Descripción
The Ugandan dairy sector has expanded rapidly in recent years. However, ticks and tick-borne diseases pose increasing challenges to this progress, exacerbated by the rise in resistance to acaricides, the primary method for tick control. This paper examines the systemic constraints that undermine effective, safe, and sustainable tick control in Uganda’s liberalized dairy system. Drawing on multiple complementary data sources—including household surveys, exit interviews, list experiments, and covert audit methods—we show that the de facto farmer-led model of tick control is characterized by failures in information, coordination challenges, imperfect input markets, and weak regulation. Farmers operate with limited technical knowledge and minimal advisory support, and under extensive grazing systems and frequent inter-herd contact that require coordinated approaches to tick control. Input markets provide access to acaricides, but little guidance on proper use. As a result, misuse and overuse of chemicals are widespread, generating risks for animal and human well-being, food safety, and environmental integrity. Addressing these constraints will require integrated interventions that strengthen extension and regulatory capacity, improve accountability in veterinary input markets, and foster community-level coordination to ensure safe and sustainable tick control.
