Exploring local perceptions around the value of marine biodiversity: the case of kelp in the Western Cape, South Africa

Abstract

ABSTRACTKelp 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.
