Managing Coastal Sand Drift in the Anthropocene: A Case Study of the Manawatū-Whanganui Dune Field, New Zealand, 1800s–2020s

Abstract

In the Anthropocene, dunes act as a natural defence from sea-level rise and storm surges while providing ‘ecosystem’ services. This article uses scientific and historical data to examine the Manawatū-Whanganui dune field in New Zealand from the nineteenth to the twenty-first century. Dunes that were destabilised due to European settlements and their activities were drifting inland causing social, economic and political problems. Attempts to prevent dune mobility occurred at the time in many parts of the world. Thus, knowledge was shared between countries through experts and migrants. The consequences of the implemented solutions and new environmental conditions mean that dunes are still a major issue in the region. A comparative analysis of historical and present-day dune management practices provides a better understanding of long-term dune drift. In conclusion, interdisciplinary analyses of long-term relations between dunes and society must be taken into account for their holistic management.
