Integrating Spatial Data and Indigenous Knowledge Systems for Resilient Urban Planning: Lessons from South Africa

Johannesburg’s marginalised settlements are among the most dynamic urban environments globally. These locations have limited infrastructure resources, which have negatively impacted household livelihoods. There is a critical need for developing planning support systems to improve the quality of life in these communities. As part of the city’s transformation strategy, urban agriculture has emerged as a critical approach to enhancing food security and economic empowerment, particularly in marginalized areas. However, effective planning for urban agriculture necessitates spatial intelligence and community engagement. This study employs a mixed-method approach, combining indigenous knowledge systems with spatial data to assess land suitability. The findings present a land suitability index to inform spatial planning, demonstrating how integrating GIS and citizen science strengthens urban resilience through adaptive land use, improved local food systems, and climate change mitigation.
