Nearly half of the world's farmers, an estimated 402 to 433 million individuals, experience unintentional acute pesticide poisoning annually, according to a comprehensive new study. The research, which analyzed publicly available data from 2006 to 2023, highlights a significant global health crisis affecting those who cultivate the world's food.

The study, commissioned by the Pesticide Action Network and published in the journal Frontiers in Public Health, bases its findings on a global farming population of 934 million. This equates to approximately 46% of farmers and farm workers being poisoned each year. The regions with the highest estimated number of poisonings include southern Asia, followed by south-east Asia and east Africa.

Beyond the widespread cases of poisoning, the research also estimates that 11,000 deaths occur annually as a direct result of pesticide exposure. India accounts for nearly 60% of these fatalities, underscoring the severity of the issue in the country. Jayakumar Chelaton, executive director of Pesticide Action Network India, described the findings as exposing a "crisis that can no longer be ignored."

Authors of the study are urging immediate action from global bodies and governments. They are calling for the implementation of a United Nations recommendation to phase out highly hazardous pesticides. Despite growing awareness of the dangers, global pesticide use has continued to climb, reaching 3.8 million tonnes in 2023, a doubling since 1990.

Dr. Sheila Willis, head of international programmes at Pesticide Action Network UK, emphasized the need for support for farmers. "Now that the scale of suffering has been revealed, farmers must be supported to access safer alternatives to protect their health and that of their families," she stated.

The study focused specifically on unintentional acute poisonings among adult farmers and farm workers. It did not include an assessment of the impacts on the estimated 84 million children who also work in agriculture or consider the long-term effects of chronic pesticide exposure.

While the study did not detail specific countries beyond highlighting regional trends and India's high fatality rate, it noted that Burkina Faso in west Africa reported the highest national incidence, with nearly 84% of its farmers and farm workers experiencing poisoning. This figure suggests a critical need for targeted interventions in regions with the most acute levels of exposure.

Experts involved in the research are advocating for a multi-pronged approach that includes improved safety training, better access to personal protective equipment, and the promotion of integrated pest management strategies that reduce reliance on chemical pesticides. The continued rise in pesticide use, despite documented risks, points to complex economic and agricultural system factors that need to be addressed.
