Use of pesticides and risk perception of environmental contamination by farmers surrounding the Menoua River (West Cameroon).

This article focuses on the perception and practices of farmers in the Santchou area of West Cameroon regarding pesticide use and the associated risks of contamination to the Menoua River and its aquatic life. A cross-sectional survey of 150 farmers revealed widespread use of herbicides, insecticides, and fungicides—primarily glyphosate, paraquat, chlorpyrifos-ethyl, dieldrin, copper oxide, and mancozeb—with pesticide sellers serving as the main advisers rather than government agricultural technicians. Despite nearly half of the farmers acknowledging potential contamination risks to river water and fish, most did not adhere to recommended pesticide doses or use protective equipment, and many used river water to mix pesticides, potentially increasing environmental and health hazards. The study highlights a disconnect between farmers’ risk awareness and their behaviors, underscoring the need for enhanced education and support from qualified agricultural and environmental authorities to improve pesticide management and safeguard both human health and aquatic ecosystems in the region.
