Using drone technology to improve mosquito control in Zanzibar (GeoLSM)
Objectives
The GeoLSM project — short for Harnessing geospatial technologies for operational Larval Source Management (LSM) in Zanzibar — is a malaria elimination initiative aimed at improving mosquito control using drone and geospatial technologies in Zanzibar.
Zanzibar has maintained very low malaria transmission, with cases remaining below 1% since 2006. However, researchers say existing interventions such as insecticide-treated bed nets (ITNs) and indoor residual spraying (IRS) may not be enough to completely eliminate malaria. Imported cases and outdoor mosquito transmission continue to sustain infections, creating a need for additional mosquito control strategies on the Island. The project focuses on improving Larval Source Management (LSM), an approach that targets mosquito breeding habitats using larvicides and environmental management. In Zanzibar, conventional LSM depends on ground teams to manually locate and map breeding sites. Researchers say this method is labor-intensive, costly and often less accurate.
GeoLSM project aims to develop and evaluate a technology-enabled LSM system that uses drones and geospatial information to identify mosquito breeding habitats more accurately and efficiently. The project will compare the new technology-based approach with conventional LSM methods to assess operational efficiency, cost-effectiveness and impact on mosquito populations and malaria transmission. Researchers will also investigate how environmental and water quality factors influence mosquito breeding and larval development. Weekly monitoring of breeding habitats will help assess how changes over time affect mosquito productivity and survival.
