New Zealand appears, at first glance, to have avoided many of the worst excesses of coastal development and resource exploitation. In fact, the coasts of New Zealand bear little resemblance to their natural state before the arrival of Polynesians. We share a range of problems with similar developed nations. Deforestation and de-vegetation, displacement of native species by exotic plants and animals, unregulated waste disposal, pollution of estuaries and harbors, un-managed subdivision and development, careless fishing and over-fishing, have degraded the biology and biodiversity of coastal and marine environments. Sand and gravel mining, water abstraction and sand/gravel extraction from rivers, accelerated coastal erosion due to modified coastal sediment budgets, reclamation and inappropriate coastal engineering works have significantly changed the natural character of our coasts. These impacts were not inevitable, but arose from an ignorance of the geomorphic processes that shape New Zealand’s coasts and which are a fundamental to coastal ecosystems.
This paper explores three important themes in coastal geomorphology and coastal management: the development and degradation of aeolian systems (and the restoration of these systems); processes and patterns in the evolution of rocky coasts characterized by cliffs and rock platforms and; thirdly, late-Holocene barrier evolution in relation to changing patterns of sediment supply and eustatic sea-level. Within these themes there is scope to explore both geomorphic processes and social processes of coastal management; in fact the two are usually intertwined. However, we propose it is necessary to understand the former to achieve good coastal management.
This paper will appeal to students with an interest in the natural character of coasts and the link between coastal science and coastal management. What do we know about coasts? How is this knowledge used in coastal management and what should be our research priorities? We are fortunate at the University of Otago to have ready access to a wide range of temperate coasts - fiords, coastal barriers, sand and gravel beaches, rocky shores, cliffed coasts and transgressive dune systems, which are both remarkably natural and, in many cases, remarkably modified. We have opportunities to explore processes of environmental restoration, an emerging theme in coastal management. This paper will also appeal to students who enjoy fieldwork and discovering new and remote places. You will be required to participate in a group research project in one of the key theme areas (aeolian geomorphology, rocky coast geomorphology or barrier development). This research is the core element of the paper and will be completed during a 5-6 day residential field camp.
Students would normally be enrolled for a post-graduate degree (PG Dip Sci, PG Dip Arts, MSc, MPlan, MA etc.). Completion of papers GEOG298/398 and GEOG397 would be an advantage, but is not essential. The course is popular with science or planning students wishing to prepare for a career in coastal management with local authorities, consultancies or central government.
An advanced examination of coastal management in New Zealand and Australia. Emphasis is placed on issues associated with sandy coasts, including hazard management, invasive species, subdivision and development, and conservation management.
This paper will be of interest to both Arts and Science graduates who wish to advance their specific interests in coastal systems and costal management.
