Desert Locust Management Is Plagued by Human-Based Impediments

Technical aspects of desert locust (Schistocerca gregaria) management have markedly improved since the late 1980s. Examples include modernized electronic communication systems linking stakeholders, global positioning system precision for reporting and treatment of locust aggregations, ultra-low-volume insecticide formulations and application techniques that reduce both environmental impact and chemical use, and computerized integration of multidisciplinary data for monitoring and forecasting outbreaks, upsurges, and plagues. Despite the remote and rugged terrain where the species thrives, tools and vehicles for surveillance and control generally exist—although they are not always available when needed. As technical aspects of desert locust control continue to be surmounted, human-based factors remain substantial, underlying, multifaceted obstacles. Funding shortfalls are frequently cited but rarely analyzed in depth. This article focuses on these underlying human constraints, including rigid conceptual dogmas, diverse forms of insecurity, political interference, weak communication among stakeholders, decreasing donor interest, confusion between emergency response and development objectives, loss of institutional memory, inadequate staff training, and limited attention to dynamic, real-time developments. These human-based impediments are critical because they underlie systemic unpreparedness and hinder the transition toward more integrated, proactive, and sustainable locust management approaches. As such, they contribute to the onset, intensity, and prolonged duration of desert locust episodes.
