1. Global Rise in Total Applied Toxicity (TAT) and the UN Biodiversity Target

The 2022 United Nations Biodiversity Conference (Kunming-Montreal Global Biodiversity Framework) committed countries to reduce pesticide risk by 50% by 2030. This target links biodiversity protection with human health and sustainable agriculture, making it central to SDGs 2 (Zero Hunger), 3 (Health), 12 (Responsible Consumption), and 15 (Life on Land).

However, a recent study published in Science shows that instead of declining, Total Applied Toxicity (TAT) increased globally between 2013–2019. For the first time, researchers assessed toxicity across 600+ pesticides in 65 countries, measuring impact on non-target species such as pollinators, soil organisms, fish, terrestrial arthropods, and plants.

The findings indicate that rising pesticide volumes and the increasing use of more toxic formulations have collectively elevated ecological risk. Only Chile is currently on track to meet the 2030 target, while major agricultural producers are not.

The governance logic is clear: without measurable reduction in toxicity—not just volume—the UN biodiversity commitments risk becoming symbolic. Failure to reverse the trend will undermine ecosystem services essential for food security and economic stability.

Key Data:

  • 50% reduction target by 2030 (UN Biodiversity Conference, 2022)
  • 600+ pesticides, 65 countries studied
  • 2013–2019 study period
  • Only Chile on track

2. India’s Contribution to Global Applied Toxicity

India is among four countries—China, Brazil, the U.S., and India—that together account for nearly 70% of global TAT. Toxicity increased in India during the study period, especially affecting terrestrial arthropods, soil organisms, and fish.

Pesticides are extensively used on high-value crops such as fruits, vegetables, maize, soybean, rice, and cereals. While these inputs enhance yield, their ecological cost is disproportionately borne by non-target species.

Particularly concerning are rising TAT levels in sub-Saharan Africa, parts of the Indian subcontinent, and southern Australia, indicating that developing agricultural economies are witnessing heightened ecological stress.

India’s agricultural growth model, rooted in Green Revolution-era chemical intensification, has improved food security but now faces sustainability limits. If toxicity continues to rise, it may jeopardise long-term soil health, pollination services, and export competitiveness.

Major Contributors to Global TAT:

  • China
  • Brazil
  • United States
  • India (~70% combined contribution)

Most Affected Non-target Species:

  • Terrestrial arthropods (highest impact)
  • Soil organisms
  • Fish
  • Invertebrates and plants

3. Biodiversity and Ecological Implications

Non-target species play critical roles in agroecosystems—pollinators enhance crop productivity, soil organisms maintain fertility, and aquatic organisms sustain freshwater ecosystems. Increased TAT directly threatens these ecological foundations.

The study highlights that toxicity rose particularly among:

  • Invertebrates
  • Terrestrial plants
  • Soil organisms
  • Fish

Such degradation weakens ecosystem resilience, intensifies pest resistance cycles, and increases dependency on chemical inputs—creating a negative feedback loop.

Rachel Carson’s warning remains relevant:

“If we are going to live so intimately with these chemicals eating and drinking them, taking them into the very marrow of our bones,” we had better know something about the power of the “who’s who of pesticides.” — Rachel Carson, Silent Spring (1962)

Biodiversity loss is not merely an environmental issue; it directly affects agricultural productivity, rural livelihoods, and climate resilience. Ignoring pesticide-linked ecological damage could compromise both food security and environmental stability.


4. Human Health and Urban Exposure Risks

The pesticide issue extends beyond farms into urban and domestic spaces. Reports indicate increasing exposure through pest control treatments, wall paints, incense sticks, stored grains, aircraft cabins, and even food offerings.

A tragic example cited involved the death of two children in Chennai following pest control treatment. Such incidents highlight regulatory gaps in “ordinary use” pesticides outside agricultural fields.

Globally, concerns are rising over “pesticide cocktails” and “forever chemicals” found in food products such as apples and imported roses. The European Union has rejected consignments of Indian basmati rice due to fungicide residues banned in Europe.

When pesticide regulation fails to address cumulative exposure and chemical persistence, public health risks escalate. This can also affect trade relations and export credibility, linking environmental governance to economic diplomacy.

Emerging Concerns:

  • “Forever chemicals” in food products
  • Residue-based rejection of exports
  • Urban and domestic pesticide exposure

5. India’s Regulatory Framework: Gaps and Reform

India’s pesticide regulation is governed primarily by the Insecticides Act, 1968, which was designed for agricultural usage patterns of the 1960s. It lacks robust provisions for modern, widespread domestic and commercial use.

India reportedly uses at least 66 pesticides banned elsewhere, including paraquat (banned in Europe). Concerns exist regarding persistence in soil, water, and food chains.

The proposed Pesticides Management Bill, 2025 seeks to:

  • Reduce risk to people and environment
  • Promote biological and traditional knowledge-based pesticides
  • Update regulatory mechanisms

However, experts caution that without strong liability provisions and expert-driven reforms, it may not sufficiently address structural problems.

Effective pesticide governance requires moving from mere registration and control toward accountability, liability, and long-term agroecological transformation. Without this shift, regulatory reform may remain procedural rather than substantive.

Regulatory Issues:

  • Outdated 1968 framework
  • Weak liability mechanisms
  • Continued use of globally banned chemicals
  • Limited monitoring of non-agricultural use

6. Monitoring, Data Transparency, and International Cooperation

The study underscores the need for countries to regularly report annual pesticide use data, disaggregated by active ingredient. This would enable real-time tracking of progress toward UN targets.

Currently, data gaps hinder accurate assessment and international accountability. Transparent reporting can support evidence-based policymaking and global comparisons.

Countries such as China, Japan, and Venezuela showed declining trends in applied toxicity, suggesting that policy shifts and regulatory tightening can yield measurable outcomes.

Without systematic data reporting and international coordination, biodiversity commitments risk lacking enforcement mechanisms. Monitoring is central to translating global pledges into national action.


7. Way Forward: Towards Sustainable Pest Management

Meeting the 2030 target requires structural transformation rather than incremental adjustment.

Policy Measures:

  • Gradual shift to less-toxic pesticides
  • Promotion of organic agriculture
  • Integrated Pest Management (IPM)
  • Strong liability and compensation mechanisms
  • Regular national pesticide-use reporting

Structural Reforms:

  • Move beyond Green Revolution chemical-dependence
  • Align pesticide policy with climate adaptation strategies
  • Strengthen residue monitoring for export competitiveness

The challenge lies in balancing food security with ecological sustainability, especially in agrarian economies like India.

Reducing pesticide toxicity is not anti-agriculture; it is pro-sustainability. If integrated reforms are delayed, biodiversity loss, trade barriers, and public health costs may outweigh short-term productivity gains.


Conclusion

The rising global Total Applied Toxicity trends indicate that the UN’s 2030 pesticide reduction target is currently off track. For India, the issue intersects biodiversity conservation, public health, agricultural sustainability, and trade competitiveness.

A calibrated shift toward safer alternatives, robust regulation, transparent monitoring, and agroecological transformation is essential to align national agricultural policy with global biodiversity commitments and long-term developmental goals.

Quick Q&A

Everything you need to know

Total Applied Toxicity (TAT) measures the overall environmental and ecological impact of pesticides applied in agriculture, factoring in both the quantity used and their toxicity to non-target species such as pollinators, aquatic life, soil organisms, and terrestrial arthropods.

Concerns for India and biodiversity:

  • India is among the top four contributors globally, responsible for nearly 70% of TAT, along with China, Brazil, and the U.S.
  • The increasing TAT threatens critical ecosystem services, including pollination, soil fertility, and aquatic food chains, which are essential for sustainable agriculture.
  • High toxicity also poses risks to human health through contaminated food, water, and air, with chronic exposure linked to neurological, reproductive, and metabolic disorders.

Research from 2013-2019 shows that India’s pesticide TAT has increased, particularly affecting terrestrial arthropods, soil organisms, and fish. Without mitigation, these trends compromise global biodiversity targets set under the UN 2030 agenda and raise serious public health concerns.

Excessive use of pesticides: Indian agriculture relies heavily on chemical pesticides to enhance crop yields. This includes at least 66 chemicals banned in other countries, such as paraquat, leading to higher environmental persistence and toxicity.

Outdated regulatory framework: The Insecticides Act, 1968, primarily focuses on agricultural applications, ignoring widespread household, commercial, and industrial use. Over decades, pesticide composition, toxicity, and application methods have evolved, but the regulatory framework has not kept pace.

Impact on human health and biodiversity:

  • Collateral toxicity affects non-target species critical for ecosystem stability, including pollinators and soil organisms.
  • Residues in food, water, and household products increase chronic exposure risks, exemplified by cases like the 2014 Chennai child deaths from pest-control exposure.
  • High TAT also disrupts ecological balance, impacting fish, amphibians, and terrestrial vertebrates, which can have cascading effects on agriculture and food security.

Thus, the combination of high-volume use, persistent chemicals, and inadequate legal safeguards amplifies both human and ecological vulnerability.

Shift to less-toxic and biological pesticides: Promoting biopesticides, organic farming, and traditional knowledge-based pest management reduces harmful environmental and health impacts.

Policy and regulatory reforms: The Pesticides Management Bill, 2025, aims to modernize pesticide governance, incorporating risk-based regulation, safety standards, and liability mechanisms. Success depends on expert inputs, monitoring, and enforcement.

Monitoring and reporting: Comprehensive annual reporting of pesticide use by active ingredient and toxicity level is essential. Real-time tracking enables assessment of progress toward UN 2030 goals.

Awareness and capacity building: Educating farmers, vendors, and consumers on safe pesticide practices, crop rotation, integrated pest management, and proper storage can mitigate risks. Examples from Chile, which is on track for the UN target, demonstrate that policy, monitoring, and farmer engagement collectively reduce TAT effectively.

Intensification of agriculture: Countries, including India, have increased both the volume and potency of pesticides to maximize crop productivity and meet food security goals.

Use of banned or persistent chemicals: Substances banned in Europe or other jurisdictions, such as paraquat, continue to be used in India, resulting in persistent residues in soil, water, and food products.

Lack of regulatory adaptation: Antiquated laws, weak enforcement, and insufficient monitoring fail to prevent overuse or misuse.

Collateral impacts: Non-target species, such as pollinators, fish, soil organisms, and terrestrial plants, are increasingly affected, undermining ecological balance. Evidence from global studies shows that TAT has risen for most major crops, especially fruits, vegetables, cereals, and soy, threatening biodiversity and ecosystem resilience.

Limitations of current governance:

  • The Insecticides Act, 1968, is outdated, primarily addressing agricultural use, ignoring household and industrial exposure.
  • Enforcement is fragmented and monitoring is inconsistent, allowing widespread use of banned or highly toxic pesticides.
  • Liability mechanisms for misuse and environmental damage are weak, reducing accountability.

Potential risks of the new bill: While the Pesticides Management Bill, 2025, aims to modernize regulation, insufficient consultation with experts and civil society may result in loopholes. Without stringent implementation, the bill could fail to reduce toxicity or even inadvertently increase chemical use.

Way forward: A successful framework requires risk-based regulation, liability provisions, promotion of organic and less-toxic alternatives, periodic review of active ingredients, and integration of farmer education programs. Cross-sectoral coordination between agriculture, environment, and health ministries is crucial to mitigate ecological and human health risks.

Several incidents demonstrate the risks of pesticide misuse in India. For example:

  • Chennai, 2014: Two children died after exposure to a pest control treatment in a residential apartment, highlighting risks beyond agricultural settings.
  • Food contamination: Indian basmati rice exports were recently rejected by the EU due to residues of fungicides banned in Europe, indicating persistent chemical exposure affecting trade and human health.
  • Everyday exposure: Pesticides now occur in paints, incense, furniture, temple prasad, and household surfaces, demonstrating how persistent chemicals permeate daily life, often unnoticed.

These examples underscore the need for stricter regulation, monitoring, and public awareness to prevent health hazards and preserve biodiversity.

Case study approach: Countries like Chile demonstrate that systematic monitoring, reduced use of toxic pesticides, and adoption of organic farming methods can align agricultural practices with biodiversity targets.

Recommended steps for India:

  • Phase out highly toxic and persistent chemicals, especially those banned internationally.
  • Promote integrated pest management (IPM) and biological alternatives, leveraging traditional knowledge.
  • Introduce robust monitoring, reporting, and liability mechanisms for pesticide use, covering agricultural, household, and industrial applications.
  • Educate farmers, retailers, and consumers on risks and safe usage.

Implications: Aligning agriculture with biodiversity objectives ensures long-term food security, safeguards ecosystem services, and protects human health. India’s commitment to the UN Biodiversity target requires both regulatory reform and cultural shifts in agricultural practice.
