Socio-cultural and ecological indicators of Canterbury estuaries

Abstract

Estuaries support a wide range of human activities and values, but are one of the most anthropogenically impacted ecosystems in the world. Ki uta ki tai (mountain to sea) is a holistic view of waterways, that is embodied within Ngāi Tahu whakapapa (genealogy) and environmental management practices. While ecosystem connectivity is well-recognised, current policies and management do not effectively account for this philosophy, or Ngāi Tahu environmental values and concepts. Identifying and understanding the risks to socio-cultural values is integral to the effective management and accountability of anthropogenic activities in our estuaries. This study evaluates the socio-cultural and ecological values of shellfish across four estuaries in Waitaha Canterbury.
