solutions, precision agriculture, informed farmer practices, and supportive policies

The “Toxic 20” Problem

  • Only 20 highly toxic pesticides (out of 511 analysed) dominate over 90% of a country’s total toxicity burden
  • Organophosphates and pyrethroids dominate toxicity for aquatic invertebrates, fish, and terrestrial arthropods
  • Neonicotinoids account for the bulk of pollinator toxicity — critical given the global pollinator crisis
  • Herbicides contribute heavily to plant toxicity:
    • Acetochlor: ~54,000 metric tonnes/year
    • Paraquat: ~44,000 tonnes/year
    • Glyphosate: ~518,000 tonnes/year (most widely used herbicide globally)
    • All three linked to environmental and human health risks
  • Fungicides significantly affect soil organisms

India’s Heavy Burden

Rising Pesticide Use
  • Chemical pesticide use increased ~20% — from 57,353 tonnes (2014-15) to 67,221 tonnes (2024-25)
  • Source: Directorate of Plant Protection, Quarantine and Storage (DPPQS), Union Ministry of Agriculture
Per-Hectare Intensity Above Global Average
  • Indo-Gangetic plains show toxicity levels exceeding the global average
  • Intensively cultivated regions with high per-hectare toxicity: Punjab, Haryana, Gujarat, Maharashtra, Telangana, Karnataka
  • Toxicity is accelerating (2013-19) across large parts of India and South Asia
Toxicity by Crop Type
  • India’s pesticide burden is closely linked to staple cereals (rice), cotton, and sugarcane
  • Cotton has a disproportionately high toxicity contribution despite occupying a smaller share of farmland compared to rice — reflects heavy insecticide dependence in cotton cultivation
  • India is the world’s largest cotton producer and among the largest consumers of insecticides for cotton

Regulatory Gaps — The “Silo” Problem

Pesticide Management Bill, 2025
  • Released as a draft on January 7, 2026 by the Ministry of Agriculture and Farmers Welfare
  • Aims to replace the Insecticide Act, 1968 (not updated in over 5 decades)
  • States it will “strive to minimise risk to human beings, animals, living organisms other than pests, and the environment”
  • Criticism (PAN India): Language is weak — “strive to minimise” is non-binding and lacks enforceable standards
Legislative Silos
  • The Pesticide Management Bill, 2025, and the Biological Diversity Act, 2002 operate in separate legislative silos — different ministries, no formal connection
  • Narasimha Reddy Donthi (Pesticide Action Network India): “The TAT framework makes that separation indefensible”
  • India must adopt the TAT framework and include the National Biodiversity Authority (NBA) in pesticide regulation
  • Demand: pesticide registration, renewal, and phaseout decisions must carry a mandatory biodiversity impact assessment conducted by the NBA
The Missing Link
  • “The Bill is on the table. The Biodiversity Act is in force. What is missing is the political will to treat biodiversity loss as a consequence of pesticide approval” — Donthi

Critical Evaluation for UPSC Mains

Why India’s Situation is Structurally Different
  • India has one of the world’s largest agricultural areas — even modest per-hectare toxicity translates into a massive cumulative ecological burden
  • Green Revolution legacy: chemical-intensive agriculture deeply embedded in Punjab-Haryana belt
  • Subsidy structure (fertiliser + pesticide) incentivises overuse rather than integrated pest management (IPM)
  • Informal pesticide markets and low farmer awareness compound the problem
What Needs to Change
  1. Adopt TAT framework at the national level for pesticide risk assessment
  2. Mandatory biodiversity impact assessment for all pesticide approvals — involve NBA
  3. Accelerate IPM adoption — India’s National IPM Centre exists but coverage remains limited
  4. Precision agriculture technologies — drone-based targeted spraying, soil-testing based recommendations
  5. Phase out highly hazardous pesticides (HHPs) — India still permits several chemicals banned in the EU
  6. Strengthen the Pesticide Management Bill — replace “strive to minimise” with enforceable, measurable standards
Inter-linkages
  • Health: Pesticide residues in food and groundwater → cancer clusters in Punjab (“cancer train”), endocrine disruption
  • Trade: EU’s stringent Maximum Residue Limits (MRLs) block Indian agricultural exports → economic cost of non-compliance
  • Pollinators: Neonicotinoid toxicity threatens pollination services worth billions annually — directly impacts crop yields
  • Soil health: Fungicide impact on soil organisms undermines long-term agricultural productivity
  • Water: Pesticide runoff contaminates rivers and groundwater — impacts downstream communities

UPSC Angle

  • Prelims: TAT metric, CBD COP15/COP16, Global Biodiversity Framework, Insecticide Act 1968, Biological Diversity Act 2002, NBA, neonicotinoids, organophosphates
  • Mains GS-3: Agriculture — pesticide regulation, IPM, precision agriculture, biodiversity loss from farming, environmental pollution, food safety
  • Mains GS-2: Governance — legislative silos, regulatory reform, Pesticide Management Bill 2025
  • Essay: “The cost of feeding billions — when the cure poisons the soil”
