Ubuntu action for recovery of urban shorelines: a transdisciplinary approach to coastal ecological engineering in South Africa

Ocean sprawl—the proliferation of engineered infrastructure along rapidly urbanising coastlines— is transforming marine ecosystems, simplifying their structure and leading to the loss of critical habitat complexity, biodiversity, and diminished ecological functions. This research addresses these impacts through a non-conforming, transdisciplinary approach to coastal ecological engineering that prioritises innovative co-creation with Indigenous Peoples and Local Communities (IPLC) to enhance biodiversity and early stage functionality of urban shorelines. Based in South Africa’s Eastern Cape, our consortium integrates scientific, heritage, and ecomusicology perspectives to co-design nature-based, biodegradable structures using the native plant Cyperus textilis, while embedding community values and traditional knowledge throughout the research process. This presentation highlights best practices in transdisciplinary action research, illustrating how cultural expressions, such as weaving, can reframe coastal conservation efforts as both heritage preservation and a mean of youth engagement, fostering long-term stewardship.  Guided by Ubuntu principles, we established a framework grounded in equity and inclusion through trust-based relationships, local economic engagement, and educational material co-translated in isiXhosa. Reflecting on the successes and challenges, this project demonstrates a vibrant science-to-action transdisciplinary model, which aligns the too often forgotten IPLC voices with sustainable innovation and low-cost ecological solutions, advancing inclusive ocean decision-making and ecosystem rehabilitation practices rooted in community identity and heritage.
