    Spatial analysis of risk mitigation for preservation of heritage value in Mapungubwe Historic Site
    (2026-05-19) Mabulela, Vuledzani; Moffat, F.; Gondo, T.
    This study investigated the spatial dynamics of risk mitigation for the preservation of heritage value within the Mapungubwe Historic Site, a World Heritage site of outstanding cultural and ecological significance in Vhembe, Limpopo Province, South Africa. The research aimed to identify and categorize risks threatening seven key heritage sites (K2, Schroda, Mapungubwe Hill, Pont Drift, Little Muck, Mona, and Welton), evaluate existing mitigation measures, assess the vulnerability of heritage resources, and develop strategies to enhance preservation outcomes. A mixed-methods approach grounded in positivist principles was adopted, integrating quantitative spatial analysis using Geographic Information Systems (GIS) and remote sensing with qualitative insights from secondary data sources utilizing the PRISMA technique. Hierarchical Cluster Analysis (HCA) and spatial vulnerability assessments were employed to analyze natural, ecological, and socio-economic risks, including erosion, climate variability, land-use changes, tourism pressures, and human interference. The evaluation of existing mitigation measures revealed strengths in adaptive management, zoning, cultural heritage protection, and biodiversity conservation, but also highlighted gaps such as limited community participation, resource constraints, reactive response mechanisms, and insufficient integration of monitoring data into decision-making. The findings indicated that vulnerability patterns were spatially heterogeneous, with certain sites exhibiting higher susceptibility to environmental and anthropogenic pressures. Based on these results, enhanced risk mitigation strategies were proposed, including proactive climate adaptation measures, strengthened community engagement, technology-driven monitoring (GIS), dynamic visitor management, and diversified funding mechanisms. The study contributed to a clearer understanding of how spatial analysis informed targeted heritage preservation strategies, providing a framework for safeguarding Mapungubwe’s cultural and ecological assets while promoting sustainable management practices.
