Event description


Climate change is driving an increased threat of erosion and flooding along coastlines globally. Engineering solutions (e.g. seawalls and breakwaters) in response to protecting coastal communities and associated infrastructure are increasingly becoming economically and ecologically unsustainable. This has led to recommendations for creating or restoring natural habitats, such as sand dunes, saltmarsh, mangroves, seagrass and kelp beds and coral and shellfish reefs, to provide coastal protection in place of (or to complement) artificial structures.

Coastal managers are frequently faced with the problem of an eroding coastline, which requires a decision on what mitigating approach to take. A barrier to the wider use of nature-based coastal defence is stringent evaluation of their effectiveness in comparison to artificial protection structures.

In this webinar, Professor Stephen Swearer will discuss the current evidence for the efficacy of nature-based approaches in comparison to artificial coastal protection. He will then present several current and developing on-ground activities with local councils and land managers in Victoria as case studies to illustrate the types of collaborative interdisciplinary projects needed to encourage the wider use of ecologically engineered shoreline protection schemes in Australia.
