Kelp are large seaweeds that provide a variety of contributions to humans and the environment. In South Africa, kelp forests are expanding as a consequence of climate change. Considering this expansion, assessing local perceptions and values around kelp's contributions may assist with the implementation of inclusive management strategies. The lack of consideration of non-market and non-use values is a gap in kelp valuation studies, with kelp ecosystems and their use rarely valued outside of classical economic valuation frameworks. This study sought to fill this research gap, intending to assess local perceptions about varied value dimensions associated with kelp using a pluralistic valuation approach. Drawing from a sample population of Recreational Users and/or Coastal Community Members, Environmental Managers and Conservationists, and Kelp and/or Abalone Industry, the study investigated perceptions of value towards kelp in the Western Cape region of South Africa. Results indicate that the perceived value of kelp extends far beyond its economic value as a harvested resource. Rather, individuals highly value kelp's ecological and social contributions, and have strong relational values towards kelp, recognizing its role in enhancing their quality of life and well-being. While most individuals did not display significant negative perceptions around kelp, some individuals in the Kelp and/or Abalone Industry indicated frustrations with kelp management strategies and kelp concession permit allocation processes. These findings highlight the need to incorporate local perceptions in integrated marine resource management solutions that recognize the plurality of values not only around kelp in the Western Cape but marine biodiversity at large.

Increasing anthropogenic pressure on the sea and alteration of coastscapes challenge the functioning of marine ecosystems and long-term reliance on blue economies, especially for developing southern economies. The structural hardening of shores can result in ecological disruptions, with cascading effects on the wellbeing and livelihoods of marginalised groups who depend on marine resources. Mitigation, adaptation and rehabilitation options for coastal developments should include innovative, socially responsible solutions to be used to modify shorelines and ensure long-term functionality of metropolitan coastal ecosystems. Nature-based innovations are being developed to improve surrogacy for natural marine ecosystems. The co-creation of nature-based structures, entailing partnerships between scientists and a local rural community is currently being considered in South Africa and we present this regional case study as a transdisciplinary framework for research in nature-based, ecological engineering of coastal systems. Novel transdisciplinary approaches include ecomusicological interventions, where traditional cultural expressions (TCEs) create opportunities for transgressive pedagogy. This step aims to ensure that the knowledge gathered through nature-based scientific research remains a part of community developed Indigenous knowledge systems. The merging of innovative, eco-creative approaches and TCEs has the potential to sustainably and ethically improve the functioning and diversity of coastal urban habitats. This review tackles the potential of transdisciplinary settings to transform urban coastlines using "low-tech" engineering and Indigenous eco-creative innovations to pedagogy, to benefit the people and biological communities as well as reduce social and gender inequalities.
