  • Portrait of Joshua Webber, GIS & Avifaunal Sensitivity Mapping

    Joshua Webber

    GIS & Avifaunal Sensitivity Mapping

    Johannesburg, Gauteng MSc Zoology (UP), AfriAvian PhD candidate

    Joshua holds an MSc in Zoology from the University of Pretoria and is currently pursuing his PhD with an AfriAvian bursary. He joined the AfriAvian team in 2023, where he focuses on spatial data capture and data analysis, and is responsible for GIS and the mapping of avifaunal sensitivities across projects.

    With his PhD research, Joshua investigates spatiotemporal factors that shape collision risk for Black Harriers, one of Africa’s rarest raptors. By disentangling the climatic and ecological drivers of movement across the landscape, his work provides critical insight into how these birds interact with wind energy developments. The resulting data will underpin predictive algorithms designed to guide turbine placement and operations, helping wind farms reduce collision risk while supporting responsible renewable energy expansion.
