Global Pesticide Toxicity Rising Despite UN Biodiversity Pledge

Ecological damage from pesticides is increasing worldwide, with insects, soil organisms, fish, pollinators and terrestrial plants among the most affected, according to a new study. Between 2013 and 2019, toxicity to insects rose 42.9%, while harm to soil organisms climbed 30.8%. Only aquatic plants and land-based vertebrates saw declines in risk.

Researchers assessed 625 pesticides across 65 countries using the UN’s total applied toxicity (TAT) indicator, which measures harm across species groups. While Europe and China recorded declines—following pesticide restrictions—toxicity rose sharply in parts of Africa, India, the US, Brazil and Russia. Chile is the only nation currently on track to meet the UN goal of halving pesticide risks by 2030.

Scientists warn that growing pesticide use—now about 4 million tons annually—may be silently impairing ecosystems. They call for stronger global action, improved monitoring data and a shift toward less toxic and more sustainable farming practices.
