Organic farming linked to lower pesticide exposure among smallholder farmers
Exposure to pesticides and associated risks including increased cancer rates and neurological disease, are of special concern to farmers navigating pest management challenges in tropical environments. A recent study found that organic practices offer protection from these risks for smallholder farmers in Costa Rica and Uganda.
Researchers were interested in comparing pesticide exposure in three types of farming systems: conventional, mixed production, and organic. They collected
Across both countries, pesticide biomarkers were detected in nearly all participants, demonstrating widespread exposure among farmers regardless of system. However, relative to conventional systems, organic farming was consistently associated with lower pesticide exposure, reducing biomarker concentrations by as much as 68%. Mixed farming operations, which included both synthetic and non-synthetic pesticide use, was also linked to lower concentrations, though reductions were smaller than those observed in organic systems.
The study also found that pesticide safety training was associated with positive outcomes, particularly for insecticides. Farmers who had received training on safe pesticide handling showed reductions in some biomarker concentrations, highlighting the importance of education and practical support for reducing pesticide related risks.
These findings emphasize the important role that organic farming and pesticide safety education can play in reducing occupational risk among smallholder farmers. While widespread transition to organic management will require holistic support so farmers can reduce pesticide use without risking yield or economic hardship, studies like this strengthen the body of evidence supporting the protective nature of organic, especially for producers.
